The Ghost in the K-1 Machine

A startup’s story does not end when the company is properly dissolved — its tax data keeps working, or failing, for years afterward. A well-documented loss is working capital that can recover a meaningful slice of the original check, but only if the right documents arrive on time. And the reason they often don’t is not any one person’s failure: private markets have no shared rails for moving K-1 data.


Sources: Sebastien Taveau with Dori Yona, “The Delivery Man” (Substack), on startup wind-downs and worthlessness documentation[cite: 8]. Loss-recovery figures are illustrative, depend on individual circumstances (including the tax characterization of the instrument held), and are not tax advice; readers should consult their own advisors[cite: 8].

About Author

Aaron Bartrim has spent his career at the intersection of technology and people, building systems that enable entire industries.
As CTO of Early Warning Services, he led the build-out of Zelle®, taking real-time payments from concept to a network serving more than 1,000 financial institutions, proving that speed and safety aren’t a trade-off when the system is designed for both. Earlier, as CTO of eFunds and a senior leader at FIS, he built the payments and integration infrastructure connecting banks to their customers. As CTO of Capital Markets Gateway, he brought that same discipline to equity capital markets, replacing decades of manual workflows with a connected digital platform.

Few technologists have taken an entire industry through that kind of change more than once. That experience of enablement at scale, done safely, is the lens he brings to AI: the next system industries will quietly depend on.

For fund administrators, accounting firms, and family offices with cross-border partnership exposure, schedule k-2 and k-3 are the most direct argument for automation in 2026. The schedules will not get simpler, and the work will only get bigger. The firms that build for that now will set the operational standard everyone else scrambles to match.
