01 / Problems

Problems we solve

These are the situations that bring teams to a retainer.

  • Hard questions arrive unannouncedAn architecture decision, a stuck migration or a review before go-live needs senior judgement this week.
  • The team is fullYour engineers carry the roadmap and the daily work, and there is no room for the deep dive that unblocks them.
  • Hiring takes too longA permanent senior hire takes months, and the need is a few days a month, spread over different skills.
  • Knowledge sits with one personDecisions and context live in a few heads, and nothing on record says why the platform looks the way it does.

FAQ

Questions we hear first

How is a retainer different from a project?

A project has an end state. A retainer is a steady block of senior time that you point at whatever matters most that month.

Who works on it?

A core team leads and brings in dedicated engineers from our network where the work needs them. You know who is on it.

Can we change the size of the block?

Yes. We review it together at each quarterly roadmap review.

Do you work in our tools?

Yes. We work in your repositories, tickets and environments, so everything stays with you.

How do we start?

With a first call and a written scope, then access and a first shortlist.
