    What we do

    Hands-on Venture Builders. Unlike traditional investors, we like to get deeply involved in every stage of the journey. From validating ideas and assembling founding teams to product development, go-to-market strategies or scaling operations, we provide the infrastructure, expertise, and execution muscle needed to turn ideas into thriving businesses.

    Chasing revenue

    It is vital to talk to customers in order to understand your product and the market potential. We help our companies saving time by getting those meetings and coach them in how to close the sale.

    Scaling the tech

    Protecting runway is paramount for startups and yet it can be dangerous to cut corners. Balancing this is an art that we are very familiar with.

    Raising capital

    Raising capital can be exhausting for founders and distract them from more important work. With our network to VCs and investors we help companies prepare for upcoming investment.
