Explorium, an Israeli tech startup that once reached a valuation of approximately $513 million, is ceasing operations after nearly nine years. The company's founders, Omer Har and Or Tamir, announced the decision on LinkedIn, marking the end for a firm that had previously garnered significant investor interest. Approximately 40 remaining employees are expected to lose their jobs.
Founded in 2017 by Maor Shlomo, Omer Har, and Or Tamir, Explorium developed a platform designed to help organizations locate external data and integrate it with their own information for machine learning, forecasting, and business decision-making. Over its lifespan, the company attracted substantial investments from venture capital firms and prominent tech investors, including Insight Partners, Oren Zeev, Vintage, Emerge, and F2. By 2021, Explorium had raised about $127 million, with a notable $75 million round that year valuing the company at $513 million.
In 2020, Explorium was recognized as one of Globes' most promising startups, and Shlomo was named to Forbes Israel's 30Under30 list. The company employed around 150 people at its peak but underwent significant changes in management and business focus. Shlomo stepped down as CEO in July 2023, with Har taking over. Shlomo subsequently founded Base44, an AI-driven app development platform.
Explorium attempted to adapt to rapid industry shifts and increasing AI competition by pivoting its focus. In 2025, it launched AgentSource, a data platform for AI agents in marketing and sales, and Vibe Prospecting, an AI-powered lead generation tool that reportedly reached over 350,000 registered users. Despite these efforts and reported growth in the past year, the company ultimately could not achieve the necessary stability to continue operating.
"Despite an exceptional team, we acted quickly in a market that underwent significant upheaval, and we continued to grow in the past year. Ultimately, we are sad to say that all of this simply wasn't enough," the founders stated in their announcement. Har described the decision to close as the most difficult he has had to make, though he believes it is the right step at this time. AgentSource is scheduled to shut down on December 2, 2026, with remaining unused balances to be refunded to customers.
