<p><span style="font-size:10pt"><span style='font-family:"Times New Roman",serif'>V21 GmbH, founded in Hamburg in December 2019, develops ZeroCoreVac — a vacuum insulation panel made of two thin stainless-steel sheets held apart by high-strength aramid fibres, evacuated and welded so that almost no heat passes through, working on the same principle as a thermos flask but in a flat form. The company reports a thermal conductivity below 0.008 W/mK, roughly 3 cm of panel matching the insulating performance of up to 25 cm of mineral wool, plus non-combustibility, mechanical robustness (up to 60 t/m²) and a 50+ year lifespan.</span></span></p>
<p><span style="font-size:10pt"><span style='font-family:"Times New Roman",serif'>The business model is licensing-led: V21 makes small batches at its Hamburg R&amp;D facility for pilot projects now, and from 2027 plans to license production partners who pay a per-square-metre fee. Stated pilot partners are ConRail (refrigerated containers), MobilConcept (modular buildings) and EcoWorks (façade renovation). Initial target markets are modular/container construction and serial façade renovation, with later expansion to refrigerated logistics, seasonal heat storage, EV battery thermal management and conventional new-build.</span></span></p>
<p><span style="font-size:10pt"><span style='font-family:"Times New Roman",serif'>The technology has been independently tested by Fraunhofer ISE (Freiburg) at the prototype stage and supported by a DBU Green-Startup grant of EUR 125,000. The product is currently at TRL 5 (a working prototype validated in a relevant environment); this raise funds development toward TRL 7.</span></span></p>

<p><span style="font-size:10pt"><span style='font-family:"Times New Roman",serif'>V21's headline returns are set by the company, not derived from a sector heuristic. The company presents two scenarios from its financial plan, both assuming positive business development:</span></span></p>
<p><span style="font-size:10pt"><span style='font-family:"Times New Roman",serif'>The return is realised through the loan's interest mechanics rather than a share sale. Annual "success interest" depends on the company posting a net profit; "bonus interest" at the end of the term depends on the company's value at that point (measured by the most recent financing round within 12 months, or otherwise by the last year's revenue); and "exit interest" applies only if more than 50% of the company or its key assets are sold during the term. On the company's own figures, the base case shows losses through 2028 and the target case shows a first profit only in 2027 — so most of the projected return depends on the value and exit components, not on annual interest in the early years.</span></span></p>
