What ShareIn does

ShareIn Limited is an Edinburgh-based, FCA-authorised fintech (FCA reference 603332) founded in 2013 that provides white-label investment platform infrastructure for alternative finance operators in the UK. It serves FCA-authorised firms, energy and renewables platforms, property and real estate investment platforms, and impact/ethical investment platforms, powering regulated direct investment channels end-to-end — from investor onboarding and ID verification through deal listing, fund-raising, ISA wrapping, client money custody and post-investment portfolio management.

The company's core technology is a Microsoft-stack platform (ASP.NET MVC, .NET 4.7, .NET Core, SQL Server on Azure, with Vue.js, React and ReactNative front-ends) comprising three integrated products: the ShareIn Investment Platform (onboarding, fundraising, deal management, share certificates), ShareInPay (API-first CASS-compliant client money and payments since 2019), and the HMRC-authorised ISA Manager (Cash, S&S and IFISA since 2016). Compliance, KYC, appropriateness testing, 24-hour cooling-off, CASS daily reconciliation and HMRC reporting are built into the engine. Public APIs (ISA API and ShareInPay) plus a Switch ISA Manager service handle platform and ISA migration, including multi-year historical data.

ShareIn earns revenue from monthly platform licence fees, activity-based variable fees, Appointed Representative income, IFISA Manager fees, ShareInPay pay-in transaction fees (0.25% scaling to 0.10% above £10M monthly volume) and bespoke development work. Customers include Octopus Energy Collective, Aprirose, Abundance Investment, Ethex, Energise Africa and Triodos Crowdfunding, with £700m+ processed across 200k+ investors.

Direct peers

• Seccl: Seccl is a UK-based B2B platform technology provider offering custody, trading, and reporting infrastructure to investment managers and platforms. Like ShareIn, it powers white-label investment experiences for regulated firms and competes head-to-head in the UK adviser/platform infrastructure market.
• Third Financial: Third Financial provides platform technology for UK wealth managers and financial advisers, including client portals, trading, and back-office workflows. It is closely comparable to ShareIn as another UK-focused B2B platform serving FCA-authorised investment firms with similar white-label infrastructure.
• Transact (Integrafin): Transact, owned by Integrafin, is one of the UK's largest wrap platforms serving financial advisers and their clients with regulated investment infrastructure and portfolio servicing. It is comparable to ShareIn in providing FCA-compliant investment infrastructure, though it is more established and adviser-focused.

Broad incumbents

• FNZ: FNZ is a global, well-capitalised B2B wealth management platform serving large financial institutions with end-to-end investment, custody, and administration infrastructure. As a much larger incumbent with broader product scope, FNZ represents both a competitive threat and a possible exit benchmark for ShareIn's category.
• Avaloq: Avaloq (now part of NEC) provides digital banking and wealth management platform software to global financial institutions. It operates at a much larger scale and broader scope than ShareIn but competes for the same category of regulated investment platform spend among banks and asset managers.

Emerging players

• WealthOS: WealthOS provides a modern, API-first investment platform for wealth managers, fintechs, and asset managers. It overlaps directly with ShareIn's white-label, API-driven approach and represents a newer, well-funded entrant targeting a similar buyer profile in regulated investment infrastructure.
• Crowdcube: Crowdcube is one of the UK's leading equity crowdfunding platforms and a participant in the same alternative finance ecosystem that ShareIn serves. While it operates its own platform rather than selling infrastructure, it shapes the competitive landscape for ShareIn's clients and benchmarks investor expectations in the segment.
• Funding Circle: Funding Circle is a UK-based alternative finance platform operating in business lending and historically peer-to-peer lending. It sits in the same alt-finance category as ShareIn's clients and represents a benchmark for capital deployment volumes and platform operating scale in the segment.

Others

• GoCardless: GoCardless is a UK payment infrastructure provider for direct debits and recurring payments. It is relevant to ShareIn through ShareInPay and the broader payments layer of investment platforms, though it serves a different buyer and use case than ShareIn's core offering.
• TrueLayer: TrueLayer provides Open Banking APIs used by fintechs and platforms for account verification and instant payments. ShareIn's Energise Africa rebuild integrated Open Banking functionality, making TrueLayer an adjacent infrastructure provider within ShareIn's broader payments and onboarding stack.
