Alesco Data is a US-based marketing data compiler founded in 2001 by Paul Theriot and headquartered in Fort Myers, Florida. Privately held and unfunded by outside investors, the company operates as part of The Alesco Group of Companies — a diversified marketing-services organization that also includes Statlistics and Response Solutions — spanning data management, brokerage, compilation, analytics and digital marketing. Employee-count estimates vary across sources from roughly 60 to just over 200, and the firm highlights an unusually long average staff tenure of 20+ years, reflecting a stable, family-oriented culture.
At its core, Alesco is a master compiler of direct-mail and digital audience data rather than a simple list broker. It builds and maintains proprietary consumer, B2B, automotive, resident/occupant, CPG, email and phone databases from hundreds of sources — public records, county recorder and tax assessor files, US Census data, directories, surveys and purchase transactions — and links records through a persistent identity graph for durable targeting. Its consumer file offers a household- and individual-level view with 300+ selectable attributes, its resident/occupant file covers 146M+ USPS delivery addresses for saturation mailings, and its automotive database reaches nearly 200 million auto owners (275M+ VINs with 183M+ opt-in emails), refreshed monthly and compiled outside state motor-vehicle records so it is not subject to the DPPA. Data accuracy is reinforced through monthly validation and a partnership with Truthset, the independent data-validation company.
On delivery and integration, Alesco supports omnichannel activation across direct mail, email and digital, with data made available for one-off purchase, monthly or yearly licensing, or usage-based pricing (ranging from roughly $20 per thousand records to about $250,000 for a full-database annual installation license, with free samples). Its automotive and audience data are integrated into the LiveRamp ecosystem for secure onboarding and distribution to major DSPs, and in early 2026 the company partnered with Databricks to make its third-party datasets discoverable on Databricks Marketplace via Delta Sharing. Alesco also layers in machine-learning analytics and identity-resolution services, serving marketing agencies, data resellers and brands ranging from Fortune 1000 companies to one-person operations. Note: employee counts, exact HQ suite address and revenue figures differ across third-party directories and should be confirmed directly with Alesco before publication.
