Traditional tech projects are...
Slow to start
3-4 weeks of meetings before the first line of code. At this pace, your competitor will have validated their market before you even start.
Budget overruns
Complex quotes, hidden costs, and that famous phrase "it depends". Impossible to plan with confidence.
Risky investment
Building for 6 months only to discover it's not what your users wanted. Every entrepreneur's nightmare.
Too many contacts
Sales rep, project manager, junior dev... Nobody really understands your business needs.

What my clients say
"I had this vision for Octogo.ai that I'd been carrying for over a year - creating THE reference platform for AI tool selection. Loïc accomplished in 2 weeks what I hadn't managed to achieve in a year. His pragmatic approach and immediate understanding of the challenges transformed my concept into a functional platform. The most impressive part? Not only does the result exactly match my vision, but the first users adopted it immediately."
