02/ overview
The shape of fractional work in this market.
London is Europe's largest startup ecosystem — around $15bn of funding a year and 40+ unicorns (Dealroom, 2026) — and its startups and scale-ups create a steady run of executive openings.
The city's unique combination of financial expertise, technology talent, regulatory sophistication, and global connectivity makes it a magnet for high-growth companies.
Shoreditch, King's Cross, and Canary Wharf form the heart of London's startup geography, each with distinct characteristics.
The ecosystem spans from university spinouts in Imperial and UCL to mature scale-ups preparing for IPO, creating opportunities across all growth stages.
Seed/Series A companies often need fractional executives to access senior expertise without full-time costs.
Series B/C scale-ups require permanent and interim leadership to manage rapid growth.
Late-stage companies offer IPO-prep and international expansion roles with significant equity upside.
03/ rates
Published bands only, each with its source. Type your own day rate to see where it sits.
UK-wide published bands, not London-specific. Equity, where offered, is negotiated role by role; we don't publish a range we can't source. See the CFO, CTO and CMO hubs for detail.
04/ by function
What hiring teams and candidates need to know, function by function.
05/ startup experience
Founders who want a fractional executive who understands the UK startup ecosystem usually mean something specific: someone who has done the job inside a venture-backed company, knows how UK rounds are put together, and can talk to investors without a translator.
Senior experience in a large company is valuable, but it is not the same thing.
Test for it directly.
Ask which rounds a candidate has worked through and in what role; whether they have prepared a company for the SEIS and EIS venture capital schemes, including HMRC advance assurance; and how they read the funding market you are raising into.
The British Business Bank's Small Business Equity Tracker tracks UK equity finance by stage, sector, nation and region, and a candidate with real startup experience should be able to talk you through the trends it describes.
In the capital, London & Partners, the city's growth agency, runs free support programmes for London small businesses and scale-ups.
Then check the ground truth: references from founders, not only from investors.
For roles outside London see fractional jobs for startups; the fractional CTO and fractional CFO hubs cover those two roles in detail.
06/ startup finance
Startup finance jobs in London run from a first finance hire who keeps the books and payroll in order, through a finance director who owns forecasting and the board pack, to a CFO who leads fundraising and investor relations.
Early-stage companies often cover the senior end part-time with a fractional CFO, and hire full-time as the finance function grows.
What startups look for: a professional qualification from ICAEW, ACCA or CIMA; experience of a funding round, including investor due diligence; and the tax work early companies depend on, from the venture capital schemes above to R&D tax relief claims and, for a company holding a grant from Innovate UK, the UK's innovation agency, the reporting that comes with it.
Candidates who have built a model a board trusts, and then been held to it, stand out.
Published UK fractional CFO bands are in the rate table above (FD Capital, 2026).

Practical guide · Updated
A London startup role needs a clear explanation of the work, the organisation’s stage and the practical attendance requirement. Compare fractional, interim and permanent briefs against those conditions rather than assuming every startup needs the same seat.
The working brief · 01
Startup titles can carry a broad remit. Ask what already exists and what the person is expected to build, because those are different jobs even under the same title.
Current position
Ask about customers, operating processes and the team already doing the work. Keep stated facts separate from assumptions about the company’s stage.
Immediate responsibility
Name the decision or delivery gap the role addresses. Ask which other responsibilities remain with the founder.
Available support
Ask about people, budget and systems. An ambitious remit needs explicit resources or an honest explanation of what is missing.
The working brief · 02
A startup can have recurring leadership needs, transition work or a continuing seat. The workload and decision rhythm should explain the choice of engagement.
Fractional
Test whether responsibility can be held on planned days with cover between them. Agree how founders and team members raise decisions.
Interim
Define the gap or change and how continuity will be maintained. Confirm availability and the handover to a successor.
Permanent
Define continuing ownership and the hours expected. Separate employment terms from any assumptions about startup flexibility.
The working brief · 03
A London-based employer may describe on-site, hybrid or remote work. Confirm the practical requirements before deciding that a role fits your location and calendar.
Office
Ask which activities need attendance, where the team meets and what travel is expected. “Hybrid” leaves these details open.
Remote
Ask about permitted location, time-zone overlap and access to systems. Remote does not necessarily mean work from any country.
Portfolio
Map attendance and recurring meetings against other commitments. Include preparation and travel in your capacity decision.
The working brief · 04
An executive can own a function only when decisions and approvals are clear. Use these questions to distinguish a delivery remit from a broad request to “help the founder”.
Delegated decisions
Ask what the person can decide without returning to the founder. Identify financial, people and product limits.
Retained decisions
Name approvals and responsibilities the founder or board keeps. Set a route for disagreements and urgent questions.
Review rhythm
Agree how progress and constraints are discussed. Record scope changes before a temporary task becomes permanent responsibility.
The working brief · 05
A startup application should explain relevant work and constraints. Acas guidance supports choosing against the actual role requirements; company-stage labels are not a substitute for those requirements.
Comparable work
Describe a situation with similar resources or ambiguity. Explain your own responsibility rather than presenting the company’s growth as yours.
Practical decision
Describe what you chose, the alternatives and the information available. Show how you worked with founders and colleagues.
Transferable work
Explain what the team could continue using: a forecast, process, decision log or product practice. Do not disclose confidential former-employer material.
The working brief · 06
Imagine a founder needing reliable cash visibility while a small team handles transactions. This invented brief illustrates how to choose a responsibility without assuming a funding stage dictates a title.
Control gap
If accounts and reconciliations are unreliable, define the preparation and control work first. Name the person who will maintain it.
Leadership gap
If the information is reliable but strategic cash or funding decisions lack ownership, define that leadership responsibility.
Capacity decision
Compare the recurring workload and urgency with fractional or continuing employment. The brief, resources and authority determine the search.
The working brief · 07
A role description and an employer’s proposed contract answer different questions. Confirm the terms and practical conditions that matter to your decision.
Pay
Use what the employer actually states. A market guide does not establish an offer, and an unstated rate remains unstated.
Hours and status
Confirm the hours, availability and engagement contract. Employment and tax status need separate consideration.
Responsibilities
Confirm the reporting line, access and authority. Resolve material differences from the advertised brief before starting.
The working brief · 08
When a role creates a new process, continuity depends on how the work is recorded. Plan stages around usable work rather than promising a fixed startup timetable.
Establish
Make repeatable
