Join theTeam.
The teams at Coursera, Notion, ClickUp, Handshake, Lemonade, and Mercury run their lifecycle marketing on our agents. We raised $17M to prove that always-on AI — not hand-built campaigns — is how 1-1 personalization gets done at scale. We're 11 people hiring the founding team that owns it: on-site in San Francisco, pay public on every role, working directly with the founders. Every seat is in-person and full-time in San Francisco — there's no remote or hybrid option — and open only to candidates already authorized to work in the U.S.

"Every message a company sends should feel like it was written for exactly one person. We're building the machine that makes that true — and we're excited to build the future with you."
what you actually get
Small team. BIG table.
Eleven people, one room in San Francisco, and a standing rule that wins get celebrated properly. Here's what that actually looks like.
Six values we run on — not poster words.
This is not a place to coast. It's a place to compress a decade of learning into two years, ship things you're slightly afraid of, and watch them run at a scale most engineers never touch. These are the values we hold each other to, every day.
not a family.
>> skills and numbers.
Be passionate. give it all.
act short term.
communication is the key.
not AI first.
You won't maintain software.
You'll raise a workforce.
JustAI is a team of autonomous agents that run lifecycle marketing end to end — and a team of humans who make those agents smarter every week. Whatever you join to do, this is the machine you're building.
Strategy Agent
Uncovers patterns between users who convert and those who don't — predicting rich cohorts, untapped segments, and high-leverage moments. The problems here are pure applied ML at unfair scale.
Creative Agent
Blends brand voice, user insight, and product knowledge into conversion-ready content — millions of on-brand variants, zero copywriter burnout. LLM orchestration with real constraints and real stakes.
Decisioning Agent
Real-time reinforcement learning across channels: identifies winning variants and routes traffic to what performs, turning every send into a self-improving loop. Bandits, in production, at billions of decisions.
Data Agent
Turns billions of events into instant, actionable insight so no one ever waits for an analyst again. The infrastructure under this is the kind of thing infra engineers brag about at parties.
Two seats.
