Yup. Version 1 fast and version 2 right. The problem is that normally feature requests a, b, c, and d come rolling in, and quality updates are postponed to version 3. Then, with a growing customer base, in comes half the alphabet in feature requests, and quality updates are postponed to version 4, 5, or 6.

I am not familiar with Apollo, but since you have a fairly specific customer profile, you could increase your network on LinkedIn, and then rather than cold-calling them, simply post content about how your product works. If interested, they will reach out to you.

Increasing your LinkedIn profile takes time, but you can automate part of that process with a tool like LinkedHelper. You basically provide a LinkedIn search URL and they will try to add all contacts in that list.
