Codebase knowledge graph shipped as a skill for Claude Code, Cursor, Codex and Gemini CLI. YC S26, London. graphify.com
A hundred thousand stars in seventeen weeks is among the fastest ever. We tried to prove it was bought. It isn't.
Corroborating: 185 contributors, 2,407 issues in four months with real reproductions (version numbers, OS, internal function names), and an unprompted third-party ecosystem — a .NET port, a Rootly importer, HKUST academic use, a Rust reimplementation. Star-farmed repos are hollow. This one isn't.
Residual doubt: downloads-per-star is 17, against 136 for llama-index and 2,036 for uv. Confounded by age and by this being a once-per-developer install rather than a CI dependency, but it's the one metric that doesn't corroborate a 101k audience. The honest read is a large shallow audience over a real, smaller, active user base.
Not Hacker News — every Graphify post there got single digits. A rival founder's own Ask HN records the actual origin: "Graphify launched off the back of a Karpathy tweet — 12k stars in 48 hours." One tweet from the right person, then compounding.
| Raised | $500,000 pre-seed, 28 May 2026. Y Combinator is the only investor. That's the standard YC deal, not a priced round. No Form D on file, no outside capital. |
|---|---|
| Valuation | Not disclosed. Harmonic's $2M is its own model, not a mark. |
| Team | YC says 2, LinkedIn 3, Harmonic 4, GitHub org 0 public members. One engineer. Safi writes 944 of ~1,100 commits; the next contributor has 27. The other staff read as operations and business development. |
| Founder | Safi Shamsi. MSc Data Science, Birmingham, finished Oct 2025. One engineering job before this — AI Engineer at Valent, five months. Built the repo nights and weekends while employed there. No elite org, no prior exit, largest previous repo 32 stars. |
| Revenue | None. No pricing page, no cloud tier. Enterprise is a waitlist marked "early access." YC lists Rootly, Geotab, Tweddle Group and Superagent as customers — unverified, though Rootly did ship an importer. |
The 100k announcement carried two boasts. "5th YC-backed OSS project to hit 100k" — it's the 7th, behind build-your-own-x, opencode, ollama, firecrawl, browser-use and supabase. "First Indian developer to ship a 100k-star repo" — false: TheAlgorithms/Python (223k, Anup Kumar Panwar), TensorFlow (Rajat Monga), PyTorch (Soumith Chintala) all predate it by a decade. The founder is also London-based, Indian by origin.
Separately, the README's headline "71.5x fewer tokens" comes from a hand-picked 52-file corpus; their own honest number is 5.4x. Smaller housekeeping: the Discord invite in the README is expired, pyproject declares MIT while the repo declares Apache-2.0, and after 200 releases it has never cut 1.0.
The traction is real and we could not break it — that's the finding, and it's worth something. But Daxos would be underwriting a solo founder with five months of professional experience, no revenue, no moat under a permissive licence, in a category where the two closest analogues went to zero, against a platform owner one quarter of engineering away from copying it.
The practical problem is price. At $500K post-YC this would be interesting. After 100k stars and an S26 demo day, the next round clears well above where a $100–500K check buys meaningful ownership. Track it, take the meeting, don't chase the round. The thing to watch is whether a paid SKU ships before the star curve flattens.
