Today we're launching Index: a platform for content owners to understand how AI agents use their work, and earn revenue when they do.

Our first partners include @TheAtlantic, @FortuneMagazine, @PRNewswire, @PitchBook, @ZoomInfo, @Tracxn, @RocketReachCo, @enigma_data, @fiscal_ai, plus creators @alexeheath, @mariogabriele @azeem, @every, and @packyM.

[Arpan Shah @arpans]

Today @sparkcapital is co-leading the $100m seed in @radixark with @Accel and partnering alongside many of our other friends across the venture community:

A bet on @ying11231 , @BanghuaZ, and the @lmsysorg , @sgl_project community, and on the idea that open infrastructure is how the next era of AI gets built.

[Clay Fisher @claymfisher]

Congrats to @paraga and @travers00 and the entire team at @p0 as their prescience comes alive at astonishing speed.

[Natalie Vais @natalievais]

Thrilled to lead @mastra's Series A. Mastra has quickly become the default framework for building TypeScript agents. @calcsam @abhiaiyer @smthomas3 know how to build great OSS, earn developer trust, and ship fast. We're excited to support them on this next phase 🙂🚀

[Sam Bhagwat @calcsam]

We’re excited to announce today that @mastra has raised a $22M Series A led by Spark Capital.

This brings our total capital raised to $35M:

Last month proved that your security is only as strong as your weakest dependency.

The attacks against Trivy, LiteLLM and axios showed that you can’t patch and scan your way out of a broken trust model.

We took an ad out in the @BostonGlobe to share our POV.

[Nabeel Hyatt @nabeel]

So happy to have @sparkcapital co-leading the Series A in @conductor_build !

Can you believe 24 months ago coding w/AI meant github auto-complete? The way we work with software is an avalanche of change, from Co-pilot to Claude Code, and we are mid-revolution.

This is not a think piece -- just use @conductor_build -- it's ridiculously good software, you'll see.

There are preciously few times where you use a product, and every update feels like you are on the ride with people who are "sense-making" the edge of what is possible into things that are just head-smackingly simple and obvious -- once someone does them.

That's @charlieholtz, jackson, and the team. They have that touch of creative technologists, this rare ability to internalize what we are all doing in vibe coding in ways we haven't even articulated yet, and giving it surface area. So excited to be on the ride with them!

@latent_health is one of the biggest and most strategic opportunities in healthcare, sitting in between providers, payors, patients, and pharma and $200B of pharma spend. @sparkcapital is delighted to support Rish and Sri and this consequential company and to work with @saranormous and Mike Dixon.

[Yasmin Razavi @YasminRazavi]

The @MatXComputing team is ambitiously building the compute infrastructure for our AGI future. It’s been a pleasure working with @reinerpope, @MikeGunter_ , and the team this past year. Incredible milestone and the best is still ahead.

Congrats to https://t.co/xV33ufmNXJ on the acquisition by Apple, the second largest in their history.

In 2022, Aviad cold emailed out of the blue. He barely even told me what he was up to. But from the very first call it was obvious I had met a force of nature, and a kindred spirit.

These folks have really made magic, oh how I wish this wasn't in stealth so you all could see. But with Aviad & team inside of Apple, the magic is sure to hit us all soon enough.

@sparkcapital are so happy to have had the chance to partner with them. Congrats to the Q team!

b10’s inference infrastructure powers the most sophisticated app companies serving specialized models at scale. there are dozens of these companies today and there will be thousands in the future. incredible momentum + world-class talent density.

and, it’s still so early…

$400M Series F | $9B valuation 🚀 Here’s why this is fuel for what’s next here at @cyera_io 👇

AI’s first wave showed what’s possible with public data. The next wave is about what AI can do with enterprise data.

As agentic AI scales, systems are already acting at a pace humans never could - creating exponentially more data, decisions, and therefore risk. The challenge isn’t building AI, it’s making it secure enough to run everywhere.

Legacy security wasn’t built for this. Traditional controls are blind to how AI uses data, forcing enterprises to choose between slowing innovation or accepting risk.

✨ Cyera is built to change that, securing AI holistically across data, access, and models, so organizations can move fast without losing control.

This funding supports the next chapter of our mission: extending our core strength in securing data to unlock enterprise AI adoption at scale. But the real engine behind it is our team - the builders, operators, marketers, and partners working at Cyera speed every day to create what doesn’t yet exist!

[Yasmin Razavi @YasminRazavi]

Of all the directions we could point AI, accelerating scientific discovery and collapsing years of research into days feels among the most profound.

Excited to be backing @SGRodriques , @andrewwhite01, and the entire @EdisonSci team. For those who are mission-aligned, joining Edison could be a once-in-a-lifetime opportunity; and the good news is they’re hiring!

The web was designed for humans. It now has a new customer: AIs. And when there’s a new customer, everything changes. Search for humans is about ranking URLs for humans to click. Search for AI is about maximizing the ability of the agent to do its best work. In other words, it's about giving an AI “perfect” context, which is our most powerful lever to change what a base model does. To do this, the web and search needs to be re-designed: from crawling, indexing, ranking algorithms — to even content monetization schemes. This is an enormous project — one that takes audacity, brilliance to play at the frontier, and an indomitable spirit. We’ve found these qualities in @paraga and the entire @p0 team and we're thrilled @sparkcapital to partner with them as they build the web for the age of AI.
