Why it matters
Blackletter is testing whether a law firm can keep clients through accumulated matter context and fixed pricing instead of partner relationships and billable hours. If the model holds, the buyer gets finished legal work at a quoted price while the firm keeps the margin from its own software, a structure Crosby's $400 million valuation suggests investors already take seriously.

Blackletter, a Canadian law firm built around proprietary AI software and fixed fees, announced a $6 million seed round on November 9th led by Lerer Hippeau. Jonathan Rosenbluth (@jrbluth), Blackletter's co-founder and chief executive, announced the round in a thread on X and told Business Insider the firm combines technology and lawyers to sell legal services for flat fees.
