1. Predictious uses the more traditional market-making model (as in financial markets). This is fine in more liquid markets, but in markets with habitually sparse bettors as is usual with prediction markets, it is better to have an in-theory infinite liquidity betting pattern (e.g. modified parimutuel, as Zentrade uses) so that you can make your bets at any time rather than waiting for someone to publish a price.
2. Reliability and trust are big things to us. How would you suggest we implement this to show customers?
3. 2016? Not sure I'd be betting on either there...
"Zero commission" does not actually mean zero commission.
The commission just ends up being baked in to the prices they show you.
e.g. If the market (institutional) bid/offer for MSFT were 39/41, they would show customers prices of 38/42. For an order of $1000, that would mean they charge you $25 of implicit commission on the trade. It just doesn't show up on your bill.
Get real. Their only innovation is hiding fees from their customers, not reducing them.
How often are good startups born from co-founders who meet each other in this way?
I myself am looking for a good partner to work with, but am a bit hesitant about looking outside my immediate circle of friends and acquaintances for partners. How does one get over the initial hump of building rapport/trust?
Assuming this role-call is for the upcoming YC batch, have there ever been any teams that were accepted who were introduced this way?
