About Tonic

Intelligence for music learning. Tonic Notes records the music lesson and turns it into a summary, a practice plan built around the student, and audio clips of every passage worked on. It's the only music-first AI notetaker: fluent in playing, not just speech. Because the most important moments cannot be captured in words.

The role

You'll work directly with the founding team, with real budget authority and an owned audience most seed-stage companies would trade for: a community of musicians, a network of teacher-leaders, and a product people share because it helps them learn the thing they love.

Find what works

• Launch 0-to-1 experiments across community, influencer, paid, and referral channels
• Read early signal honestly: kill fast, double down faster

Build the engine

• Connect channels into loops that feed each other
• Shape campaign narratives with product, design, and artist collaborators; own delivery for multi-channel launches

Know the numbers

• Own CAC, conversion, and retention per channel; run A/B tests where they settle arguments
• Decide from data, and be the person the room trusts to say what it means

Make it repeatable

• Turn validated experiments into playbooks; direct contractors and the growth team as channels mature
• Recognize when a channel graduates from experiment to system, and drive it there

The first six months

• New acquisition channels validated beyond the ones we've proven
• At least one channel scaled with healthy economics
• Early cross-channel loops connecting what works
• Operating with autonomy: prioritizing experiments, allocating budget, tracking performance

Who thrives here

• 5+ years in growth or user acquisition with results you can point to and explain
• Fluent in metrics: designs experiments, reads data without a translator, makes fast calls
• Uses modern AI tools as a force multiplier across everything: research, creative, analysis, ops
• Comfortable across the stack we run (Amplitude, Meta Ads, spreadsheets, and whatever the experiment needs)
• Creative and analytical in the same day: the story and the spreadsheet are one job here
• Bonus: experience in music, creator tools, or consumer social. If you've ever taken lessons, you'll feel this product faster.
