This creates very fragmented share registers which, for a number of reasons, leave the business un-investible by subsequent professional investors.
We are already starting to see the first casualties being rejected from serious investment consideration by venture capital funds through the sheer number of small investors on the share register.
While crowd-funding delivers dollars, it can make it more difficult for the entrepreneur to get the business off the ground as there are no knowledgeable lead investors and their support networks at the table.
In contrast, one of the benefits that angel investors - usually experienced business people and serial entrepreneurs - bring is the mentoring and advisory role that they play for a new business.
Experienced investors help the entrepreneur to understand risks, manage them and help turn around or pivot their business when things don't go as planned.
For the investor, crowd-funded deals offer few or no investor protections afforded by standard New Zealand early stage investment terms, no intellectual property protection, no investor representation and a lack of due diligence by an experienced investment team.
Investing in early stage companies is very high-risk and is best done via co-investment with a professional early stage investor or angel group.
Membership of an angel group or investment in a diversified early stage seed programme - such as the Global from Day One seed funding programme - can increase the chances of success for both investors and entrepreneurs.
