Dedicated team vs hiring in-house in the UK

Hiring is slow for a reason
A London hire can take months once you add ads, interviews, and notice periods. That is fine if you are building a permanent engineering culture. It is a problem if you have a live product and a roadmap that cannot wait.
What a dedicated team is
Through Boolet you get engineers we hire and manage. You stay the product owner. We stay accountable for whether work is shipping. The detail is on dedicated teams.
When in-house is better
If you want someone in your office five days a week, or you are ready to manage juniors yourself, hire. We will say so on the call rather than sell a team you do not need.
When a team through us is better
You already shipped a first version. You need weekly capacity. You do not want to become a recruiter. Stack overlap with UK hours matters more than a cheap night-shift bench.
Compare that with a one-off build on services, or talk through staffing.
