What is company funding rounds?
Company funding rounds is the historical record of an account's venture / growth-equity raises (Series A, B, C, etc.) with date + amount + lead investor. Crunchbase + PitchBook are the canonical sources; LinkedIn + press release scraping fill the gaps. The most actionable field is the most recent round date - a company that raised in the last 90 days is in spending mode.
When you're working from a lead email, the company funding rounds field becomes one of the most-requested enrichments because it lets you complete the buyer profile without forcing the prospect to fill another form. The trade-off is hit-rate: the company funding rounds value is only as findable as your lead email is unambiguous.
