Most conferences fill their stages through an open call that closes six to nine months before the event — but a large share of the best events never run an open call at all. Some sell stage time as part of a sponsorship. Some only accept submissions routed through an industry association. Some are invitation-only and no form exists. Knowing which of the three you are dealing with saves more time than any submission advice, so this page covers that first, then lists what is actually open.
We track calls for speakers continuously as part of client work. Everything below was checked in August 2026 against each event's own page. Treat every date here as a starting point, not a source of truth — organisers move them without notice, and a call that was open when we checked may have closed by the time you read this. The annual rhythm further down is the durable part.

The three ways a stage actually gets filled
This is the part nobody explains, and it is why so many submissions go nowhere.
1. An open call for speakers. A public form, a published deadline, a programme committee that reads everything. This is what most people picture, and it is how developer and practitioner conferences work — Devoxx, TestCon, FOSDEM, the GitNation events. If you are unknown, this is your route.
2. Sponsorship-bundled. The stage time is a line item in the sponsorship package. There is no CFP to win because the slots were never competitive. Several large field service and industry events work this way. The submission you spent an afternoon on was never going to be read — you needed a conversation with the sales team instead.
3. Association-routed or invitation-only. The organiser accepts submissions only through endorsing bodies, or curates the lineup privately. AHR Expo is the clearest example of the first: seminar submissions go through associations like ACCA, PHCC or SMACNA rather than direct from a company. Microsoft Build, Fast Company's Innovation Festival and several trade conventions are the second — no public form exists.
Before you write anything, work out which one you are looking at. If there is no CFP page and no published deadline, it is almost certainly type 2 or 3, and the right next move is an email to the organiser asking how the programme gets built.
Open right now
Two we have removed from this list. Slush (Helsinki, 18–19 November 2026) publishes a Startup Stage pitch application rather than a general call for speakers, which is a different thing and worth knowing before you spend an afternoon on it. SaaStr's London event is worth tracking, but at the time of checking its published pages still described the 1–2 December dates as the previous year's edition, so we cannot point you at a confirmed 2026 form. Check both directly rather than trusting a list — including this one.
Confirmed for 2027, calls not open yet
Worth putting in the calendar now, because the calls for these open with little warning.
Already closed for 2026: TechCrunch Disrupt (13–15 October, Moscone West, 10,000+ attendees) closed its main speaker application in May. Its Audience Choice programme for roundtables and breakouts typically opens separately and later, which is the back door most people miss. Devoxx Belgium (5–9 October, Antwerp, 3,800+) ran its call from 1 June to 17 July.
The annual rhythm, which is the part worth learning
Deadlines change every year; the pattern does not.
Two real examples of that shape: Devoxx Belgium opened its call on 1 June and closed it on 17 July for an event in October. Figma Config closed applications in early November for an event the following June — seven months of lead time.
The practical implication: if you want to speak at a spring conference, you are writing the submission in the autumn. Companies that plan speaking quarterly are always a season late.
Where the open calls get posted
Organisers use a small number of platforms, so you can watch all of them instead of hunting events one at a time.
Sessionize is the largest — speakers build one profile and apply to every open call through it. PaperCall covers a similar range, weighted toward engineering events. CFPLand emails a digest rather than hosting calls, which makes it the easiest to monitor passively.
No single one covers everything. Watching all three takes about ten minutes a week.
How to write one that gets picked
Submit early. Most committees review as submissions arrive rather than after the deadline. Something that lands in the final forty-eight hours competes with the whole queue at once.
Answer the stated theme. Nearly every call publishes a theme or a track list. Referencing it specifically is the clearest signal you wrote this for this event. A copy-pasted abstract is the fastest rejection there is.
Propose a talk, not a topic. "The future of AI infrastructure" is a topic. "What we learned migrating 40,000 builds off a managed runner, and the two things we would not do again" is a talk. TestCon's call says it outright — they want how-to sessions and real case studies. Most committees want the same thing and do not say so.
Lead with what the audience leaves with. Three concrete takeaways beats a paragraph of positioning.
Do not pitch your product. Committees screen for it, and it is the most common reason a good speaker gets rejected. Your company gets named in the bio slide. That is the deal.
Include proof you can present. A recorded talk, a meetup, a podcast appearance. First-time speakers get accepted constantly, but organisers need evidence you will not read from your slides.
Start smaller than you think
The fastest route to a main stage is a series of smaller ones. Regional conferences, meetups and association events are constantly short of speakers, accept submissions with far less lead time, and produce the recording that makes the next application easy.
Podcasts are the same move and the easiest version of it. In our own tracking, 60 of 143 podcast responses moved toward a booking — 42%, against 24 flat declines. That is a far better hit rate than conference submissions, and a podcast appearance is legitimate proof of presentation ability when you apply to a stage.
"Of 143 podcast responses we tracked, 60 moved toward a booking and only 24 were flat declines. Podcasts are the most under-used channel in B2B because everyone assumes they're harder to land than press. They're easier."

What speaking actually produces
Being straight about this: we do not publish a hit rate for conference submissions, because we do not have a clean enough sample to quote one. What speaking reliably produces is not leads on the day.
A credential that outlives the event. "Spoke at CES" sits in a bio for years and does real work in later pitches, recruiting and analyst conversations.
Assets. The recording, the deck and the quotes get reused far more than the talk gets watched.
Reporter proximity. Trade press attends these events looking for someone to talk to who is not doing a product demo.
Something to announce. A speaking slot is a legitimate news hook in a quiet quarter.
What it does not produce is a pipeline you can attribute. Judge it as credibility, not as a channel.
The common mistakes
- Submitting to an event that has no open call. Check which of the three types it is first.
- Applying to five enormous conferences and nothing else. Ten submissions across a range of sizes beats five at the top.
- Sending the CEO by default. Practitioners get accepted more often than executives, because they can teach the audience something specific.
- Missing the second window. Many events open a later call for workshops, roundtables or lightning talks after the main programme is set. Those are far less competitive.
- Treating acceptance as the finish line. The submission takes an hour; a talk worth watching takes considerably longer.
The short version
- Three types of stage: open call, sponsorship-bundled, and association or invitation-only. Identify which before you write anything.
- Calls typically close six to nine months before the event.
- CES 2027 closes 9 September 2026 and includes a free conference pass. Web Summit and TestCon Europe are open now. Slush runs a startup pitch application rather than a speaker call, and we could not confirm a 2026 form for SaaStr's London event.
- AHR Expo 2027 closes mid-August 2026 and must be routed through an association.
- Watch Sessionize, PaperCall and CFPLand rather than hunting events one by one.
- Submit early, answer the published theme, propose a specific talk, keep the product out.
- Start with meetups and podcasts. 42% of our podcast approaches moved toward a booking.
