Finance as a Service

Institutional-grade finance leadership for funded, growing businesses, provided on a fractional basis.

We build and operate the finance function for funded technology, AI and software, and digital asset businesses, from the first management accounts through to board reporting and CFO-level strategy.

Ludgate Advisors Ltd is an ICAEW-registered firm.

The situation

The finance function after a capital raise

A capital raise brings new expectations from investors, boards and auditors. The finance function is typically required to mature more quickly than the wider team can grow.

Investors

Higher expectations

Investors expect timely reporting, a well-organised data room and financial information that withstands scrutiny.

Compliance

Audit & regulatory exposure

Audit thresholds and regulatory obligations are often reached earlier than anticipated, and preparation needs to begin well in advance.

Operations

Scaling operations

Growth brings more people, transactions and entities. Processes and controls designed for an early-stage business generally need to be rebuilt.

Strategy

Higher-stakes decisions

Decisions on hiring, runway and pricing carry greater consequence and benefit from senior financial input.

Many growing businesses do not yet require a full-time CFO. A fractional finance function provides senior expertise while accountability remains with the board, and allows a permanent appointment to be deferred until the business requires it.


Who we work with

Funded and growing businesses

Our clients have typically raised external capital, or reached a scale at which the finance function requires dedicated senior attention.

01

VC-backed tech scaleups

From Seed to Series B and beyond: board reporting, runway management and investor-grade financial information from the first funding round.

02

AI & software companies

Financial discipline that keeps pace with rapid product and revenue growth, without the cost of a full in-house finance team.

03

Digital assets & Web3 ventures

Protocols, funds and token issuers requiring specialist digital asset accounting, delivered to the standards expected in traditional finance. See our specialism →

04

Scaling operating businesses

Funded businesses that have outgrown basic bookkeeping but do not yet require a full-time CFO.

05

Firms seeking FCA authorisation

Cryptoasset firms, stablecoin issuers and other financial services firms preparing the financial and prudential elements of an FCA application.

What clients say

"Aaron was a great sounding board and helped put robust financial systems in place for us. Would highly recommend him."

Specialism

Digital asset finance

Cryptoasset and Web3 businesses raise accounting and finance questions that many practices are not equipped to address. We have built and operated finance functions for protocols, funds and token issuers.

Accounting

Crypto-native accounting

On-chain transaction accounting, wallet and exchange reconciliation, and multi-token subledger construction. Treatment under FRS 102, IAS 38 revaluation, and the US GAAP fair-value model introduced by ASU 2023-08, with the disclosure positions to support each.

Treasury

Token economics & treasury

Token model and incentive design, treasury structuring for protocols, DAOs and funds, and the accounting and control framework required to support an on-chain treasury through audit.

Tax

Tax & regulatory structuring

R&D tax credit claims for crypto and deep-tech teams, employee token warrant and option structuring, employment-related securities reporting, and UK corporation tax treatment of digital assets.

Advisory

Tokenised asset advisory

Structuring support for tokenised real-world assets, from perimeter scoping through phased delivery, working alongside regulatory counsel on authorisation questions.

Digital asset engagements are delivered to the same standards of rigour that apply across all of our work.


Track record

Selected engagements

A selection of engagements led by our founder, Aaron Scrupps, including work carried out before Ludgate Advisors was founded. Client details anonymised.

SectorDigital assets · crypto staking
ChallengeA pre-revenue crypto business with no finance function, on-chain activity no standard ledger could record, and an institutional client base that would eventually demand audited numbers.
What was builtA complete outsourced finance function from incorporation: bespoke tooling translating on-chain activity into fiat general ledger entries, crypto and fiat payroll, direct and indirect taxes, statutory accounts and external audit liaison.
OutcomeCarried from pre-revenue to $4bn AUM and through a Series C acquisition in 2024, including working capital and tax input on the SPA. Still the engagement lead, now reporting into group finance in San Francisco.
SectorEnterprise AI · subsidiary of a global technology group
ChallengeA research spin-out acquired by a multinational, required to produce group-standard reporting, consolidation packages and audit-ready numbers it had never had to produce before.
What was builtMonth-end close rebuilt to the group timetable, quarterly global consolidation packages, internal financial controls designed and implemented, and Tier 1 external audits run end to end.
Outcome£760k of R&D tax credits secured, plus a further £1.55m of direct tax savings identified from exemptions arising on the acquisition.
SectorAgriTech SaaS · VC-backed
ChallengeRaising growth capital without an investor-grade financial model, and board reporting that had no connection to the commercial pipeline.
What was builtThe financial model and investor deck financials for the raise, then a board pack whose KPI data feeds directly from the CRM, built with the operations and GTM teams.
Outcome£5m raised through convertible debt from VC and angel investors, with board reporting now running off live pipeline data.

The model

A single senior lead, supported by specialist partners

Each engagement is led end to end by one of our senior finance leads, each of whom has run finance functions within scaleups and is personally accountable for the work. Our leads are supported by a named bench: gunnercooke LLP for legal, regulatory and corporate counsel, and accounting delivery partners for bookkeeping, payroll and statutory compliance, all working under the lead's oversight. On FCA authorisation projects, we work alongside gunnercooke's regulatory lawyers to provide a combined legal and financial offering.

You
Ludgate: your senior finance leadPersonally embedded · end-to-end oversight
Legal partnerRegulatory, corporate & tax advisory
Accounting partnerBookkeeping & compliance delivery
Legal

Legal & regulatory counsel

Corporate, commercial and regulatory advice; authorisation and perimeter questions handled by specialists when they arise.

Tax

Tax advisory

R&D tax credits, EMI/CSOP scheme structuring and HMRC valuation, corporation tax plus sector-specific treatment.

Corporate

Corporate & fundraising

Fundraising mechanics, convertibles and ASAs, governance, data protection and financial-crime controls.

Delivery

Accounting & compliance delivery

Bookkeeping, payroll and statutory compliance capacity through named delivery partners, executed under your lead's personal oversight.

Each finance lead works with a deliberately limited number of clients, so that every engagement receives sustained senior attention.
