Reachable Buyer Map

Prepared for Jack Brooks · Deazy · August 2026
Development capacity gets bought by two buyers who never meet: the agency lead who has just won work they cannot staff, and the in house tech leader who cannot hire fast enough to hit a date. Below are the UK segments those two sit in, who signs inside each one, and roughly how many companies are there. It describes the market rather than your business, and there is nothing to buy at the end of it.
Digital, product and marketing agencies
The buyer with the most urgent version of the problem, because their capacity gap has a client attached to it and a date already agreed. They buy quickly, they buy repeatedly, and they are the least likely to run a procurement process. The tradeoff is that they resell the work, so the conversation is about margin and reliability rather than about capability.
Who signs: delivery director, head of engineering, managing director, and at the smaller end the founder.
3,000 to 3,800
UK agencies with a build or delivery function at 10 people or more
Venture backed scaleups
The clearest trigger on this page. A raise closes, a roadmap gets committed to a board, and hiring cannot move fast enough to match it. The window between the money landing and the first engineers starting is short, and it is when this decision gets made.
Who signs: chief technology officer, VP of engineering, head of product, founder.
1,200 to 1,700
UK companies with a disclosed funding round in the last two years at Series A or later
Software vendors and product companies
Steadier and less dramatic than the scaleup segment. They have a permanent roadmap backlog, an existing engineering culture and strong opinions about who touches the codebase, so the sale is about fit with an existing team rather than about speed. Larger over time, and much harder to displace once it lands.
Who signs: chief technology officer, VP of engineering, director of product, head of platform.
4,000 to 5,000
UK software and technology product companies at 20 people or more
Mid market employers with an in house tech function
The underworked band, and the largest on this page. Big enough that software delivery is a real function with a budget, small enough that there is no preferred supplier framework locking anyone out. They are also the group least likely to have heard of any of the options.
Who signs: IT director, head of digital, chief information officer, transformation or change lead.
8,000 to 10,000
UK employers at 250 people or more across sectors that run their own software
Consultancies and systems integrators
They subcontract constantly and almost never advertise it. The relationship is slow to start and unusually durable once it exists, because being on an approved supplier list survives the person who put you there. Fewest companies, highest repeat value.
Who signs: practice lead, resourcing or capability director, delivery partner, head of engineering.
700 to 1,000
UK technology consultancies and integrators at 50 people or more
Sponsor backed portfolio companies
Where a technology mandate arrives from outside the business and lands on someone who has to deliver it without a team. Worth being straight about the limit: ownership is not published in a form anyone can filter, so this group cannot be pulled from a register. It is identified one company at a time.
Who signs: the portfolio operating partner, the incoming chief technology officer, the managing director.
Not filterable from public data
identified one at a time from deal announcements and leadership changes; the difficulty is the reason it stays open

Where the openings are

1
This is bought at a moment, not on a cycle. A pitch won, a round closed, a senior engineer resigning, a date that slipped. Those moments are visible from outside if someone is watching several thousand companies for them, and completely invisible if you are waiting for the right person to remember the name.
2
The unfilled role is the strongest public signal there is. An engineering role that has been open past a certain point is no longer a hiring problem, it is a delivery problem, and a hire will not fix it in time. That signal is published by the company itself, refreshes weekly, and almost nobody works it as a targeting input.
3
Agencies and in house teams need two different first lines. One buyer is protecting a margin on work already sold. The other is protecting a date. Those are different sentences, and a single channel tends to keep saying whichever one worked last quarter. Two named audiences is a solvable reach problem.
4
The mid market band is the largest and the least contested. Roughly 8,000 to 10,000 UK employers at 250 people or more run software they cannot staff properly, sit below the threshold where the large integrators bother, and are rarely on anyone's outbound list. They are reachable by role, and the role is easy to name.
Built from public market data, public company registers and published funding records, counts banded deliberately. Headcount bands are drawn from filed employee numbers, which lag by up to a year and understate fast growing companies. Ownership structure is not published in a filterable form anywhere, so sponsor backed companies are described rather than counted.
