- M&A analysts and investment-banking teams
- Worth noticing
- The homepage reports 2,588 deals tracked, with coverage from November 2020; its recent-transactions section lists deals of $500 million and up.
Field notes
The displayed tables include transaction values, premiums, dates, and advisor names, alongside a software-comps sample with EV / Adj. EBITDA and EV / Revenue multiples. The site says its figures come from SEC filings, not from a market-wide transaction total, and notes that some values are calculated from price and shares when a filing does not state a deal value directly.
