Free idea:
"Our startup wants to change the world by reselling the free $500K in Azure services [1] to outsiders for half-off, then liquidating itself. This may not be a 'traditional YC play', or 'scalable', or even 'honest', but we'll give YC half the loot (approximately $100K) and don't even require the traditional investment/convertible note. Just tell Microsoft we're a YC company! Oh, and let us know whether you like the name 'Azurbatrage' or 'Arbitrazure' better. Stretch goal: resell all the unused Azure capacity of our classmate companies – 50X the profit opportunity."
