You're in the right place if...

The profiles I work best with

You're launching your startup

You raised (or you're bootstrapping), your product vision is clear, but you need to accelerate without hiring a complete tech team. You want a rapid MVP and scalable architecture.

Seed/Série AMVP en 15jTech scalable

You're an overwhelmed CTO

Your team is drowning in requests, the roadmap keeps growing, and you need senior reinforcement to unblock strategic projects. You want someone autonomous who understands quickly.

You're a non-tech founder

You have business expertise and product vision, but not technical skills. You want a tech right-hand who speaks business and can handle development end-to-end.

You want to industrialize your tech

Your business is running, but your tech can't keep up. You want to automate, integrate AI, and professionalize your infrastructure without breaking everything. You're looking for someone who understands legacy constraints.
