AI coding assistants are taking the tech world by storm, with a massive chunk of developers now using these tools according to GitHub's recent survey. Jared Friedman from Y Combinator even mentioned that a whopping quarter of the W25 startup batch at YC have AI generating 95% of their code.
Seeing this trend, venture capitalists are jumping at the chance to invest in startups creating AI-powered programming tools. Graphite, one of these startups, just announced a hefty $52 million Series B funding round. The round was led by Accel, with contributions from Anthropic’s Anthology Fund, Menlo Ventures, Shopify Ventures, Figma Ventures, Andreessen Horowitz, and The General Partnership.
Graphite was founded back in 2020 by Tomas Reimers, Greg Foster, and Merrill Lutsky. Reimers used to be a software developer at Facebook, Foster worked as an engineer at Airbnb and Google, and Lutsky started Posmetrics, a customer feedback company.
Originally, Graphite focused on mobile development tools, but soon shifted gears to code review. Nowadays, their platform uses AI, specifically models from Anthropic and OpenAI, to spot errors and potential issues in code.
Lutsky explained to TechCrunch that Graphite started as an internal tool to streamline their own code review process. After sharing it with a few ex-Meta engineers, word spread fast, and the demand for Graphite became too strong to ignore.
Besides reviewing code, Graphite can also suggest changes based on developer comments, summarize code, and come up with fixes for code problems. Next up, Graphite is launching Diamond, an AI tool that automatically catches coding bugs and errors, as a separate product.

Plus, there are niche players like CodeRabbit and DeepCode focusing on AI-powered code review. Even OpenAI has updated its macOS ChatGPT app to edit code directly in popular development tools, and Anthropic, one of Graphite's investors, has its own assistive programming tool.
Despite the competition, Graphite has found its own space by addressing concerns about the reliability of AI in coding. They let customers set up unique patterns and filters for sensitive info to keep their codebases secure.
Lutsky shared that Graphite's revenue skyrocketed 20x in 2024, and they're now serving tens of thousands of engineers at over 500 companies, including big names like Shopify, Snowflake, Figma, and Perplexity. This new funding gives them plenty of runway, a solid path to profitability, and the means to really push growth and AI development.
To sweeten the deal, Graphite made its core code review tool free for teams of any size. Before, only teams of 10 or fewer could use it for free.
With this latest round, Graphite has now raised about $81 million in total. The 30-person company plans to use the new funds to develop their products further and expand their team in NYC.

Graphite is cool, but honestly, it feels a bit overhyped. It's great for quick code reviews, but sometimes it misses the mark on complex issues. Still, it's a solid tool for startups looking to streamline their process. Maybe it'll get better with time, who knows?

Graphiteは便利だけど、ちょっと過大評価されている気がする。複雑な問題には対応しきれないことがあるけど、スタートアップには便利なツールだね。もっと良くなるといいな。

그래파이트는 정말 유용하지만, 솔직히 과대평가된 느낌이에요. 복잡한 문제에는 좀 약한데, 스타트업에는 꽤 괜찮은 도구네요. 시간이 지나면 더 나아질까요?

Graphite é legal, mas acho que está um pouco superestimado. É ótimo para revisões rápidas de código, mas às vezes falha em questões complexas. Ainda assim, é uma ferramenta sólida para startups. Talvez melhore com o tempo, quem sabe?

Graphite está bien, pero creo que está un poco sobrevalorado. Es genial para revisiones rápidas de código, pero a veces falla en problemas complejos. Aún así, es una herramienta sólida para startups. Quizás mejore con el tiempo, ¿quién sabe?

Graphite's AI-driven code review is a lifesaver for devs! It's super helpful for catching bugs early, but sometimes it feels a bit too strict. Still, it's a game-changer, especially with Anthropic backing it. Just wish it was a bit more flexible.
