Better than, well, all of them!
I have worked with SaasZilla both as a customer, and as a vendor. As a customer: Amazing support, amazing products and all of their deals are vetted! Unlike other companies eventually the deal goes sour, Kai and his team take a lot of time to understand the founders, and the tool to ensure that it's to their standard. As a vendor: I can confirm the above. haha. The vetting process was longer than other platforms we listed on. What this told us was that he cares about the deals that he brings to the market and his customers. Hands down, the best platform out there by far!
