You founded your own company three years ago. You initially contributed $100,000 of your own money and in return, you received 500,000 shares of stock. Since then, you have sold an additional 200,000 shares of stock to angel investors. You are now considering raising capital from a venture capital firm. This venture capital firm would invest $1.2 million and would receive 500,000 newly issued shares in return. This is the venture capitalist's first investment in your firm. How much is the post-money valuation of your firm?
