Partner for startups & enterprises
Software development
services that scale.
11Seas works across the whole product lifecycle rather than a single slice of it — from the first research session through design, engineering and QA, to launch and the support that follows it.
Most engagements use several of these together. You can start at any stage, and you do not have to commit to the whole sequence.

How we work
One continuous flow, not a relay
Each phase ends with something concrete you can review — validated scope, working prototypes, tested releases — rather than a status report.
Discover
Research, user interviews and scope validation before anything gets built.
Build
Senior engineers on web, mobile and SaaS, with code review throughout.
Validate
Test strategy and automation built into each sprint, not bolted on at the end.

Questions
We move through discovery, design, build, and launch as one continuous flow. Each phase ends with something concrete you can review — validated scope, working prototypes, tested releases — rather than a status report.
Yes. We regularly provide QA for products built by other teams, whether as an ongoing function or a one-off release audit — and the same applies to design, analytics and support.
Yes. We start with a short audit to understand the architecture and current state, then work incrementally. We don't propose a rewrite unless the numbers genuinely justify it.
Commonly React, React Native, TypeScript, Node.js, Python, Laravel, Swift, Kotlin, Flutter, PostgreSQL, and AWS or GCP. We pick per project rather than defaulting to one stack.
Most discovery engagements run two to four weeks depending on scope and how much prior research exists. Complex regulated products can take longer; a focused MVP validation can be shorter.
Yes, following a technical audit so we understand the system before taking responsibility for it. The audit also surfaces risks worth addressing early.
