Who should own the agentic AI stack your teams build on?
How goose led to the AAIF
Manik Surtani, CTO and co-founder of the Agentic AI Foundation, on goose, the coding harness Block open sourced, and why people should own their AI destinies.

Manik Surtani is CTO and co-founder of the Agentic AI Foundation (AAIF), the Linux Foundation home of MCP, goose, AGENTS.md and A2A. Before that he was head of open source at Block, where goose began.
Rather just listen?
In brief
- goose began at Block as an internal coding harness for large language models, and predates Claude Code.
- Block open sourced it to see what the community would do with it; people started using it, forking it and improving it.
- That traction is where the Agentic AI Foundation's origin story starts.
- Sovereignty: people need to own their own AI destinies, and open source has a huge role to play.

Why this conversation
Every platform team adopting agents is choosing a stack that is barely a year old: a protocol for tools, a format for instructions, a harness that writes code. Who owns those pieces decides whether you can rely on them. The Agentic AI Foundation was created to answer that question for the agentic layer, and Manik Surtani is its CTO and co-founder. I sat down with him at AGNTCon + MCPCon Europe in Amsterdam, after his keynote, and asked for the short version: why does the foundation exist?
This episode is a two-minute cut of that conversation. The rest of it, and the keynote, are written up on lucaberton.com (linked below).
The origin story starts at Block
Manik answered with the origin story. A couple of years ago he was head of open source at Block, at the very start of what he calls the large language model era. His team began experimenting with LLMs for coding and built a harness to help them write code with them: goose. It predates Claude Code, he points out, and it found a lot of attention inside the company.
So Block open sourced it, to see what the community would do with it, and it took off: people started using it, forking it, changing it and improving it. That is the moment the foundation’s story starts. In the full conversation he explains what came next. Some organisations would not contribute their changes back while one company still owned the trademarks and the roadmap; the existing foundations did not quite fit; and Anthropic was looking for a neutral home for MCP for the same reasons. So they created one.
Sovereignty
The cut ends on sovereignty, which Manik calls a big deal for him personally: “I’m a believer in people need to own their own AI destinies, and this is where open source has a huge role to play.” For a European team choosing where its agents run and whose protocols they speak, that is the practical argument for building on projects with a neutral owner.
The rest of the conversation
The cut leaves out most of what we covered, and three points are worth carrying with you. Member companies want working groups on robotics and embodied AI, and those come once the foundation has a lifecycle that can also close a group. On careers, he separates programming from software engineering: the programming can now be delegated, as assembly once was, but someone still has to understand what is being built and how the pieces fit. And the way in is open: use the projects, come to the events, start a local chapter, contribute a project or propose a working group.
What he said on stage
His keynote that morning, “Catch Them Early”, was about the foundation’s entry bar. The AAIF had inherited a bar built for a mature industry, and it was turning away projects that were technically real but too young to meet it. The fix is a Sandbox phase, a second door before Growth and Impact: a working implementation and a named, active maintainer get a project infrastructure and a neutral flag, nothing more. For a platform team, that is the signal to read before building on an agentic project: which phase it is in, and whether two unaffiliated organisations already run it in production.
Big thanks to Manik for joining me in Amsterdam.

0:00 Welcome to Udienza. I mean, this week has been great, yeah. Welcome to today’s podcast, sit back, lean in, and join us for an insightful conversation with Manik Surtani, CTO and co-founder of the Agentic AI Foundation, hosted by Luca Berton. Thank you very much for being on the show. I’m super excited to have you here. And I know you’re the CTO of the AAIF Foundation. Can you give a glimpse of the foundation? Yeah, absolutely. Absolutely. And thank you for having me on the show, Luca. So I think the best way for me to give you the aim of the foundation is to talk about the origin story and how it came to be. So I was working at Block at the time. It was a couple of years ago. And I’ve been at Block for a long time. And at this point, I was the head of open source for the company.
0:46 We were doing a lot of work in open source. It was a really interesting time. And it was also just the very start of the large language model era, if you will. So we started doing a lot of work with experimenting with large language models for coding. And we built a harness, a coding harness, that would help us write code using LLMs. And this predates Claude Code and a whole bunch of things like that. It’s called goose. Found a lot of attention internally. People started using it a lot. They really liked it. So we open sourced it. We said, “Let’s see what the community will do with it.” And it just took off. A lot of people started using it, forking it, making changes to it, improving it. We hope you enjoyed this, and we would also really like to let you know that we are beyond grateful for the sponsors that made this happen. So thank you, lean back in, and enjoy the rest.
1:33 There is a huge concern. Yeah, of course. Sovereignty is a big deal for me as well, personally. I’m a believer in people need to own their own AI destinies, and this is where open source has a huge role to play. We hope you’ve enjoyed this short intro into our interview with Manik Surtani, and we hope to see you at this week’s event of AGNTCon in Prague. See you there! Udienza!
