The Angel Investor Network (Sirb) was established as an initiative of King Abdul Aziz City for Science and Technology (KACST) in line with KACST vision towards a knowledge economy. Unlike all other investment alternatives in the region, Sirb is an Angel Investor Network with Angel Investors who typically invest entrepreneurs’ new startup companies at very early stages. Sirb angel investors play a critical role to proof the project, and make it marketable for a large investment round later on by large Venture Capitalist (VCs). Sirb contributes to increase the success rates of small and midsize projects at early stages through sustainable administrative and material support offered by angel investors.
