✦ One team · the whole build
Three disciplines. One delivery engine.
Haystak isn't a body shop you manage. It's a team that owns outcomes - while you stay the decision maker.

✽ The 3 questions everyone asks first
Answered here, not on the call.
Q01Fixed first milestone
How is this different from hiring an agency?
Agencies sell hours; we sell working software. Every engagement starts with a fixed-price milestone that puts something real in front of your users, and the code lives in your repository from commit one.
Q02Any stack, any platform
Do you work with our existing technology?
Yes. We've built on modern React and mobile stacks and inside .NET, Java and PHP estates that are older than some of our engineers. We adopt your stack rather than forcing ours.
Q03You own everything
Who owns the code and the infrastructure?
You do - the repositories, the cloud accounts, the documentation. Support is a choice you re-make every quarter, never a lock-in.
Who do you work with?
B2B companies from 20 to 2,000 staff.
Where is the team?
UK and EU based engineers, one timezone.
Bespoke software, built properly. Let's scope yours.
Twenty minutes. Bring the problem, the constraints and the deadline - you'll leave with an approach, a rough shape and an honest answer on fit.
