Grantoo cofounder here. We'd love to hear what the HackerNews community thinks of what we've built. We're a team of game developers frustrated with the options out there for engaging + monetizing players by delivering value, not showing ads, so we decided to take matters into our own hands. With PropellerSDK, we are matching top games with Fortune500 brands who will sponsor tournaments with real prizes (tuition, charity grants, etc) for players. Games get great features + a new revenue stream, players win prizes, and brands benefit from the most effective mobile advertising channel currently available.
tl;dr: platform to add server-side multiplayer features (challenges, tournaments) as well as monetization through sponsored tournaments. sounds pretty win/win/win to me..
Cool. Looking forward to trying it out!
Stoked on this release guys! Cheers from North Van.
