What Graphene does

Graphene Platforms Limited is a UK-based, FCA-authorised (FRN: 756360) infrastructure provider that enables wealth management firms to operate their own branded platforms on top of institutional custody rails rather than building or renting them. Its core product, the "Graphene Fabric," is a four-layer stack: a private Data Cloud (2.4M records, 48 connected sources, 99.9% uptime), an Investment Platform layer connected to SEI's $1.7T AUA custody ecosystem via the Wealth Gateway (multi-currency, multi-jurisdiction, 400+ product wrappers), a configurable Client & Adviser Experience Layer, and a Governance layer with embedded compliance and operations. The company was founded in 2015 by Kevin Mitchell and Robert Kelly, is headquartered in London with a second office in Edinburgh, and serves private banks, wealth consolidators / Top 100 IFA firms, discretionary fund managers, family offices, and IFAs managing between £500m and £10bn+ in assets.

Graphene earns revenue primarily through subscription-based infrastructure fees for access to its unified platform stack, supplemented by transaction-based fees for custody and execution connectivity routed through SEI. Pricing is bespoke and quote-based rather than publicly disclosed, structured around client AUM, modules selected, and firm size. The go-to-market combines direct enterprise field sales, inside sales, and channel partnerships with IFA networks and adviser platforms (Swissential, Tavistock, Futura, Blackfinch, Marlborough), with an embedded operations team model that delivers migration, onboarding, and ongoing service. The company claims 100% client retention, has acquired the Marlborough Select Platform (May 2025), and has received two strategic investments from SEI Ventures (October 2025, February 2026) alongside a strategic partnership with SEI Investments (Europe) Limited that anchors its custody infrastructure.

Core offering

Graphene provides institutional-grade Infrastructure-as-a-Service for wealth management firms, unifying Private Data Cloud, an Investment Platform built on SEI's $1.7tn custody ecosystem, a Client Experience Layer, and embedded Governance services into a single modular Fabric. The platform enables private banks, DFMs, consolidators, family offices, and IFAs to operate their own branded wealth platforms with full data sovereignty, without building proprietary infrastructure in-house.

Product overview

Graphene is a unified, institutional-grade wealth management platform infrastructure comprising four integrated layers: the Data Cloud (private dedicated data environment with full sovereignty, supporting 2.4M records from 48 sources at 99.9% uptime), Investment Platform/Wealth Platform Gateway (connecting to SEI's $1.7 trillion custody ecosystem with multi-currency settlement and 400+ product wrappers), Client Experience Layer (branded adviser and client portals with configurable workflows and Document Composer), and Governance Services (embedded operations team, compliance monitoring, audit trails). The platform targets private banks, wealth consolidators, discretionary fund managers, and IFA networks managing £500m to £10bn+ in assets. Service modules include custody and execution, onboarding/KYC, portfolio management with FIX connectivity, performance/tax reporting, wrappers and retirement products, and compliance oversight. The architecture enables firms to operate their own branded wealth platform without building infrastructure themselves.

Scale indicators5 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Finastra: Major financial software provider with retail, corporate and wealth platform capabilities. Adjacent rather than directly comparable, but a likely overlapping incumbent as wealth firms consider unified platform alternatives.
• SS&C Advent: Portfolio management, reporting and accounting software suite (Advent APX, Geneva) serving asset managers, hedge funds and private wealth firms globally. A broader incumbent with overlapping portfolio management, reporting and compliance modules.
• SEI Investments: Nasdaq-listed incumbent providing the SEI Wealth Platform and $1.7tn custody infrastructure that Graphene is built on top of. A powerful partner but also a potential competitor — its Wealth Platform competes broadly with what Graphene enables clients to own.

Direct peers

• Profile Software: Provides Axia wealth management platform and investment management solutions to private banks, asset managers and family offices in the UK and Europe. A close direct competitor in the modular wealth platform infrastructure space.
• FNZ: Global wealth management platform technology provider serving asset managers, advisers and private banks with end-to-end platform infrastructure. Closest direct competitor to Graphene's "platform ownership" proposition, though FNZ typically operates at much larger scale and provides the platform itself rather than positioning as an infrastructure layer.
• Bravura Solutions: Wealth management and transfer agency platform provider serving superannuation, life insurance and wealth firms. Comparable as a technology platform to financial institutions, though with broader geographic and segment reach than Graphene.
• Avaloq (NEC Software Solutions): Core wealth and digital banking platform vendor serving private banks and wealth managers globally (acquired by NEC). Directly comparable offering to Graphene Fabric for wealth platform infrastructure, particularly in private banking segments that Graphene targets.

Others

• Tavistock Investments: UK wealth and asset management group that is both a Graphene partner and an adjacent competitor. Worth noting because it is listed on Graphene's partner page, illustrating the channel-partner GTM dynamic.

Regional players

• Clearwater Analytics: Public US-based investment accounting and reporting platform increasingly expanding into UK/European private wealth. Comparable in investment operations, reporting and data accuracy, though typically serving larger institutions and a different reporting focus.

Emerging players

• WealthOS: UK wealthtech offering a SaaS wealth management infrastructure platform with modular capabilities (client onboarding, portfolio management, reporting) for advisers and wealth managers. Comparable target customer and modular architecture to Graphene, though typically servicing smaller firms.
