I have been a professional angel investor for about 17 years. Over that span I have funded over 40 startup companies. The majority of these companies were pre revenue with many consisting of one or two people in a kitchen or garage. In about half of the companies I was the lead angel. Some examples of the companies I have invested in are: Xlibris.com, Scoople.It, Bikini.com, Diapers.com, Soap.com, FulcrumGallery.com, Tips.by, AppyCouple.com, GetMaid.com, LiveLook.com. HotList.com, Hooja, CarbonNanoProbes, Centrak.com, TuckerToys.com, Geometrix, CallunaVineyards.com, Ology.com, Koding.com, WeHostels.com, DoodleDeals.com, MotionMathGames.com, MakeUsAnOffer, OffTrackPlanet.com, Monaeo.com, EquityZen.com, EndlessTV.com and Spling.com I typically invest in industries I know little about but will avoid, medical, biotech and “green” industries.
