After a lot of googling, we made a Google Spreadsheet with a few hundreds of digital agencies in Peru (where our company is based), specially focused on lead generation on Facebook.
I started cold emailing and calling one by one, inviting them to join our private beta. We gave them full-access accounts and also helped each one of them to set up their accounts, so they could take advantage of Kollect's full potential.
Our private beta hasn't finished already, and we are cold emailing companies from another countries of Latam and also we are planning to launch on USA and Europe in the next few weeks. Said that, we are open to hear from you if you want to try our app, whenever you come from :)
