We launched in February 2026 (announced here), and are already powering pages that generate hundreds of thousands of dollars in pipeline + featured on CNBC.
⚡ Recognized names that turn heads: We've earned the trust of customers like Cognition, Glean, Langchain, Tandem, 11x, + more we don't publicly reference. (Our gong has been put to great use!)
About Flint
Flint is the agentic platform that ships pages from your brand and ad campaigns. AI doesn't replace marketers. It removes the work that should never have been theirs: building a one-off landing page for every keyword, every campaign change, every A/B test, then waiting on design and engineering to do it. Today we deliver on-brand pages on your own domain in minutes, with no rebuilds and no engineers. We're backed by Accel, Sheryl Sandberg (former Meta COO)'s venture fund SBVP, and Neo.
The vision
Sandberg instantly understood Flint's vision. "I was sharing how it took (me) five teams three months to build one A/B test just to increase conversion by 10% on our Google ad," Lim said. "And then she stopped me, [and] said, 'Michelle, it was 140 people at Meta who had to do this'." — TechCrunchImagine a website that builds new pages, tests creative, and optimizes performance in response to real-world signals: competitive shifts, user behavior, trending search queries, the way an autonomous vehicle responds to road conditions and traffic. The marketer still owns the work that compounds and the work that requires taste: strategy, audience, creative direction, brand judgment. Flint takes the manual production off their plate so they get those hours back.
The team
"One of the most talent-dense AI startups... each member of the early Flint team has a track record, and as a team, they perform like athletes. Amazing to watch." - Dan Levine, AccelFlint is led by co-founders Michelle Lim, Engineer #1 turned Head of Growth and Product at Warp, and Max Levenson, engineering leadership at autonomous vehicle startup Nuro, then Engineer #2 at Vooma (YCS23).
Every single member of the Flint team has been a founding engineer / founder. Early stage best practices are in our team's DNA. Because of that, our team knows how to catalyze hockey stick growth, but just as critically, how to navigate it sustainably to create $XB valued companies. After all, we've done it before. We are alums of Netflix, Scale, and Shepherd (YC W21), and work together in-person out of historic Jackson Square.

The role
Flint runs background agents that make changes to real codebases and serves AI-generated pages at scale. That creates an infra problem most companies don't have: many agents editing code in parallel, and you have to coordinate, merge, and ship their work without it turning into chaos.
You'll own the systems that power all of it: cloud architecture, CI/CD, deployments, observability, and security. It's a 0-to-1 role: you'll inherit a scrappy setup and make it production-grade.
Recent work in this role: synchronizing and merging the git output of parallel background agents, building observability for agentic workloads, and hardening deployment pipelines.
What you'll own
The concurrency and coordination problems of running many background agents in parallel, the core hard problem of this role.
Cloud infrastructure end-to-end: architecture, provisioning, CI/CD, deployments.
Cutting latency and cost as we scale, without trading off reliability.
Observability and incident response, so we know when things break before users do.
Security across the stack and deployment pipelines.
Making it easy for product engineers to deploy confidently and debug fast.
You're a fit if
You've scaled a product through real user growth and know what breaks, and when.
You're strong with cloud (AWS or GCP), containers (Docker/Kubernetes), and IaC (Terraform or Pulumi).
You think in systems, performance, reliability, and cost trade-offs come naturally.
You can drop into infra you didn't build and make it better without a runbook.
Bonus
You've been through a startup growth phase.
Security depth: SOC 2, threat modeling, or pen testing.
You've built self-service tooling that product engineers actually used.
