The Best Identity Resolution Software? Here’s How harpin AI Stacks Up

In today’s data-driven world, identity resolution isn’t just a backend data operation — it’s the foundation of how businesses engage customers, reduce risk, and unlock growth. But when identity data is fragmented or inaccurate, it causes more than just frustration — it drives up costs, slows decisions, and erodes trust.

This post breaks down what identity resolution is, why it’s so critical, and how harpin AI compares to other identity resolution providers based on performance, accuracy, and business value.

What Is Identity Resolution?

Identity resolution is the process of accurately matching and merging records that belong to the same person across disconnected systems. This could mean linking an email in your CRM with a loyalty number in your POS system, or matching a user’s support interaction to their marketing profile — even when the identifiers don’t match perfectly.

One of the most common challenges identity resolution addresses is duplicate records within a single system — for example, when a guest has two or more profiles due to typos, channel switching, or incomplete data. These duplicates can create serious problems: inflated customer counts, broken loyalty tracking, inaccurate lifetime value (LTV), and wasted outreach.

And the cost of not fixing them adds up fast. According to industry benchmarks:

• It costs $1 to verify a record at the point of entry
  
• $10 to fix it later
  
• And $100 if left unresolved — as downstream costs compound across support time, misfired campaigns, and lost revenue
  

Every duplicate record could cost you $10 or more just to resolve — and for large enterprises, that adds up to millions in preventable losses.

Done well, identity resolution results in a connected, trusted view of your customers. Done poorly, it creates confusion, inefficiencies, and missed opportunities at every level of the business.

Why Accurate Identity Resolution Is Essential

Customers interact with your brand across dozens of touchpoints. But behind the scenes, data often lives in silos: marketing platforms, customer support tools, ecommerce systems, booking engines, mobile apps, and more.

If those systems don’t agree on who a customer is, your team can’t either.

Bad identity resolution leads to:

• Duplicate communications or mistargeted ads
  
• Inaccurate segmentation or misclassified customers
  
• Compliance risks from mishandled personal data
  
• Support escalations due to incomplete profiles
  
• Misattributed revenue or churn data
  

In short: without accurate identity resolution, it’s nearly impossible to operate efficiently — or serve customers well.

Identity Resolution Use Cases (and Where the Pain Hits)

In Retail & Ecommerce

• Wasted spend from retargeting the same customer under different identities
  
• Abandoned carts misattributed due to cross-device behavior
  
• Offers sent to the wrong audience segment
  
• Loyalty program benefits not recognized or properly applied
  

In Hospitality

• Fragmented profiles mean VIP guests don’t get recognized
  
• Support teams spend more time resolving basic identity issues
  
• Inconsistent guest records across properties or brands
  
• Booking histories that can’t be tied to marketing campaigns
  

In Gaming

• Compliance headaches when identity data is incomplete or duplicated
  
• Player behavior fragmented across devices or accounts
  
• Poor user experience from login issues and misaligned engagement
  
• Lost revenue due to disconnected transaction and play data
  

The Benefits of Getting Identity Right

When you resolve identities accurately, the value compounds quickly:

• Higher Conversion Rates – Smarter targeting and better personalization
• Lower Support Costs – Agents have the full customer context at their fingertips
• Increased CLTV – Connected profiles allow for meaningful retention and upsell
• Stronger Compliance Posture – Consistent treatment of PII across systems
• Cleaner Analytics – Less noise and fewer misinterpretations

That’s why more teams are making identity resolution a top priority — and why the right tool matters.
