If you represent a company (or even an individual) interested in sponsoring C++ on Sea, welcome! This page sets out the options available. For the tl;dr - if you're just looking for the table of tiered benefits - click here.


C++ on Sea is now in its fifth year. Having weathered the pandemic in its second and third years, we're now looking forward to our third in-person edition.

In our first year we had 250 in attendance in total. A small conference, but a strong start. We had expected to grow from there, but the pandemic had other ideas.

In 2022 we had 175 in-person (with another 44 online) - which was a good comeback compared to the industry in general. We're looking forward to getting back to growth and expect something closer to 2019 figures for 2023.

Predictions are hard, especially about the future. But, fwiw, in 2019 we forecast 250 and in 2022 we forcast 150-200.

We tend to attract a little over 50% of our attendees from the UK. The vast majority of the rest are from western Europe, with a small number from further afield.

Most of our attendees are full-time C++ developers, spanning the range of experience, but with a skew towards expert level.

Types and Levels

We offer a few types of sponsorship: a traditional tiered set of packages: "Bronze", "Silver", "Gold" and, the exclusive, "Platinum".

We also have a number of more specific options that can be obtained in addition to, or even instead of, the tiered packages. These include Video Sponsorship, the speaker's dinner and coffee tokens.

And, finally, Community sponsorship - for meetups, blogs, podcasts, etc.


Tiered packages progressively add features, so Gold includes all the features of Silver and Bronze, for example.

Video Sponsorship

All talks are recorded and will eventually be made available on YouTube (note that, due to technical incidents, one or two sessions may not make it to YouTube).

The videos from 2019 (our last in-person event for which we have full data) average around 4k views - but some outliers may get many more (e.g. this video, from 2019, has over 190k views at time of writing!). At standard targeted CPM rates, and based on the 2019 view data, we expect a value to advertisers of well over £4,000 for 2023.

We have two forms of video sponsorship available:

Speakers Dinner

Gala dinner at the Leas Cliff Hall

We hold a gala dinner in the venue, with views over the sea. Attendees may purchase tickets for the dinner, but all speakers receive a free ticket - so most will be present.

This sponsorship involves covering approximately half of the cost of the speakers. In return the dinner will be branded the <your name> dinner, and you will be thanked during the evening for helping to cover the cost of the speakers' meals.

£1,750 + VAT

Coffee Sponsor

Coffee tokens from Sonar (2022)

Attendees have access to coffee urns during two breaks a day. This coffee is fine - but a good, hand served, barista coffee is hard to beat. Above the part of the venue we use is a public cafe area serving just such barista coffee!

This sponsorship would let you provide branded tokens or vouchers in the conference bag that can be redeemed in the coffee shop for up to three coffees (one a day).

This would also be highlighted in the opening address and the sponsor thanked for buying everyone coffee! We introduced this sponsorship in 2022 and it proved very popular with the attendees.

£2,000 + VAT

Travel & Team Sponsorships

If you send three of more employees from the same company, we offer to mention and thank you in the opening sessions and (if arranged in time) your logo in the "Bronze" section of the website.

Or if you are an employer of a speaker and you cover their travel and accommodation expenses we can offer the same deal.

Please be sure to contact us to make arrangements if you wish to take advantage of this option.

Upgrades to full Bronze sponsorship (or beyond) are also available.

Community Sponsorship

The community works best when it works together. Swapping logos and links is an effective way to cross-promote events, services and resources within the community. Typical examples are: blogs, meet-ups, podcasts and other conferences. No money changes hands,

Logos will be featured on the website - on the sponsors page and also further down the front page and on the schedule page but randomised on load (not all community sponsors will be on every page view).
