A new wave of website automation has begun with the launch of Flint, an artificial intelligence-driven platform co-founded by Michelle Lim and Max Levenson. The startup, which officially emerged from stealth mode on Tuesday, secured $5 million in seed funding led by Accel, with participation from Sheryl Sandberg’s Sandberg Bernthal Venture Partners and existing backer Neo.
Flint’s innovation stems from Lim’s earlier experience at Warp, where she observed how slow website updates hindered customer engagement, especially as AI bots like ChatGPT became key channels for product discovery. Flint’s platform allows users to create websites that update themselves, continuously optimize their content, and adapt to visitor behavior and emerging market trends.
The tool can generate layouts, interactive features, and ad optimization features in about a day, offering a faster alternative to traditional web development processes that could take weeks. Although Flint’s AI is yet to autonomously generate full textual content, the company says this feature is under development and will be integrated into future updates.
Lim explained that marketers today cannot afford to wait for lengthy design and development cycles, especially in an era when AI engines shape consumer demand in real time. Flint’s system eliminates the need for manual web coding or design, automatically analyzing existing brand aesthetics to build fully coded, on-brand web pages. The startup already counts clients such as Cognition, Modal, and Graphite, for whom it has developed live and dynamic web pages that mirror their original site aesthetics.
Flint’s ambition is to empower marketers—especially those in fast-growing startups and Fortune 500 companies—to enhance visibility, responsiveness, and user engagement. Lim expressed excitement over Sandberg’s involvement, noting that her experience at Meta aligns perfectly with Flint’s mission of streamlining digital content operations.
“Sheryl instantly understood our vision,” Lim said, recalling Sandberg’s observation that what Flint does in a day once required large teams and months of effort. With its new funding, Flint is poised to redefine how companies build and maintain web presence in the AI era
