Sheryl Sandberg-backed Flint wants to use artificial intelligence to autonomously create and update websites

Sometimes, you can only discover errors when you’ve been part of the process for a while. This was the case for Michelle Lim during her candidacy WarpThe company’s marketing growth efforts over the past year realized that the company was not updating its website fast enough.

She noticed that potential customers were asking ChatGPT and other AI bots all kinds of questions about Warp’s offerings, but the information they were looking for, like how the product compared to a newer competitor, wasn’t available on the startup’s website. Lim felt that this content gap would become more important when next-generation AI agents began actively crawling the Internet to gather intelligence for users.

It was clear that Warp needed to add more content, but creating and uploading each additional web page was a time-consuming task involving a design agency and many people across different departments.

“Marketers can’t afford to wait a month for the design and development teams to build the page,” she told TechCrunch. “With AI engines, you need to produce content much faster than before to meet consumer demand.”

Lim, who had long planned to launch a startup, realized that this quickly became a problem that needed to be solved. So, in March, I co-founded it Flintan AI-powered platform that lets you set up websites that update themselves. She is joined in the effort by Max Levinson, an engineer who previously led the simulation and infrastructure teams for autonomous vehicle startup Nuro.

On Tuesday, Flint came out of stealth mode with $5 million in seed funding. The investment was led by Accel, and saw participation from Sheryl Sandberg Fund, Sandberg Bernthal Venture Partners, and existing backer Neo.

Flint’s goal is to create websites that constantly improve themselves, conduct their own A/B tests, and learn dynamically from both visitors and market trends, such as sudden interest in a particular keyword. Flint also aims to create personalized pages for each visitor, much like how Amazon displays personalized product recommendations for you.

However, Flint technology isn’t ready to do all that yet. “For now, users still have to tell us what they want to build,” Lim said.

In its current form, once parameters are set, Flint can automatically generate web page design and layout, interactive elements (such as tables and buttons), as well as offer form tracking and ad optimization. Lim claims the platform can do all of this in “about a day,” though she didn’t provide any further details.

“At this point, customers are coming up with their own version,” Lim said. She added that although Flint’s content writing functionality is still about a year away, future versions will give customers the option to have AI write the text.

Even without that, Lim claims that setting up a page with all the necessary components in one day is already a huge time saver for its clients.

Flint says it doesn’t design websites or “live code” for anything. For existing websites, its technology analyzes the look and feel to create and publish fully coded, design-compliant web pages.

The startup already works with clients like Cognition, Modal, and Graphite, for whom it has created live pages. You can see Surf here, Modal websiteand This is what graphite looks like.

Flint’s ambition is to help marketers at fast-growing startups and Fortune 500 companies increase their website exposure and content creation.

The focus on selling to CMOs is what made Lim so excited to have Sheryl Sandberg on board as an investor. “I like to think of her as someone who influenced the way online monetization has been done over the past decade,” Lim said.

According to Lim, Sandberg immediately understood Flint’s vision. “I was showing her this group, and I was sharing how, in my personal experience, it took five teams three months to create just one A/B test to increase conversion by 10% on our Google ad,” Lim said. “Then she stopped me and said, ‘Michelle, 140 people in Meta had to do this.’
