About us

Insider One is the #1 platform that brings everything marketing and customer engagement teams need in one place so they can reach their peak potential and become unstoppable.

Our story began with six desks and a vision to create a single platform to make industry-first technologies and emerging channels accessible to marketers worldwide. Today, Insider One is powered by 1,500+ team members representing 50+ nationalities across 30+ offices. With AI at its core and an integrated Customer Data Platform (CDP), Insider One unites data, personalization, and journey orchestration across the most extensive set of natively supported channels, including WhatsApp, SMS, Email, Web, App, and Site Search.

We recently raised one of the largest funding rounds in the industry, a $500M Series E led by General Atlantic. We are backed by top-notch investors, including Sequoia Capital, QIA, Riverwood, and Endeavor Catalyst, and trusted by 2000+ customers from high-growth startups to the most prestigious Fortune 500 companies such as Samsung, Nike, L’Oreal, Singapore Airlines, Nestlé, Nissan, Lenovo, Puma, IKEA, Allianz, Domino's, and the list goes on.

Insider One was congratulated for becoming one of the only woman-founded, women-led B2B SaaS unicorns in the world. Loved by customers, recognized by analysts, we are the only vendor recognized as the #1 leader in all the capabilities marketing and customer engagement teams need. Don’t just take our word for it — see for yourself. We consistently outperform and continue our leadership, and the results speak for themselves.

From day one, Insider One’s mission has not only been to build a world-class product company, but also to create one of the most socially progressive technology communities in the world. Through our social responsibility initiatives like 100 Social Responsibility Projects, AI Training for Teachers, Code Academy, SheCodes, SheLeads, and SheMarkables, our community has committed to scaling its impact on our communities across 30+ countries, driving initiatives in health, education, farming, animal rights, and increasing women’s representation in STEM.

Behind all these achievements is an exceptionally talented, visionary team of overachievers that moves fast and agile, creating cutting-edge products, and focuses on making an impact. If you want to be a part of this journey, just keep reading.

What are you looking for? A regular traditional company? A fun working environment? Well, we do have a fun working environment and some other traditional stuff that you would expect from any normal company. But are they really what you are looking for? Or are you looking for somewhere where you can actually do something and create an impact? Be part of a bigger purpose? Become something real, someone real. Startups are the art of the possible if you are a “real” believer, a learner, a challenger, a giver looking forward to betting on yourself, going out there, and conquering the world with your dedication and hard work. As the Finance & Business Support Team, we are not a cog in the wheel in Insider One but the builders of the wheels.
