Snowflake turns the data cloud into the agent control plane
A 34% revenue print, a $6B AWS pact and the Natoma deal reframe the lakehouse as the governance layer for enterprise AI agents..
Snowflake is a data warehouse in the cloud: a place where large companies dump every transaction, log file and CRM record so analysts can query it. The new twist is that those queries are no longer just typed by humans. AI agents are starting to read the data, write to it, and call other software tools on a company’s behalf. That raises an awkward question: who let the agent in, and what is it allowed to touch? Snowflake spent its May 27 earnings day answering it. It posted record growth, committed $6 billion to Amazon’s cloud over five years, and bought a small startup called Natoma whose job is to police what AI agents are permitted to do. The pitch to enterprise buyers: if your data already lives in Snowflake, so should the guard rails for the agents acting on it.
On a video link from Snowflake’s Menlo Park headquarters, CEO Sridhar Ramaswamy walked analysts through a quarter he framed as a turning point. “Our platform brings together the four elements organizations need to become an agent enterprise,” he told them, ticking off “a unified governed data foundation, access to leading AI models, connectivity across enterprise applications and workflows, and a unifying agent control plane that turns intent into governed action.” He called it a “clear inflection point” in the company’s AI journey. The market took him at his word. Snowflake shares jumped roughly 36% the next trading day, the sharpest single-session move since the company’s 2020 debut. The numbers underneath were genuinely strong. Product revenue reached $1.334 billion, up 34% year-over-year and accelerating 400 basis points from Q4. Remaining performance obligations — the contracted backlog — swelled to $9.21 billion, up 38%. Net revenue retention ticked up to 126%, the first uptick after five flat quarters. Snowflake added 616 net new customers, the most in any fiscal first quarter in its history. Management raised full-year FY27 product revenue guidance to $5.84 billion, implying 31% growth versus the 27% guide it had set in March. But the headline was not the beat. It was what Ramaswamy bundled with it. Snowflake disclosed a five-year, $6 billion commitment to AWS, covering Graviton CPUs, GPU capacity for AI inference, and joint go-to-market spend. That comes on top of more than $7 billion in lifetime sales Snowflake has already routed through the AWS Marketplace, with $2 billion of that booked in calendar 2025 alone. For Amazon, it is a vote of confidence at a moment when hyperscaler customers are openly hedging between clouds. The second announcement was the more strategically interesting one. Snowflake said it had signed a definitive agreement to acquire Natoma, a two-year-old San Francisco startup founded by Pratyus Patnaik, Will Potter, Zachary Hart and Paresh Bhaya. Natoma builds what is, in plain terms, a bouncer for AI agents: a centralized gateway that sits in front of Model Context Protocol (MCP) servers and enforces identity, policy and audit at the level of every individual tool call. When an agent asks to read a Salesforce record or push a row into NetSuite, Natoma decides whether the human behind it had the right to do that, logs the request, and produces an evidence trail. The Register, less reverent than most outlets, summed it up as Snowflake buying Natoma “to help freeze out rogue agents.” That is closer to the operational truth than the marketing language. Terms were not disclosed.
To see why this matters, it helps to understand what MCP is and is not. The Model Context Protocol, originally drafted by Anthropic in late 2024 and since handed to the Linux Foundation, is a thin standard for exposing tools and data to a language model. It looks deceptively like a USB-C port for AI agents: plug in a CRM, a database, a Jira instance, and the model can call them through a uniform interface. The trouble is that the specification itself does not enforce security. Authentication, authorization, rate limits, audit logging — all of that is left to whoever runs the server. A recent arXiv survey of MCP risks lists prompt-injection routes, tool poisoning, token aggregation and shadow servers as the four most common failure modes. That is the gap Natoma fills, and it is the gap Snowflake is now claiming as its own. The acquired platform becomes the chokepoint between Cortex Agents, Snowflake Intelligence and Cortex Code on one side, and the long tail of enterprise SaaS, on-prem systems and APIs on the other. Every tool call passes through a verified library of MCP servers; every action is checked against the identity of the human ultimately on the hook for it. Architecturally, this completes a stack Snowflake has been quietly assembling for eighteen months. Horizon Catalog provides the metadata layer — lineage, tags, masking policies, classification. Cortex Agents provides the reasoning loop. Snowflake Intelligence and Cortex Code sit on top as the user-facing products. Natoma slots in as the policy enforcement plane between agents and the world outside the warehouse. Crucially, it brings the governance perimeter with it: an agent invoking a tool inherits the row-access policies and dynamic masking rules already defined in Snowflake’s RBAC model. The same controls a DAX40 data engineer wrote for a human analyst now apply to an agent acting on that analyst’s behalf. The competitive geometry is unmistakable. Databricks has been building a parallel stack around Unity Catalog and Genie. Microsoft is pushing Fabric and Copilot Studio toward the same outcome. SAP, ServiceNow and Salesforce all want to own the agent layer over their respective application estates. What is unusual about Snowflake’s move is the explicit bet that governance, not orchestration, is the bottleneck. Ramaswamy did not buy an agent framework. He bought a permission system. There is a historical rhyme here. In 2014, AWS acquired a tiny startup called Annapurna Labs for what was then read as a curious silicon play. It became the foundation for Graviton, Nitro and arguably the modern hyperscaler economics. Natoma is a smaller cheque against a similar bet: that the boring infrastructure piece nobody is excited about today will end up shaping who collects the rent tomorrow. The five-year, $1.2 billion-a-year AWS commitment is the matching wager on the compute side.
For DAX40 CIOs running Snowflake at material scale — Siemens, whose enterprise data mesh is built on the platform, alongside the BMW, Allianz, BASF, Munich Re and Bosch data estates that already route significant workloads through it — the practical question shifts from “which agent framework” to “which governance perimeter.” If Cortex Agents can act on customer or claims data using the same row-access policies a Frankfurt risk team wrote five years ago for human analysts, the cost of getting an agentic pilot into production drops sharply. The harder question is whether existing IAM investments — Okta, Entra ID, SAP IPS — will federate cleanly into Natoma without doubling the audit surface. Procurement teams should also note the AWS commitment: it signals continued multi-region build-out in Frankfurt and Zurich, which matters for data-residency clauses.
The EU AI Act reaches full applicability on 2 August 2026, roughly nine weeks after this announcement — though Brussels has just deferred most of the high-risk regime to December 2027 under the Digital Omnibus. Either way, documented risk management, automatic logging, human oversight, and technical documentation land squarely on systems that screen employment candidates, set credit scores, or take consequential action on critical infrastructure. An MCP gateway that records the full chain from user to agent to tool to upstream system is, conveniently, exactly the evidence trail Article 12 and Annex IV ask for. That is the regulatory tailwind Snowflake is implicitly pricing in. BaFin and the Bundesnetzagentur will, however, want to see whether Natoma’s policy engine can express controls in terms a German DPO can actually audit. Fines run up to €35 million or 7% of global turnover.
Natoma raised a Series A from Andreessen Horowitz, Sequoia-adjacent angels and operator funds barely twelve months before the sale. The implied multiple, while undisclosed, will reinforce the thesis that MCP-adjacent infrastructure is a fast-exit category: build a thin governance, identity or observability layer on top of the protocol, sell to a hyperscaler or data platform within eighteen months. Expect a wave of seed rounds into MCP gateways, prompt firewalls and agent observability before year-end. The flip side: founders building in this space now face a closing window before Microsoft, Databricks, Salesforce and Google ship native equivalents. The Salesforce Agentforce, Google ADK and Databricks Genie roadmaps all converge on the same surface area.
