Where to find extra 20 beta users for our lead generation tool?

In September 2020 we had a successful launch of our Chrome extension - Prospect Role - that helps you find LinkedIn profiles with email addresses. With little marketing we have build the user base of 1700 registered users and growing.

I've been preparing a list of beta users for our new cloud solution that might be a good fit for our lead generation tool and I got quite a success with SaaS and Indie events. After attending Indie Worldwide events lead by @AntCas and SaaStock, I got more than 20 networking sessions in total and follow up meetings that got me 20 relevant beta users for my list.

After providing short description of Prospect Role, I was happy with the response where almost everyone happily accepted to try it out.

My pitch: Get a clean spreadsheet of highly-targeted people with their verified business emails, company phone numbers and LinkedIn profile URLs. Expect no confusion with credits and the fastest generation of clean spreadsheet with leads and company data.

Example: You can generate a massive list of Product managers from Boston that work for a company in IT industry with 50-200 employees. All that with few clicks

For extra beta users I am mainly aiming to find;

• Sales and Growth guys
• Small Business owners and/or Founders
• Event managers

How would you address the following groups and where would you find them?

P.S.: If you might be interested to try it, please drop me request via our support page: https://prospectrole.com/support/

I'll let you know once the beta is ready. Thank you!
