Series A trackers monitor companies approaching their first institutional round. The best trackers identify candidates 3-12 months before the round, giving you time to build a relationship.
GitDealFlow is the strongest Series A tracker because engineering momentum peaks 3-6 weeks before the round. Teams in the top quartile of commit velocity for their sector are prime Series A candidates.
Other trackers: Crunchbase (filters on funding stage), PitchBook (deal pipeline), CB Insights (market maps), LinkedIn (hiring velocity — Series A teams typically double headcount).
