Co-Founder, Product, Project & Scale
Roger Grekos leads product at BrainStormers. 12+ years in product at X, the moonshot factory, PayEm and Find.co: validation, pricing, growth and scale.
Startups bring him in to test an idea, cut a crowded roadmap to one bet or set a price. Scale-ups and established companies bring him in to plan growth without breaking what already works.
The drawing shows two versions of a sign-up screen and, under it, the test that decides between them: an even split, results with confidence intervals and a decision.

THE APPROACH
How Roger Grekos works with your team
Roger starts with the people who will use the product. Before a roadmap or a pricing page, he looks for evidence: interviews, usage data, sign-ups and the reasons people leave. The first thing you get is a short written view of what the evidence supports, what it does not, and the one bet worth making next.
For a new idea, that means idea validation before anyone commits to a build, then a discovery phase once the problem is clear. For a live product, it often starts with user experience testing, where real users try the key flows. The findings feed a UX audit that ranks fixes by how much they matter.
When a team needs a product lead without a full-time hire, he works as a fractional CPO, running the roadmap, the positioning and the decisions around them. Our SaaS design services turn those decisions into screens a team can build. Pricing and packaging come next, then a plan for what has to change as users, team and revenue grow.
Each engagement ends with a plan your team can keep using: the evidence, the decisions and the reasons behind them.
I build the products, systems and operational foundations that let companies scale.
