The product
What AIR is building
AIR sits inline between an agent and everything the agent reads. The framing on their own site is precise: "AIR sits between agents and the outside world. It continuously analyzes and filters every input into an agent's context — from skills, MCPs, and plugins to websites and internal data — stopping threats before they reach the agent." The insight is that the attack surface of an agent is not the model, it's the supply chain of things you bolt onto the model. The product decomposes into four pieces. AIR Control does fleet governance: find every agent actually running inside a company, including the ones nobody registered. AIR Filter is the vetting firewall over the three add-on primitives that matter right now — Skills (reusable task instructions), MCP servers (external capabilities), and plugins (bundles of both). AIR Defend handles runtime protection and threat detection once an agent is live. AIR Marketplace is the endgame: a source of pre-vetted add-ons, so the enterprise default becomes an allowlist rather than a scramble. The numbers behind the thesis come from their own scanning work. AIR says more than 17,800 public AI add-ons, carrying roughly 6.7 million installations, depend on untrusted external sources, and its whitelist currently filters out about 27% of available skills and add-ons as risky. They found fake Skills impersonating Anthropic and OpenAI that could execute arbitrary code. That is a package-registry problem wearing new clothes, and nobody has shipped npm-audit for agents yet. Demand so far is concentrated in financial services and pharmaceuticals, which is exactly where you would expect it: regulated industries that want agents in production but cannot sign off on an unbounded set of third-party tool calls.
The money
Why this matters
Every serious enterprise agent deployment in 2026 runs on an add-on layer that resembles the early npm ecosystem: open publishing, no provenance, transitive dependencies, and installation counts in the millions. AIR's own scan puts 17,800+ public add-ons with ~6.7M installs on untrusted external sources, and 27% of what they see fails their bar. Those are the founders' figures, not an industry survey, but they match what the OWASP Agentic Skills Top 10 was created to catalogue, and Niv Hoffman co-leads that project. The timing argument is that the security layer for agents gets bought before the agents themselves get fully trusted, not after. Sequoia wrote a $10M check and Greenoaks wrote $40M within weeks of each other into a company founded in February. That is not patience, that's a land grab for a category the buyers are already asking about. Twenty-plus customers inside six months, with roughly a quarter of them large enterprises, says the pull is real rather than manufactured.
Investors: Sequoia (led the $10M first round), Greenoaks (led the $40M second round), Swish Ventures, Netz, Angels: Zach Frankel (President, Cognition), Yinon Costica (Co-founder, Wiz), Ofir Ehrlich (Co-founder, Eon), Anne Neuberger, Omer Adam, Varun Anand (Co-founder, Clay)
The outlook
Hiring outlook
Explicit and specific. AIR says it is expanding hiring for researchers and for go-to-market in both the US and Europe, and is standing up a dedicated research laboratory focused on AI and agent behaviour. Forty people today against a $50M balance sheet and 20+ live customers means the next 12 months are almost entirely a hiring problem.
Working at AIR
AIR is a AI company based in Tel Aviv, Israel. Working at a AI company at this stage means broad remit, direct access to founders, and equity that still means something if the company works out.
Tel Aviv, Israel is where most AIR positions are located.
How to actually get hired at AIR
Why applying the normal way doesn't work
At <50 people, AIR has no recruiting team. Your application lands with a founder who is also running sales, product and payroll. The obstacle isn't a queue or an ATS, it's being seen at all. Cold outreach outperforms the form here, consistently.

Founding team
Yair spent roughly a decade in Israel's Unit 8200 intelligence corps working on offensive cybersecurity, where he met his co-founder Niv Hoffman. He founded AIR in February 2026 and took it from zero to 40 people, 20+ customers and $50M raised in about six months. On the commercial side he is direct about where the company is: "We started selling to big companies and we have some big customers."
Niv is a Unit 8200 veteran with a background spanning offensive cybersecurity, enterprise infrastructure and AI security research. He co-leads the OWASP Agentic Skills Top 10 project, which is the closest thing the industry has to a shared taxonomy of how agent add-ons get abused. That work is effectively the public-standards version of what AIR Filter enforces commercially.
What to show them
Pick a popular public MCP server or Skill with real install numbers. Reverse it. Write up exactly what it can reach that its description does not disclose — network egress, credential scope, filesystem access, transitive fetches at runtime. Then write the detection: the specific static or behavioural signal that would have flagged it inline before the payload entered an agent's context. Map your finding to the relevant OWASP Agentic Skills Top 10 category, since Niv co-leads that project and will read it in that frame.
A cold email that works at AIR
What AIR screens for
Sequoia led at $10M and Greenoaks came in at $40M within weeks, which tells you the round was priced on speed of category capture, not on metrics. The angel list is the other tell: Wiz, Eon, Clay and Cognition founders plus Anne Neuberger, and a CSO hired out of the Disney and Costco CISO seats. That combination is a company being built to sell to enterprise security buyers from day one. For a candidate, the window is the gap between now and the marketplace launch: joining while the vetting corpus is still being built means your judgment about what counts as risky becomes the product's default. That authority disappears once the allowlist calcifies.

Avoid
Don't make these mistakes
Do not open with how excited you are about agent security as a category. Yair and Niv spent a decade in Unit 8200 doing offensive work and have been reading agent add-on code all year; category enthusiasm from the outside is the least valuable thing you can offer them. Also skip the generic prompt-injection demo — they have seen thousands. What lands is a specific supply-chain finding: a real MCP server or Skill you pulled apart, what it exfiltrated or executed, and how you would have caught it inline. Treating this as a model-safety problem rather than a dependency-provenance problem will read as not having understood the product.
Mistakes that kill AIR applications
A recycled CV gets rejected fast at AIR (<50 people). They notice.
Don't open with what you want. Open with what AIR is dealing with right now — Every serious enterprise agent deployment in 2026 runs on an add-on layer that resembles the early npm ecosystem: open publishing, no provenance, transitive dependencies, and installation counts in the millions, and what you'd do about it.
Most AI applications get ghosted. A day-five follow-up can double your response rate.
