Sollas is a product design agency from Kyiv, Ukraine, 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.

Describe the scope of work in detail. Please include a summary of key deliverables.
Together with Sollas we performed a lot of research with doctors and women in our community to discover the top problems to solve for our target populations / customers. From those user conversations, Sollas created interactive wireframes for users to test and for us to refine before starting UI design. That worked very well by giving us insights for improvements already in the first week.Once that work was finished Sollas moved on to the design phase which was so fast.
It was great to keep the excitement level of everyone very high by doing this work so quickly. The key deliverables were:
Personas and user stories in Notion.
Flowchart in FigJam.
An interactive prototype of the entire mobile app.
UI designs of all app screens are nicely organized in Figma.

RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Our collaboration with Sollas has been quite the revelation. In just a short span of 4 weeks, they managed to transform our concepts into tangible designs, which in itself was an astonishing feat. What's even more remarkable is that we had a functioning product within days, thanks to their alignment with us on speed. We achieved what many every startup founder needs, which is a proof of concept launch and a website in just 7 days.
The reception from users was very positive, especially for a product in its infancy. Additionally, over the next 4 weeks, they diligently refined our project based on the invaluable feedback and user insights we gathered from our rapidly growing user base of 2,200. Through this collaborative process, we were able to make 16 iterative changes that brought us closer to achieving product-market fit.
The results speak for themselves - 65.5% monthly to weekly (MAU/WAU) stickiness, and a whopping 198% growth, all within a remarkably short time frame. And we started generating revenue in the 4th week. Sollas took ownership of the project and desired results. But it is not just about measurable outcomes; it was a testament to their agility and alignment with our vision.
It's been an invaluable partnership that underscores the power of collaboration with the right partner that has help many startups and just gets it because they have lived it and as such have internalized that dedication to speed and quality.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
We coordinated through Slack for project management, while Figma was the go-to platform for contextual commentary. Sollas amazed us with their speed, often updating Figma rapidly. Their 7-day sprint approach provided daily updates, and their organization of Figma files greatly impressed our developers, making the design-to-code process smoother. Deliveries were consistently on time or ahead of schedule. Their responsiveness was excellent, with frequent and effective communication on Slack.

What did you find most impressive or unique about this company?
What stood out most about Sollas was their remarkable speed and seamless collaboration. Their ability to rapidly iterate and update designs, often within a day, was truly impressive.
The 7-day sprint approach they employed, along with their strong organizational skills in tools like Figma, ensured efficient communication and prompt deliveries. Their proactive and responsive approach, coupled with their clear understanding of our need for speed, made them an invaluable partner in our journey toward product development and market fit.
Are there any areas for improvement or something {provider_name} could have done differently?
Nothing they could improve. I have been a product designer myself for over a decade and Sollas is everything I would want to see if I hired a designer or agency/service and more. They really set a new standard that I think very few people or services/agencies in UX/UI/Product Design can meet.
