We had conversation with one of their sales folks yesterday (www.axial.net). The pricing info we received is below. Seems pricey, but I'm curious if other searchers / buyers have had experience with them.

Pricing:
- 1% success fee 
- $1k initial account funding (goes towards your first 20 sourced deals) 
- Pay-as-you-go at $100 per-deal thereafter, or option to re-fund at one of the following: $2k for 40 deals ($50/deal) $5k for 125 deals ($40/deal) $7.5k for uncapped deal flow
