About us

From practice.
For practice.

flow present was not born in a pitch deck. It grew out of workshop rooms, conference hotels, and co-working spaces across four continents — from over twenty years of seminar-room experience, teaching ideals, technical precision and clarity, and the wish to finally have a tool that brings all of this together.

The people behind flow present

Two perspectives — one shared conviction that good tools make a difference.

Political educator · Media literacy educator
NGOs & associations Political education Media literacy

For over 20 years I have delivered workshops, seminars, and keynotes — for political education associations, large NGOs and government organizations, for unions and activists. Across four continents, in person, hybrid, and remote. Solo, in large teams, in small teams.

As a media literacy educator, I have tested over a hundred tools. Participatory ones, structuring ones, planning ones, evaluation ones. Open source. Proprietary. Comprehensive or highly specialized. For week-long seminars, for 15-minute lightning talks — and everything in between.

More about my background in education: daniel-seitz.org

All of this experience has flowed into one tool. flow present is the essence of all our experience — and that of many fellow practitioners and experts.

— Daniel Seitz, Co-founder

With flow present, we wanted to make delivering high-quality educational work structured, purposeful, and supportive at every stage — grounded in teaching ideals and genuine forms of participation.

Good software. Open source. Forms of participation that actually work. Good design. Good planning. All of this belongs together — and that is exactly what flow present brings together in one place.

I come from engineering. I am not an educator. Perhaps that is exactly why I am fascinated by the question of how good collaboration succeeds.

In my professional life I have learned that complex processes only work when they are simple, clear, and reliable. As a materials engineer, I work every day on processing highly critical materials under precise conditions — where mistakes have real consequences. That is the mindset I bring to flow present.

Good software should support people, not keep them busy.

Sustainability

We approach sustainability with professional expertise: co-founder Daniel Seitz is a sustainability manager for culture, education and media and a certified officer for sustainable event management (ISO 20121) — we examine every step within the company and in product development.

  • Digital sustainability through open source. The core will be released under AGPL-3.0 (opening planned after an independent code review) and self-hostable — it is meant to outlive any single vendor, stay auditable and maintainable, with no vendor lock-in. License & source code.
  • EU hosting powered by renewable energy. Data processed on EU servers (Frankfurt), powered by renewable energy; GDPR-compliant. Privacy.
  • Efficiency instead of tool sprawl. One tool replaces the chain of slide, polling and facilitation tools — fewer subscriptions, fewer redundant data copies, fewer resources.
  • Economic sustainability. Built for the long term, without investor pressure.

Made with Care

flow present stands on the shoulders of giants. Behind every module is the best available open-source software. All privacy-critical modules are built on highly regulated, proven systems — connected by carefully considered architectural decisions. The core of flow present will itself be open source (AGPL-3.0; opening planned after a code review): license & source code.

Before the open-source release, an independent code review is carried out. We develop test-driven: no module goes into production without tests. Privacy-critical functions run on Supabase — an ISO 27001-certified Postgres platform. All payments run entirely through Stripe. Both are proven worldwide and in use by millions.

Accessibility

Not an afterthought.
A foundation.

At flow present, accessibility is not a later requirement but part of the technical foundation — built in from day one, tested automatically, not patched in afterwards.

Access ⌨️
Screen readers & keyboard
Every view is designed for screen readers and full keyboard operation — with a well-considered semantic structure and live announcements for real-time content.
ARIA live regions
Contrast 🎨
WCAG 2.1 AA everywhere
All color combinations follow the WCAG 2.1 AA guidelines. Contrast is checked automatically with every brand customization — no manual rework.
Contrast ratio ≥ 4.5:1
Language 🌍
Live translation
The participant view can be translated live into more than 25 languages via LibreTranslate — open source, self-hostable. Original and translation side by side.
25+ languages · works on LAN
Motion 🎞
Motion sensitivity
Users who have enabled “Reduce motion” in their system settings automatically get a low-animation view. No exceptions.

Content 📋
Copyable & open
The live view for participants is deliberately pared down — easy to read, copyable, and open to browser translation tools. No vendor lock-in for content.

Tests
Automatically tested
axe-core runs in our automated test suite. Accessibility is checked with every change — not fixed “someday” after the fact.
axe-core in the tests
Accessibility is not a line item — it is included identically in every plan. We believe that good educational work should be open to everyone. That applies to the tools as well.
