Before investing anywhere you should take a close look at the company & the team. For me they look good especially because the team is very good. Mahoney made a similar arbitrage software for T3 Trading & Splunk back in 2005 (or 2006, not sure) so I think those guys know what theyre doing. But you should check it yourself .
Agree, you should first check them out. I saw they all have linkedin profiles so that should be pretty easy anyways.
