When customer or company information sits across different records, identity resolution software can help identify which records may refer to the same entity. Compared on matching approach, household matching, and organization matching, these entries also distinguish between batch file import and real-time API access. Included records, free-plan availability, and paid-from pricing provide additional scope and cost details to weigh. Treasure AI Composable CDP, NVECTA, and Hightouch are among the options, alongside InterSystems IRIS and Splink. Consider which matching capabilities and data access methods align with the records and workflows you need to manage.
22 identity resolution software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
