We were just named to The Information's 50 Most Promising Startups.
They call it "The 50 startups most likely to become tomorrow’s giants."
Based on their track record, they're usually right.
This same list picked Cursor at a $400 million valuation, Polymarket at $200 million, and Grafana at $325M.
Later today, at 12PM PT, I'll be speaking live for a conversation with The Information team and a few other members on the list. I'll drop the link below.
Congrats to everyone else who made it, and thanks to @aaronpholmes and @TheInformation for the recognition.
Most of all, thanks to the team. I'm proud of the work they've done to get us here, and land us on lists like this.
On that note, this is your last chance to join us before we go parabolic. We're hiring for a ton of roles to scale enterprise AI adoption to every company on the planet.

The best time to join a rocketship is before everyone knows about it.
I’m excited to launch The Next 50: the 50 hottest early-stage startups to keep an eye on (and try to join).
Using @harmonic_ai’s data, the juiciest startup dataset out there, we looked at every early-stage startup and ranked them on headcount growth, recent funding, and investor interest.
We then picked the top 50.
Here's the full list: lennysjobs.com/next50
We’ll update it quarterly, and I’d love your feedback on what other factors we should consider.
P.S. This is in addition to the Lenny 100, the top 100 well-known companies with the highest talent density, tackling the most ambitious problems: lennysjobs.com/lenny100

🚨 IF YOU'RE BUILDING AN AI CLIENT, YOU SHOULDN'T NEED TO CARE ABOUT SECURITY 🚨
Speak a standard instead: emit events in one shape, obey one checkpoint, and any security tool plugs in.
We (@runlayer) proposed it at [un]prompted II. Open at AAIF 👇
github.com/aaif/wg-security-…
🚨 Last week some very famous AI agents did time behind bars. 🚨
We locked them in a truck when we rolled up to @aiDotEngineer NYC. Rogue agents are a lot less scary with identity, access control, and audit trails built in.
Don't worry, they're out on good behavior. 👀
Find us at the @AgenticAIFdn AGNTCon + MCPCon today to see how Runlayer keeps every agent in line so your team can focus on shipping.
Your employees generate millions of AI events every day. Legacy security tools see and understand almost none of it.
Runlayer Runtime Security delivers AI-ready defense in depth, so you can keep up with AI without giving up on securing it.

"If a peer comes to ask me how to deal with the agentic risk that we're all seeing the first thing I'd tell him or her is to get Runlayer." - Jonathan Jaffe, CISO at Lemonade
We're proud to partner with @Lemonade_Inc to govern their agentic workloads.
Over the past 90 days, Runlayer has managed 300K MCP tool calls across Lemonade's 1700+ person workforce while executing 25M+ security checks.
"Runlayer has allowed Security to enable the business rather than be a source of friction."

Today, we're launching the ability to say yes to Muse at work.
People are giving Muse access to their company's most sensitive data & systems. Yet companies have no way to control this access. Many are blocking it. Others have had Muse go rogue, leaking company data, sending unauthorized emails, and more.
Runlayer provides hundreds of secured connectors for Muse, governed by deterministic policies & runtime security models that you can control. Runlayer also detects when Muse is being used within company systems without governance, and alerts you.
Teams get access to the most powerful personal agent. Companies maintain security and control. Win win.

my AI Engineer talk is finally online
a bit outdated already but one thing will be probably always true - failed agent runs are your richest signal
youtu.be/u-o0sW9nwmk?is=BcYS…
Legacy security tools see a malicious skill when it runs.
Runlayer scans it the moment it lands on the endpoint.
Sessions & Shadow AI: proactive detection, full session telemetry, enterprise-scale deployment.

mcp is dead, long live mcp? collabed with opus to put together this 102 explainer. there's plenty of content on "what is mcp" not enough on MCP & context window
i covered:
- context bloat, and why it turned out to be a client problem
- servers hiding all their tools behind search & execute
- the "just use CLIs" take, shipped to a 5,000-person company
- why boring standards win
0:00 - MCP is dead (again)
0:29 - The original sin: context bloat
0:53 - Plot twist: it was a client problem
1:23 - The meta-tool detour
1:56 - This year's hype: just use CLIs
2:37 - What MCP actually bought you
3:28 - Two-way street
3:50 - How standards win
Everyone is building an agent builder. Then they try to layer security on top. We did it the other way around.
Runlayer Agents are powerful, secure by design, and easy to use. Every agent ships with identity, access controls, and deterministic policies built in. You don't have to choose between usability and security.
