Background
Full-stack product engineering with CTO and venture experience.
Built by shipping products, not only advising on them.
Adrien Soulié is a CTO, product engineer, and venture builder with 6+ years of experience building software products from concept to production.
His technical background spans Next.js, React, TypeScript, and Node.js, with hands-on work across SaaS products, AI systems, back-offices, dashboards, and workflow software.
He also served as co-founder and CTO of Amigo, where the work required combining product thinking, architecture, AI systems, and sensitive user-context judgment in one product environment.
Adrien works best where product, architecture, business risk, and execution meet.
What He Builds
Systems that have to work in production, not just in a demo.
Customer-facing products and the systems behind them.
02
AI products
Voice systems, structured extraction flows, memory layers, and human review patterns built into real product behavior.
03
Operational software
Back-offices, dashboards, and workflow systems that support real teams and real decision-making.
How He Works
Product, architecture, business risk, and execution are treated as one problem.
Fewer layers. Clearer decisions. Tighter feedback loops.
01
Architecture-first
System design is handled early so the product can move quickly without compounding avoidable debt.
02
Founder-oriented
Technical advice is shaped by runway, hiring realities, fundraising pressure, and business exposure.
03
Hands-on
The work stays close to implementation, not separated into strategy theater and downstream delivery.
04
Execution-driven
Plans only matter if they reduce risk and make the product easier to ship well.
Why Stratos Exists
Because many startups need senior engineering judgment before they need a large team.
Technical ownership with execution attached to it.
Stratos exists for one reason: strong founders do not only need more features. They need a real technical owner.
The work is not ticket closing. It is understanding the product, reading the architecture, judging the business risk, and making execution hold under pressure.
That is the gap Stratos is built to fill.

Next Step
If the product needs senior engineering judgment, start with the work that matters most.
That may be an architecture audit, fractional CTO support, or a deeper AI product build. The common thread is direct ownership and clean execution.
