Sessionize is the SaaS platform that turned the technical-conference CFP — call for papers — into a managed workflow. Organisers use it to run submissions, evaluate them in Stars / Yes-No / Comparison modes, build schedules, and handle speaker logistics. Speakers maintain a single canonical profile they then point at any Sessionize-powered event.
Thimo Buchheister's profile lives at sessionize.com/thimo-buchheister.
Why the platform matters
Sessionize is now used by thousands of events in 120+ countries — including most of the major Microsoft developer-community conferences. For a technical speaker the profile is no longer a nice to have; it's the resume conference organisers expect to read. It hosts the bio, the headshot, the talk catalogue, the social proof, and the previous-events history in a format CFP committees can evaluate at scale.
Practically: if your Sessionize profile isn't current, you're not in the pipeline.
What the profile says
From the live profile:
- Location: Ibbenbüren, Germany
- Current role: CEO, ThreeB IT GmbH (2019–present)
- Prior roles: CTO of All about Ashley GmbH (2004–2019); CTO of Xircuit GmbH & Co. KG (2017–2019)
- Bio line: "Organizer and speaker of a monthly .NET Meetup since 2017" — that's the Ibbenbüren .NET Meetup
Talk topics on the catalogue:
- .NET
- ASP.NET Core
- .NET MAUI
- .NET Backend
- ASP.NET Core Web API
- .NET Aspire
Sessionize domain-expertise tags:
- Business & Management
- Information & Communications Technology
- Media & Information
- Transports & Logistics
That last one — Transports & Logistics — is the deliberate part. The same domain expertise that anchors the customer work (Kühne+Nagel, customs and shipping document automation, the early Copernicus Hackathon entry) appears on the speaker profile, because the speaker profile should describe the company's centre of gravity, not just the buzzwords.
Why a profile, not a website
A Sessionize profile is transferable. It works across every Sessionize-hosted CFP — and the universe of those CFPs grows every year. Maintaining a single canonical profile beats maintaining one bio per conference, which is what the alternative looks like.
The same logic underlies the .NET Foundation bio: one authoritative source, kept current, linked from everywhere else.
How this connects to the rest
The Sessionize profile is the outbound version of what the Ibbenbüren .NET Meetup is inbound. The meetup brings the community in to us; Sessionize sends us out to the wider community. Both feed the same hiring funnel and the same credibility signal.
If you're a CFP committee evaluating Thimo for a slot at your conference, sessionize.com/thimo-buchheister is the place to start.
