Angel investors are private investors who provide finance and support to early-stage businesses.

The term derives from the “Theatre Angels” who were wealthy patrons of Broadway who provided the initial capital needed to get a new theatre production off the ground and onto the stage. In exchange, these patrons received a share of the production’s earnings.

Over time, the term evolved and in the late 1970s began to be applied to early stage investment into companies of all different sectors.

Angels, unlike funds, are generally investing their own money into the companies in addition to offering additional support by either taking up a board position or by providing informal advice and mentoring.

Angels often invest together in syndicates that are formed within a formally organised angel network or through an informal group who invest together often or just for one particular opportunity. The formal networks are sometimes run by an individual or group of individuals who may act to source deal flow, organise the investment documents or any number of other tasks.

Angel investing is a very risky activity as 50% of small businesses go bust within the first few years. Given this high failure rate it is not uncommon for an angel investor to want a sizeable equity stake on their investment or high interest rate if they provide a loan.

Angel investing today

Angel investing has made a resurgence in recent years as the sources of traditional capital dried up post the recessionary period that began in 2008. More recently a new and wider audience has been introduced to the concept of angel investing through the rise of online equity and debt crowdfunding platforms. These platforms have reduced the barriers of entry to angel investing by not only giving visibility to a large audience but by making the investment process much more efficient and therefore reducing the minimum investment amount of any individual into an opportunity.

Like the angel networks, these platforms source investment opportunities, consolidate the investment documents, and facilitate the act of investment.

The risks of angel investing

High Company failure rates: As mentioned earlier, angel investing is a very risky activity and has traditionally been reserved for sophisticated investors and high net worth individuals. It is unfortunate but the truth is that the most common outcome for an angel investment is that the company invested in fails. For this reason many angel investors choose to develop a portfolio of early stage investments with the hope that one or two do well and more than cover the losses made elsewhere.

Time to return: While many companies will state in their business plan that they are expecting to exit in X amount of years, the truth of the matter is much different. Angels tend to look for an exit 3-8 years down the line though some businesses, particularly those in research and development heavy fields and heavily regulated industries (think pharmaceutical) can take many times longer than that.

Lack of due diligence: Whether it’s not going through the business plan with a fine tooth comb or overlooking a minor clause in the legal documents, not spending an adequate amount of time performing due diligence can lead to problems down the line. Regardless of how well the company does or does not do, investors should always pay close attention to exactly what they are investing in and the terms at which they are investing to make sure that should the company profit, they get their fair share.
