Look for a partner that can add value, reach out to prospective merger and acquisition officers or raise a seed round?

As a 500 Startup mentor I would suggest the following 1) Blog about distribution, design and data. Those are the things that 500 values most and usually the fastest way to get on their radar. 2) Interact with @davemcclure (and all other partners) on Twitter 3) Attend geeks on a plane or other events they host. It's all about relationships and perception, so create opportunities to increase the probability of showing them that you have skills that are relevant to the companies they invest in. Hope that helps.

I'm a small-time investor and have been working for and with startups for 13 years. The time to take seed capital is: - When you've proven demand for your product by making sales. - When you have at least one repeatable, predictable, and profitable system in place for selling your product. - When taking an equity investment would let you grow the company faster than the other means that might be at your disposal: bootstrapping, debt financing, organic growth, joint ventures, etc. There's a trade-off. You want to get the idea validated up-front and get as far as possible as you can on your own, but not spend so much time doing this with meager resources that the opportunity passes you by. You don't want to give away the whole company to your investor, but you also don't want to stunt your growth and give up huge potential profits just because you were holding out for slightly better terms. The better your sales, and sales growth, the better the valuation you'll be able to negotiate. A great idea and a proof-of-concept alone are worth basically nothing. A company with sales is worth more. A company with sales growth is worth even more. A company with month-over-month sales growth, ongoing relationships with customers who repurchase, and steady-state profitability is worth *much, much* more. (Steady-state profitability means that if the company's number of customers stays the same, the business operations turn a profit. Often, early-stage companies that have a recurring-revenue business model will spend more to acquire a new customer than they earn from the first sale; the cost of acquisition is amortized over the lifetime of the customer. This is because they want to grow their recurring-revenue base and increase future profits at the expense of short-term negative cash-flow.) All that being said, if you think you will need venture capital funding in the future, you should start looking for it long before you're going to need it. Have a "Plan B" in place, too. Don't get stuck with your back up against a wall, hoping and praying that your seed round will close before you start bouncing checks. If your investor knows you're going to go bankrupt without the investment, they have a lot of leverage for getting very favorable terms!

Wow, sounds like you have an amazing profit margin. The key is GROWTH. Continuous and stable, with the ability to predict future growth. Therefore, your market niche is very important, to feed the growth curve within an order of magnitude and can't be too vague. As others have mentioned, investors look for a $100-200 million valuation potential, as well as the ability to morph or expand as needed. Contact me if you want to discuss more.

AngelList is your best bet. Since you're asking the question, chances are you don't have a way to get introduced to these investors. The simple truth (like it or not) is the chances very low that you'll get a deal done without an introduction from someone they trust. AngelList can help with that, so can going to networking events. And finally, If you're the introverted developer type, you can also get their attention by just building something really cool on your own, followed by some serious traction. Arguably the best strategy of them all.
