Call for Participation · 5 & 6 May 2027 · London

A seat at the table.
Not a slot on the stage.

Re:Build has two kinds of people in the room. Attendees come to learn. Participants come to give and get: hosting round tables, opening fishbowls, table-hosting The Conversation and, yes, sometimes giving a talk. We pick people, not presentations.

Applications are expected to open on 1 November 2026. Twenty to thirty minutes; links, not a CV; saves as you go.

Why "participant"

Not an attendee. Not a speaker. Something we had to name.

An attendee's job is to show up curious. A speaker's job is forty minutes and a Q&A. A participant's job is the room.

Why not "attendee"?

Because you're on the hook. You applied, we picked you, and the people around you are counting on you to host the table, open the circle, argue in good faith and make a group of strangers into a conversation. Attendees get to be flies on the wall. Participants are the wall.

Why not "speaker"?

Because a talk is one of the ways to give, not the point. Most of what a participant does happens at tables, in circles and in corridors. If what you want is a stage and a flight home, there are excellent conferences for that and we'll happily name a few.

Give and get

One long speaker dinner.

Ask anyone who has spoken at a few conferences what they remember and it's rarely the talks. It's the dinner the night before, the corridor after the Q&A, the argument that ran through lunch. Re:Build is built so that part lasts two days and includes everyone who came to take part.

What you give

  • Host a round table on a question you actually care about.
  • Open a fishbowl with a position you'll defend.
  • Table-host The Conversation: a seed talk, thirty tables, a room that can hear itself.
  • Run a talk, a workshop or a lab from your portfolio, if that's one of your offers.
  • Hold office hours. Be findable.
  • Be in the room for the sessions you're not leading.

What you get

  • Two days with around 150 people who all applied to give something.
  • The insider experience for the whole event, not just the evening before.
  • Breaks that are long on purpose.
  • The questions you hadn't thought to ask yet.
  • The people you'd otherwise only meet at an unconference on a Greek island.
  • A cohort you'll know before May. We introduce you.
The money, up front

£250 + VAT. Here's exactly what that is.

It's your share of the cost of your own seat: two days of venue, catering and swag at a London venue, at the rate we pay. Participants are not paying to speak. They're covering their own, mostly incremental, cost. Attendees and sponsors are what make the space exist.

What it isn't

  • A speaking fee. Nobody buys a slot. Selection happens first; payment follows an offer, never an application.
  • A revenue line. 150 seats at cost barely moves the budget. It's skin in the game and fewer empty chairs.
  • A surprise. It's here, on page one, before you've typed a word.

Who pays it

  • Everyone with a seat, organisers included.
  • Employers, mostly. You'll get a VAT invoice that says "conference participation" and expenses like any other event.
  • Not you, if that's the barrier. Tick the bursary box on the form. One optional line, no essay. One person decides it, outside the selection panel, and the panel never sees the answer.

Earn your seat back

Every participant gets a personal code worth 10% off an attendee ticket. When enough people use it, your £250 comes back as credit. Beyond that, credit carries to next year or goes into the bursary pot with your name on it. No cash, no downline, no selling in the hallway.

We'll publish the real line items before applications open. If sponsorship later covers participant costs, we rebate everyone equally. More on the money page, including a note you can send your manager.

How we choose

We read the whole person, and we write down why.

We're choosing a room, not a line-up, and we have more seats than a normal CFP has slots. So we don't review blind. We read everything you tell us, including who you are and who might follow you in, and every yes comes with three written reasons. Paying can't buy a seat.

  1. You apply. Who you are (links do the CV's job), up to three offers you could bring, what you want to get out of it, and whether you can be there for both days. Twenty to thirty minutes.
  2. Each reviewer names the top three things you'd bring. From a fixed list: deep experience, a strong offer, a great host, a position worth arguing, builds the format; a notable name, an interesting company, brings others; a fresh perspective, an under-represented one, crosses disciplines, outside the usual bubble. Any one of them can be the reason; a notable name counts on its own.
  3. Then a verdict and a comment. Yes, yes if there's room, or not this year. Nobody sees anyone else's verdict until they've written their own, so nobody anchors. If a reviewer knows you too well to judge, they abstain and say so.
  4. Composition. No more than three people from one employer. A real share of first-timers. Topics balanced, vendors welcome but not dominant, no product talks. The caps are written down before scoring starts.
  5. You hear by the published date, whichever way. Offers go out first, declines a week later with two honest sentences, and the waitlist is told where it stands. Fourteen days to claim a seat, then it passes on.

Provisional. Two waves so the first names are known before Early tickets, and so nobody's application sits in a pile until February.

Who's choosing

Kim Fletcher and Dan Hardiker, who ran Devoxx UK's content for years, with the steering committee: Audrey Neveu, Sven Peters and Melinda Seckington. Anyone too close to an applicant abstains and says so. The fee question and your access needs are never shown to reviewers; your representation answers reach them only if you tick the box.

The whole rubric, in public →

Not sure if that's you?

Probably it is.

  • You've been to an unconference and wished the rest of the year felt like that.
  • You've given talks and quietly thought the best bit was afterwards.
  • You've never spoken, but you're the person people end up arguing with at lunch.
  • You run a team, a community, a codebase or a grudge against a particular architecture, and you'd happily be questioned about it.

Know someone who should be in the room?

Three fields. We'll invite them to apply and tell them you thought of them. Nominating doesn't earn you anything but thanks; that's deliberate.

Nominate someone
Questions people ask first

Isn't this pay-to-speak?

No. Nobody is paying for a slot, and a talk isn't the point. It's a seat at cost price in a room we curate, with the numbers published and a bursary one tick away. If we ever charge for a stage, call us on it. More →

I spoke at Devoxx UK and never paid. Why now?

Because this is a different deal. There, your job was a talk and the ticket was the thank-you. Here, your job is the room for two days, and you're one of 150 people doing it. Think unconference, not speaker programme. More →

Can my company send five people?

Three at most, and each applies on their own merits. We cap per employer so no one organisation sets the weather. More →

What if I get a seat and then can't come?

Tell us early and it passes to the waitlist. Refund terms follow the main event's; the credit scheme doesn't pay out on a seat you didn't sit in. More →
