Look for Sublime Science on AmazonFull story →Marc Wileman pitched loud, splashy children's birthday parties built around safe experiments designed to look like proper mad science, in series 13.
Kids can still book a party today, though the years in between have not been an unbroken run of smooth growth.
A Small Ask for a Confident Founder
Wileman gave up just a tenth of the company for £50,000, the kind of low equity offer a founder makes when the existing revenue already speaks for itself.
Nick Jenkins and Sarah Willingham funded the deal together. Jenkins had already built one major consumer brand from scratch, while Willingham's background in hospitality suited a company whose whole product is running events smoothly at volume.
Award-Winning Growth, Then a Wobble
In the years after the pitch, the company grew substantially, picking up a Queen's Award for Enterprise and being bought by Hyphen Capital in 2018, at one point running more than 5,000 events annually.
That success did not shield it from financial pressure. In September 2024, paperwork surfaced showing the operating company filing what's formally termed notice of intention to appoint administrators, essentially a protective step taken mid-restructuring. The brand carried on regardless, and heading into 2025 and 2026 the site was still open for bookings, pointing to a tally past 10,000 parties run to date.
The Fuller Picture
Bookings being open is only half the picture. The 2024 filing belongs in it too, since it marks a genuine restructuring event rather than an unbroken decade of smooth growth.
Live events carry heavy, ever-rising costs in staff, travel and venue hire, and a business can have a loyal customer base, reviews here certainly suggest one, while still running into a genuine cash squeeze. Both things appear to be true here, and the company kept trading through it.
