“We’re finding connections in our data where there are no unique identifiers. Without the power of Amperity’s algorithms, those connections would remain hidden and the data would go to waste.”

Michael Relich (fmr.) COO Lucky Brand

Data is messy, and traditional identity resolution methods don’t address the root cause

Customer data will always be messy

Customers provide businesses with a wealth of information, but their Personal Identifiable Information (PII) is often inaccurate because it’s scattered across systems that don't talk to each other. Connecting that data uncovers a world of insight and opportunity.

Many customers are anonymous

Your best customers don’t always identify themselves when they interact with your brand and even brands’ with strong loyalty programs struggle with bringing known customers on board.

Investments in data are expensive & often lacking

Digital transformations require massive investments in infrastructure, storage, SAAS platforms, and data scientists, but even with the substantial resources, 87% of efforts fail.

Traditional identity resolution is limited

Deterministic matching alone is insufficient, leading to misidentified customers, suboptimal insights, and missed opportunities.

Deterministic-only approaches can erode data quality

Rigid, rules-based approaches to matching data cannot account for less than perfect matches and can lead to duplicate records and incorrect merges.

Amperity combines over 45 identity resolution algorithms

Amperity's multi-patented, AI-powered approach resolves identities accurately and holistically on a daily basis, unifying records that other approaches routinely over- and under-connect.
