Sustainable Ventures Research
Investment Thesis
Sustainable Ventures describes itself as "the home of climate tech," building Europe's largest climate tech ecosystem from a base of coworking hubs, accelerator programmes, and direct capital. Founded in 2011 by Andrew Wordsworth and Christopher Morris, the firm backs early-stage climate technology companies with the potential to deliver both venture-scale financial returns and measurable environmental impact. Its EIS/SEIS-qualifying funds target companies addressing one or more of six strategic sustainability objectives, spanning decarbonisation of energy, transport, buildings, and industry.
Sector Focus
The firm invests exclusively in climate tech and the broader green economy, with a portfolio spanning:
- Energy efficiency and renewable energy (Airex, Global OTEC, Riding Sunbeams, Solivus)
- Circular economy and alternative materials (Notpla, Biohm, Ocean Bottle, Bundlee)
- Food waste and sustainable food systems (Winnow, Entocycle)
- Mobility and logistics decarbonisation (Pedal Me, Oxwash)
- Climate data, policy, and software tooling (Climate Policy Radar, Open Climate Fix, Subak, Guru Systems)
- Offshore renewables and marine technology (Rovco, Global OTEC)
Stage Focus
Sustainable Ventures invests almost entirely at pre-seed and seed, structured around SEIS and EIS tax-advantaged qualifying investments. Companies typically enter via one of the firm's cohort-based accelerator programmes (Sustainable Accelerator, National Climate Tech Accelerator, regional programmes in Manchester, Glasgow, Belfast and Cambridge) and receive an intensive 12-month programme of 1:1 support alongside capital.
Check Size
Publicly reported figures put typical initial cheques in the range of roughly £150,000-£350,000 per company, consistent with SEIS/EIS-qualifying early-stage rounds. The firm also facilitates non-dilutive funding (grant-writing support and R&D Tax Credit assistance) alongside its equity cheques.
Lead Tendency
As the accelerator/first institutional cheque for most portfolio companies, Sustainable Ventures typically leads or is the sole investor in the initial round, then supports the company through subsequent follow-on raises from other investors.
Recent Activity
The firm is actively deploying multiple concurrent vehicles: the IUK EIS Impact Fund (tranche closing 2026-08-24), and both the EIS Impact Fund and SEIS Impact Fund (tranches closing 2026-09-30). It is also accepting applications for its 8th accelerator fund. Recent organisational milestones include the appointment of Clare Hayward MBE as Non-Executive Chair (November 2025), lighting group Signify joining as a corporate partner (November 2025), and a flagship partnership with the University of Liverpool to launch the Sustainable Futures Accelerator for academic spinouts (April 2025).
Portfolio Highlights
The ecosystem spans 1,000+ startups with 62+ formal portfolio companies and reports £1.2bn in equity funds raised by portfolio companies and 7,000+ jobs created. Standout performers cited by the firm include Rovco (subsea robotics for offshore renewables, 13x valuation uplift) and Airex (smart energy bricks for social housing, >3x uplift on follow-on funding). Other notable portfolio companies include Notpla (seaweed-based packaging), Winnow (food waste reduction software), Ecologi (climate action subscription platform), Ocean Bottle, Oxwash, Entocycle, Pedal Me, Guru Systems, Open Climate Fix, Climate Policy Radar, and Subak. The firm reports an 87% portfolio survival rate and £175M+ in follow-on funding raised across its portfolio to date, with three exits exceeding £150M in enterprise value.

Decision Process
Investment decisions are made by a partnership/investment committee structure typical of an institutional accelerator fund, with cohort selection running through structured application and diligence processes for each accelerator intake rather than one-off partner sign-off.
Founder Preferences
The firm favours early-stage, often first-time or academic-spinout founders building venture-scale climate solutions, and is set up to support technical/scientific founding teams (e.g. university spinouts) that need structured commercialisation support alongside capital.
Geographic Focus
Primarily UK-based, with hubs and accelerator programmes in London (headquarters), Manchester, Glasgow, Belfast, and Cambridge. The firm positions itself as Europe's leading climate tech ecosystem and works with regional and national partners (including Barclays Eagle Labs and Innovate UK) to extend coverage across UK regions.
