3BL is a private, boutique investment firm with the primary goal of creating long-term value across the portfolio through direct or indirect investments into startup companies.

We are now running and operating an ai venture studio. Read more about it below.

AI venture studio \

3BL operates an ai venture studio where we research, develop, and co-found ventures with builders and founders at the earliest stages. Sometimes we match the right people with our own ideas to bring them to life. More often we partner with exceptional teams that have strong ideas and enter as a co-founding partner — supporting with coaching, strategy, network access, recruitment, product development, funding, and more. The goal is always the same: to build next-generation, high-value ai companies while embracing the journey.

We believe that having an engaged founding partner early on — one who can offload work from and actively support founders, is key to success. Other investor types, such as vc’s, can come in later, when the time is right and the essentials are in place. What early teams often need is something quite different, and trebl aims to be that difference. 

Our philosophy is simple: the team is everything. We don’t set expiry dates, charge fees, or optimize for quantity. Instead, we select people carefully and work alongside until the end, using our own self-developed model.

The ai venture studio is industry-agnostic, but every idea and startup we engage with is ai-native, designed for the new age of intelligence.

If you have an idea or are early in your journey, let’s chat. The best companies begin as conversations.
