Anatomy of a Term Sheet (Seed / Pre-Series A) – What Really Matters
Thu, Mar 5, 5:30 PMGreat to see how much interest and engagement there was around our last session on the Convertible Loan Agreement – thanks to everyone who joined and asked so many thoughtful questions 🙌 Given that momentum, I’d love to continue the series with another practical, founder-focused meetup in Berlin in \~4 weeks: 🍕 Pizza & 🍺 beer & 🍷wine 🤝 relaxed networking 🎓 a 30-minute practical intro session: **“Anatomy of a Term Sheet (Seed / Pre-Series A)”** (no legalese, no theory – just what actually matters in practice) We’ll look at questions like: – valuation vs. real economics – liquidation preference & participation – option pool mechanics – control rights, vetoes, and board setup – common red flags and negotiation traps After the short session, plenty of time to hang out, meet people, and exchange war stories. Looking forward to seeing many of you in person again soon. 🚀

12MIN.ME | BERLIN | STARTUP #1.2 🚀
Thu, Mar 12, 8:30 AM**🚨🚨🚨 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. 📅 **The series at a glance** [12min.me](http://12min.me/) STARTUP consists of three independent sessions.
