Greensphere Capital is a fund manager and the UK's largest female-owned venture capital firm, with more than 15 years at the forefront of pioneering sustainable investing. Gaia Sciences Innovation (GSI) is a science-led growth equity fund investing and scaling best in class profitable businesses that mitigate climate change and biodiversity loss. Alongside capital, Greensphere’s GSI fund provides its portfolio companies with shared operational infrastructure – including a Portfolio finance function – to help them build finance capability faster and more cost-effectively than they could alone. Portfolio companies range from fast-growing technology businesses scaling commercial operations across multiple entities and geographies, to smaller, earlier-stage teams still building out their finance function.
This is a broad, hands-on Financial Controller role, created to give portfolio companies across Greensphere's GSI fund the day-to-day financial management they need to scale – from setting up banking and finance infrastructure for newly onboarded companies, to reviewing management accounts and payments across the portfolio. You'll work closely with each company's CEO and GSI's Portfolio CFO and thrive on being genuinely on top of the detail without needing to be chased.
Time committed to any one company varies with its size and complexity – from a light monthly touchpoint up to three days a week for the most complex, multi-entity businesses – with the rest spent as embedded finance business partner across GSI's wider portfolio. You'll be comfortable as the primary finance resource across several businesses at once, moving between a month-end close, a board pack, and a bookkeeping tidy-up in the same week, and shaping how finance runs across a group of nature-positive businesses as they grow.
The responsibilities below apply across the portfolio, with the depth of involvement in each area scaling according to the time committed to a given company. Where up to three days a week are committed to a single investee company, the role covers the full range below in depth, including multi-entity and intercompany work where that company operates overseas subsidiaries. Where time committed is lighter, the same areas apply on a lighter-touch, proportionate basis.
Bookkeeping & Financial Control
Intercompany & Multi-Entity Accounting
Where a portfolio company spans multiple entities – for example a UK parent alongside overseas subsidiaries – managing intercompany cross-charges, ensuring these are correctly documented, consistently applied, and appropriately reflected in each entity's accounts
New Portfolio Company Onboarding
Setting up operational finance infrastructure for newly onboarded portfolio companies – including banking, entity set-up, financial processes, and insurance
