We're winning quickly.

• 
  
• We’re backed by Accel, by the same partner who led the series A for Scale, Vercel, and Sentry. We launched out of stealth 2 months ago (TechCrunch), and are already powering pages that generate hundreds of thousands of dollars in pipeline. Also recently featured on CNBC.
  

We're drowning in demand.

• 
  
• Flint has thousands of companies on our waitlist with many coming inbound every day. The market has spoken. We're growing our team so we can stop turning away customers.
  

Recognized names that turn heads.

• 
  
• We've earned the trust of customers like Cognition, Reducto, Graphite, Tandem, and more.
  

Flint is defining the next generation of websites: ones that can constantly build and optimize themselves based on visitor behavior and market changes. Today, we deliver on-brand landing pages on your domain fast, without any rebuilds or engineers. We are backed by Accel, Sheryl Sandberg (former Meta COO)'s venture fund SBVP, and Neo.

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 world where your website launches new pages, tests creative, and optimizes performance entirely autonomously. Just as autonomous vehicles respond to real-world inputs like road conditions and traffic patterns, Flint-powered websites respond to external signals such as competitive shifts, user behavior, and trending search queries.

"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). Our founding designer Leona Hudelson was previously head of Growth Design at Netflix in charge of optimizing 1B+ visits to .

Companies have used Flint to hit goals like…

• 
  
• Ranking #1 on AI answer engines like ChatGPT, Perplexity and Google AI Overview
  
• Driving 50% higher ad conversion rates on Google Ads months ahead of schedule
  
• Generating 7 figures of ARR
  

The first version of Flint's autonomous website platform produces on-brand landing pages from content briefs and prompts in minutes. Flint ingests a company's existing design system (components, brand guidelines, and visual tokens), then generates fully-coded landing pages that live on the customer's top-level domain, on a subfolder at URLs like /campaign-name

We're looking for a founding marketing lead to build Flint's marketing engine and establish Flint as the de facto brand for marketing websites.

As Founding Marketing Lead, you'll be THE marketer at a marketing company. Your opinions will deeply shape the product. This is a rare opportunity to shape how marketers think about AI, websites, and GTM while building Flint's growth engine from the ground up.

Flint has already run a successful product launch such as the out-of-stealth launch, been covered by Techcrunch, CNBC, and Business Insider, hosted in-person events like Growth Craft, and is crushing it on founder-led socials. Your job is to build on this momentum with the CEO and turn Flint into the biggest brand in the space.

• 
  
• Lead product launches: Own the launch for new features and releases, from messaging to rollout.
  
• Define brand and positioning: Own Flint's messaging frameworks, positioning docs, and brand voice as we create the autonomous website category.
  
• Lead content that teaches: Create use-case playbooks, example prompts, tutorials, case studies, and demos that help marketers get value from Flint. Drive self‑serve activation and early‑user success.
  
• Build and scale partnerships: Partner with design agencies, develop affiliate programs, and build integrations with GTM tools like Clay.
  
• Own sales enablement: Create the materials, decks, case studies, and resources that help prospects succeed with Flint
  
• Be the voice of Flint: Edit and publish LinkedIn content weekly and lead newsletters and events.
  
• Build and maintain our marketing website and docs: Ensure Flint's web presence is as sharp and innovative as our product.
  
• Surface product feedback: Work cross‑functionally with Product and Engineering to relay customer friction and shape the roadmap.
  
• Build the marketing team: As Flint scales, help hire and manage marketers.
  

• 
  
• Strong writing and storytelling chops: you can distill complex ideas into crisp, compelling messaging.
  
• You're the kind of person who would be a power user of Flint, and if you're not yet, you're excited to make it happen.
  
• 4+ YoE in B2B SaaS growth or product marketing with hands‑on execution, ideally at a fast‑paced startup.
  
• Bias for doing, not just strategizing. You ship content, run experiments, and iterate quickly.
  
• Strong content and education skills: you can create tutorials, webinars, and docs that actually help people.
  
• Practical SEO and paid acquisition experience, acquired either directly or adjacent to the function.
  
• Comfortable on camera.
  
• Data‑driven: you can set and report on traffic and conversion.
  
• Bring a founder's mindset to your work: be proactive, resourceful, and comfortable operating without a playbook.
  

• 
  
• Enthusiasm for Claude Code and AI‑native marketing workflows: you believe this is the future and want to be at the forefront.
  
• Comfortable with product tooling and integrations (APIs, Zapier, Clay‑like automations).

• Experience with marketing automation or sales enablement tools (HubSpot, Notion, etc.).
  
• Familiarity with design systems or Webflow workflows.
