Ask HN: How do I improve this business?

I recently bought FundedList (https://www.fundedlist.com).

We provide contact information on recently funded startups (CXO email, linkedin, funding data etc.).

If you are a potential customer -- how do I make this service more valuable? More personalized info? Help draft cold emails? Something else?

I only have a handful of customers, so I'm looking for broader feedback.

P.S. Elephant in the room -- this may receive negative attention, given (cold) email marketing can be considered spammy. However, I have been on the receiving end of very good cold emails that led to productive business relationships. I have also sent such emails. To be clear, I believe this sort of service is valuable, if used right.
