Founder-to-Founder Startup Review & StrategyGuillaume Derivery
🛬 Brutally honest, experience-backed feedback on your startup—from idea to market fit including product, tech, market, and business model—from a founder who’s launched 10+ startups.
We’ll challenge assumptions, identify blind spots, and clarify what actually matters to reach market fit and revenue—fast.
What We Cover:
🏛️ Market & problem validation
🎰 Product, MVP & differentiation
🤖 Tech stack & development direction
🤑 Business model & pricing
🌱 Go-to-market, growth & feedback loops
🚀 Launch, scale & decision milestones
I help startup founders gain clarity on what they’re building, why it matters, and how to make it work in the real world.
With 10+ years and ~10 startups launched as a founder (CTO/CTPO) or operator, I offer founder-to-founder sessions to challenge your assumptions, sharpen your product, and define a realistic path to traction and revenue.
🚑 No fluff. No validation. Just clear thinking and actionable direction.
What's included
📗 Brutally honest written documentation
A clear, no-BS document breaking down your startup as it actually is (not how you wish it was):
problem clarity, market reality, competitive position, product & MVP scope, tech choices, and business fundamentals. Blind spots, weak assumptions, and wasted effort are explicitly called out.
☣️ Founder-level feedback you won’t get elsewhere
Direct, experience-backed feedback on what’s working, what’s broken, what’s missing, and what you should stop doing. No validation, no sugarcoating — only decisions that improve your odds of survival and success.
🛣️ Profit-first strategic roadmap
A realistic, execution-focused plan designed to move you toward revenue and market fit, with clear priorities and trade-offs for:
- Next 7 days
- Next 30 days
- Next 3–6 months
💡 Decision clarity & next-move alignment
You leave knowing exactly where to focus, what to ignore, and which paths are dead ends. Clear guidance on whether to double down, pivot, simplify, or kill features — so every next move is intentional and measurable.
