I'd start by thinking about what I could do to help the people on the list. So for example you've got 2 groups (startups and people who want to work at one) that would benefit from being introduced. So I'd start by appending data as needed to drill down to find 10 or so people who would most benefit from your help. Maybe that's connecting people with tech skills who live outside of a tech hub but would consider moving with startups that will pay for relocation. Then I'd reach out personally and help those 10 people find the perfect startup. Then repeat/pivot/automate.
