Before you pitch investors, build a minimum viable product, put it in front of customers, and learn something about product/market fit. If you can’t get this far on your own, find some idea investors instead.
Then write a 150-word elevator pitch and create a startup profile on AngelList.Our elevator pitch template is a good place to start. Spend time writing and re-writing the pitch until it’s awesome. Get feedback from good writers and entrepreneurs who have raised money.
You have 100% control over the quality of your profile and there’s no reason not to kick its ass.
