Sollas

Sollas is a product design agency for founders of crypto, fintech and AI apps. We design apps that people understand and trust, and we code the screens right into your product, so the live app matches the design.

Most founders come to us with the same problem: people sign up, then get confused, don't trust the app with their money or data, and leave. We find where they get stuck and fix it.

What we do:

• Product design for iOS, Android and web apps
• Onboarding, KYC, deposit, swap and trading flows
• Dashboards and design systems
• Websites and brands for crypto, fintech and AI products
• Front-end code for the screens we design
• Testing new screens with real users

Results:

• Unhosted (self-custody wallet): after we made sign-up shorter and added seed phrase backup to iCloud, wallet creation went up 75%. 100,000+ wallets were created through the onboarding we designed.
• Continuum (Web3 learning app): designed from zero. Average session time grew 180% from v1 to v2, the app got 10,000+ downloads and #1 Product of the Week on Product Hunt, and the team raised $2M.
• New Gold Protocol (DeFi on BNB Chain): brand, website and a staking dApp with 100+ screens in 3 months.

How we start: a 20-minute call, then a paid test week for $1,000 that counts toward the project. In 48 hours you get a list of what to change, and by week 2 the first changes are live. In month 1 we test the new screens with real users, and where people still get stuck, we fix it at our cost.

Vadim, the founder, has designed products since 2017 and crypto products since 2018, and took 1st place at the UDC design battle in 2024. He leads every project. You talk directly to the designers and the engineer doing the work, with no account managers in between, and every 2 days you get a short video update.
