Lack of time is one of the typical issues founders face. Contacting investors takes time and is undoubtedly crucial. Since time is ultimately the most valuable resource, I am happy to see a tool that can help entrepreneurs save a significant amount of time.
Stay away from SpamZilla they are refusing to provide me a refund because I opened a PayPal dispute, the domains they find are not worth the money you pay monthly, you are better off going to the free expireddomains.net website to find expired/expiring domains as you would find better or even the same domains they have listed. Going on since the end of July and they still refuse to provide me with a full refund, shamefull business pratices.
