What we build & run
Beyond headcount, we deliver the full lifecycle — engineering, operations and consulting under one roof, including specialist public-sector work.
Ways to work with us
Flexible commercial models to build and stabilise your technical team — pick the fit for your stage, timeline and risk profile.
We assign the right engineers to your project fast, shortening recruitment cycles and reducing hiring risk while productivity ramps.
As fast as 48 hoursWe take full, end-to-end ownership of development or operations, so you stay focused on your core business while we drive delivery.
End-to-end ownershipA long-term, stable team built exclusively for you — an extension of your organisation, embedded in your process and culture.
Long-term & embeddedGlobal delivery
An in-house team spanning Hong Kong, Shenzhen and South-East Asia, coordinated from our London HQ — so we can staff fast, span time zones and keep cost competitive.
Plus a vetted bench of contract specialists we can deploy in as fast as 48 hours — letting us assemble a complete cross-functional team in a matter of days, not months.
Why Wistkey
We embed with your team and own outcomes alongside you — backed by terms designed to keep delivery predictable.
Engineers slot into your sprints, stand-ups and tooling from week one — your process, your cadence.
We map talent to the problem — the right mix of seniority and skills for your stack, not just bodies.
A 7–14 day replacement window and a one-month minimum keep delivery stable while you stay flexible.

Frequently asked
Both place Wistkey engineers inside your team under your direction. Staff augmentation adds flexible headcount to your existing project; secondment assigns named engineers to your organisation for a defined period. PM support is included in both.
Engineers are matched to your tech stack and process and typically onboard within days, not months, drawing on a bench of 127 backend, frontend, mobile, QA, DevOps and data specialists.
Wistkey is headquartered in London, United Kingdom, with the majority of its client base in Hong Kong. We offer staff secondment and augmentation across both the UK and Hong Kong, with additional teams in Shenzhen and Makati.
Engagements run on a one-month minimum, after which you can scale headcount up or down month to month. A 7–14 day replacement window is available by contract to keep delivery stable.
We partner with system integrators and startups that need to scale engineering capacity quickly, having served 120+ clients over 10 years of enterprise delivery.
With staff augmentation, our developers work inside your team under your direction, so you keep control of the roadmap. With project outsourcing, Wistkey takes an entire scope of work and owns delivery end to end. Augmentation is usually the fastest way to add capacity while staying in control.
Pricing is a transparent monthly rate per engineer based on role and seniority, with no recruitment fees, benefits overhead or long lock-in. You scale headcount up or down month to month, so cost tracks the work. Contact us for a quote against your stack and team size.
Backend (Java / Spring Boot, Node.js, .NET, PHP, Python), frontend (React, Next.js, Vue, Angular, TypeScript) and mobile (React Native, Flutter, native iOS & Android), plus QA, DevOps (AWS, Azure, Docker, CI/CD), data (MySQL, PostgreSQL, MongoDB) and AI (LLM integration, RAG, computer vision) engineers — along with project managers and solution architects. We match engineers to your existing stack.
Yes — that flexibility is the point. Add engineers as a project ramps and reduce headcount when it winds down, adjusting month to month rather than carrying permanent cost.
Both. You can take individual engineers to extend your existing team, or a long-term dedicated team built exclusively for you and embedded in your process and culture. A project manager is included on every engagement.
A 7–14 day engineer replacement window is available by contract, so if someone is not the right fit we swap them in without disrupting delivery.
