Why take the bet
We're early-stage, so the risk is real: timelines move, and equity is worth what the company becomes, not what it's valued at today.
Here's why we think it's worth it. We're two ex-Spotify engineers who've shipped and scaled software used by millions, funded, and building with real customers every week. There's also a shift worth betting on. What they can't do is untangle a vague problem, design a data model that holds up under real usage, or debug something failing in a way nobody expected. After a few years in the job, the thing that sets you apart isn't how fast you type, it's your judgment, and that's exactly what this role leans on.
Competitor moves, deal objections, buyer feedback, and coaching gaps are trapped across call recordings, CRM notes, documents, and Slack threads.
Show sales leaders where deals are advancing or stalling, while helping BDRs research territories and identify the right accounts to bring into pipeline




Let reps practise against voice-based AI buyers grounded in real deals, objections, and battlecard content
