The 37X Ventures identity launches as the home for the team's current portfolio and operating history.
Leadership
Founder-led operating team
Doug Scott created Redbrain in 2016 and ran it for nine years, bootstrapped throughout with no outside investment, before stepping back from day-to-day operations in March 2025. Earlier, he built Carrentals.co.uk and DiscountVouchers.co.uk under ASAP Ventures (2001–2016), selling both in 2016. Today, Doug Scott and the 37X Ventures team bring that experience to every current project and programme relationship.
How 37X Ventures works
Projects are designed around genuine user intent, useful information and appropriate merchant matching.
Brand guidelines, programme terms and restricted promotional methods are treated as operating requirements, not suggestions.
No proprietary black boxes — traffic sources, placements and testing plans are shared on request, not hidden behind the application.
The objective is durable incremental demand, not low-quality volume or activity that conflicts with other partners.
Historical projects
Past projects spanning commerce technology, travel comparison, consumer discounts and digital publishing demonstrate the operating experience behind 37X Ventures today.

Doug stepped back from day-to-day operations in March 2025.
