Mister Raw published three books, including Customer, Traction, and Investors.

Mister Raw works with B2B founders, startups, and company leaders who are serious about building something that scales. With nearly three decades in business, Stefan Avivson has built 15 companies, exited 5, gone bankrupt twice, raised millions in capital, and generated millions in revenue — both for himself and for the founders he works with. The work is not motivational coaching. It is commercial alignment. Founders call Mister Raw when revenue feels heavier than it should, sales lack sharpness, growth becomes messy, or capital feels further away than expected. Across current engagements: Early-stage founders move from zero to traction in weeks. Revenue climbs from 6k to 40k in months. Losses turn into profit. Capital raises evolve from small attempts into multi-million dollar closes. Fund managers step into VC and PE structures with credible positioning. Different sectors. Same pattern. When commercial direction sharpens, revenue moves. When positioning tightens, capital becomes believable. When execution cadence installs, momentum compounds. Mister Raw’s role is simple: Call the BS. Sharpen the lever. Install cadence. Stay in the arena. This is founder-level sparring. Strategic pressure. Sales precision. Revenue traction. If you want agreement, look elsewhere. If you want movement, you know where to find him.
