Aporia

The founder and background

Aporia was founded in 2019, before the wave of large language models, and from the start it worked on machine learning models. The founder and CEO, Liran Hason, served in Unit 81 of the Israeli Military Intelligence Directorate and was a member of a team that won the Israel Defense Prize. According to Calcalist, he was one of the first employees at Adallom, the company founded by the founders of Wiz and acquired by Microsoft, and later joined the investment team at Vertex Ventures. Alon Gubkin served as CTO.

The problem: a model that worked in the lab changes in production

A machine learning model is tested before launch on certain data. Once it starts working with customers, the data changes: a different audience, a different season, a change in the product. The model keeps returning answers, but their quality can drop without anyone noticing. Aporia built a platform that tracks models in real time and alerts on changes in data, on bias and on drops in performance, and explains which factors influenced a particular decision of the model. In its acquisition announcement, the company listed Lemonade, DoorDash, Munich Re, Bosch and Sixt among its customers.

The move to generative AI

With the arrival of language models, the company expanded the product to a new kind of failure. According to Calcalist, the system detected hallucinations and security breaches in generative AI systems in real time, and could block a dangerous answer before it reached the user. Such mechanisms are called guardrails: a layer that sits between the model and the user and checks every answer, for example whether it is toxic, whether it contains leaked personal information, or whether the user is trying to get around the chatbot's settings.

Funding and the Coralogix acquisition

According to TechCrunch, Aporia raised about $30 million, most of it in a $25 million Series A in 2022, from investors such as Tiger Global, Samsung Next, TLV Partners and Vertex Ventures. In December 2024 it was acquired by Coralogix, an Israeli company that monitors software systems, in a cash-and-stock deal that the companies valued at about $50 million. Hason and Gubkin joined Coralogix to set up and run a new artificial intelligence research center.

What happened after the acquisition

In March 2025, Coralogix launched its AI Center, built on Aporia's technology. The product monitors artificial intelligence applications and looks for hallucinations, toxicity, data leaks and break-in attempts, alongside the software and infrastructure monitoring the company offered before. According to TechTarget, it also includes a catalog of AI use in the organization, guardrails, and measures of answer quality and cost. Hason was appointed vice president of artificial intelligence at Coralogix. The acquisition shows a trend in the field: monitoring AI systems has gone from a separate field to part of organizations' general monitoring tools.
