The sector's own numbers argue for cheaper pipeline, not more headcount

The Data City tracks 3,299 UK SaaS companies employing around 161,000 people on £121.9bn of combined turnover, which sounds enormous until you filter to your actual segment and find a buyer universe of a few thousand accounts rather than a few hundred thousand. That is an argument for precision, not volume. SaaS Capital's 2025 benchmarks put median private B2B SaaS growth at 22 per cent, down from 25 per cent, with median net revenue retention sitting close to 101 per cent, so almost all growth now has to come from new logos. Ebsta and Pavilion recorded win rates falling to 19 per cent in 2025 from 29 per cent the year before, and mid-market cycles have stretched to about 92 days against 68 days in 2019 as buying committees grew. Beauhurst had UK deal numbers in Q1 2025 at their lowest since 2018, with bridge rounds doing work that priced rounds used to do. Set that against a 16 month median CAC payback and the position is clear: you need more qualified first meetings, you cannot responsibly buy them with headcount, and you cannot afford two quarters to find out whether the channel works at all.
