Dmitry Tsepelev 
I’m a product builder who figures out what to build, designs, codes, and gets it into users’ hands.
Lately, I’ve been solving human focus from first principles:
- Built Hyperfocus, an AI-powered planner for Mac that turns goals into daily progress (#2 on Product Hunt).
- Founded a research-driven training program loved by product leaders from Miro, Booking.com, Intuit, Wolt, and others.
Previously, I led product at Yandex.Checkout (#1 payment provider in Eastern Europe, ~$6B in annual payment volume across 22,000+ businesses), where I grew from DevEx PM to Head of Product:
- Designed, launched, and scaled a new developer platform, payments API, and SDK suite from 0→1 – unlocking integrations with Apple, Farfetch, Adidas, iHerb, and Joom.
- Led a team of 7 PMs to expand the product from an online payment processor into a financial platform (B2C marketplaces, C2C escrow, tax-compliant contractor payouts), helping drive 30% YoY net revenue growth.
Before that, I co-founded Landy – an automated website personalization tool selected for the YC Open Office Hours program.
