BIV Monthly Update LXIII
BIV Monthly Update LXIII – 1/18/2026
“Perfect. Do it again.” Don Diego de la Vega, The Mask of Zorro
Highlights
Fantastic to be joined by so many of our LPs and broader network in Denver for the Mile High Splash and BIV Dinner in Denver. Steve did an absolutely unbelievable job as the MC. A sight to behold.
Articulating the next pillar of our strategy: Why We’re Building Our First Growth Fund. All feedback welcome. We’ve established Growth Fund I in response to the clear inflection point that has arrived in the water market: “The End of the Beginning - Financing in Water is Entering its Growth Era”.
Christine, Steve and I had 2 excellent days in Denver for our end of year Partner meeting. How lucky I am to work alongside these two colossal minds. Some important decisions made (deep breath….).
GREAT to have two days in Boston to kick off the year, the first with Cala Systems who have completed their Seed II and are oversubscribing to build inventory in the face of excess demand. Reach out if you want to meet Michael. I recommend it. The second was with the OCP Group and Bidra, alongside a bunch of other fun people (Wellington, Builders VC, Nuveen, and always great to see Craig from Aqua Membranes). Bidra are a wonderful LP.
A super Christmas in Scotland followed by a wonderful New Year and birthday in the very snowy Hudson Valley. Thank you Ruki for enabling (and preparing) everything.
