Sponsor high-signal CTO gatherings.
Partner with CTO Circle to show up around curated in-person events for 50–80 CTOs and engineering leaders in cities like Barcelona, Madrid, and San Francisco.
Support the kind of event people stay for.
Open-air intros, drinks, and a room that still feels intentionally small.
Who actually attends these events.
Sponsors are not buying generic reach. They are stepping into a curated room of senior technical operators, with clear filters on who gets in, what kind of companies they come from, and the kind of software work those teams are actually doing.
30-40%
Applications selectedProfile fit comes first
We only admit CTOs and senior engineering leaders. Applications are screened to keep the room genuinely peer-level rather than broadly open.
- CTOs, VP Engineering, Heads of Engineering, and equivalent senior technical leaders
- 30-40% of applications are typically selected
- The goal is operator density, not maximum headcount
42%
Scaleup mixA room weighted toward operating companies
The attendee base usually skews toward scaleups, with a smaller share of enterprise and early-stage product companies in the mix.
- Typical mix: 8% enterprise
- Typical mix: 42% scaleups
- Typical mix: 21% startups with 5+ employees and 29% startups below 5 employees
84%
SaaS companiesSoftware is core to the business
What most companies in the room share is an in-house software team. The majority are SaaS businesses, while the remainder still operate with real internal engineering teams.
- Every company represented has an internal software team
- 84% are SaaS companies
- The remaining 16% span consulting and other software-driven businesses
More intentional 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.
Curated audience
CTOs and senior engineering leaders join to trade operator lessons with peers who carry similar responsibility.
- Technical leaders from product-minded companies
- Peer-level conversations with practical signal
- Designed for senior operators, not broad startup traffic
Year-round community
CTO Circle is not a one-night mailing list. Sponsors show up around a community that keeps talking after the event.
- Private Slack community with ongoing discussion
- Regular one-on-ones and introductions between members
- Useful perks that keep the ecosystem active between gatherings
Trusted environment
The community is explicit about respecting the room: no spam, no aggressive selling, and no low-signal activations.
- Community-first rules shape event behavior
- Commercial activity must fit the context
- Sponsors are expected to add value, not noise
Small 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.

Year-round
Community follow-throughSlack, intros, one-on-ones, and perks keep the network active between nights.
Short-form sessions designed to spark better conversations, not stage theater.
Dense rooms with the right peer mix and enough space to actually interact.
Food, intros, and post-talk follow-through are part of the format.
Already convening the right people.
These gatherings are not theoretical. Sponsors are stepping into a format that already exists, already attracts strong operators, and stays intentionally small enough to feel high signal.

“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.”

A year-round community, not just event nights.
CTO Circle members already use partner perks and operator-focused offers inside the community. That keeps the ecosystem useful between events and makes sponsorship feel connected to something ongoing.

Who attends CTO Circle events?
CTO Circle events are designed for CTOs and senior engineering leaders, with applications reviewed to keep the room high signal and peer relevant.
What kind of sponsors are a fit?
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.
Can we sponsor multiple cities?
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.
Can we propose a custom activation?
Yes, as long as the idea improves the experience for attendees and stays aligned with the community-first tone of the event.
Are pitches or recruiting booths allowed?
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.
For companies that want to support real operator conversations.
If your brand fits a room built on practical leadership, trusted intros, and in-person depth, let's talk about the right event or city.
