Frequently asked questions
Which case study should I read first?
Start with your industry, then pick the type of work closest to your bottleneck: Creators for reach and trust, Paid ads for volume at a known cost, Product if users sign up but don't stick, and All three if you want one team on everything.
Do you have work in my industry?
Probably. There are four case studies in each of 16 industries, from AI agents, developer tools and fintech to dating, health, education, creator tools, SMB software and New York startups. If yours isn't listed, the closest industry usually shares the same buyer and channels.
What does a program cost?
Engagements start with a 90-day growth sprint, from $10,000 a month for a dedicated human growth lead plus agents. Creator fees and media are paid at cost on top, and paid ads programs need at least $15,000 a month in media to test properly.
How fast do results show?
The first creator post goes live 2–3 weeks after kickoff, and each new ad concept gets $500–$1,000 or 7 days before a kill or scale call. In product growth, the first experiment is live by week 3 and the first readout comes by week 6.
