About
Non-market risk became a gating factor. The tooling did not follow.
The risk frameworks that institutional investors built over the last thirty years rested on a few assumptions: that legal regimes were broadly predictable, that reputational risk didn't really matter, and that last year's precedent still applied. Many of those assumptions are wrong today.
Meanwhile, deal timelines compressed. Roughly 90% of institutional M&A deals are now competitive, banker-led auctions. Legal and deal teams are being asked questions with real consequences and have no instrument calibrated to answer them at the speed the deal requires.
DEALSAGE exists to close that gap: a decision layer that weighs the legal, regulatory, geopolitical and other non-market signals together, and returns a view you can brainstorm with, and act on, in minutes.
Built by leaders from law, government, technology and institutional investing who lived this problem for decades.
