What Upsolver does
Upsolver was a Palo Alto-based data infrastructure company founded in 2014 that built a real-time data streaming and Apache Iceberg optimization platform. Its core offering enabled enterprise data teams to construct continuous data pipelines for cloud data lakes using SQL and pipeline automation, with native support for the Apache Iceberg open table format and automated low-latency ingestion. The platform addressed pain points around complex data integration, processing latency, and the operational overhead of managing open lakehouse architectures for analytics and machine learning workloads.
The company operated a B2B enterprise software model, generating revenue through subscription-based licensing of its streaming and lakehouse optimization technology. Go-to-market relied on direct enterprise field sales targeting organizations with large-scale data engineering needs. Upsolver raised approximately $42 million across four funding rounds between 2015 and 2021, with investors including Scale Venture Partners, Vertex Ventures US, JVP, and Wing Venture Capital. The company maintained a leadership team of 51-100 employees led by co-founders Ori Rafael (CEO) and Yoni Eini (CTO).
In January 2025, Upsolver was acquired by Qlik, a strategic data analytics and integration platform operator. Post-acquisition, Upsolver's technology is integrated into Qlik's open lakehouse product portfolio, with distribution now handled through Qlik's global enterprise sales organization and partner network. The company's independent website redirects to Qlik's platform, indicating full operational absorption into the parent.
