Angel groups are collections of investors that share deal flow and diligence. They typically invest in high-growth companies in large markets with great teams and disruptive business models or technologies. Investments are usually made through equity stakes at a negotiated share price, with the hope that the share price will increase upon exit. Angel groups can bring significant funding and business experience to early-stage deals, along with large referral networks and domain expertise, but their investment process is typically slower than individual investors, taking 2-6 months.
