What We Do

Dataminr -- long recognized as one of the world’s leading artificial intelligence (AI) startups -- puts real-time AI and public data to work for our customers, generating relevant and actionable alerts for thousands of users working in more than 100 countries for hundreds of client organizations--spanning global corporations, public sector agencies, NGOs, and newsrooms. As 2020 taught us, the unexpected can occur anywhere, at any time, radically affecting the health and safety of people and business operations. Real-time data is crucial for enhancing organizational agility, sustaining business continuity, and responding with speed and confidence. This is especially true as the landscape of public data sources expands and diversifies, spanning social media, information sensors, blogs, and the deep web. Dataminr processes billions of data units daily from 100,000+ public information sources in 100+ languages and in multiple formats -- including text, images, video, sound, and public sensor data. We use many different AI/ML techniques and methods such as natural language processing, understanding, and generation; computer vision; audio processing and classification, and anomaly detection on machine-generated data streams. Dataminr continuously trains its AI models on an accumulated 10-year archive of trillions of public data units and over 100 million critical local, national and global events while the company’s numerous AI models are all built, trained, and continuously updated by a team of data scientists, engineers, and researchers. In alignment with our belief that AI and real-time data should be a force for good, we forged a partnership with the United Nations in 2019, at the AI for Good Summit in Geneva. The partnership equips thousands of UN personnel with Dataminr’s First Alert. The initiative boosts the UN’s utilization of cutting-edge technology and provides their agencies and personnel with the earliest possible indications of emerging crises, accelerating humanitarian response efforts around the world. Since 2009, Dataminr has brought to market products that our clients find essential to make better-informed decisions, and effectively respond with speed and confidence to risks and opportunities.

Why Work With Us

At Dataminr, we’ve fostered a people-first culture. Seeing the incredible impact of our customers ‘knowing first, and acting faster’ is the main reason why over 90% of our employees said that they're proud to work at Dataminr. Join the team and help the world manage risk in real-time along with 1,000+ talented people across seven offices!
