The job ad is losing its grip on UK technical hiring

On 30 September Juicebox, an AI recruiting platform backed by Sequoia Capital and DST Global, opened its first international office, in London’s Soho. According to the company’s release, it already serves more than 1,000 customers across Europe, the Middle East and Africa (EMEA) and plans to grow its London team to more than 50 people over the next year. The move follows an $80m (£60m) Series B at an $850m (£640m) valuation, announced in March.

The release is a sales document, and the customer voices in it were chosen by Juicebox. But one line in it deserves the attention of every UK technology employer. “Less than 20% of our hires over the last year have come through inbound,” said Joshua Voisey, head of talent at Omnea, a London-based procurement platform.

Put the other way round, more than four in five of Omnea’s hires in the past year came some other way. The release does not say how the rest split between direct approaches, referrals and agencies. Still, when a London employer fills fewer than one in five roles from the people who apply, the job ad is no longer its main hiring channel.

For UK tech employers, the lesson is structural. If Omnea’s experience is typical, hiring for scarce technical roles now works more like outbound sales than advertising, and people teams that budget, staff and measure recruitment around applications are organized for a market that has moved.

Why the front door stopped working

Juicebox’s explanation is that AI has flooded the inbox. Its release says generative AI has made it easier for candidates to tailor resumes, write cover letters and apply to roles at scale, leaving recruiting teams with “more volume but not necessarily better candidates”.

Greenhouse, which sells hiring software and so has its own interest in the problem, reported the same pressure in its 2025 AI in Hiring Report, published in November 2025. Of the US recruiters it surveyed, 34% said they spend up to half their week filtering spam and junk applications. The survey covered 4,136 job seekers, recruiters and hiring managers in the US, the UK, Ireland and Germany, but that figure is for the US, not the UK.

David Paffenholz, co-founder and CEO of Juicebox, put the consequence this way: “The next era of recruiting will look much more like executive search, not only for senior leaders, but for every high impact important role within a business.”

What the fastest hirers are doing

The two London customers in the release describe a market where scale-ups go looking rather than waiting. Fonoa, a London-based tax technology company, grew from 115 employees in October 2025 to more than 260, which is more than double in under a year. The release says that growth came with help from Juicebox. Adam Lawrence, Fonoa’s global go-to-market talent lead, said the company is “constantly competing with fast-scaling SaaS and AI companies for the same top-tier people”.

Voisey said Juicebox’s agents can generate 10 to 15 engineering calls a week for Omnea and have cut its recruiters’ sourcing workload in half, giving them more time to speak with candidates. Those are a customer’s claims in a vendor’s release, and they have not been independently checked. The shape of the work is the point: less time screening people who applied, more time finding specific people and starting a conversation with them.

That changes what a recruiting team is. Once most hires start with an approach from the employer, recruiters are doing the job of sales development: building target lists, writing outreach and turning first calls into interviews. The risk for employers that have not noticed is that they keep staffing and measuring the team as an administrator of applications.

Measure the pipeline before buying the tool

The first step for UK people leaders is to find their own number. What share of last year’s technical hires came from applications, from referrals, from agencies and from direct approaches? Without that breakdown, a vendor’s case study is the only data in the room, and Omnea’s figure is one company’s experience, not a market statistic.

If the inbound share is low, the recruiting function should be run with the measures a sales team would recognize: sourcing capacity per recruiter, reply rates to outreach and conversion from first call to offer. Applications per role and cost per applicant can look healthy while the roles that matter are filled by other routes.

Outbound hiring also raises the bar on everything an employer says about itself. A candidate approached cold did not come looking, so the role, the pay and the reason to move have to be clear in the first message. Employers that cannot state those plainly will find that better search tools simply put a weak pitch in front of more people.

The job ad will not disappear. But at scale-ups such as Omnea, it is already the fallback rather than the plan, and people teams should be judged on the candidates they find, not the applications they receive.
