Qohash provides data security software that discovers, tracks, and protects sensitive information across cloud and on‑prem environments. Its core tools are Recon, which scans for sensitive data (PII, intellectual property, and other critical data) and returns results up to 10x faster than traditional tools, and Qostodian, which tracks how data elements move and are accessed or shared within an organization. The company targets regulated industries such as financial services, government, healthcare, and technology, and operates on a subscription model complemented by consulting services to help implement and optimize data security strategies. Differences from competitors include speed of data discovery and proactive data movement visibility across environments. The goal is to help organizations comply with strict data protection regulations and improve data privacy and security by providing clear visibility and control over sensitive data.

What believers are saying

  • TELUS integrated Qohash into Fuel iX on September 16, 2026, expanding enterprise distribution.
  • Qostodian Nexus launched September 16, 2026, targeting banks, defense, and regulated European buyers.
  • Mila partnership opens talent, research credibility, and product feedback for 2027 commercialization.

What critics are saying

  • Microsoft Purview, Netskope, and Wiz can bundle adjacent controls, compressing Qohash's pricing quickly.
  • If TELUS stalls or displaces the integration, Qohash loses its clearest enterprise channel.
  • Qostodian Nexus must convert 2026 buzz into 2027 revenue; otherwise Series B capital runs out.

What makes Qohash unique

  • Qostodian Nexus inspects prompts and tool calls in customer environments, never exporting data.
  • Qohash owns patented edge data security IP, designed and researched entirely in Canada.
  • Its platform tracks individual sensitive elements, not just files, across AI and enterprise workflows.

Qohash launches a tool to protect sensitive data from AI.

Qohash launches a tool to protect sensitive data from AI. Jean Le Bouthillier, founder and CEO of Qohash. (Photo: Emmanuel Martinez) Quebec start-up Qohash launches a tool that allows organizations to adopt artificial intelligence (AI) without putting their sensitive information at risk Called Qostodian Nexus, this technology, unveiled Wednesday at the All In AI conference in Montreal, recognizes sensitive data as it flows between employees, AI agents and language models, then decides how to handle it, even before AI has access to it. It therefore helps avoid an unfortunate data leak to AI, as can happen when formulating a query ("prompt"), when uploading files, or when AI agents interact with external systems or perform other functions. "If there is sensitive data, we will be able to identify it, block it and redact it," specifies Jean Le Bouthillier, founder and CEO of Qohash. "We can monitor AI agents in real time." Another advantage of this solution is that content inspection happens in real time inside the client's environment, so nothing leaves it to be analyzed. "This will allow companies to deploy their AI tool more quickly, estimates the head of Qohash. There is a lot of pressure to adopt AI, but it increases the risks of data leaks." Listening to clients. For the company specializing in data security, this is the most important launch in its history since its founding in 2018 and a shift toward another area beyond compliance and data control. "With the enthusiasm for AI, we think this tool will generate a lot of sales," maintains the head. He specifies that it was after speaking with many clients that he had the idea to tackle this solution. "It was market demand that forced us to go in this direction," he mentions. The clients the young company targets are large players with more than 5,000 employees who have high volumes of data to process and cannot afford to have any escape from their infrastructures. "We are targeting banks and financial services, telecommunications and defense supply chain companies," says the executive. "They have a lot of sensitive data and intellectual property to protect." Qohash wants to sell this product in Canada, the United States and Europe, particularly in Germany. The positive effects should be felt in 2027 on the company's balance sheet. "It is our main growth tool for the coming years," maintains the head of the start-up, who is counting on support from the Fonds de solidarité FTQ, Desjardins Capital and Export Development Canada. With Telus. Qostodian Nexus was created in partnership with Telus, a fruitful association, according to Jean Le Bouthillier. "We collaborate with them to understand the problems, and, when the prototypes were ready, to work at scale," he affirms. "The intellectual property remains ours." Chris Madan, vice-president, digital solutions for customers and products, at Telus, notes on his side that this co-creation exercise allowed his teams to learn more about innovative elements for securing AI. "It is an excellent technology," says the man who considers it essential to work with local start-ups to create Canadian solutions. He adds that what happens to sensitive data when it enters an AI system is one of the most crucial problems facing companies, so he is proud that Telus participated in developing a technology that solves this problem. Isabelle Turcotte, co-founder and chief executive officer of All In, also highlighted the importance of this new product. "It is exactly the type of local innovation we need to build a strong and competitive Canadian AI industry," she says in a press release. "The adoption of AI can only truly grow if organizations can trust the systems and data that support it," she continues, emphasizing that cybersecurity is one of the essential conditions for the spread of AI. In addition, Qohash also announced Wednesday a new partnership with Mila, the Quebec AI Institute. With this agreement aimed at strengthening exchanges between the research community and industry, the Quebec start-up will have access to Mila's network of experts, as well as to skills development and knowledge-sharing activities.
