Yin: Nervous System Reset
In this Yin practice, we take time to pause, soften, and simply be. With the support of long-held, floor-based postures, the body gradually opens, accessing the deeper layers of fascia and energy pathways.
We allow gravity to guide the process. This subtle work calms the nervous system, nurtures stillness, and encourages quiet reflection. It's an opportunity to release tension from both body and mind, and to reconnect with yourself on a deeper level.
The class is led in English and is open to all levels.

Find the Essential Story of Your Family Tree! (First Steps in Metagenealogy)
Please join us at New Pages to take your first steps in discovering the essential story of your family tree.
Using the book *Metagenealogy: Self-Discovery through Psychomagic and the Family Tree* (Jodorowsky and Costa) as a guiding text, the hosts will help you put together the initial draft of your family tree so that you might learn the essential story you tell and live out in your life. You will then learn the next steps you should take to more fully fill out this story and to make the family tree your ally rather than your enemy.
Metageneaology seeks to combine art and science in order to help people create for themselves a meaningful life.
Why is this important? We all are in the process of living out some type of story we tell ourselves. Often, this story isn't something we created completely on our own, but is passed down to us via the family tree. It is important that we not only become aware of this story, but that we feel i*n control of it* rather than *being* *controlled by it*.
Please join us for the first ever session in this work that we have found immensely help for our own selves.
A note: please complete no preparatory work on your tree before the event. You need only bring yourself and perhaps your favorite pen.
Attendance is limited to 9 people to allow for adequate time to focus on the discovery and building of each person's tree. Please, if you RSVP and then change your mind, change your status so that another person might be able to join.
*The event is free, but a modest donation helps us continue to offer events in the future.*

12MIN.ME | BERLIN | STARTUP #1.2 🚀
**🚨🚨🚨 ATTENTION: we moved to luma. please RVSP [HERE](https://luma.com/12min.me_Berlin)🚨🚨🚨**
# [12min.me](https://12min.me/) START UP is a brand new morning format for bold ideas and fresh perspectives
Berlin Startup Community, we’re launching something new.
Together with betahaus, we’re bringing the [12min.me](http://12min.me/) spirit into the morning.
[12min.me](http://12min.me/) STARTUP is a three-part breakfast series, embedded in the well-known betabreakfast format.
Instead of three speakers in one evening, we do things differently.
One morning. One speaker. One focused impulse.
12 minutes. One voice. Zero fluff.
Join us for the first edition of [12min.me](http://12min.me/) STARTUP, a compact morning session for founders, operators, creatives and everyone building things that matter.
**✔️ What to expect**
* One inspiring startup-related talk
* 12 minutes of sharp insight
* Curated exchange over breakfast
* The familiar [12min.me](http://12min.me/) energy, just earlier in the day#
🚀 **The formula stays the same**
* 12 minutes talk
* 12 minutes of Q&A
* 12 minutes of networking
The familiar [12min.me](http://12min.me/) energy, just earlier in the day
**🎤 Our speakers**
**Speaker 1 @March 5**
**[Jonathan Hegel](https://www.linkedin.com/in/jonathan-beisiegel) from [FW Systems](https://www.linkedin.com/company/frachtwerk/)**
Jonathan is the CEO of FW Systems, a specialized system house for open source solutions and IT services with a fixed-price model. After years in traditional IT, where he regularly had to work night shifts due to emergencies, he decided to do things better—for customers and for IT professionals. Today, he help SMEs transform their IT from a constant work in progress to a reliable infrastructure they can depend on.
**Jonathan\`s talk: "How we are completely rethinking system administration as a service for your company"**
Companies cannot possibly do everything themselves. So things like accounting, logistics, and IT are outsourced to external service providers. In the IT sector, system houses have been doing very well for themselves in recent decades! Every little thing is charged for, and if there are any errors, the customer is expected to open a ticket. We are rethinking this! We are applying the “as-a-service” concept from Airbnb, Uber, and Everstox to system administration and taking responsibility. Jonathan will show how this works in his talk.
**Speaker 2 @March 12**
**[Anne Biedermann](https://www.linkedin.com/in/anne-biedermann/), independent wealth partner for women**
Anne has extensive experience across venture capital, single-family-office & HNWI investing, and early-stage operations. She works with investors who are building, inheriting, or stewarding wealth on how to allocate capital with clarity — particularly where venture capital intersects with long-term wealth strategy. Anne also invests personally, giving her a practitioner’s perspective on capital allocation decisions.
**Anna\`s talk: "Not All Capital Is the Same: Decoding Investor Behavior"**
Founders often assume all investors evaluate risk, timelines, and returns the same way and that assumption is costly. This session breaks down how funds, family offices, and individual investors actually make decisions, where founder–investor misalignment typically begins, and how founders can better position themselves for the right kind of capital, not just any capital.
**Speaker 3 @March 19**
**[Immo Ait Stapelfeld](https://www.linkedin.com/in/immoaitstapelfeld/), Co-Founder & CEO at [913.ai](https://913.ai)**
**"From Legal Complexity to Practical AI. How We Help Regulated Industries Use AI Without Losing Control"**
This presentation tells the story of Immo’s transition from a trained lawyer working in mass proceedings to an entrepreneur building AI products for regulated industries. His legal background, combined with hands-on experience as a founder, shaped a pragmatic view on AI. not as a disruptive replacement, but as a controlled and compliant tool. At[ ](http://913.ai)[913.ai](https://913.ai), this perspective enables conservative organizations such as insurers to enter the AI era in a way that respects regulation, responsibility, and existing teams while still unlocking real efficiency gains.

Berliner IT-Stammtisch für Freelancer vom DBITS e.V.
Hallo,
es ist wieder so weit, der zweite Freitag im März ist schon diese Woche. Deshalb habe ich im Neffes am Freitag Abend für uns den hintere Bereich reserviert und ich freue mich schon, euch wieder persönlich zu sehen!
Und hier der übliche Ankündigungstext:
Unser zweimonatliches Treffen steht wieder an!
An jedem zweiten Freitag eines ungeraden Monats treffen wir Selbstständige, Unternehmer und Freiberufler aus der IT uns wieder um 19:00 Uhr im Neffes.
Bei einem gemütlichen Zusammensein werden wir uns über fast alle Themen unterhalten.
Der Schwerpunkt liegt dabei auf den beruflichen Themen. Z. B. wie gehen andere mit den Kunden und deren Mitarbeitern um, was sind die neuesten Insider Infos von den verschiedenen Unternehmen, wie sieht es bei den anderen mit den Einsatzorten und Arbeitsbedingungen aus und vieles mehr.
Es wird wie immer ein interessanter Abend mit einem umfangreichen Erfahrungsaustausch werden, der einen auch beruflich weiterbringt.
Mit dem DBITS e.V. wollen wir die Anerkennung von IT-Freiberuflern in der Gesellschaft und Politik vorantreiben. Dort gibt es leider noch einen sehr großen Aufhol- und Aufklärungsbedarf und damit viel zu besprechen und zu erfahren. Des Weiteren bietet uns der Verein ein breites Netzwerk an Leuten mit den gleichen Zielen und Problemen.
Aber wie gesagt, das Ziel ist ein schöner, informativer Abend, es gibt kein Mitgliederzwang.
Nimm teil, ich freue mich schon auf Dich!
Viele Grüße und eine gute Zeit bis zum nächsten Freitag!
There Must Be a Lilac: EventStorming with Alberto Brandolini
He's back! The inventor of EventStorming is once again joining the Berlin Collaborative Modeling Meetup for an evening of massive learning, massive laughter, and no doubt a massive number of sticky notes.
Here is the agenda:
**Collaborative Reverse Roadmapping**
We'll put future events on a timeline to build the future we want to happen and make it tactically sound. We'll leverage ideas from
* EventStorming (surprise!)
* Futurespective
* Traditional planning
And we'll explore a tool that will enable strategic planning and overcome deadlocks.
This is a rare opportunity to spend time with a true thought leader in the DDD community and the person who contributed to the world the whole premise of our meetup. He's full of insights and stories, wit and wisdom, and we are lucky to have him drop by to share them with us. Don't miss this one!
**Please do not RSVP if you do not intend to come. For this event only, we have to limit attendance.**
As always, everyone is welcome. You don't need to be a software engineer to participate. In fact, it would be great to have more people who aren't software engineers. We're here to solve problems cross-functionally, not get into implementation details. As long as you care passionately about getting things right, then you belong here!
This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

**Presented by Leslie Kane, Founder of Why Not Today?**
**Wednesday March 25th \| 9:00 AM – 10:00 AM**
**Venture X Loudoun**
Join us for a powerful resource presentation designed to help entrepreneurs move from scattered effort to sustainable momentum.
***
## **About the Session**
Entrepreneurs rarely struggle because they lack ideas.
They struggle because everything lives in their head.
In this session, **Leslie Kane**, founder of **Why Not Today?**, will explore how developing intentional systems creates clarity, focus, and forward progress in business.
Drawing from decades of leadership experience and working with hundreds of entrepreneurs, Leslie shares how structure reduces overwhelm, simplifies decision-making, and transforms inconsistent action into repeatable success.
If you’re building a business and constantly feeling stretched thin, this conversation will challenge you to ask a powerful question:
**Why not today?**
***
## **What You’ll Gain**
* Insight into why systems are critical for growth
* Practical perspective on turning ideas into structured action
* A framework for reducing overwhelm
* A mindset shift from reactive to intentional leadership
This is not about adding more to your plate — it’s about building the foundation that allows your business to grow without burning you out.
***
## **About 1 Million Cups**
1 Million Cups is a national program that brings entrepreneurs and communities together to learn, connect, and grow through conversation and collaboration. Loudoun’s chapter meets on the 2nd and 4th Wednesdays each month.

Family Constellations workshop with Randy Goldberg
Family Constellation work is a powerful experiential process for discovering the hidden dynamics operating within families and systems. Often the struggles we carry—conflicts, repeating patterns, unexplained emotions, or blocks in life—are not only personal but connected to deeper, unseen loyalties in our family lineage. In a constellation workshop we learn to slow down and look at what actually is, without judgment or blame. By respectfully acknowledging forgotten or excluded members of a system, and by allowing what has been hidden to be seen, the deeper intelligence of the field begins to reveal unexpected solutions.
As order is restored, people often find themselves able to release burdens that were never truly theirs to carry. Unconscious entanglements between victim and perpetrator can soften, making space for dignity and understanding on all sides. Participants frequently experience a renewed sense of belonging—to their family, their life, and their place in the larger human story. Through the shared field of the group, movements toward resolution emerge organically, allowing individuals to step forward with greater clarity, strength, and freedom.
Randy Goldberg, LMT is a graduate of the DC Hellinger Institute, and of advanced studies in Family Constellation with Heinz Stark of Germany. He is a former Yoga monk, Craniosacral therapist, and a world-renowned astrologer (both Western and Vedic) interviewed by the Washington Post, NPR, and CNN. He has facilitated Family Constellation therapy for individuals and groups for more than 20 years. More information at www.randygoldberg.org ; 202-380-6850 or randygoldberg.org@gmail.com

Hacking the Stack: Using OpenSearch Dashboards as an Application Framework
**Agenda:**
* 6-6:30 pm: Networking and food/drinks
* 6:30-7:15 pm: Announcements and presentation
* 7:15 pm-7:30 pm: Q&A and close-out
**Hacking the Stack: Using OpenSearch Dashboards as an Application Framework**
Most developers treat OpenSearch Dashboards (OSD) strictly as a visualization layer—a place for charts and graphs. They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience.
Join us for a deep dive into the engineering reality of the OpenSearch stack, including:
* **The Analysis:** Why the OpenSearch stack beat out the competition.
* **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD.
* **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale.
* **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for.
**If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**
