Investor Room

The two tranche pages and the workbook are Pro Forma v81 (12 September 2026); the bridge note and the panel response are the v79 set of early September; the deck is v80 (the 7 September deck with Wave 1 accounts described rather than named). Headline figures are unchanged between them except where the v81 change log says so. The raise is $2.7M in three post-money SAFEs.

Provided to accredited investors under SEC Rule 506(b). Not an offer of securities. Figures are model-derived on stated assumptions; the workbook's README and change-log tabs record every assumption and every change since v70.
