About Greensphere Capital

Greensphere Capital has been a leader in pathbreaking sustainable investment for over 15 years, most recently investing as a science-led growth equity fund investing in nature, biodiversity, and climate via the Gaia Sciences Innovation fund. We back exceptional companies solving commercial pain points across the land and ocean based economies. Our portfolio spans bioenergy, nature positive data infrastructure, sustainable forestry and urban regeneration.

We're a small, high-trust team. Everyone does real work and there is no room for stragglers.

Growth and opportunity

We are looking for a sharp, organised finance professional comfortable with the detail to support the CFO of our portfolio companies and Managing Partner of the fund in a dual role which will give you exposure across SME and fund entities.

The role

The Finance Business Partner is to be the financial and operational backbone across both the fund and our portfolio companies, with exec leadership support. This is a broad, hands-on position - from setting up bank accounts for newly onboarded portfolio companies to liaising with fund administration, reviewing management accounts, invoicing, and payments across the Greensphere Capital and GSI portfolio.

You'll sit at the intersection of two reporting lines: working with our fractional CFO on portfolio company finance, and with the Managing Partner on fund administration. It's a role that rewards people who are genuinely on top of the details and don't need to be chased.

We operate across a number of related entities — fund vehicles, GP entities, operating companies, portfolio co-invests — and you'll be across all of them.

We're open to a contract or FTE arrangement from the outset, moving into a permanent role — and to flexible hours for the right person.

Fund administration

– Liase with fund accounting and administration teams across Greensphere Capital.

– Review the management accounts, ensuring accuracy across both entities

– Keep track of the payment and invoicing cycle (Greensphere) Liaise with external accountants and auditors as required

You'll likely have

– Enough operational breadth to set up a bank account or sort a VAT query without waiting to be told how

– Comfort working across a web of related entities — fund vehicles, GP entities, operating companies, and portfolio co-invests — keeping each clean and never losing the thread

– Part-qualified ACA, ACCA, or CIMA — or equivalent experience that tells the same story

– Experience in a fund, investment firm, or PE-backed environment
