Tech/techno/techwear. CEO @withgraphite - code review for the age of AI.
Today we announced @withgraphite's $52m Series B, led by @Accel with support from @MenloVentures & @AnthropicAI's Anthology fund, @a16z, @thegp, and our customers @shopify & @figma! @Kyle_L_Wiggers from @TechCrunch covered the round!

Developers like extensibility, but making everything configurable creates product debt and offloads the hard decisions onto your users. Great products have an opinion - building for everyone is building for no one.
Congrats to @amasad and the team on $100M ARR! @Replit cooks @withgraphite + 💎
Earlier this month, we crossed $100M in ARR, up from $10M at the end of ’24. But that’s just fraction of the value we’re creating: from enterprise teams like @zillow and @HubSpot shipping faster, to solo builders like @yoheinakajima and @GerrardL_ building and running their…
Stacked PRs are a force multiplier for human<>agent collaboration, and Graphite's MCP gives agents everything they need to start stacking.
Take on bigger tasks with your agents. GT MCP trains your agents to create smaller sequenced PRs, so you can easily follow what changes were made and get more done.
Agents already think in steps. Claude Code plans work with to-do lists. @withgraphite MCP turns those steps into stacked PRs, so you can more easily review the resulting code and understand the agent’s reasoning.
Your agents now stack. GT 🤝 MCP is out, in beta. GT MCP instantly enables your agents to create smaller stacked diffs that are easier to review, so you can better understand what's changed. Set it up here → graphite.dev/docs/gt-mcp#in…
Get instant feedback on your draft PRs — before your reviewers even see them. You can now let Diamond review your draft PRs. Turn it on in your Preferences tab in Graphite.
12th most-used AI devtool and we’re just getting started.

Good code review comments lead to code changes. By this metric, Diamond slightly beats human reviewers (51% vs. 50% comment acceptance rate) and outshines noisy competitors (33-38%).
Our bottleneck is no longer writing code, but reviewing code
Going viral isn’t worth much unless you harness the attention. We turned our 1st time on the front page of HN into 2,000+ developer sign-ups in 36 hours. The key was a viral loop: invite 4 more eng from your team to skip the waitlist. Great launches have a built-in second act.
We liked the name Graphite because it felt right. Pencil, not pen. Iterative, not permanent. Something you build up in layers, not all at once. That’s how good software is built.

Merging PRs from my phone is one of the greatest feelings ever ty @withgraphite
