Founding AI Growth Marketer

What we're looking for

We need an experienced B2B growth marketer with a builder's mindset who has hands-on experience running structured growth experiments with real budget accountability — and who can personally build a fleet of AI agents to power those experiments at scale. You should be comfortable creating content end to end (product videos, ad creative, landing pages, campaign copy) and have a track record of driving pipeline, conversions, and CAC efficiency. Bonus points if you've been a founder or worked at an early-stage startup, especially in legal tech or enterprise B2B.

What you'll do

• Build and operate an AI-powered experimentation engine — spin up a fleet of agents (using tools like Claude Code or similar) to generate, launch, and evaluate top-of-funnel experiments across messaging, channels, creative, and acquisition cost at a pace no human-only team could match.
• Own growth end to end — design experiments with clear hypotheses and success criteria across paid (Google, LinkedIn), organic, SEO/AEO, Reddit, lifecycle, and partnerships. Track spend, conversion, leads created, deals created, and map results back to ARR and pipeline.
• Create all content yourself — script, produce, and edit short product videos (90-second turnarounds), ad creative, launch assets, landing pages, and campaign copy targeting technical enterprise buyers (legal, procurement, GTM ops) without relying on agencies.
• Benchmark and research competitors — continuously analyze what other players in the legal tech and contract AI space are doing and use those insights to refine positioning, messaging, and ICP targeting.
• Build your own marketing data stack — pull your own numbers, centralize data from different channels, build dashboards, and report on outcomes (pipeline, signups, CAC efficiency) rather than activity or impressions.
• Partner directly with the founders — sit in on roadmap conversations, bring market signal back, and shape what gets built and how it's positioned. You'll be designing the marketing function from scratch as the first dedicated marketing hire.
