Series B
$25.0M

The London startup secured $25m from backers including eBay and Andreessen Horowitz to automate secondhand fashion logistics.

"Most people have no idea what happens to a piece of clothing after they part with it. It travels thousands of miles, gets sorted by hand in a warehouse in Karachi, and finds its way back to a vintage shop in London or New York, if it’s lucky. We started Fleek because that system is broken, the market it serves is exploding, and nobody is building the technology and infrastructure to fix it,"
— Abhi Arora, Co-founder and CEO
Series A
$12.5M

The financing round was led by Infinity Ventures with participation from Sella Direct Ventures, Frontline Ventures, and Y Combinator.

"The competency of a financial institution is not building financial crime technology. It’s such a complex, T-shaped domain. That’s why I decided to start the company myself,"
— Baran Ozkan, Co-founder
Seed
£1.8M

The seed round was backed by Y Combinator and will support US market expansion and product development.

"Crimson is built specifically for litigators, giving them a faster and more reliable way to understand the case file, assess the evidence, and produce high-quality work grounded in the full matter context."
— Mark Feldner, Co-founder and CEO
Series A
£8.1M

The oversubscribed funding round was led by Portage Ventures with participation from F Capital and existing investors.

"Happl began with a simple belief: benefits should be easy to understand, easy to manage and easy to implement. What we’ve built goes far beyond that, a global platform that removes complexity at scale and connects employees with solutions that truly reflect their needs."
— Ben Towers, CEO
