About Redbus Ventures
Redbus invests in early-stage ventures, predominantly but not exclusively, in the UK. Redbus allocates part of its resources to special situations such as acquiring a business that requires reorganising or purchasing an asset that seems materially undervalued. We are not a fund, we are permanent capital, so we invest for the long term and can be very patient. As entrepreneurs ourselves, we understand some great businesses can take time to flourish. Most importantly, we get, like and understand mavericks, innovators and operators. We once were them. We are proven entrepreneurs who are passionate about backing the next generation of entrepreneurs. Our lead people have founded or had senior managerial roles in start-ups that have had successful and material exits. Our portfolio companies benefit from the support both financially and otherwise of experienced entrepreneurs who have been on the same journey they are on. We aim to provide entrepreneurial insights, know-how, strategic introductions and operational experience that will help entrepreneurs have the courage to grab opportunities, avoid some mistakes and ultimately build excellent companies. We love it when people who want to talk to us manage to find someone in our eco-system who can introduce them to us. A recommendation goes a long way. If that is not possible then we would want know why you think we would be the right investors for you as opposed to any one of the other great investors out there. We can move quickly and can run at an entrepreneur's speed. Sometimes we take down a whole round, other times we act as lead and others we just participate. We like investing alongside angel investors whom have proven entrepreneurial experience and successful track record of backing brilliant entrepreneurs.
