What PostGrid does

PostGrid Inc. is a privately held B2B SaaS company that operates a unified REST API platform for two related product lines: Print & Mail API, which automates the creation, printing, and physical delivery of personalized letters, postcards, checks, and self-mailers, and Address Verification API, which validates, standardizes, autocompletes, and geocodes postal addresses across the US, Canada, and 245+ countries and territories. The platform is hosted on Amazon Web Services and exposes a single API surface with sub-products for letters, postcards, checks, address autocomplete, lookup, standardization, geocoding, bulk verification (up to 200k addresses per batch), and 99.99% uptime. Ancillary tooling includes a built-in HTML editor, a PDF Wizard that uses OCR for document-to-address extraction, QR-code and Personalized URL (PURL) tracking, and a Template Gallery. PostGrid reports 171.5M addresses in its database with CASS, SERP, AMAS, and PAF certifications, and operates through 125+ print delivery partners.

The company runs a hybrid go-to-market combining product-led growth (free developer tier, test API keys, self-serve signup, Zapier integration spanning 1,600+ apps) with enterprise field sales ("Request a Demo," custom pricing, dedicated onboarding, account management). PostGrid is structured as PostGrid Inc., a US-incorporated entity, with country-specific branded domains and regional presence in the United States, Canada, the United Kingdom, and Australia. Its revenue mechanics combine usage-based pricing (per mailpiece and per address verification call) with subscription-style enterprise contracts; specific price points are not publicly disclosed. PostGrid holds HIPAA, SOC-2 Type II, PCI-DSS, PIPEDA, GDPR, and PHIPA certifications and reports a 2-business-day SLA.

PostGrid targets enterprise customers in regulated and high-volume verticals — healthcare, insurance, financial services, real estate, and retail/e-commerce — as well as internal teams in marketing, finance and billing, developers, compliance, and customer success. Named customers include Mutual of Omaha, Chubb, TransUnion, Equitable Life, Canada Life, BMW, Toyota, 3M, ADP, Omnicell, AccentCare, HelloFresh, Sephora, Louis Vuitton, University of Florida, University of Pittsburgh, RE/MAX, and Keller Williams. The company describes itself as serving 1,000+ customers and operates through native integrations with Salesforce, HubSpot, Marketo, Microsoft Dynamics 365, SAP, NetSuite, QuickBooks, Stripe, Braze, Klaviyo, and ActiveCampaign, among others. Headcount is in the "20+ Team Members" range per the careers page, and no funding rounds, acquisitions, or public listing have been disclosed in the source data.
