How it works

Not a collection of isolated groups. One operating model.

Every community belongs to a clear technical domain and shares common standards, operations, speakers, sponsors, content and discovery. You get the feel of a local group, with a model that works for speakers and partners.

1
Communities
Practitioner-led groups for people working in a specific area, from AI and cloud to platform engineering, finance technology and startups.
2
Global chapters
Online communities that connect practitioners across regions and bring related groups together under one programme.
3
Conferences & forums
Flagship summits, senior forums and specialist conferences for deeper content and more focused conversations.
4
Partners & sponsors
Ecosystem-level partnerships to support communities, contribute speakers, host events and build long-term relationships.

Built around practitioner audiences

Designed for the people actually building, operating and leading technology, so every room has a clear purpose.

Fewer, better, more focused events

Less overlap across the portfolio, stronger leadership forums and more impactful conferences. Better rooms, not just more of them.

Shared standards and operations

One playbook for speakers, sponsors, venues and content, so quality holds from a local meetup to a flagship summit.

2026/27 Conference Programme

Thirteen conferences. Calls for speakers are open.

Every conference sits inside a wider community, connecting attendees, speakers and sponsors with a focused practitioner audience. Every upcoming conference is taking talk submissions.

Ecosystem partnership

Beyond logo placement.

Sponsorship here is about access to communities, not visibility at a single event. Partners join curated dinners with senior practitioners, get introductions through our speaker pipeline, help shape the year's content themes at roundtables, and get reporting on engagement across the whole portfolio.

We work with a deliberately small number of partners per ecosystem, so each relationship has room to do real work. Most partners stay with us across several years and several ecosystems. That continuity is the point.

What this is built to become

Practitioner infrastructure, at the scale the industry now needs.

Eighteen communities is the start, not the destination. Over the next three years the portfolio will grow into more domains, more regions and more conference formats, always under the same model: practitioner-led, theme-aligned, curated rather than scaled, reinvested rather than extracted.

The next decade of technology will run on the trust networks communities create. The question is whether those networks are built as infrastructure, or left to chance.

Find your place in the portfolio.

Whether you're looking for your community, have lessons worth sharing, or want to support technical ecosystems responsibly.
