It’s the grand finale of Y Combinator’s incubator program, where entrepreneurs have a few minutes to show off what they’ve built in the hopes of raising a seed round to help their companies stay afloat for at least a few more months (and hopefully much longer).

This year Y Combinator companies are being offered $150,000 in convertible debt by Start Fund, the fund created by Yuri Milner and Ron Conway’s SV Angel.

YC cofounder Paul Graham announced that all investors in attendance had previously invested in a Y Combinator company.

My pick among the these promising startups is Sendoid: Sendoid is a peer-to-peer and browser-based service file sharing service.There are plenty of apps out there for file sharing. Box has been a sensation and investors love it. But what makes Sendoid different.

# Senduit offer the ability to share big files easily without the hassle and clunky interface — for free.
# If you want to send a file, all you have to do is go to sendoid.com and select the file you want to transfer from your computer. It will then provide you with a URL, which you can send to the recipient to download. As long as the recipient is online, he or she can then open the link and begin download.
# Sendoid is a link-based service, your files are only passed directly between parties, so you won’t have to worry about who’s touching the data on its way.
# Sendoid is currently in the midst of raising its first angel round and is working on apps for both iOS and Android.
