etsaW Ventures

What etsaW Ventures does

etsaW Ventures is a London-based venture studio, founded in September 2022, that builds and backs companies focused on circular technology in material and waste innovation. The studio combines proprietary AI-enabled research and landscape-mapping tools with a venture-creation process (the Optimistic Innovation Programme, or OIP) to identify under-utilised waste streams, assess circular opportunities and launch or fund companies that commercialise the resulting technologies. It was founded and remains led by Nick Wall (CEO, ex-Tails Cocktails/Bacardi), Dr. David Greenfield (Exec Chair, RAEng visiting Professor and CIWM Junior Vice President), Sophie Thomas (CTO, formerly Director of Circular Design at Useful Projects and architect of the £35m RSA Great Recovery Programme), and Patrick Montague (Venture Advisor), with Isabelle Linden as COO and Bengt Jenvey Cousins as AI Entrepreneur in Residence. Advisory bench includes senior figures from PWC, Gowling WLG, the UK Office for Environmental Protection, the University of Exeter, Black Tomato and the Circular Economy Institute.

The studio operates a hybrid portfolio model: wholly-owned internal ventures (Salvortech, an AI-enabled marine bio extraction company), minority equity stakes with board seats in early-stage circular start-ups (15% of Uplift360 in aerospace composites recovery; 20% of MarinaTex in marine-derived packaging and agri materials), and a consulting-based service line (the Optimistic Innovation Programme) that delivers bespoke AI-augmented circular material action plans, market scans and workshops to corporate clients. Proprietary assets include research and landscape AI mapping, material security analysis tooling, lifecycle-analysis deep dives, and a Double Diamond-based innovation framework. The model is supported by ecosystem partnerships with the Circular Economy Club (7,000+ members across 140 countries) and the Circular Economy Institute (350+ alumni across 30+ countries) for talent, deal flow and client introductions.

Commercially, etsaW generates revenue (or expected revenue) through three streams: equity appreciation in portfolio companies, fees from enterprise engagements sold through the OIP, and potential licensing or transfer of technologies developed inside the studio. Go-to-market is direct, enterprise-field-sales style: bespoke OIP contracts are initiated via the website contact form and email, with a multi-year engagement cadence. Pricing is contact-based and undisclosed. Current revenue, ARR, funding-round totals and external investor identities are not publicly disclosed.
