Head of Growth Lab
We are looking for a Head of Growth Lab to discover, validate, and scale new multi-million dollar business lines within Muse Group's ecosystem. You will lead a small cross-functional team, run fast discovery sprints, and make data-backed kill/scale decisions — operating like a startup founder with access to 1.5M daily users, a massive content library, and the credibility of the world's largest music publisher.
What's in it for you?
- Build new businesses, not optimize old ones. You won't be tweaking conversion funnels. You'll be finding the next $10M product line.
- Speed and autonomy. Small team, minimal bureaucracy, quarterly verdicts. Ship experiments in weeks, not months.
- Massive distribution advantage. Leverage Ultimate Guitar, MuseScore, Hal Leonard, MuseHub, and audio.com — millions of musicians already in the ecosystem.
We are actively integrating AI and automation into all areas of the business and expect candidates with mindset focused on improving efficiency and deliver a better user experience.
Key responsibilities
Required experience
- Demonstrated experience launching new products or business lines (0→1) — not just growing existing onesStrong quantitative skills: back-of-envelope revenue modeling, unit economics, TAM/SAM sizing — in real time, not in a spreadsheet after a week
- Track record of making kill/scale decisions based on data within tight timelines
- Experience leading cross-functional teams in fast-paced, low-bureaucracy environments
- Comfort with deep ambiguity — no one will hand you a roadmap
- Fluent English
