What makes us different?

We are the world’s #1 AI-native Customer Experience and Marketing Platform. Our platform helps marketers build personalized journeys, grow their business, and work more efficiently — all in one tool.

We recently raised $500M in Series E funding, led by General Atlantic.

Over 1,200 global brands trust us — including Samsung, Coca-Cola, IKEA, Nike, and Virgin, as well as fast-growing startups. We’ve been recognized as a Leader by Forrester and IDC, and listed among G2’s Top 1% software companies in the world, ranking #1 in many categories like Customer Data Platforms, Personalization Engines, and Mobile Marketing.

But our story is not just about numbers! We are also proud of the global community we have built. With programs like SheCodes, SheLeads, and SheMarkables, we support education, sustainability, and inclusion across 27+ countries. At Insider One, we move fast, solve real problems, and build with purpose.
