tl;dr: Why choose Flint?

We're winning quickly: Backed by Accel, by the same partner who led the first round for Scale, Vercel, and Sentry, plus Sheryl Sandberg's fund SBVP and Neo. 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'." - 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:

Executive support: Own the CEO's calendar, inbox triage, and meeting prep. Book travel and manage logistics. Prep briefs for investor meetings, customer calls, and external events.
Sales operations support: Run sales follow-up: draft, send, and track responses on open meetings. Maintain and improve our AI-assisted follow-up workflow.
Office management: Run the office move once the new lease is signed. Coordinate interior design, vendors, build-out, Zoom room setup. Day-to-day: supplies, snacks, mail, repairs, cleaning vendor. Manage lease relationship and renewals.
Finance ops: Expense management: collect receipts, code transactions, reconcile against budget. Vendor management: contracts, invoices, payments, renewal tracking. Bookkeeping support: liaise with accountant, prep documents for close, run AP. Software subscription audit and license management.
IT and onboarding: New hire setup: laptops, accounts, software access, Slack, email, calendar, GitHub. First-day experience: welcome kit, intro schedule, paperwork. Off-boarding: account de-provisioning, equipment retrieval, final paperwork. Maintain the IT asset inventory. You can call an IT contractor for troubleshooting.
Recruiting operations: Run sourcing in Ashby: build searches, manage candidate pipelines, keep stages clean, surface promising profiles to the CEO and hiring managers. Write and send candidate outreach, track replies, follow up. Coordinate and run work trials: scope the trial with the hiring manager, send the brief, manage logistics during the trial, collect feedback, debrief. Schedule interviews end-to-end. Manage candidate communication and experience. Offer logistics: backgrounds, references, paperwork, start-date coordination. Ashby hygiene and pipeline reporting: weekly snapshot of where every candidate sits. Maintain the careers page and basic employer-brand surface area.
Events: Own day-of execution for in-person events (partner events, founder dinners, member sessions). Vendor sourcing: venues, catering, AV, swag. Guest list management, RSVPs, communications.
AI workflows and SOPs: Build and maintain internal automations in Claude and Relay. Write SOPs for recurring processes: onboarding, expense flow, event runbooks, sales follow-up. Keep the sales follow-up AI prompt current as tone shifts and the team grows.

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
