For major milestones we send out a newsletter. Please subscribe to our newsletter.

The conference is all in English.

We are sorry to hear that, and we understand that things do not always go to plan.

However, deadlines apply equally to everyone, so we cannot make individual exceptions or extend a deadline by email. This keeps the process fair for everyone who submitted on time.

Our team truly appreciates your interest and looks forward to your punctual submission next year. All upcoming dates are listed in the conference milestones.

Every three-day pass belongs to one of four editions. Prices step up on published dates and quotas; once an edition closes, it never reopens. All prices in EUR, incl. VAT.

Each three-day pass includes the limited shirt of its edition.

Full-day classes run 9:00–16:00 with a one-hour lunch break at 12:00; half-day classes run 9:00–12:00 or 13:00–16:00. The first masterclasses are online, more will follow.

If a masterclass has to be canceled for reasons beyond our control, such as force majeure or the trainer falling ill, we refund the full ticket price.

If a masterclass does not reach its minimum number of participants, we may cancel it. We let you know by 2 April 2027; you can then switch to another masterclass, subject to availability, or get a full refund.

Travel, accommodation and other costs are not refunded.

Teams of five or more, please contact sponsoring for the Silver package.

We accept:

• Bank transfer [actually our preferred method]
• Credit card (via Stripe)
• PayPal (for non SEPA countries)

PayPal charges high fees, which is why we offer PayPal only for non-SEPA countries. Within SEPA (the European Single Euro Payments Area), a simple bank transfer is recommended.

Unfortunately, purchase orders are only accepted from sponsors. All other tickets must be purchased directly through the ticket shop.

If tickets need to be purchased by another department, please coordinate internally to complete the transaction through the ticket shop. Purchase orders sent by email or fax will not be processed. Procurement-based purchasing is available exclusively to sponsors.

No, we do not issue quotes for tickets. Tickets are purchased directly through the ticket shop.

Quotes are only available for sponsoring packages, including the Silver package for teams of five or more.

Yes. Tickets can be purchased by invoice and paid via bank transfer through the ticket shop.

Please make sure to download the invoice immediately after purchase and ensure it is processed correctly by your bookkeeping or procurement department. All funds must be received within the stated payment term; unpaid tickets will be canceled automatically. Conference tickets will be issued once payment has been processed on our side.

Please note that while we understand there may be delays in internal procurement processes, the conference cannot accept any payment delays or provide additional paperwork, supplier onboarding, or custom processing for purchase systems. If this is not feasible, we recommend completing the purchase via credit card instead.

The conference ticket includes a light lunch buffet, coffee breaks, and light refreshments throughout the day.

While every effort is made to provide a diverse selection, some options may be limited due to local conditions. The planned options include:

• gluten-free
• lactose-free
• meat
• vegan
• vegetarian

All food will be labeled for allergens. We will conduct a representative survey before the conference to ensure an appropriate distribution of options.

Tickets can be re-assigned until two days before the conference.

All on-site tickets do include remote access, so if one does not feel well one can still join remotely.

Invoice details can be updated in self-service through the ticket shop.

When changes are made, the system automatically issues a credit note for the original invoice and generates a new corrected invoice.

The ticket category follows who pays for the ticket.

Standard: the ticket is a business expense. It is paid or reimbursed by a company or organization, or booked by a freelancer — no exceptions. This includes:

• Companies and organizational entities
• Freelancers
• Start-ups
• Public sector employees
• Private research institutes
• Corporate R&D departments

Personal:

• Self-funded: you pay out of your own private pocket, for example as a hobbyist, an enthusiast, or someone learning the language. Academic researchers and post-docs at public academic institutions also buy Self-funded.
• Student: full-time students with a valid student ID at the time of the conference, whoever pays for the ticket.

Yes. Day passes go on sale on 3 March 2027, once the schedule is published. Availability depends on overall ticket sales and venue capacity. Day passes do not include a shirt.

Tickets for the Social Event can be purchased as an add-on to any on-site conference ticket from day one in our ticket shop. Please note that space is limited. Day pass holders can only add the Social Event to a day pass for the day it takes place.

The Student ticket is available for anyone who holds a valid student ID at the time of the conference. The student ID must be presented upon first entry to the venue.

Please note that if student status ends before the conference takes place, the Student ticket is not applicable.

Eligibility is limited to full-time students. We cannot accept applications from part-time students who are completing their degree alongside full-time work. Part-time jobs to support your studies do not affect eligibility.

All ticket prices include 19% VAT.

The EU VAT reverse charge does not apply, as conferences are taxed in the host country. Companies may apply for a VAT refund through the local tax authorities.

Yes. Each three-day pass includes the shirt of its edition: four editions, four designs.

Every edition is limited: the shirts are custom made in the exact number sold — no reprints, no sales, no shirts at the door. Sizes are final on 31 March 2027; no changes or additions after that. Day passes do not include a shirt. See the size tables before you order.

Every three-day pass belongs to one of four ticket editions, and each edition has its own T-shirt design. Your edition is the one on sale on the day you order, so the earlier you buy, the earlier your edition.

Sizes are final on 31 March 2027, no changes or additions after that. The shirts are custom made in the exact number sold: there are no reprints and no shirts at the door. Day passes never include a shirt.

Once an edition closes, it never reopens, so its shirt cannot be ordered later either.

Yes, until 31 March 2027. You can adapt your personal information (name, contact details, etc.), but to change the T-shirt size you need to change your order. The size tables list the measurements for each size.

1. Go to your order page; you can find the link in your order confirmation. It looks like: https://pretix.eu/pysv/…/order/YOURORDERID/…/
2. Scroll to the bottom and select "Change or cancel your order → Change order" (German: "Bestellung stornieren oder umbuchen → Bestellung umbuchen")
3. Select another T-shirt size and continue to complete the change.

Edition I: up to five tickets per order.

The conference offers a Financial Aid and Scholarship Program to support those who would otherwise be unable to attend.

Please check the program page for this year’s deadlines and details.

No. Self-funded Tickets are intended only for private individuals paying out of their own private pocket and for researchers at public academic institutions. Tickets purchased by a company or organization will be canceled.

Any reference to a company or organizational address in the invoice details is considered misuse and will also lead to cancellation.

In this case, it is acceptable to purchase a Self-funded Ticket. Please ensure that no company or organizational information is included in the invoice details, as this would be considered misuse and may lead to cancellation.

Yes, a valid student-ID must be presented entering at the conference the first time.

Academic researchers affiliated with public academic institutions—such as public universities, or research organizations like the Max Planck or Helmholtz Institutes—are eligible to purchase a Self-funded Ticket.

This option is not available for researchers working in private institutes, research companies, or the public sector.

Please note that, for logistical reasons, Self-funded Tickets do not display institutional affiliations on conference badges. If showing your affiliation is important, consider purchasing a Standard Ticket instead.

Yes. In addition to credit card payments processed via Stripe, tickets can also be paid by bank transfer through the ticket shop. Please select the bank transfer option during checkout.

All funds must be received within 10 working days and at least two weeks before the conference; unpaid tickets will be canceled automatically. If issues persist with credit card payments, please contact your bank or try again later, as temporary authorization issues can occur.

After completing the purchase, all relevant information and documents, including the invoice, will be sent by email from our ticket shop Pretix. The invoice email includes a link where the invoicing address can be added or edited.

The invoicing address is often required by employers to claim VAT. Please ensure that the correct invoicing details (e.g., employer information) are entered before the conference starts. Changes to invoices cannot be made after this period.

Tickets are personalized and reselling is not permitted.

However, it is acceptable to purchase tickets on behalf of a friend, colleague, or subsidiary, provided proper reimbursement is handled privately.

No, badges issued are valid only for the person to whom the badge was assigned to.

Yes, please contact sponsoring.

Tickets can be canceled until 2 April 2027 directly through the ticket shop using the self-service option provided in the confirmation email. Please follow the link in that email to manage or cancel the ticket.

If assistance is needed, the contact form below can be used. Include the full name and ticket number (e.g., TCK5-1). Refunds are exclusively issued to the same payment method used for the original purchase.

Refunds are free of charge when issued to credit cards, PayPal, or SEPA accounts (EUR accounts within the European payment area). For international bank transfers (SWIFT), any bank fees incurred must be deducted from the refund amount.

Yes. If your visa application is rejected, you can cancel your ticket and get a refund at any time before the conference.

Until 2 April 2027, cancel directly through the ticket shop using the link in your confirmation email.

After that date, send a message to Tickets via the contact form and include your name and your five-character order code (e.g. ABC12). We will reply by email and ask you for a copy of your visa rejection.

Social Event tickets cannot be canceled directly through the ticket shop. Please contact us via the contact form — we are happy to cancel and reimburse them until 2 April 2027.

Yes, we do issue a certificate of attendance. These will be sent out after the conference via email.

See the Call for Proposals for more information and the milestones above for submission deadlines. We also offer exclusive speaking opportunities to sponsors, see sponsoring.

Each accepted proposal includes one complimentary conference ticket, to be used by any one speaker on that proposal. While we don’t provide speaker travel funding, financial aid is available for attendees who need support with travel and accommodation. If you’d like to be considered, please apply before the programme closes (see milestones above).

We understand that individual situations can be difficult. However, in general, we do not make individual exceptions for speakers who have not secured financial aid, as we want to apply the same rules fairly and consistently to everyone.

The program will feature a mix of keynotes, talks, workshops, panels and community sessions, tailored to offer diverse perspectives and practical insights. While the final lineup will be shaped by the submissions we receive during the CfP, our goal is to create a balanced and engaging schedule that reflects the latest trends and innovations.

There will be 90-minute tutorials on conference days. The attendance is included in the ticket but seats are limited.

Please note that tutorials take place at the Business Development Center Heidelberg (BDC), a ten-minute walk from the main venue. Use the adjacent 30-minute coffee breaks to switch venues.

Remote presentations are not accepted.

All speakers are required to present their sessions on site. Absolutely no exceptions.

Each accepted talk proposal includes one complimentary conference ticket for the primary speaker. Co-presenters are kindly asked to purchase their own tickets.

For accepted tutorials, up to two complimentary tickets are provided if both speakers are actively contributing to the session.

Participation in additional activities (e.g., social events) requires a separate purchase.

Got your talk accepted after buying a ticket? We refund it, and you keep your edition and shirt. The same applies to volunteers and organizers.

The conference website is static and regularly synchronized with data from Pretalx. Updates may take some time to appear, so a short delay is normal.

Please note that all information updates must be made directly through Pretalx. Requests sent by email or to the helpdesk cannot be processed.

Internet access during talks is not guaranteed. Presentations should not rely on a stable internet connection.

While efforts are made to ensure good WiFi coverage, performance may vary and cannot be guaranteed. Use of the conference network is at the speaker’s own risk.

A maximum of two speakers can be listed per talk proposal due to technical constraints. Please don’t add more than two speakers.

Please make sure all speakers (including co-speakers) are listed on the proposal before the CFP closes. Once the CFP has closed, we can’t add or change speakers. This helps us keep the review process fair and consistent, and ensures we can confirm speaker details, scheduling, registration, and accessibility needs in time.

A lightning talk (LT) is a short presentation which must not be longer than five minutes.

You may talk about / present (almost) everything with certain boundaries:

1. no promotion for products of companies
2. no call for 'we are hiring' (but you may name your employer)
3. conference or community event announcements are limited to one minute only
4. one LT per person per conference policy

Yes. Talks and tutorials are streamed and recorded.

Other formats, such as Masterclasses, Discussion Sessions, Roundtables, Topic Clinics, or Birds of a Feather (BoF), are neither streamed nor recorded.

During the conference, all talks are available as a livestream through our video app. Access requires a valid on-site or remote ticket.

Yes. We plan to deliver rough cuts of all talks overnight, so you can watch or rewatch sessions in our video app the next day.

Yes. All talks and their recordings remain available to ticket holders in our video app after the conference ends. A public release of the recordings is planned approximately three months after the conference.

Early access to video recordings before the public release is available to sponsors on request only.

We believe that open communication, meaningful conversations, and the exchange of ideas are more important than ever. That’s why we’ve introduced dedicated Discussion Sessions to our conference program.

Unlike traditional talks, these sessions are all about interaction. Whether it’s a roundtable discussion, a topic clinic, or a Birds of a Feather (BoF) gathering, the focus is on sharing experiences, exploring different perspectives, asking questions, and learning from each other.

These sessions will not be recorded. We want to create an environment where participants feel comfortable speaking openly, asking difficult questions, sharing unfinished ideas, and discussing challenges without worrying about being recorded or quoted out of context.

There are no slides required, no formal presentations, and no expectation of having all the answers. Just a topic, a group of interested people, and the opportunity for meaningful exchange.

Come with questions, ideas, experiences, or simply curiosity. Everyone is welcome to contribute.

Please contact us via the link below.

All sponsoring package prices are net plus statutory VAT in the amount valid at the time. VAT for sponsoring is subject to the EU reverse charge system, please provide your VAT number.

All entrances are step-free, eight lifts connect the event levels, and the handrails carry tactile orientation information.

The HCC is one minute from Heidelberg main station. The tram and bus stop "Hauptbahnhof Süd" is right in front of the venue, and the barrier-free car park P21 HCC is on site. Detailed information can be found on the venue’s website.

The conference team is happy to assist with accessibility needs and will make every effort to ensure the event is as accessible as possible. Please use the contact form to share specific requirements in advance so that appropriate arrangements can be considered.

We are fully aligned with public health recommendations and local regulations to ensure a safe and welcoming environment for everyone.

We kindly encourage anyone feeling unwell to refrain from attending in person. To make sure no one misses out, we provide free remote access to all on-site participants, allowing them to engage with the event from the comfort of their homes if needed.

We also warmly welcome and support attendees who choose to wear masks during the event, respecting individual preferences and fostering a culture of care and mutual respect.
