Last Mile Complexity Favors Narrow Automation
Lassie
The core lesson is that broad healthcare automation breaks on the last mile of payer and provider workflows. A bot can log in and move data, but each carrier has different portals, claim status rules, enrollment steps, remittance files, and exception paths, so scale depends less on generic automation and more on endless workflow-by-workflow maintenance. Olive's shutdown in 2023, after selling units to Waystar and Humata, showed how costly that complexity can become.

In payment posting and reconciliation, the hard part is not reading a remittance once, it is matching each ERA or paper EOB to the right claim, adjustment code, and patient balance, then writing it back correctly into the billing system. That is why products in this layer sell accuracy and exception handling, not just automation rate.

Olive tried to automate across many hospital back office jobs at once. More focused vendors now attack narrower tasks such as claims follow up, eligibility, prior auth, or payment posting, where they can train around a smaller set of payer behaviors and keep humans in the loop on edge cases.

For Lassie, this makes cross-payer normalization the product. If it can absorb messy payer behavior across specialties and practice systems, it becomes valuable precisely because embedded PMS or payment vendors are usually strongest inside their own software and weaker at handling fragmented workflows outside it.
The market is moving toward narrower, deeply integrated automation products that replace specific manual queues first, then expand outward. Winners in healthcare infrastructure will look less like horizontal AI layers and more like specialized operators that turn broken payer data and remittance workflows into reliable system of record updates.
