One team. Design, build, and grow — without the handoffs.
Custeo is a digital product agency based in Istanbul, working with startups and product teams who need more than a good-looking interface — they need results.
Instant credibility
More customers.
Higher conversion.
One process.
50+ successful projects delivered
We handle every stage: branding and logo design, research-driven UI/UX, and frontend, backend, and mobile app development. Once your product looks and works the way it should, we keep it moving — SEO, GEO, and ASO bring the right people to your door, while CRO and paid media turn that traffic into paying customers.
Most agencies hand a project between three or four different vendors — a design studio, a dev shop, a marketing consultant — and something gets lost at every handoff. Custeo runs design, build, and growth as one continuous process, with one team accountable for the outcome, not just the deliverable.
We work with international clients and bill in USD. Whether you're a startup shipping a first product or an established company overhauling an existing one, the process is the same: discover the real problem, design and build the right solution, then grow it after launch.
