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'." — TechCrunch

Imagine 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, Accel

Flint 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 product

Companies have used Flint to hit goals like…

• Ranking #1 on AI answer engines like ChatGPT, Perplexity and Google AI Overview

• Lifting ad conversion rates

• Generating hundreds of thousands of dollars in pipeline revenue

The role: Executive Assistant and Office Manager

You own the systems that let the founder and team focus on building and selling. The role spans executive support, office operations, vendor and finance ops, IT setup, recruiting coordination, event production, and the internal AI workflows that hold it all together. You report to the CEO. This is a high-trust, high-autonomy role at a fast-moving early-stage company. You're the person who makes everything else run on time.

The candidate we're looking for does the following:

• Own the CEO's calendar, inbox triage, and meeting prep, and book travel and manage logistics

• Run sales follow-up: draft, send, and track responses on open meetings, and keep our AI-assisted follow-up workflow current

• Prep briefs for investor meetings, customer calls, and external events

• Run the office: supplies, mail, repairs, vendors, the lease, and the office move once the new lease is signed

• Work the front desk. Greet whoever walks in, and keep packages and mail from piling up

• Set the tone of the space. You're the reason the office feels calm on a normal day and handled on a chaotic one. You'll know everyone's name and clock when something's off before they do

• Onboard new hires end to end (laptops, accounts, access, welcome kit) and off-board cleanly

• Keep recruiting moving: schedule interviews, manage candidate experience, run work-trial logistics, keep Ashby clean

• Own day-of execution for in-person events, from venue and catering to guest list and RSVPs

• Build internal automations in Claude and Relay, and write the SOPs so recurring work runs without you

  Basic qualifications:

• 3+ years in executive support, chief of staff, office management, or a similarly broad role at a startup or small high-output team

• You default to writing things down. SOPs, runbooks, and checklists are how you scale yourself

• You're fluent with modern tools: Slack, Notion, Google Workspace, Ashby or an equivalent ATS, expense and AP tools, calendar and travel platforms

• You move fast and finish. You'd rather ship a v1 today than a v3 next week

• You read context well. You know when to ask, when to decide, and when to just handle it

• Strong written communication. You can draft a credible follow-up email, a candidate note, or a vendor brief without hand-holding

• You're in SF or moving here. We work from the office

Preferred qualifications:

• You've used AI tools (Claude, ChatGPT, Relay, Zapier) to automate real work, not just experiment

• You've set up payroll or benefits from scratch, or cleaned up a mess someone left behind

• You've run an office move or a company offsite end to end
