A surprising (to us) takeaway was that making a product in this space sound "vanilla"/undifferentiated is a good thing. Once folks aren't concerned about an initial integration being a lift, they're happy to onboard us as "just another trading venue" (but with great story about unique liquidity and match quality). Many then get excited about adopting the lowest hanging fruit incrementally for their specific use cases. And after peeling away a few layers of the onion, they get excited about the future state in which others do the same, and what initially seems like incremental change becomes a market structure transformation.
We studied the history of adoption in other markets where it's gone well (FCC spectrum, display advertising, procurement) and poorly (OptiMark, POSIT4—great attempts, ahead of their time, killed by complexity and subtle mismatches between the mechanism and market participant needs).
