I own a 100% shareholding of a company generating reasonable profits and am currently raising a round of funding primarily to scale and fund growth. In addition to a capital injection into the company, due to personal circumstance I need to release some of the equity personally. Is this common? How would this be viewed by potential investors?
Angel Investors will understand that you have a need to draw a salary... but the idea of taking their cash and putting it to personal use would be a "no-go".
If you were on your Series C of Venture Capital, raising $100M and you wanted to sell $3M of shares to buy yourself a nice house, for instance, that might be okay. But if you're raising $500k and you want to pocket $50k of that to clear your credit card debt (for instance), that would be a deal-killer.
Two reasons: (1) it shows the investors you're not great at managing your own funds, and (2) it's hard enough for a company to survive and grow with the investment that Angels provide — they definitely expect every penny to go into the company's growth.
That said, if your profits are strong and the reason for the equity sale doesn't set off 'red flags' (i.e. family medical expense?), maybe you can get away with it.
But remember: investors get pitched by hundreds, even thousands of candidate companies. That's your competition. Some of those companies look just like yours, and *don't* have a founder who's looking to use some of their cash for an early exit. So, it would be a significant strike against.
