Something unique about Method is that we have stuck to our guns on our original business and technical strategy, almost to a fault. Pivoting is not for us.

It was fun prepping for this interview reading our seed investment deck looking at how little has changed. Thank you @NSheinbaum for having me on.

Maybe Mythos hacked every DoW system on earth in ten minutes.

Maybe that was a misquote through layers of the DC swamp.

Either way, one thing's for sure:

America is now in a race against our adversaries to operationalize frontier models for cyber offense.

We started Method to help us win.

We're proud to deploy with cyber operators protecting our institutions and deterring our adversaries.

If that sounds like your mission too - come join us. 🇺🇸

Palantir calling out what we're hearing from our customers at Method: compliance theater doesn't stand a chance against adversaries armed with LLMs.

Their security team has set the bar for years. Awesome to see @ssankar and the team raise it with a new standard for readiness.

[Palantir @PalantirTech]

Introducing MA-S2: Mission Assurance Security Standard for Software.

AI is accelerating vulnerability discovery. Adversaries are moving faster than any human team can respond.

Institutions need autonomous remediation, attack path modeling, and domain awareness.

The bar has changed.

MA-S2 is our proposed standard for software security — one we're actively working towards, and publishing as our responsibility to every enterprise that wishes to secure its own digital footprint and ecosystem.

@wolfejosh brother

just wait until you see what we're building right here in america at @method_security :)

@EugenAlpeza @sequoia @8vc @A_StarVC congrats!

We've been lucky to work with Michelle since day one at Method.

Hard to think of a better first investor for founders building in defense.

Excited to see Pax come together!

[Michelle Volz 🇺🇸🚀 @MichelleVolz]

Excited to officially announce the launch of Pax Fund I, a $50M early stage vehicle dedicated to founders transforming the foundational categories of society. 🇺🇸🚀

Wrote a bit about my journey and the thinking behind Pax below:

@tldrmorgan Congrats!

[Sean Hacker @seanhacker]

U.S. Government cyber operators deserve both bleeding edge frontier models and world class software in order to supercharge their capabilities. We're delivering trustworthy autonomy to the mission environments where operators need it most.

[Daniel Kelly @dan__kelly]

Excited to announce Method's strategic partnership with OpenAI.

We believe autonomy will define the next era of national cyber defense. This partnership is building the infrastructure to deliver trusted AI capabilities to American cyber operators. 🇺🇸

[Method Security @method_security]

Method and OpenAI have formed a strategic partnership to deploy AI capabilities for U.S. National Security cyber missions.

U.S. cyber operators defend the largest and most complex attack surfaces on earth. As adversaries weaponize AI at scale, national cyber readiness now depends on safely deploying autonomy to re-secure our critical institutions.Method and OpenAI are developing a joint solution for the Defense Department and Intelligence Community.

By embedding OpenAI’s frontier models into Method’s cyber operations infrastructure, we’re delivering scalable, secure autonomy that powers resilience and gives defenders a force-multiplying advantage.

Mark is the rare kind of investor who makes your mission his own.

Lucky to have him behind Method.

[Mark Crane @CraneMcrane]

Today we announced our investment in @method_security, partnering with @___sjones, @dan__kelly, Sean and the incredible team to build the autonomous future for cybersecurity. A little story about how this happened… (1/5)

@signulll criminals tend to stay on the run

[TBPN @tbpn]

“I guarantee you the most sophisticated [nation-state] actors are not using vanilla Claude code to run their operations.

That’s ludicrous.

Our adversaries have better models at home that they make themselves.” @___sjones, CEO Method Security

[Daniel Kelly @dan__kelly]

@davidu @willbitsky @CraneMcrane @markscianna @fkerrest @philvenables @eaescob @internet_meme plus @AliBHamed @MichaelOvitz @MichelleVolz @Jillwillnyc @barrald @JKeidan @davealevine @scottbelsky and @eisenberg !

[Daniel Kelly @dan__kelly]

Excited to share what we've been working on at Method and announce our $26M in funding from Andreessen Horowitz, General Catalyst, Blackstone, and others.

I met @___sjones and Sean ten years ago at @PalantirTech.

We always talked about starting a company together, and when we saw how AI would shift the balance of power in security, we had no choice not to.

We started Method to build the tools that American cyber defenders need to achieve real resilience in the face of autonomous threats.

Two years in, we've put together an incredible team of engineers and operators to go after this mission and are deployed with some of the top security teams in the country.

We're grateful to be backed by investors like who believe that American cyber resilience is a challenge worth solving.

We are just getting started.

[Method Security @method_security]

Method is building autonomous cyber systems for the U.S. Government and critical enterprises.

America is facing perpetual cyber conflict. With AI accelerating the speed and scale of attacks, U.S. cyber operators need new capabilities to stay ahead.

Method is delivering those capabilities.

We are building the command-and-control layer for autonomous cyber operations. Our products fuse offensive and defensive capabilities into a full-spectrum platform, enabling security teams to achieve true visibility, challenge their estates, and outpace their adversaries.

Today, Method is deployed across the Defense Department, U.S. Federal Government, and Fortune 500.

We've raised $26M from @a16z, @generalcatalyst, @blackstone and others. This funding accelerates our mission to equip the security teams defending what matters most.

[Daniel Kelly @dan__kelly]

Grateful for support from investors like @davidu @willbitsky @CraneMcrane @markscianna @fkerrest @philvenables @eaescob and @internet_meme

[a16z @a16z]

Today, we’re excited to share that we’re backing @method_security as they come out of stealth.

With adversaries using AI to scale threats to new magnitudes, the American government and other critical US institutions are not equipped for today’s cyber conflicts.

Method integrates diverse data sources into a digital twin, providing security teams with complete visibility and allowing for sophisticated simulations of autonomous attacks.

[Mark Scianna @markscianna]

@method_security out of stealth today and tackling one of the hardest problems in national security.

Cyber offense is scaling to infinity as adversaries weaponize AI into machine-speed attacks. Method Security provides enterprises autonomous systems to counter these persistent threats, built by a founding team from Palantir, Shield AI, NSA, USAF, CrowdStrike, Microsoft, and AWS.

Proud to back @dan__kelly, @___sjones, Sean and team!

[will bitsky @willbitsky]

2013 me was lucky to meet @___sjones as a student at cornell

2025 me was lucky to join the @a16z team that backed his company @method_security

congrats guys, huge day
