Deep Sync

What Deep Sync does

Deep Sync is a U.S.-headquartered (Kirkland, WA) data and identity resolution company that emerged in 2022 from the consolidation of seven legacy data firms including AccuData, Compact Information Systems, HomeData, and ASL Marketing. Its core technology is a deterministic identity graph built on a direct-mail-grade truth set covering approximately 260+ million U.S. consumers (96-97% of the population), linking billions of online identifiers (hashed emails, mobile ad IDs, IP addresses, UID2s) to known individuals and households with weekly updates from USPS change-of-address data. Deep Sync is one of only two companies with direct national-scale USPS data access.

The company monetizes through four streams: (1) one-time data licensing of residential, consumer, business, mover, and student datasets; (2) recurring install licenses for large-volume marketers receiving scheduled file drops; (3) usage-based access via Deep Sync One, a self-service audience-building platform with 200,000+ segments and direct integrations with Meta, TikTok, The Trade Desk, and Google DV360; and (4) professional services for data hygiene, enhancement, profiling, and identity resolution, available through direct sales and cloud marketplaces. Cloud-native listings on Snowflake (Elite Partner status) and Databricks enable enterprise "data-in-place" workflows, and ecosystem partnerships with LiveRamp, Oracle Advertising, MNTN, and MadHive extend reach to 700+ activation destinations.

Deep Sync serves agencies, brand marketers, programmatic ad buyers and sellers, reseller partners (printers, mail houses), and verticals including financial services, retail, insurance, home services, education, telecom, automotive, and political campaigns. Named logos include T-Mobile, multi-unit regional financial institutions, national auto club partnerships, and enterprise retailers. The company employs 51-100 people, is privately held with no disclosed external venture funding beyond a 2024 accelerator-context $0 round (100Unicorns, Dominor Investment), and maintains SOC 2 Type II and CCPA compliance.
