No escrow, but the coins are not going to be issued and distributed to purchasers until after the sale period (and the tokens are exchange-listed). Essentially, the Ether will sit in the multisig until enough has been raised to proceed AND the token has been exchange-listed to ensure liquidity. At that time, tokens will be minted and issued to purchasers.

There are details related to the mechanics of the token and sale contracts and links to those contracts in the whitepaper.

Thanks for the feedback!
