In their own words
Keelstar
Keelstar provides monitored workflows for collecting, approving, monitoring, and auditing business documents, including W-9s, insurance certificates, contracts, invoices, and policy acknowledgments. Its applications cover vendor compliance, contract operations, HR compliance, finance operations, and shared platform auditing. Applications share audit logging, permissions, notifications, and exports, and every workflow supports exporting records with their full history. Free browser tools provide one-time results without an account and can be upgraded to monitored workflows. Keelstar describes setup as self-serve, with same-day go-live and no implementation fees or rollout project. The Free tools plan costs nothing; Team costs $49 a month per workflow and includes one monitored application and up to 10 seats. Business pricing is custom and not listed. Keelstar says data is encrypted in transit and at rest, customers can export it or request deletion, and it does not sell customer data. The API describes endpoints for documents, parsed fields, workflows, monitors, notifications, and webhooks.
