About the atelier
Software for you, built without compromise.
Maréchal-Winthrop is a boutique software company that spent years building for a handful of clients, with a single guiding principle: that software should work for the users that own it. Billion dollar companies harvest your data, scatter your attention, and sell your secrets for ad tracking. The marketplace is flooded with products that promise everything and deliver nothing. We believe there is a better way, and that we can return to a time when product design centered the user.

We started with one client.
Maréchal-Winthrop began in a single room, building one piece of software for one client who valued performance and taste over scale. Years later, we still build every release by hand, still ship on our own schedule, and still put a name behind every line of code before it goes out the door.
TODO: change this Our roster was intentionally small. We'd rather build deeply for a few than broadly for a crowd, and that instinct hasn't changed.
How we work
01
Performance, always
TODONo bloat, no third-party trackers, no ad exchanges bolted to the backend. Every millisecond you wait for a page is a millisecond we spent optimizingremoving, not adding.
02
Built by hand, mostly
TODOAutomation drafts and scaffolds. The architecture, the interactions, and the finishing details are worked by engineers who've shipped every release personally. It's slower. It shows.
03
Made to last, not to extract
TODONo dark patterns, no data harvesting, no planned obsolescence dressed up as an update. What you use is yours, and it's built to keep working.
On craftsmanship
"We don't ship features by the roadmap quarter. Every decision is made for the person who has to live with it — sometimes months before a single line is written."
— Aurélien Maréchal, founder
No growth hacks. No engagement loops. No monetizing your attention while calling it a free tier. Exclusivity was never a marketing device for us — it was the only way we knew how to build something worth using, unlike the multibillion-dollar platforms built to harvest your data and enrich their shareholders.
