What is HeyMark?
Mark is an AI-powered digital marketing agent that replaces agencies. You talk to him, and he does everything. Analyzes your metrics, generates strategy, creates visual content and video, automates DMs, manages ads, publishes and schedules content. All from a chat with an interactive visual canvas.
70+ tools in production. Video generation with 15 models, UGC with AI avatars and voice cloning, competitive scraping, email marketing, direct publishing to Instagram and TikTok, automated ads on Meta and Google, context-aware automated DMs, and a full billing system with credits.
It’s like having a complete marketing team, operated by a single agent.
Who are we looking for?
Someone who wants to build product. Who understands that code is a means, not the end. Who obsesses over every feature they ship solving a real problem for a real user.
We’re not looking for someone who just executes tickets. We want someone who has opinions, who proposes, who understands the business and makes product decisions from the code.
What you’ll do
- Build features end-to-end. From the interface to the API
- Work on Mark’s chat, the canvas, social media integrations, the billing system
- Iterate fast. Ship, measure, improve
- Collaborate directly with the founders on what gets built and why
- Integrate new tools and capabilities into the agent
We’re building the best build-in-public ever. Cameras on every day. Being comfortable on camera is part of the job.
