The take
Equity Gap is not a fund in the usual sense. It is a member-led angel syndicate, founded in Edinburgh in 2010 by Jock Millican after a career mostly in brewing, where roughly 150 individual investors (an angel is someone writing personal cheques into young companies) pool their picks into early-stage Scottish businesses. That structure has made it one of the most active angel groups in the UK.
Equity Gap backs companies almost nobody else will look at yet: pre-revenue Scottish startups with a validated product, usually eligible for SEIS and EIS (UK tax-relief schemes that soften the risk of very early bets). It rarely invests alone, instead stacking its members' money alongside Scottish Enterprise, the Scottish National Investment Bank and other syndicates so a small seed round can reach a meaningful size. Its book runs across life science, food and drink, software and clean tech.
Equity Gap is not a water investor by mandate, and the way water shows up in its portfolio is the interesting part. Of the companies it has backed, two are water plays, across three deals: SeaWarm, a University of Edinburgh spin-out pulling low-carbon heat out of rivers, lochs, seawater and minewater, and MiAlgae, which grows omega-3-rich microalgae on the leftovers of whisky distilling and was an Earthshot Prize finalist in the Revive Our Oceans category.
Equity Gap is a useful marker for where water capital actually starts: not a specialist water fund, but a regional angel syndicate writing the first Scottish cheques into companies where water sits inside a climate or circular-economy story. For a newcomer mapping who funds water, this is the seed end of the pipeline, the stage before the dedicated funds ever show up.
