What clients say
Our current software is being used and the product-market fit feedback has been amazing!
It was a pleasure to work with Eugen. He showed a great mix between business sense and elegant, refreshing designs. He puts so much effort in understanding your business and guide you in a very structured way to the end result.
I worked with Eugen for almost three years. He showed real leadership, especially through the hard stretches, when the team needed steady direction with the product. Whenever the product needed something, he was there to help. He took every request seriously, thought it through, and delivered work we could rely on.
We worked with Eugen for complete redesigns for two of our websites and our product. Service is great, conversion rates are way up, we will definitely work with him again on all our projects.
Eugen helped us to completely redesign The Next Ad’s web app with a result that we’re proud of. He did provide great service and we will definitely work with him again!
One designer thinker for the whole product.
I talk to the team and the users, prototype the idea and ship it in code. Then I watch what people do and track the metrics. Three things hold it together.
-
0 to 1 means the whole system.
Not just the customer UI. The admin panel, the billing logic, the email flows — and the settings page nobody wants to design.
-
Every state, not just the ideal one.
Empty, error, loading, partial data, expired sessions, first-time vs returning. Every detail is a chance to make an impact.
-
Designed for millions, not demos.
I ship the code, then watch what people do, track the metrics and iterate, release after release. In total, the products I’ve designed have reached over 2 million users.

Got something real to build?
I work with your team to find the problem, build the fix and ship it in code. 47 products in 12 years. On a long contract or full-time.
Common questions
Are you open to full-time roles?
Yes. I’m open to full-time roles and long contracts.
What do you design?
AI agents and AI-assisted features, workflow and automation builders, admin panels and internal tools, and the B2B SaaS products around them. Lantern, an AI CRM with agents and a workflow builder, is one example: I was its founding designer for almost three years.
Do you write production code?
Yes. I design the product and build the front-end that ships it, working alongside your engineers. TypeScript, React, Next.js.
What results have you delivered?
Activation +15.7% at Apollo.io, onboarding +17.5% at Public Grid, and refunds down from 25.7% to 15.4% at HelloGov. In 12+ years: 47 products shipped, 3 acquired (Clearbit by HubSpot, Qualibrate by Copado, and AlphaUX).
Do you work with US companies?
Yes. Since 2020 I’ve worked mostly with US startups, remotely from Europe, plus some European companies. I work across US and European time zones.
How do we start?
Email hi@eugenesanu.com. Tell me what you’re building, where it’s at and when you’d like to start. I work directly with founders and CTOs, or with any team that has a big or interesting project, whether you’re a startup or an enterprise.
