About Flint
Flint is the first self-improving system for performance marketing. We connect to brands' ad accounts and optimize them by instantly creating pages for each ad group and running a learning loop that continually improves conversions. We just signed a Fortune 10 customer, and within 48 hours their customer acquisition cost decreased by 50%. We're backed by Accel, SBVP, the venture fund of former Meta COO Sheryl Sandberg, and Neo.
Sandberg instantly understood Flint's vision. "I was sharing how it took five teams three months to build one A/B test just to increase conversion by 10% on our Google ad," Flint CEO Michelle Lim said. "And then she stopped me, [and] said, 'Michelle, it was 140 people at Meta who had to do this'." — TechCrunch
We envision a future where every business will have an autonomous digital marketer that responds to real-world signals, like competitive shifts, user behavior, and trending search queries, the way an autonomous vehicle responds to road conditions and traffic.
About the team
Flint is led by co-founders Michelle Lim, who went from Engineer #1 to Head of Growth and Product at Warp, and Max Levenson, an engineering leader at autonomous vehicle startup Nuro and then Engineer #2 at Vooma (YC S23). Most of our team has founded a company or been a founding engineer, so you’ll be working with people who’ve built from zero before.
About the role
As a Performance Marketing Strategist, you’re the paid acquisition expert behind every account Flint runs. We work with brands that spend millions across Google and Meta, and you’re the one who makes that spend pay off. You run the accounts hands-on, from structure and targeting to bidding, budgets, and creative testing, and for once the landing page is yours too. You’ll see how paid acquisition plays out across many different brands, and you’ll know what’s working within days instead of months.
Everything you know about performance marketing goes into Flint’s ads agent, so you get to build the frontier AI for your craft. Over time, the way you run accounts becomes the way Flint runs them for every brand we work with.
