I think track record could just mean they've proven themselves in whatever field they've chosen. Ideally they've worked on early stage ventures in the past and had some level of success - but it could also mean they've made a name for themselves in the space they're working in. Maybe they're an influencer, etc. I think the idea is to answer the question "given their history, is it likely they'll be able to pull this off"
