WealthKernel

What WealthKernel does

WealthKernel is a London-based B2B digital investment infrastructure provider founded in 2015, operating as an API-first platform that supplies the underlying plumbing for fintechs, wealth managers, and established businesses to launch and operate digital investment services. The company's core offering is a modular, RESTful API platform covering the full investment lifecycle, including client onboarding with automated KYC/AML, UK tax wrappers (ISA, GIA, SIPP, JISA), account funding (BACS, CHAPS, open banking, direct debits), asset transfers, licensed custody, trading (both aggregated batch trading and real-time execution), programmatic portfolio management and rebalancing, and direct FCA transaction reporting. Notable technical components include support for fractional ownership from as little as £1, multi-currency trading in GBP/EUR/USD, a sub-broker model with GBP settlement, and an Appointed Representative service that lets firms operate under WealthKernel's regulatory permissions without obtaining their own FCA authorization.

The company is dual-regulated by the UK Financial Conduct Authority (no. 723719) and Spain's CNMV, one of only a handful of API-first providers with both authorizations, and holds ISO 27001:2022 certification with FSCS-protected eligible balances and CASS-compliant client asset handling. WealthKernel monetizes primarily through consumption-based, cost-per-transaction fees invoiced monthly, with commercial terms negotiated per tenant. Its tenant base spans UK and European fintechs and startups such as Wahed (Islamic/ESG investing across 130 countries), Stratiphy, Wealthyhood, Fint, GetGround, Wealth8, and Seapoint, covering use cases from robo-advisory and fractional trading to treasury management. In October 2024 the company expanded into Spain under CNMV authorization, and in April 2026 it was acquired by US-based brokerage infrastructure provider Alpaca, now operating as Alpaca Europe with combined reach across 40+ countries and over 10 million accounts. Prior to the acquisition, WealthKernel had raised approximately $14 million in total funding, including a $7 million Series A+ led by XTX Ventures in January 2022.

Broad incumbents

• Alpaca: US-based API-first brokerage infrastructure provider and parent company of WealthKernel following the April 2026 acquisition. Alpaca powers 10M+ accounts across 40+ countries and offers commission-free US equities trading via API, making it the closest functional peer from a US perspective and the natural counterparty for transatlantic expansion.
• FNZ: Global wealth management platform providing end-to-end infrastructure to banks, insurers, and wealth managers. Comparable as a large-scale B2B investment platform serving established financial institutions, though broader in scope and more enterprise-focused than WealthKernel.
• Avaloq (Oracle Financial Services): Swiss-origin wealth management technology platform now part of Oracle, serving banks and wealth managers with core banking, portfolio management, and regulatory infrastructure. Comparable as an incumbent investment technology platform, especially relevant for European institutional clients.
• Interactive Brokers: Global electronic brokerage providing institutional and retail trading infrastructure, including API access for programmatic trading. Comparable as a regulated, technology-led brokerage serving both retail investors and embedded-finance use cases, though it operates a direct brokerage rather than pure B2B infrastructure model.

Direct peers

• DriveWealth: US-headquartered fractional trading and brokerage infrastructure provider that powers neobrokers and embedded investing apps globally via API. Closely comparable to WealthKernel in business model (B2B API-first investment infrastructure), though focused on US-listed securities and global emerging markets.
• Apex Fintech Solutions: US-based fintech infrastructure provider offering clearing, custody, and a full technology stack to broker-dealers, fintechs, and wealth managers. Comparable as a vertically integrated B2B investment infrastructure provider serving digital-first financial firms.
• Seccl: UK-based embedded investment technology provider offering custody, trading, and API infrastructure to advisers, platforms, and fintechs. Highly comparable to WealthKernel in the UK market with similar B2B API-first architecture and FCA-regulated custody offerings.

Emerging players

• Plaid: US-based financial data connectivity platform expanding into brokerage and investment infrastructure. Comparable as developer-first financial infrastructure, though primarily known for account connectivity rather than trading and custody.
• Bambu: Singapore-headquartered B2B robo-advisory and investment infrastructure provider serving banks, wealth managers, and fintechs globally. Comparable as a white-label investment infrastructure provider with API-based portfolio management and trading capabilities.

Regional players

• Allfunds: European B2B fund distribution and wealthtech platform providing infrastructure for fund processing, custody, and digital wealth services. Comparable as a European-headquartered B2B investment infrastructure provider with regulated operations across multiple jurisdictions.
