Design that powers growth

Lumi Studio – startup founders who design and build products for startups. We're not your typical agency – we're startup veterans who've built and sold our own companies, worked at tech scale-ups, and understand the real pressures of building products that actually ship and grow.

We integrate as part of your team, not external contractors. Having lived through the startup journey ourselves, we speak your language, understand your constraints, and focus obsessively on business metrics and user outcomes – not just pretty deliverables.

Our approach is ruthlessly practical: we identify what actually moves the needle for your business and users, then design and build those features that drive growth. No design files sitting forever in folders – just shipping products that 25+ million people have used across our client base.

We work with ambitious startups across US, UK, and Europe, specializing in SaaS platforms, subscription mobile apps, and AI products. Because we've been where you are, we know exactly what you need to get from idea to market-ready product.
