The working together part comes first, then the connecting. Purely doing matchmaking is too hard and inaccurate imo, it is easier to find things that people find mutually interesting and get them engaged together through it.

My site is largely unconcerned with funding right now, there are already excellent resources to get it. And scammers would be wasting their time: much like most startups, lots of people try really hard and get nothing out of it. Why scam the guy you will have to work hard to help and will probably get nothing?
