Traditional identity resolution relies on deterministic matching — linking records that share an exact email or phone number — which fails when customers use multiple emails, old phone numbers, or inconsistent name spellings across loyalty programs, point-of-sale systems, e-commerce platforms, and call center records. Amperity's probabilistic ML models evaluate hundreds of attributes simultaneously to identify records that likely represent the same customer even without exact key matches, constructing a persistent customer identity graph that dramatically increases match rates compared to rules-based approaches. The unified customer profiles built on this identity foundation drive higher-quality audience segmentation, more accurate customer lifetime value models, and more effective personalization for paid media suppression and lookalike targeting. Amperity serves enterprise retailers, hospitality brands, and consumer companies including Alaska Airlines, Wyndham Hotels, Gap, and Under Armour that manage customer data spanning multiple brands, channels, and legacy systems. Founded in 2016, Amperity raised over $187M from investors including Tiger Global, Goldman Sachs, and Declaration Partners, competing with Reltio, Informatica, and LiveRamp in the customer data and identity resolution market. ## Frequently Asked Questions ### Why is probabilistic identity resolution better than deterministic matching for enterprise retailers? Deterministic matching only links records with identical fields like email or phone, missing customers who use different emails for different brand loyalties or whose records contain typos and inconsistencies. Amperity's probabilistic ML evaluates hundreds of attributes to identify likely matches, increasing customer coverage from 40-60% with deterministic methods to 80-95%, giving brands a far more complete view of their customer base. ### How does Amperity price its customer identity platform? Amperity uses enterprise contract pricing based on the scale of data processed and the number of platform modules licensed. It targets large enterprises and typically involves six-figure annual contracts. Implementation involves a professional services engagement given the complexity of enterprise identity resolution. ### Who are Amperity's primary customers? Amperity's customers are enterprise retailers, hospitality brands, and media companies — including Alaska Airlines, Starbucks, Wyndham, and Brooks Running. It targets organizations with large, fragmented customer databases across multiple systems that need unified customer identity to power personalization and measurement. ### What is Amperity's approach to customer identity resolution? Amperity uses a combination of deterministic matching (exact email/phone matches) and probabilistic ML models to connect customer records across loyalty systems, eCommerce platforms, POS, and CRM databases. Its patented approach builds confidence-scored identity clusters rather than forcing hard matches that create data errors. ### What data sources does Amperity ingest? Amperity ingests data from any source — Shopify, Salesforce, Snowflake, loyalty platforms, point-of-sale systems, CDPs, and flat files — using prebuilt connectors and a flexible schema-free ingestion layer. This breadth is critical for enterprise retailers with decades of legacy data in disparate systems. ### What analytics capabilities does Amperity provide beyond identity resolution? Amperity includes predictive analytics for customer lifetime value scoring, churn prediction, and product affinity modeling. These ML-powered scores are computed at the customer level and made available for audience segmentation and campaign targeting across activation channels. ### How does Amperity compare to LiveRamp and Acxiom for identity resolution? LiveRamp and Acxiom focus on third-party identity and data enrichment across advertiser networks; Amperity focuses on resolving a brand's own first-party customer data into a clean, unified profile. Amperity's value is enterprise-owned identity built from proprietary data, not third-party data augmentation. ### What activation integrations does Amperity support? Amperity connects to paid media platforms (Google, Meta, The Trade Desk), email service providers (Salesforce Marketing Cloud, Braze, Klaviyo), and data warehouses (Snowflake, BigQuery) for audience activation. Its AmpAi product uses the unified customer profile to generate ML audiences automatically. ## Tags martech, analytics, saas, b2b, enterprise, platform, ai-powered, data-warehouse, marketing --- *Data from geo.sig.ai Brand Intelligence Database.
