Why sponsor CTO Circle
A more intentional room than a generic tech event
CTO Circle events sit on top of a private technical leadership community. That changes the tone, the quality of conversations, and what good sponsorship looks like.
- Technical leaders from product-minded companies
- Peer-level conversations with practical signal
- Designed for senior operators, not broad startup traffic
- Private Slack community with ongoing discussion
- Regular one-on-ones and introductions between members
- Useful perks that keep the ecosystem active between gatherings
- Community-first rules shape event behavior
- Commercial activity must fit the context
- Sponsors are expected to add value, not noise
Inside previous events
Small-format rooms with real operator energy
The format is intentionally intimate: enough density for great introductions, enough structure for short talks, and enough time afterwards for the room to keep going naturally.
50-80
Attendees by design
Small enough to talk to the room, large enough for strong operator density.

"I joined the first event in Barcelona and gave a short talk about what it means to be a great engineer in the age of AI. I met amazing people and we went out for dinner together afterwards. I'll definitely be back for the next one."

"I attended the event in Madrid at Playtomic's offices: the atmosphere was fantastic, surrounded by top company leaders. I remember debating a particular architecture and sketching ideas on the whiteboard. Afterwards, we went out for beers. There are very few events like this."

"Even though I've been living in Barcelona for a while, I met CTOs and other tech leaders I had never connected with before. It led to truly insightful and valuable conversations."

FAQ
Straight answers for prospective sponsors
CTO Circle events are designed for CTOs and senior engineering leaders, with applications reviewed to keep the room high signal and peer relevant.
Sponsors that understand operator communities and want to add value to serious technical conversations are the best fit. The room is explicitly not for aggressive selling.
Yes. City Partner is built for a two-event run, and Series Partner is scoped custom if you want broader support across 2+ events or multiple cities.
Yes, as long as the idea improves the experience for attendees and stays aligned with the community-first tone of the event.
Not in the low-signal conference-booth sense. CTO Circle events are intentionally framed as no-sales, no-pitch gatherings, so sponsor visibility must feel useful and respectful.
