Senior people lead every phase. Specialised AI agents on the Agentic SDLC handle the repetitive work, and nothing ships without your approval.
Discovery
We map today's process, systems and data for test strategy; automation; and mobile and cross-browser, talk to the people who run it and agree the baseline for defects found before release and regression time so progress is measured from week one.
Design
We design the flows, roles, approvals and integrations for test strategy and automation, and review a clickable prototype with the people who will use it before anything is built.
Build in weekly demos
We build in weekly demos, starting with test strategy, then automation and mobile and cross-browser. Each release is tested on your own data and passes a human approval gate before the next begins.
Launch and support
We migrate data, train your team and support go-live. After 30 days we review defects found before release, regression time and automation coverage against the baseline and agree what to extend next.
Start small. Scale when it works.
Every engagement begins with a short, fixed-price step so you can judge the fit before committing further. See pricing.

QA and Test Automation questions.
Can you test a product you did not build?
Yes. We run QA for products built by other teams.
Which tools do you use?
We pick tools to fit your stack, for example Playwright, Cypress or Selenium for UI and Postman or REST tools for APIs.
How much will automation cost?
It depends on scope. A two-week Discovery Sprint sets scope and a fixed price. You see a fixed price and a clear scope before you commit, and changes follow an agreed process.
Do you do security testing?
We cover basic checks. For penetration testing see our application security page.
Can you embed in our team?
Yes. Engineers can join your sprints.
How do you measure success for QA and test automation?
In week one we agree a baseline for defects found before release, regression time and automation coverage. We report them at every weekly demo and review them against the baseline 30 days after go-live, so results are measured rather than assumed.
What should we prepare before the first call?
Bring a short description of how QA and test automation works today, examples of the documents or screens your team uses, and the three numbers that matter most to you. A senior specialist will use them to outline a first step and a fixed price.
