What Trestle does
Trestle Solutions, Inc. is a Bellevue, Washington-based identity data company founded in 2022 that operates an API-first platform for validating, verifying, and enriching contact data. Its product portfolio centers on phone intelligence (Reverse Phone API, Phone Validation API, Caller Identification API, Smart CNAM API), contact verification (Real Contact API, Reverse Address API, Address Validation API, Find Person API), and risk decisioning (Decision Console for manual review and Decision Signals API for automated decisioning), supplemented by add-ons including Litigator Check, Spam Check, Email Deliverability, and Email Age Score. The underlying platform is built on a proprietary database of 190 million verified phone numbers refreshed on a monthly cadence, supports 500+ million monthly queries with a 99.99% uptime SLA, and serves 2 billion+ queries annually. Machine learning techniques generate activity scores, A-F contact grades, email age signals, and identity risk weighting, while a Phone Feedback API closes a data contribution loop with high-volume customers.
Trestle monetizes through three coordinated streams: per-query API usage fees billed against a self-serve wallet (funds expire after one year), annual subscriptions with committed query volumes or seat licenses for enterprise customers, and per-seat licensing prorated by billing period. Distribution is hybrid: a self-serve developer portal with free trial and sandbox environments captures the SMB/long-tail, while enterprise field sales handle committed-volume contracts. Distribution is amplified through marketplace and partner integrations including HubSpot (native app), ZoomInfo, Make.com, Databar.ai, Apollo, and GoHighLevel, and a strategic partnership with RocketReach that embeds Trestle's grading into a major sales-intelligence platform at scale.
Trestle serves sales, recruiting, and marketing operations teams as the primary segment (B2B contact data, lead verification, outbound dialing optimization), with adjacent use cases in eCommerce (fraud prevention), insurance (policyholder and claims validation), lead generation (contact quality scoring), real estate (tenant and property screening), and communications service providers including AI voice agent platforms. The company maintains documented GDPR and CCPA compliance with EU SCCs and is pursuing SOC 2 Type II certification with role-based access controls introduced in late 2024.
