## Veille

Interview with Boris Cherny (creator of Claude Code, Anthropic) at a Sequoia event (hosts: Asia, Lauren Reader). Cherny states ***"coding is solved"***: he himself has written **0 lines of code** since late 2025, the model writes **100%**, *"a few dozen PRs/day, 150 PRs in a single day record"*. Account of the genesis of Claude Code (Anthropic Labs incubator late 2024, Mike Krieger in charge of round 2, pre-PMF build *"for the next model"*, a first release that didn't take off, **exponential growth started with Opus 4 in May 2025**, accelerating with each new model 4 → 4.5 → 4.6 → 4.7). Current personal setup: **"most of my work I do from my phone"** (iOS), 5-10 sessions, **"a few hundred agents going, a few thousand at night"**, **`/loop` is the future** (cron + repeat jobs, agents babysitting CI, rebasing PRs, clustering Twitter feedback). **Routines** = the server-side equivalent, running with the laptop closed. SaaS outlook: no apocalypse, but a **reshuffling of Helmer's 7 Powers framework** (switching costs ↓, process power ↓, network effects/scale economies/cornered resources unchanged) and **10× more disruptive startups** over the next 10 years. Pivot analogy: the **Gutenberg press** (10% literacy in the 1400s → 70% over the following centuries, books 100× cheaper within 50 years), *"software will be similarly democratized, but faster than 50 years"* — *"the best person to write accounting software is not an engineer, it's a really good accountant."*

## Authors

Boris Cherny (créateur de Claude Code, Anthropic) interviewé par Lauren Reader (Sequoia) avec introduction d'Asia (Sequoia).

## Ton

**Profile**: A live interview in conversational format before an audience of Sequoia founders/investors/builders (*"as a roomful of builders"*, applause, show-of-hands polls several times). Hybrid keynote-Q&A format with 6 audience questions. Audience present: operators, founders, Sequoia early-stage investors; broadcast audience: the global tech community via Sequoia Capital's YouTube. Cherny needs no introduction to this audience — the intro is mostly comic (*"Boris is the father of Claude Code"*, *"Claude code psychosis"*).

**Style**: Cherny speaks casually, in the first person, with unaffected natural hesitations (*"like"*, *"you know"*), the vocabulary of a builder rather than an evangelist. He alternates between **quantified anecdote** (*"there was a day last week I did like 150 PRs in a day. That was a record"*), **lived origin story** (the genesis of Claude Code told as a mini startup novel), **bold vision** (*"coding is solved"*, the *"SaaS apocalypse"* analysis) and **self-deprecation** (*"My team lovingly says I have Claude code psychosis"*, *"It's extremely embarrassing, so please don't search it"* about a BASIC guide for the TI-83 Plus written in middle school).

**Crafted metaphors**:
- ***"Product overhang"***: *"the model can do all the stuff that no product has yet captured"* — a central concept for understanding the Claude Code strategy (build for the next model).
- ***"Coding is solved"***: a provocative statement with the weight of an aphorism.
- ***"Loops are the future"***: the conceptual pivot on the new agentic architecture primitive.
- ***The Gutenberg press analogy*** (1400s, 10% literacy → 70%, books 100× cheaper within 50 years) — the most structuring historical metaphor of the talk. *"Software will be similarly democratized, but faster than 50 years."*
- ***"The best person to write accounting software is not an engineer, it's a really good accountant"*** — a pivot phrase on democratization and the rebalancing of domain expertise vs. coding.

**Epistemic stance**: Cherny rejects both excessive caution (*"coding is solved"* is a radical statement) and blithe triumphalism (he sets out limits: *"this is not the case everywhere — there's very big complicated codebases, weird languages the model isn't good at yet"*). He embraces **prediction** as an exercise (*"I'm here to make predictions, so I'll try to make some"*) and structures his predictions through **established frameworks** (Helmer's 7 Powers) rather than free speculation.

**Authority**: built through (a) institutional standing (creator of Claude Code, lead of the most-discussed product in the agentic ecosystem), (b) **radically dogfooded practice** (100% code generated, 150 PRs/day record, iOS-only setup), (c) narrative humility (the account of *"it just really didn't work for the first 6 months"*), (d) the reversed power dynamic with the audience (*"Show of hands, who here uses Claude Code?"* — the majority of hands go up, the speaker no longer needs to establish legitimacy).

## Pense-betes

- **Date / source**: Sequoia Capital video interview (YouTube), URL https://www.youtube.com/watch?v=SlGRN8jh2RI. Exact date not visible in the transcript; internal references (*Opus 4.7* as the current model, *"we also just launched routines"*) place it in **late April / early May 2026**. Date added to the watch dossier: 2026-05-05.
- **Speaker**: **Boris Cherny**, creator of Claude Code, Anthropic. **Interviewer**: Lauren Reader (Sequoia). **Intro**: Asia (Sequoia).
- **Cherny's background revealed**:
- YC alumnus, first employee at a YC company, several past startups.
- Author of the book *"Programming TypeScript"*.
- **Hasn't written a single line of code in 2026** (statement made at Sequoia before the interview).
- Middle school anecdote: wrote a BASIC guide for the TI-83 Plus, *"still on the internet, extremely embarrassing"*.
- **Comic opening**:
- *"Show of hands, who here uses Claude Code?"* → majority.
- *"Show of hands, who here has Claude code psychosis?"* → laughter.
- *"My team lovingly says I have Claude code psychosis, which may or may not be true."* ### History of Claude Code (new account)
- **Origin**: Cherny joins **Anthropic Labs** in late 2024 — Anthropic's internal incubator, a team of a few people.
- **Anthropic Labs output**: Claude Code, MCP, desktop app. Team **disbanded** once the mission was accomplished.
- **Current round 2**: team reformed, led by **Mike Krieger** (Anthropic Chief Product Officer, ex-Instagram co-founder).
- **Why Cherny started coding**: *"product overhang"* — *"the model can do all the stuff that no product has yet captured."*
- **State of the art in coding, late 2024**: *"type ahead"* (open IDE, press tab, complete one line). This is what Sonnet 3.5 had unlocked.
- **The bet**: go further — *"the model was almost ready for the next big step. So we don't have to do type ahead anymore, we can just have the agent write all of the code."*
- **First 6 months**: *"it just really didn't work. It was like not very good. It was barely usable. I used it for maybe 10% of my code."*
- **First Claude Code release**: *"It was not a hit. There's a lot of people that used it, but it did not have this exponential growth that it has today."*
- **Inflection point**: ***Opus 4 in May 2025***. *"That's like when the exponential growth started, and then it kind of inflected with every model release. It started with Opus 4, then 4.5, then 4.6, now 4.7. It just kind of keeps inflecting."*
- **A deliberate pre-PMF bet**: *"essentially we were trying to build this thing that was pre-PMF, and we knew that it wouldn't have PMF for 6 months because we were building for the next model."* ### "Coding is solved"
- Show-of-hands poll:
- *"Who writes 100% of their code by hand?"* → a few
- *"Who writes 100% using an agent like Claude Code?"* → a few
- *"Who's somewhere in between?"* → majority (*"like 50% solved"*)
- **Cherny himself: 100%**.
- **Claude Code codebase**:
- *"It leaked, so people know."*
- **TypeScript + React** — chosen because *"very on distribution for the model"* (the model of the time was strong at these technologies).
- *"Pretty simple. There's nothing really complicated."*
- **Model has written 100% of the code since October/November 2025**.
- *"For me today, the model writes 100% of my code. I write somewhere usually a few dozen PRs every day."*
- *"There was a day last week I did like 150 PRs in a day. That was a record."*
- **Acknowledged limits**: *"this is not the case everywhere. There's very big complicated codebases. There's weird languages the model isn't good at yet. Usually the answer is just wait for the next model."* ### Current personal setup (updates)
- **iOS first**: *"most of my work I do from my phone."*
- **Claude app → code tab**: *"a little code tab on the left-hand side, I just have a bunch of sessions going."*
- **5-10 sessions** open, **"a few hundred agents"** active during the day, **"a few thousand"** at night for deeper work.
- **Sub-agents** + **`/loop` slash command** = the new main primitive.
- ***"Loops are the future at this point. If you haven't experimented with it, highly highly recommend it."*** ### Loop: the new primitive
- **Mechanism**: *"You have Claude use cron to schedule a job for some point in the future, and it's a repeat job."*
- **Cadence**: every minute / every 5 minutes / every day — configurable.
- **Cherny's examples**:
- **PR babysitter**: *"fixing CI, auto-rebasing"*
- **CI healthkeeper**: *"if there's a flaky test or whatever, it'll go and fix it"*
- **Twitter feedback clusterer**: *"grabs feedback from Twitter and clusters it for me every 30 minutes"*
- **Routines** = the server-side equivalent of the loop: *"we just launched routines. Even if you close your laptop, it keeps going."*
- **4.7 starts loops spontaneously**: *"I'll tell it 'pull this data query.' And it's like 'Hey, I noticed the data is changing over time. I'll start a loop and I'll give you a report every 30 minutes.' And I'm like 'Great. Can you send it to me over Slack?' And then it uses the Slack MCP to do that."* ### Outlook on teams
- *"There's going to be a lot more generalists than there are today."*
- Not just *"product engineers cross-platform"* (iOS+web+server) but ***cross-disciplinary generalists***: *"engineers that are really good at product engineering, but also really great at design. Or really great at product and data science and engineering."*
- **On the Claude Code team**:
- *"Every single person on our team writes code."*
- List: engineering manager, PM, designers, data scientist, finance person, user researcher.
- *"They're specialist in something, but now also everyone's just coding."* ### SaaS outlook / disruption
- **No SaaS apocalypse**, but a **reshuffling** via Hamilton Helmer's **7 Powers** framework.
- **Powers that become less important**:
- **Switching costs** — *"because you can just use the model and you can port from one thing to a different thing."*
- **Process power** — *"Claude is getting really good at figuring out process. And especially with 4.7, it can just hill climb anything. So if you give it a target and you tell it to iterate until it's done, it will just do it. I think this is the first model like that."*
- **Powers that remain important**:
- **Network effects**
- **Scale economies**
- **Cornered resources**
- **Startup prediction**: *"the number of startups in the next 10 years that are just going to disrupt everything is going to increase like 10x."*
- **Why now**: *"a tiny startup can build a thing that's as valuable as a large company and actually compete head-to-head, because the large company has to evolve their business process, retrain everyone, face internal resistance. But you, starting fresh, can build with AI natively from the ground up."*
- *"It's the best time to build. It's the best time to be a startup. There's so much disruption coming."* ### Pivot analogy — the Gutenberg press
- **1400s Europe before the printing press**: *"essentially 10% of the European population was literate. They knew how to read and write. They were often employed by kings and lords that were not literate."*
- **50 years after the invention**: *"more literature published in Europe than in the thousand years before."*
- **Cost of a book**: ↓ **100×** over the same period.
- **A few centuries later**: *"literacy globally went up to like 70%. Now we can all read and write. You don't need a degree in reading and writing to know how to read and write. Although still there are professional writers."*
- **Analogy applied to 2026+**: *"software will be a thing that is fully democratized, that anyone can do. And it's going to be much faster than 50 years."*
- **Memorable pivot phrase**: *"The best person to write accounting software, I think maybe even today, is not an engineer, it's a really good accountant. Because they know the domain really well, and coding is the easy part. It's knowing the domain that's the hard part."* ### Model vs harness (Q&A)
- *"If you asked me a year ago, the ratio was maybe 50/50. If you asked me 6 months ago, would be 50/50. In 2 years? I don't know dude, we plan in like 1 week out."*
- **The harness becomes less important** as the model improves.
- **Harness evolution**:
- Loops first-class
- Easier to run lots of agents
- Sub-agents (one idea among others)
- *"There's a bunch more stuff that we're cooking."*
- **In 1 year**: *"the model will be much better aligned. And so all the safety mechanisms that we have today around prompt injection and static verification of commands and permission modes, human in the loop, all this kind of stuff is just going to be less important because the model will just do the right thing."* ### Democratization: everyone coding the way everyone knows how to send a text
- *"I think it's going to be a skill like — yeah, like I know how to send a text message."*
- Strong reference to the Gutenberg press model above. ### Internal Anthropic practices
- **No model advantage**: *"internally, we use the same models everyone else does."* Mythos for testing, a lot of Opus 4.7 for dogfooding.
- **Radical practice**:
- *"We use Claude for literally everything."*
- *"Our Claudes are talking all day. As I'm coding, as my Claudes are coding in a loop, they will communicate over Slack to talk to other people's Claudes that are also running in a loop, to figure out unknowns."*
- *"We have no more manually written code anywhere at the company."*
- *"All of the SQL is written by models. Everything is just built by the models."*
- **Anthropic's edge isn't the tech but the process**: *"the place that we're ahead is not the technology — same technology available to us is available to everyone here, because fundamentally we are building a platform. There's actually a far bigger lead in organizational structure and organizational process."* ### Multi-agent / parallelization
- *"On the product side, it really just comes down to prompting. As the model gets better, it just naturally does this."*
- *"It's not on users to figure out how to hold the tools better. If that's the case, it's actually a product design problem and I'm not doing a good job."* ### Local vs cloud, computer use, MCP
- Local vs cloud: *"doesn't matter. By a couple years from now, the model is just going to be doing all the code. It's going to be starting the agents. It's going to be building the environments. If it decides 'actually I'll use local models to do this,' that's what it'll do. These I don't think these will be decisions that we are making as engineers anymore."*
- Knowledge work: *"largely, it's there already with Salesforce and Docs. For us, it's always just the simplest answer. It's MCP."*
- Computer use: *"I think currently, Anthropic is pretty far ahead on computer use. It's quite good. It's very slow, but it does it quite well now, especially with 4.7."*
- *"All this stuff just doesn't matter that much. It could be MCPs, APIs, just some sort of programmatic access — to the model, it's just tokens."* ### Upcoming products
- **Claude Design**: *"It's pretty good today. It's going to get a lot better."*
- **Claude Code**: *"There's also a few things that we're cooking up for Claude Code that are going to be landing over the coming weeks."*
- **Loop, batch, massive agent parallelism**: *"that's going to get better."*
- **Computer use**. ### Connection to the watch dossier
- **Fourth Cherny fiche** in the dossier, after:
- **cherny-yc-lightcone-claude-code-origin-story-2026-02** (YC Lightcone genesis)
- **cherny-claude-code-10-tips-team-x-2026-02-01** (10 tips on X)
- **nunez-cherny-claude-code-workflow-venturebeat-2026-01-05** (VentureBeat workflow)
- **wu-cherny-use-claude-code-builders-every-2025-10-29** (Wu/Cherny Every)
- Plus the fiche **anthropic-claude-code-quality-postmortem-2026-04-23**, of which Cherny is one of the implicit authors.
- **Specific contribution of this fiche** vs. earlier ones:
- **Exclusive iOS setup** = new (vs. the CLI/desktop setup in earlier fiches).
- **`/loop` + Routines** = a new agentic architecture primitive presented publicly.
- **"Anthropic Labs incubator + Mike Krieger round 2" account** = new organizational detail.
- **Opus 4 inflection, May 2025** = precise dating of the takeoff.
- **"100% code generated since October/November 2025"** = personal dating.
- **Gutenberg analogy** + **"the best accountant writes the best accounting software"** = memorable pivot phrases.
- **"7 Powers" Helmer reordering** = a structured SaaS analysis.
- **Sequoia / Lauren Reader** = new venue, investor audience.
- **Major convergence**:
- **`/loop` cron agents** = a radical practical application of the **Ralph Loop** (Trivedy 2026-03-10), Every's *Compound Engineering* (Shipper/Klaassen 2025-12-11), and *Compounding Teams* (Schillace 2025-09-28).
- **"Claudes talking to Claudes over Slack"** = a practical realization of Levie's predictions in *Building for Trillions of Agents* (2026-03-07) and the agent-native infra advocated by Karpathy (2026-04-29).
- **"Coding is solved" + 100% code generated + 150 PRs/day** aligns with **Curran/Intercom's 3× R&D productivity** (2026-04-16, 93.6% agent-driven PRs), **Stripe Minions** (2026-02-09 and 2026-02-19), **StrongDM Software Factory** (2026-02-06).
- **Gutenberg-style democratization** = the same thesis as Karpathy (2026-04-29) on *neural computers* and Andreessen on redefining the programmer (2026-02). Also consistent with the "everyone can code" project championed by Wescale (2026-05-03) and Habert PROJ-AI (2026-05-05).
- **"7 Powers" and SaaS reordering** = sets out a **corporate strategy** framework that is rare in the 2026 corpus, complementary to Sun NYT's *Permanent Underclass* (2026-04-30) on the economic side and Pawlowski's *Tension Map* (2026-03-30) on the market-research side.
- **"The harness becomes less important as the model gets better"** = a direct nuance to the *Harness Engineering* trend (Trivedy 2026-03-10, Osmani 2026-04-19, Böckeler 2026-04-02). Cherny anticipates the progressive absorption of the harness into the aligned model.
- **"Best accountant writes the best accounting software"** = a corollary of the *long tail* of business needs that the Wescale fiche (2026-05-03, *"long-standing needs that were too costly can finally be addressed"*) and Soto's *Developer Taste* (2026-04) anticipated.
- **Limits to flag**:
- **Deliberate techno-centric optimism** — Cherny is the creator of Claude Code, an obvious evangelist bias on *"coding is solved"*.
- **No external figures** — he relies on his own practice and Anthropic's. To be compared with Curran/Intercom's rigorous figures (3× R&D, 93.6% agent-driven PRs).
- **Sequoia format**: no adversarial questioning, a convivial atmosphere, no pushback on *jagged intelligence* (Karpathy 2026-04-29) or on the *permanent underclass* (Sun NYT 2026-04-30).
- **"Coding is solved"**: a provocative statement that deserves nuancing by Karpathy's *"Opus 4.7 will simultaneously refactor a 100,000 line codebase and tell me to walk to a car wash 50 meters away"* (2026-04-29) — surface-level coding is indeed automatable, but *systemic judgment* remains a hard domain.
- **To draw on for**: an 18-month Claude Code retrospective presentation (narrative + dating); a startup *"best time to build"* pitch for the executive committee; a *"loops as the future"* presentation for engineering teams; a course/talk on *"software democratization via the Gutenberg analogy"*; a debate on the position of the *harness* in 2026 doctrine.

## RésuméDe400mots

Boris Cherny, creator of Claude Code at Anthropic, is interviewed at a Sequoia event by Lauren Reader. His central thesis-statement: ***"coding is solved"***. He himself hasn't written a line of code in 2026 — the model has written **100%** of his code since October 2025, *"a few dozen PRs/day, 150 PRs in a single day record"*.

Cherny recounts the **genesis of Claude Code** as a deliberately pre-PMF story. He joins **Anthropic Labs** (internal incubator) in late 2024, with the mission of exploring the *"product overhang"* — *"the model can do all the stuff that no product has yet captured."* At the time, state-of-the-art coding meant *type ahead* (Sonnet 3.5). The bet: *"have the agent write all of the code."* Six months where *"it just really didn't work. I used it for maybe 10% of my code."* First release: *"it was not a hit."* **Inflection point: Opus 4 in May 2025**, then 4.5, 4.6, 4.7 — *"it just kind of keeps inflecting."* The team's round 2 is now led by **Mike Krieger** (Anthropic CPO, ex-Instagram).

**Current personal setup**: *"most of my work I do from my phone"* (iOS exclusively), 5-10 sessions, *"a few hundred agents going, a few thousand at night."* New primitive: **`/loop`** — Claude uses cron to schedule recurring jobs (every minute, 5 minutes, day). Examples: PR babysitter (fixes CI, auto-rebases), CI healthkeeper (fixes flaky tests), Twitter clusterer (groups feedback every 30 min). **Routines** = the server-side equivalent, running with the laptop closed. *"Loops are the future."*

**SaaS outlook**: no apocalypse, but a reshuffling via Hamilton Helmer's **7 Powers** framework. *Switching costs* and *process power* become **less important** (the model hill-climbs processes with 4.7); *network effects*, *scale economies*, *cornered resources* remain **unchanged**. Prediction: ***"the number of startups disrupting in the next 10 years will increase 10×."*** Best time to build.

**Pivot analogy**: the **Gutenberg press**. 1400s Europe: 10% literacy, scribes employed by illiterate kings. Fifty years later: more literature published than in the previous thousand years, books 100× cheaper. A few centuries later: 70% literacy. *"Software will be similarly democratized, but faster than 50 years."* Pivot phrase: *"The best person to write accounting software is not an engineer, it's a really good accountant."*

**Anthropic practice**: *"We have no more manually written code anywhere at the company. Our Claudes are talking all day over Slack to other people's Claudes."* Anthropic's edge isn't technological (same models as everyone else), but **organizational**. As the model becomes better aligned, the **harness becomes less important** — prompt injection, permission modes, human-in-the-loop: *"all this kind of stuff is just going to be less important."* Upcoming products: Claude Design, loops/batch first-class, computer use.
