The site was very poorly designed, implemented and is heavily bugged with no site adminstration.
The site messaging system is extremely basic and it's support is non-existent.
Overall It's an elaborate scamming ecosystem set by group of so called "investors" and "cofounders" whom initially will push sides interested fundraising /cofounding to subscribe to a premium account which charges 3x of what they advertise (with no monthly notifications or invoices) and then as you initiate interacting on the site messaging system - this flags you/ connects you to other scamming investors asking you to subscribe 30k USD$ for non-guaranteed introductions.
The attached printscreen shows no reply on the site over a 3 months timeline - a disgrace.
Please avoid at all costs providing your credit card details and beware they make it impossible unsubscribing from that "service".
