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.
Key responsibilities
- Find and size opportunities. Scan the intersection of audience × content × business model across Muse Group's portfolio. Build top-down revenue estimates before committing resources. Maintain a prioritized pipeline of bets.
- Run discovery sprints. Design and execute 2–3 week hypothesis-driven experiments: landing pages, MVPs, content tests. Drive acquisition from existing products and measure real willingness to pay.
- Make kill/iterate/scale decisions. Present quarterly findings with clear data and a recommendation. Every bet gets a verdict.
- Own the business case. Build and maintain unit economics, revenue models, and P&L projections for each bet. Translate early signals into scalable business plans.
- Lead a cross-functional team. Manage a small, fast squad (designer, analyst, frontend developer) plus shared backend, CRM, and research resources. Set the pace and remove blockers.
- Spot external tailwinds. Track regulatory changes, funding programs, market shifts, and new distribution channels. Move fast when an opportunity window opens.
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
