TENFOLDDEVS · AI-NATIVE DEV TEAM
A — TENFOLDDEVS / VOL. 01
The SaaS era
just ended.
→ Custom software, built for you, at a fraction of what you pay for subscriptions today.
001 / PROBLEM
You pay monthly for SaaS nobody audits.
Subscriptions grow each year. Features never shrink. Your data was never yours.
— 01
Per-seat pricing
You pay for every head. Including the one that logs in once a month and clicks twice.
— 02
Prices go up, scope doesn't
Vendor raises the price or stacks a new tier. Nobody asks if you wanted new features.
— 03
Zero ownership
Your process lives on someone else's servers. So does your data. Migration always comes back.

FOUNDER
Peter Zapolski.
I started TenfoldDevs because I kept watching companies pay year after year for SaaS they barely use — and nobody told them there's another way.
My team ships a working prototype in 24h, and after two weeks you own the code and the data. No subscription rent, no vendor lock-in, no fluff.
"Software is becoming a commodity. The cost to build it is collapsing to zero — yet you're still paying pre-revolution subscription prices for tools that should cost what their parts cost."
