Last quarter Legora and WRITER joined Notion, Rogo, Ramp and Polymarket as Teleskope customers. Together the six are valued at more than $100 billion, and five of them are on the 2026 Forbes AI 50, CNBC Disruptor 50 or Forbes Fintech 50. They chose Teleskope because it's the only data security platform built for machine speed.
Data security is what's blocking AI
Every company we talk to is in one of two places with AI. Some have it turned off: they can't roll out Copilot, Claude or their own agents until they know what sensitive data those tools will surface. Others, like the six on this list, turned AI on first and need security that keeps up without slowing them down. Either way, data security is what stands between them and AI.
We hear this from prospects all the time. When teams tell us why their data security project suddenly became urgent, most point to an AI or Copilot rollout that surfaced overshared and legacy data. The oversharing was always there. AI made it findable.
The defenders' window for data
Greg Brockman calls it the defender's window: a short stretch where the people defending have a head start on attackers who will soon have the same AI. An open letter signed by more than 100 organizations, including OpenAI, Anthropic, Google and Microsoft, makes the same point about a limited window. I want to borrow the idea and apply it to the place every attack ends.
Every AI attack is ultimately after the data. Breaking in is just the way to get to the credentials, customer records and internal documents a company holds. The defenders' window for data is the head start you have to find and fix exposed data before an attacker's agent gets to it. If the data is already secured, an attacker who gets in has far less to take. Your vulnerabilities are now instantly exploitable. With Teleskope, they're instantly resolved.
A better DSPM won't fix this
I spent years as a security engineer at Airbnb watching risks pile up faster than anyone could close them. Our tools were good at showing us problems. They left the fixing to people, and there were never enough people.
Legacy DSPM and DLP still work that way. They find risk and hand it to a person, which assumed data moved at human speed. Now people and their AI tools create, copy and share data in seconds across Slack, shared docs, SaaS apps and assistants. Every scan returns a longer list, and nobody has time to work a dashboard. Showing a team more problems doesn't help. They need the problems fixed.
The AI data security analyst
Teleskope is the AI data security analyst: agents that find and fix risk at machine speed. They do the work of a data security team, finding sensitive data, deciding what should happen to it based on your policies, and fixing it in seconds.
Under the hood, our Data Reasoning Layer understands what data you have and the business context around it, decides what should happen, and enforces that decision natively across SaaS, cloud, on-prem and AI tools. Every action stays within your policy, with blast radius limits, rollback and an audit trail. Your team sets the rules. Our agents do the work.
Kosmo, our data security agent, is now generally available. It turns your policies into classification, ranks what to fix first by Risk Score, carries out the fixes your team approves, and reports on the risk it removed.
What it looks like in practice
Ramp is the clearest example. Teleskope fixes sensitive data in Ramp's Slack within a two-second SLA, 100% of their remediation workflows run automatically, and their security team spends about an hour a week managing more than 40 policies across Slack and Google Workspace. They aren't working a queue. They set the policy and our agents handle the rest.
Eric Freeman, CISO at WRITER, put it this way: "Enterprises adopt WRITER because they trust us with their data. Teleskope helps us earn that trust at machine speed, finding and fixing real risk automatically so security never slows down the business."
Every one of these six companies is built on sensitive data. Legora handles legal work, WRITER handles enterprise content, Notion holds company knowledge, Rogo runs financial analysis, Ramp manages corporate spend and Polymarket runs prediction markets. For all of them, keeping that data safe is part of the product.
Turn AI on safely, today
Security teams have been told for years that they have to pick between moving fast and staying safe. The companies on this list didn't pick. Their data moves in seconds, and a control that waits on a ticket is already too late. Teleskope is the data security layer that lets you turn AI on safely, today.
