CPO & Co-founder Tech: How I built a B2B SaaS from scratch with low-code AI tools

July 14, 2025: The Hôtel Molitor M Gallery signs. Our product is only 30 days old. 10 years in the product (Logitech, Ledger, Fairmat), no line of code before Uniforms. We could have waited 6 months to find a CTO. I chose to build it myself to meet the need identified during our many field interviews: hospitality lacks digitalization and loses money on what it doesn't measure. Uniforms: the first intelligent inventory management digital platform in hospitality. We make the invisible visible. 6 months later: → 5 daily paying customers → 28 customers in the pipeline → 10 convinced investors → €250k raised in pre-seed → French Tech BPI Grant → A CTO recruited to scale The (non-linear) journey: - Start: euphoria with low-code tools: Bolt.new, V0, Lovable - Month 2: total crash, hardcoded code - Month 3: burned credits, uncontrollable tool - Month 4: technical debt, complete overhaul with a first significant but decisive expense - Month 6: multi-tenant SaaS, +1500 movements recorded I learned React in 1 week on YouTube. Created a Figma + prompt engineering framework that divided my credits by 4. Pivoted the tool at the right time. What you will discover: - The 8 phases: tool exploration → live prototyping with clients → crashes and learnings → optimization → migration → multi-tenant → scale with a CTO. - Concrete learnings: Figma/Notion/prompt engineering framework, signals for changing tools or recruiting, how to steer AI instead of being steered. - Why it's unique: A complete B2B SaaS in production, built with low-code AI. Concrete, not theoretical. Actionable today. - My message: AI tools have not replaced my skills. They have amplified them. - PM + Design + Curiosity + Resilience = Product in production. If I could do it, you can do it. I'm here to show you how.
