Artificial Intelligence Coding Assistant is becoming very popular. The vast majority Respondents in the latest Github poll said they adopted some form of AI tools. Y-combination partner Jared Friedman Recent claims One quarter of YC’s W25 startup batches have 95% of the code base generated by AI.
Feeling the opportunity, venture capitalists are eager to return to startups that develop AI-driven auxiliary programming tools. One of these startups, graphiteIt has raised $52 million in Accel-led Series B competition to participate Human Selection Fund With Menlo Ventures, Shopify Ventures, Figma Ventures, Andreessen Horowitz and general partnerships.
Tomas Reimers, Greg Foster and Merrill Lutsky founded Graphite in 2020. Reimers is a former Facebook software developer, while Foster is an engineer at Airbnb and Google. Lutsky previously founded Posmetrics, a customer feedback solution company.
Graphite started life as a mobile development tool company, but soon after opening the store, it involved code review. Today, Graphite’s platform provides feedback on code, leveraging AI (particularly human-made and OpenAI models) to mark errors and possible supervision.
“Graphite was originally used as an internal tool to solve our own pain,” Lutsky told TechCrunch. “We shared our construction with some former Meta engineers, and they quickly shared it more widely, and the demand for graphite quickly became too large to ignore.”
Graphite also recommends commenting on the code base from developers, summarizing code changes to the code, and generating possible fixes for code failures. For the next behavior of the startup, Graphite will rotate Diamond, an AI tool designed to automatically capture encoding errors and errors as standalone products.

There is a lot of competition in the AI coding assistant space. Exceed Github Sub-Blogger and well-funded efforts such as cursor manufacturers Anyone,,,,, Poolside,,,,, Enhanced,,,,, magicand codestart-up company coderabbit and Deep coding Both focus specifically on AI-driven code review applications. Recently Openai Updated the Macos Chatgpt application Edit code directly in popular application development tools, Anthropic (one of Graphite’s financial backers) has Auxiliary programming tools My own.
However, Graphite has managed to create a niche for itself Reliability risk Related to AI-driven auxiliary coding tools. Unlike some tools on the market, Graphite allows customers to define patterns unique to the code base and set filters for sensitive information that may compromise the security of the code base.
“Revenues grew 20 times in 2024 and we have served thousands of engineers in over 500 companies, including Shopify, Snowflake, Figma and Clelxity,” Lutsky said. “Combined with our revenue growth, this new funding provides us with a number of years of runways, clear paths to profitability, and resources actively investing in growth and AI.”
To make its platform more attractive, Graphite makes its core code review available for free for teams of all sizes. Previously, groups with only 10 people or fewer had access to the company’s tools for free.
With the latest round of funding, Graphite has raised about $81 million in venture capital so far. The 30-member startup said the latest batch will be used for product development and to develop its New York City-based team.
