Stable

Stable operates a business address and virtual mailbox service combined with a software platform for managing incoming physical mail. Customers select a premium street address that can be used for business registration, tax and IRS correspondence, and vendor communications, with support for multiple addresses. Mail sent to that address is received and processed at Stable's in-house facilities, scanned, and uploaded to the customer's online account, where it can be acted on remotely.

The platform applies AI to generate summaries of each mail item, automatically route mail to the correct recipient, and push extracted information into customers' other systems. It also monitors the customer's legal entity, flags due dates, and identifies urgent or time-sensitive actions. Additional capabilities include electronic check deposit, mail forwarding and shredding, shared team access with task assignment and activity tracking, a registered agent add-on, SSO, and integrations with tools including Zapier, Slack, HubSpot, Asana, Notion, Microsoft Teams, Google and Dropbox. A REST API supports searching and retrieving mail items and creating and onboarding locations via USPS Form 1583, alongside webhooks and self-service API key management.

Business model

Stable sells a subscription-style service combining a physical business address, mail digitization and processing performed at its own facilities, and access to its online mail management platform, with tiered plans that customers can upgrade or downgrade and add-ons such as registered agent service. It is positioned for customers ranging from startups and SMBs through scaling businesses to enterprises.
