Flint Raises $5M for Autonomous Websites

updated

In November 2025, San Francisco-based AI startup Flint launched from stealth with $5 million in Seed funding. The round was led by Accel, with participation from Sandberg Bernthal Venture Partners (Sheryl Sandberg’s fund) and Neo.

Founded by CEO Michelle Lim (formerly first engineer at Warp) and CTO Max Levenson (formerly of autonomous vehicle startup Nuro), Flint is building a platform for “autonomous websites” that can build and optimize themselves.

The company’s AI-driven system is designed for growth and marketing teams, enabling them to generate on-brand landing pages, perform A/B tests, and optimize for SEO in real-time without engineering bottlenecks.

The new capital will be used to expand its design and applied AI engineering teams and accelerate the development of its autonomous website technology for its waitlist customers.
