[Stable](https://zerogtalent.com/ai-companies/stable) provides virtual business addresses and AI-powered digital mailrooms for modern companies. Founded in 2019 and backed by Y Combinator (W20), the San Francisco-headquartered business digitizes physical mail and abstracts regulatory entity management requirements. Over 7,000 companies—including GitLab, Glassdoor, Indiegogo, and DoorDash—use the platform to receive physical mail, view scanned documents online, run automated mail workflows, and deposit checks.

To expand both its core software abstractions and its physical fulfillment infrastructure, the company is recruiting for roles including a remote [Product Engineer](https://zerogtalent.com/ai-jobs/stable/product-engineer-89669) and an onsite [Processing Center Specialist](https://zerogtalent.com/ai-jobs/stable/processing-center-specialist-86822) in Dallas.

## Building Digital Mail Infrastructure

Stable was co-founded by CEO [Sarah Ahmad](https://zerogtalent.com/people/sarah-ahmad) and CTO [Collin Pham](https://zerogtalent.com/people/collin-pham). The founders met as engineering students living on the same floor during their freshman year at Northwestern University. After building an early restaurant dish-recommendation app called Hot Plate at Northwestern's incubator and moving to San Francisco for tech careers, they teamed up in 2019 to launch Mistro, an international benefits platform for remote teams.

During their Y Combinator batch in early 2020, [Sarah Ahmad](https://zerogtalent.com/people/sarah-ahmad) and [Collin Pham](https://zerogtalent.com/people/collin-pham) noticed that distributed startups continuously struggled with physical address management and state government notifications. In an interview on YouTube with [SHAKTI VC](https://www.youtube.com/watch?v=rT0ykrBxzLU), [Sarah Ahmad](https://zerogtalent.com/people/sarah-ahmad) recalled how they launched an initial minimum viable product for Stable using Google Drive, Google Docs, Zoom onboarding calls, and Stripe links to manage physical mail for their first 100 customers before writing internal ops software.

## Physical Logistics and AI Workflows

Stable combines software engineering with physical ops facilities. Speaking on [Founders You Should Know](https://www.youtube.com/watch?v=XpeUpIe2Vok), co-founder [Collin Pham](https://zerogtalent.com/people/collin-pham) explained that US entity management regulations remain tied to 19th-century laws requiring physical addresses and paper delivery. To solve this, Stable operates processing centers—including a 10,000-square-foot facility in Dallas—where staff receive incoming mail, scan envelopes and internal documents, and handle physical inventory through custom fulfillment software.

The platform provides a customer-facing dashboard, internal mail operations software, and a public API that allows third-party tools to extract text from physical mail or integrate white-labeled virtual mailbox functions. As discussed on [SaaS Club](https://www.youtube.com/watch?v=KtXZ-g8Op-0), Stable incorporates AI to parse incoming documents, automatically route notices to specific team members, and extract payment data to sync check details into accounting software such as QuickBooks.

In a profile published by [Medium](https://medium.com/authority-magazine/the-new-ceo-playbook-sarah-ahmad-of-stable-on-balancing-purpose-profit-and-personal-brand-ab41b2530635), [Sarah Ahmad](https://zerogtalent.com/people/sarah-ahmad) noted that the company chose not to launch a consumer-facing virtual mailbox product, keeping its focus on business infrastructure and corporate entity management.
