Call for Papers: The Guide to Conference Submissions That Get Accepted

A call for papers is the public invitation a conference uses to collect talk proposals, and the proposals that get accepted fit the programme and arrive in sufficient numbers. What you submit is an abstract, a short description of the session you plan to give, along with a title and a short biography, and the finished talk is only needed after acceptance. A programme committee compares all proposals in a topic area against each other and awards only a few slots. This guide works through the questions about calls for papers and submissions one by one and points you to the articles that go deeper on each of them.

What is a call for papers, and how does it work?

A call for papers, or CfP for short, is a comparative selection process with a fixed deadline in which a conference states publicly which topics and formats it is looking for in its next edition. The name comes from academia, where conferences really do collect full research papers. In the business world the same process is often called a call for speakers or a call for proposals, and what you submit is a proposal for a session, meaning a single programme item such as a talk, a workshop or a seat on a panel. What a CfP asks for in detail and where the term comes from is explained in What is a call for papers?.

The process has four phases that look much the same at almost every conference. First the organiser opens the submission window, which stays open for a few weeks. Once it closes, a programme committee, the group that puts the programme together, reviews all proposals and ranks them. Acceptances and rejections then go out, and only in the last phase is the actual talk built, with several months usually left between acceptance and the stage. How long each step takes is set out in the timeline from call for papers to stage.

Today most submissions go through platforms. A large share of technology conferences use specialised submission systems where you create a profile and store your sessions, so that every further submission to a conference on the same platform needs only a few extra details. Other organisers collect proposals through their own form or by email to a named address. Which systems are common and how they differ is covered in the article on submission platforms for speakers.

What goes into a conference submission?

A submission contains the title and the abstract, usually a session description of 150 to 400 words, along with a short biography. Depending on the conference you also state the track, meaning the thematic strand of the programme, the level of the talk as well as its format and length. Each of these fields answers a separate question for the committee, and one weak field pulls the whole submission down in the comparison.

The title decides whether a reviewer reads the abstract with any attention at all. It later becomes the line that promotes the session in the programme, which is why the committee reads it through the eyes of an attendee choosing between parallel rooms. Why it carries so much weight is explained in The talk title decides whether your abstract gets read.

The abstract shows whether the talk names a problem this audience recognises from its own work and whether there is a coherent line of argument behind it that leads to a result within the allotted time. A committee reads it as a promise to the attendees. What an abstract has to achieve and how it differs from a sales description is explained in What is an abstract for a conference?.

The biography answers the question of risk. An organiser who puts an unknown person on the programme has to answer to the audience and to sponsors if the talk falls flat, so the bio is read for evidence that the person knows the subject from their own practice. Demonstrable expertise convinces even without a long list of past talks, and how a bio conveys it is covered in What a speaker bio has to achieve.

Language is a special case. Many conferences, in Germany as well, run their call in English and expect English submissions. A literal translation of a German abstract often reads stiffly, because conference English works with shorter sentences and more direct promises. What matters here is covered in Abstracts in English.

How does a programme committee decide?

A programme committee decides on fit with the audience, on how a proposal stands out from the other submissions in the same track and on the risk it takes with the person. It never reads a submission on its own. Every proposal is set against all the others received for the same track, and within that comparison the committee awards a limited number of slots. A solid submission therefore often loses to another that offers the same topic with a sharper problem or more concrete experience. The logic of the programme adds to this: a committee that already has three sessions on a topic will not take a fourth, even a strong one.

The first pass is a pre-sort that takes only seconds per submission. Proposals drop out here if they fit no track, ignore the required fields or sound like a product pitch. Industry conferences are strict about sessions passing on knowledge, because their audience pays for content and reacts badly to sales intent. Only what survives this pass is read in depth and set against the competition in the track. Which signals a committee reads and where most submissions fail is covered in What a programme committee looks for in an abstract.

The type of review plays a part too. In a blind review the committee sees no names and judges the content alone, which helps experts with no speaking history. In an open review the bio and past talks feed into the assessment. This form is more common at commercial conferences, because the organiser sells tickets and sponsorship packages there and wants to protect the programme accordingly.

What is the acceptance rate for calls for papers?

At the volume of submissions a predictable pipeline needs, 5 per cent of conferences at most accept as a market norm, and we achieve up to 19 per cent per conference for our clients. There is no public statistic on acceptance rates in the business world so far. The figures that circulate online mostly come from peer review at academic journals and say little about industry conferences.

The most reliable basis is therefore our own submissions for clients. Of 2,189 abstracts submitted, 1,374 have been decided, and 94 of those were accepted, which is around 7 per cent per abstract. Because several abstracts often go to the same conference, the conference level is more telling: of 433 conferences that have decided, 83 accepted, around 19 per cent.

The rate gives you a calculation you can use to plan any submission pipeline. With n submissions at an acceptance rate p, the chance of at least one acceptance is 1 − (1 − p)^n. If you submit to twenty conferences at the market norm of 5 per cent, your chance of at least one acceptance is around 64 per cent, and a good third of such rounds end with no acceptance at all. At 19 per cent per conference the same chance rises to over 98 per cent.

Where the range between 5 and 19 per cent comes from is explained in What is the acceptance rate for calls for papers?. How many submissions stand behind a given number of talks per year is worked through in How many submissions does one acceptance take?.

When are the deadlines, and how early do you need to submit?

In our analysis of 2,415 conferences that publicly invite talk proposals for 2026, the median gap between submission deadline and conference start is 50 days. The average is higher at 65 days because some conferences close their calls very early. For planning, this means a conference in June has often closed its call in April, and if you only hear about it when the programme is published, you wait for the next edition. What these lead times mean in detail is covered in How far ahead do you submit?.

Conferences are spread unevenly across the year. In the same analysis, 417 conferences take place in the first quarter, 717 in the second, 457 in the third and 824 in the fourth. October is the busiest month with 346 conferences and July the quietest with 92. Calls for autumn conferences therefore run mainly in summer, and calls for spring in the winter months before, so anyone who spends the summer break on holiday misses a large share of the deadlines for the busiest conference period of the year.

This gives the deadline calendar its most important property, which is that it never stops. At any point in the year calls are closing somewhere that would suit your topic, and a conference list that was right in spring is out of date by autumn. When most deadlines fall is shown in Call for papers deadlines and When is conference season in Germany?.

Which conferences have a call for papers?

Open calls for papers are found above all at technology and software conferences, along with many industry and specialist conferences that open part of their programme to public submissions and fill the rest by invitation. Our database holds around 22,700 conferences, and on the reference date of this guide around 1,500 calls for papers were open. The market behind them is large: according to the Meeting- & EventBarometer, 2.02 million in-person events with 395.1 million participants took place in Germany in 2025, from seminars to congresses. How to find the stages where your clients sit is covered in Industry conferences in Germany.

Sectors differ widely in how open their programmes are and whom they let on stage. The following sections cover the fields people ask about most often.

AI conferences in Germany

AI conferences in Germany for 2027 fall into three groups: research-led conferences with academic review, applied business conferences on AI in companies, and AI tracks at industry conferences ranging from manufacturing to HR. For consultants the last two groups are the productive ones, because that is where the decision makers who award projects sit. AI and data is the largest named topic area in our analysis, with 356 of 2,415 conferences or 14.7 per cent. The calls are correspondingly crowded, and an AI abstract gets through when it shows a concrete application problem from practice instead of a general outlook. Calls for conferences in the first half of 2027 run between autumn 2026 and spring 2027. Which topics are accepted there is covered in Speaking at AI conferences.

HR conferences in Germany

HR conferences in Germany range from large trade fairs with a congress programme to smaller formats on new work and people development, and many of them open speaking slots to public submissions. One example is Zukunft Personal Europe in Cologne, whose call for speakers accepts proposals for talks, panels and workshops. Submitting is free, and according to its terms the organiser pays neither fees nor travel costs. One further condition is decisive for consultants and coaches: providers who mainly sell to HR departments are excluded from the call and referred to exhibitor and sponsorship packages. How you still reach the right stages as an HR expert is covered in Speaking at HR conferences.

Developer conferences

Developer conferences have the densest CfP culture of any field, since almost every conference on programming languages, cloud or software architecture opens its programme to submissions, often with blind review by experts from the community. In our analysis 281 conferences cover cloud and DevOps and 99 cover software architecture and backend. Committees there read technically and strictly: a talk needs code, architecture decisions or measurements from real projects, and product presentations drop out in the first pass. What committees expect from tech talks is covered in Speaking at developer conferences.

Marketing conferences

At the big marketing conferences in Germany much of the programme is curated or tied to partnerships, and open calls exist mainly for individual stages and formats. DMEXCO in Cologne uses its call for speakers to invite independent voices and brand-side professionals to apply for a talk or a panel seat. According to the organiser, speakers from supplier companies only appear in the programme if their company is a registered partner. If you sell marketing services, you face the same barrier as HR providers at HR trade fairs, and a similar logic applies to the sector's festivals and search marketing conferences. Which routes lead onto these stages is covered in Speaking at marketing conferences.

Conferences in the US and in Europe

The US is the largest country for open calls: in our analysis 391 of the 2,415 conferences are in the US, followed by India with 120, while Germany ranks fifth with 88. A well-known example of an open process is SXSW in Austin, where proposals are submitted through PanelPicker and a public community vote feeds into the selection alongside the judgement of staff and external evaluators. US committees expect English submissions with a clear benefit, and the trip usually costs three days plus preparation. What works differently there is covered in Speaking at conferences in the US, and where in Europe conferences look for the most speakers is shown in Which European countries have the most conferences looking for speakers.

How do you get onto a conference without a call for papers?

You reach conferences without an open call through a direct approach to the organiser, and for many industry and association conferences this is the usual route into the programme. In manufacturing, traditional consulting and the Mittelstand in particular, organisers fill their programmes through contacts, recommendations and targeted requests. In our experience this route works best as a semi-standardised email approach with an opening tailored to each conference, ten to fifteen requests a week once the conference list is in place. How such a request is structured and when it lands well is covered in Writing to organisers directly.

A third route is the paid slot. With pay to speak the speaker pays for the speaking slot, usually as part of a sponsorship package, and that quickly costs 10,000 euros or more for a single speaking slot. Sponsored sessions are often not labelled in the programme, so for the audience they sit alongside the selected talks. Because people attend an industry conference for knowledge, a talk with visible sales intent is an expensive and weak way to win clients there. When such a slot pays off is discussed in Sponsored talks and pay to speak.

What happens after you submit?

After you submit there are usually a few weeks without news, followed by an acceptance, a rejection or no reply at all, and each of these calls for its own response. Many conferences decide only after the call has closed and notify everyone at once, and some never reply to rejected proposals. A polite follow-up once the announced date has passed is common practice and rarely read by organisers as pressure. What happens between submission and acceptance and when a follow-up is appropriate is covered in Following up after a call for papers.

Rejections almost always come without reasons, because a committee facing hundreds of submissions cannot write individual feedback. You are free to send the same abstract to other conferences afterwards, and every submission pipeline works this way. If you notice a pattern after several rejections in the same field, sharpen the title or the problem before sending the session out again. How to read a rejection and what to do next is covered in Rejected as a speaker: what now?.

After an acceptance the second half of the work begins. The technical setup, the schedule and the agreement have to be settled with the organiser, the talk is built and rehearsed, and after the talk the follow-up with your contacts decides whether the stage turns into business.

How much work goes into a submission pipeline?

In our experience a submission pipeline that delivers acceptances predictably involves at least a hundred submissions to around twenty conferences in the first month and at least fifty a month after that. This volume comes from a fixed set of prepared sessions that are adapted to each form, and on submission platforms fifteen to twenty submissions a day are realistic. Alongside these come two to three purely qualitative submissions per quarter, tailored closely to a single top-tier conference and taking hours instead of minutes. Software and technology, with their active CfP landscape, start with high volume, while manufacturing, traditional consulting and the Mittelstand start with direct approaches by email.

Then there is the work that never shows up in a submission count: finding conferences and checking their audience, tracking deadlines across the whole year, maintaining abstracts in English and German, keeping profiles current on several platforms and following up after every round. For consultants, freelancers and business owners all of this runs alongside client work, and in the weeks when projects are pressing the pipeline is the first thing to stall. Because months pass between submission and stage, a six-week pause only becomes visible half a year later as an empty calendar.

Stage Starter takes this work off your hands: we find the right calls, write the submission and submit in your name, follow up and accompany you all the way to the stage. You contribute your expertise and give your approval. Working with us starts from 990 euros net a month for the entire pipeline, while a single paid speaking slot quickly costs 10,000 euros or more. No agency can guarantee an acceptance, because the programme committee makes that decision. How submission through an agency works in detail is covered in Having your call for papers submitted for you, and what happens when the texts are written is covered in Having your abstract written.

From guide to first acceptance

Once you know the questions in this guide, you can also see how much pipeline work lies between the first abstract and the first acceptance. Whether your topic and your target clients match the conferences we submit to is something we clarify in an initial consultation.
