Excited to share @RoadrunnerAI has raised $27M in funding across a $5.2M seed led by @mamoonha at @kleinerperkins and a $22M Series A led by @traestephens at @foundersfund.

We started the company in August - and the business has basically been happening to us since we incorporated.

Building AI agents for the enterprise to run one of their most important production systems is not for the faint of heart. But the pain around CPQ is very real, and we’ve been overwhelmed by demand from companies looking for a better way forward.

Our ability to serve more customers in pursuit of building a generational company is almost entirely bottlenecked by our ability to hire the top 1% of talent. If you're interested in joining us, reach out!

Thanks to @agarfinks and @FortuneMagazine for covering part of the story! Link to article in comments!

[Kleiner Perkins @kleinerperkins]

Roadrunner started inside our San Francisco office, our first incubation since @Glean.

We spent a lot of time looking at where enterprise software is breaking down, and one category kept coming up: CPQ. It sits at the center of every enterprise deal, yet the category hasn’t kept pace with how modern deals actually get done. @RoadrunnerAI is rebuilding it from scratch.

Excited to work with @Joubinmir, @ajnatarajan, @eshao18, and the incredible team they’re building.

To make history, you have to honor it.

A look back at the people, partnerships, and defining moments that shaped Kleiner Perkins, and still guide how we back founders today.

[Kleiner Perkins @kleinerperkins]

For more than 50 years, Kleiner Perkins has partnered with founders at moments of inflection. AI is reshaping every industry from the ground up, faster than anything we've seen before. This is the moment to build.

Today, we're proud to announce KP22, our twenty-second venture fund: $1 billion to back early-stage companies, alongside $2.5 billion in growth funds to back high-inflection, category-defining businesses.

A moment like this is where the most enduring companies take root. Deep founder relationships and hands-on support matter more than ever, and we believe in lean investment and portfolio operating teams that work on founder time to deliver exactly that.

We're so grateful to the founders and LPs who have trusted us over the years. We couldn't be more excited to partner with the next generation of history-making companies.

Across basically all scaling early-stage startups I know (even now in the age of AI codegen) - there is always an unsung hero infra/security engineer who is a key part of fixing every severe outage. Early days @scale_AI it was Calvin Huang. Who are other good examples of this?

[Joubin Mirzadegan @Joubinmir]

Excited to finally share more about KP’s first incubation since Glean: @RoadrunnerAI.

Building this company with Ajay Natarajan, Eugene Shao, and our incredible team has brought me the most energy I’ve ever felt in my career. Grateful to @kleinerperkins and @mamoonha for backing this - and for letting us build upstairs in the SF office for the past several months 😬.

Huge thank you to our design partners who took an early bet on us to codevelop a solution that finally fixes CPQ.

We marked the moment by flipping the script on the @KPGrit podcast. Mamoon interviewed me about my story and how many unlikely turns ended up pointing toward Roadrunner.

If you’re interested, reach out. I’ve never seen this level of pent-up customer demand, and I’ve never seen an engineering team ship with this level of velocity and craft.

Working with the next household name in this list (currently ~Series B stage), where a staggering ~1/3 of the team is former founders. They are hiring! Message me for details.

We're heading west to San Francisco! 🌉🇺🇸

When @thejamescad and I met in the hallways of @southpkcommons in New York City, we knew that whatever we decided to dedicate the next 10 years of our life would be built in NYC.

In the past 14 months, we've grown @tryprofound from just two people with laptops into a thriving business with 82 teammates, serving 1,000+ enterprise customers across three offices.

Now we're opening a new office in San Francisco dedicated to Tech & GTM.

I met @_dan_lee_ at @scale_AI years ago. Dan always impressed me with his ability to focus on the customer. That focus led him & the @JoinNooks team to bring AI to sales teams in a human-centric way. We’ve met countless customers who couldn’t go back to life without Nooks — the usage and results speak for themselves, and we’re excited @kleinerperkins to be part of the journey.
