lemon.markets
lemon.markets was founded in Berlin to solve a structural bottleneck in European financial services: the cost, complexity, and duration of building a regulated brokerage product from scratch. Rather than operating a consumer-facing app, the company provides a white-label API that handles user onboarding, identification, order management, asset custody, and regulatory administration — allowing banks, EMIs, and software firms to add investment capabilities to their existing interfaces without acquiring a securities license or building a full brokerage stack internally. The platform provides coverage across stocks, ETFs, and funds through its own securities accounts and custody, while also accommodating partners that prefer to use their own cash-account arrangements. Positions confirmed through its developer documentation and public partner communications include standardized order-routing logic and automated tax-reporting outputs, making the API suitable for regulated entities that must issue client statements across multiple European tax jurisdictions. The firm emphasizes modularity — partners can adopt the full end-to-end value chain or plug specific components into their existing license framework. Current headcount and total capital deployed are not publicly disclosed. The firm's contact page indicates a team with deep brokerage and regulatory expertise, and its website states that it partners with established financial institutions, though no specific bank or wealth-manager names are published. lemon.markets does not list a separate philanthropic foundation or adjacent operating vehicle, and its public materials do not reference co-investment clubs or multi-family-office structures. lemon.markets differs from most B2C fintechs and from conventional B2B middleware providers in one key respect: it acts as a principal-facing counterparty that assumes the full regulatory perimeter — securities accounts, custody, tax reporting — and exposes it through a developer-first API. This means a neobank, a fleet-management software company, or a payroll provider can launch an investment feature without ever holding a BaFin securities license, shifting the structural burden of European regulatory fragmentation onto lemon.markets' own compliance and operational architecture.

Frequently asked questions
How does lemon.markets generate revenue?
lemon.markets functions as a B2B infrastructure provider rather than a consumer brokerage. Revenue is generated through usage-based or subscription fees paid by institutional partners — banks, EMIs, and software companies — that integrate the API. The firm does not publicly disclose its pricing model, but comparable brokerage-as-a-service platforms typically charge a combination of platform fees and per-trade transaction economics.
What is the regulatory structure behind the API?
lemon.markets provides its partners with securities accounts, custody, and order management under its own regulatory umbrella, meaning the end-client's assets sit with lemon.markets' custody infrastructure rather than with the partner's balance sheet. The firm handles BaFin compliance, tax reporting, and client-asset administration, which allows a partner without an in-house securities license to offer investment products. Partners that hold their own licenses can use the API in a modular configuration, retaining their own cash accounts while relying on lemon.markets for securities account operations.
Does lemon.markets operate a consumer-facing app?
No. lemon.markets does not maintain a consumer-facing brokerage app or direct retail client relationship. The firm operates exclusively as an infrastructure layer that other companies — banks, wealth managers, vertical SaaS platforms — embed into their own customer experiences. End-users invest through their existing bank or software interface without knowing lemon.markets operates the underlying brokerage rails.
Which asset classes can partners offer through the lemon.markets API?
Public documentation indicates the API supports stocks, ETFs, and funds. Partners gain access to a multi-venue order management system that routes trades across European exchanges. The firm does not currently list fixed-income products, derivatives, or private-market instruments among its supported asset classes, though the modular architecture could in principle accommodate additional instruments.
What makes lemon.markets different from a standard introducing broker or B2B custodian?
lemon.markets combines custody, securities account operations, order execution, compliance administration, and tax reporting into a single RESTful API that partners test in a sandbox environment before launching. A standard custodial partner typically requires months of bilateral legal negotiation and custom integration. lemon.markets' structure pre-packages the full regulatory and operational chain into developer documentation and self-service dashboards, shortening integration timelines from months to weeks.
Is lemon.markets a single family office or a wealth manager?
No. lemon.markets is an API-first brokerage infrastructure company. It is not a family office, multi-family office, or direct wealth manager. The Altss profile classifies it as an asset manager in the broadest sense — it manages the custody and execution of client assets — but its business model is fundamentally a technology infrastructure play serving institutional partners.
How does lemon.markets handle client money and asset segregation?
The firm states it handles the safe-keeping and servicing of all customers' assets and provides both cash and securities accounts, implying standard asset segregation practices as required under German regulatory rules. Precise custody-chain arrangements (for example, the use of a global custodian or direct central securities depository membership) are not specified in public documentation.
