Except for one. It came through a trusted contact, and he specifically wanted to intro me to a founder who had built a data security solution that he truly believed in. Out of respect for him, I took the video chat with the founder, and included my head of security on the call.
The founder's pitch was amazing, and I knew I wanted to use her product. She identified a problem that we definitely had, had built an elegant solution for it, and could demonstrate value very quickly in a 30 minute video call.
So if you want to get a VPE's attention, build something great but leverage someone in their network to warm up the intro for you. It works wonders.
We purchased her product within a month and implemented it within 2 weeks. It's now a core part of how we secured data internally.
