Public prices involving Sunset
- Defunct companies' workplace data (Slack, email, Jira, documents) bought by the wind-down firm Sunset
Named press on a second wind-down firm's completed purchases, in a range Forbes calls similar to SimpleClosure's (not identical), sellers unnamed; Sunset's CEO Brendan Mahony prices on company size, age and how linked the data is, with premiums for healthcare and finance. The English original refuses scripted reads, so the Japanese edition Forbes licensed is quoted. Sunset buys rather than brokers, so these are prices paid to the closing company.

Pricing factors per CEO Brendan Mahony: company size, age and 'data richness' (internal traceability and cross-platform linkage). A Jira ticket tied to a specific code commit is worth more than a standalone document; healthcare and finance command a premium.
