Flow Traders is a global liquidity provider and market maker founded in 2004 in Amsterdam, the Netherlands. The company specialises in exchange-traded products (ETPs), including equities, fixed income, currencies, and – increasingly – digital assets. Flow Traders listed on Euronext Amsterdam in July 2015, making it one of the few market makers to trade as a public company. It operates from offices in Amsterdam, New York, Singapore, and other financial centres, giving it round-the-clock coverage across global markets.
The firm's core business is proprietary trading – it does not manage outside capital in the traditional asset-management sense, so a conventional AUM figure is not publicly disclosed. Instead, Flow Traders reports net trading income, which has ranged from roughly €200 million to over €700 million annually depending on market volatility. The company entered crypto markets as an early ETP market maker, and by 2021–2022 had established itself as one of the most active liquidity providers for Bitcoin and Ethereum ETPs listed on European exchanges. Its strategic corporate investments – the portfolio of roughly 15 companies referenced in its filings – sit alongside this trading business and focus on market infrastructure, data, and digital-asset technology.
Notable investments
- Bitstamp – Flow Traders has had a documented commercial and strategic relationship with Bitstamp, one of the oldest regulated crypto exchanges, supporting liquidity on the platform.
- Digital-asset infrastructure firms – The company has participated in funding rounds for companies building prime brokerage, custody, and settlement infrastructure for institutional crypto markets. Specific deal names and sizes beyond Bitstamp are not fully disclosed in public filings as of early 2026.
- Crypto ETP issuers – Flow Traders acts as authorised participant and market maker for a wide range of Bitcoin and Ethereum ETPs listed in Europe and, following the January 2024 SEC approval, for US spot Bitcoin ETFs. This operational role often accompanies equity stakes or commercial agreements with issuers.
Public information about the full breakdown of Flow Traders' 15 portfolio companies is limited. The firm does not publish a dedicated venture portfolio page, and deal-by-deal disclosures are sparse in its annual reports.
Team
Flow Traders was co-founded by Jan van Kuijk and Roger Hendriks, who built the firm from a small Amsterdam trading desk into a multinational market-making operation. Day-to-day executive leadership has been held by a management board that reports to a supervisory board, as required under Dutch corporate governance rules for listed companies. Detailed biographical information on current managing directors is available in the company's investor relations section. The firm employs several hundred traders, technologists, and quantitative researchers globally.
Recent activity
The 18 months through early 2026 were strategically significant for Flow Traders in digital assets. The launch of US spot Bitcoin ETFs in January 2024 – products Flow Traders was positioned to support as an authorised participant – materially expanded its crypto trading volumes. The firm publicly welcomed the regulatory development and cited it as a validation of the ETP market-making model it had already built in Europe. Flow Traders also continued to engage with regulators on the Markets in Crypto-Assets (MiCA) framework, which reshapes how crypto asset services operate across the European Union from 2024 onward.
On the corporate side, the company signalled continued investment in trading technology and headcount in Asia-Pacific, reflecting the growth of crypto and ETP markets in that region. No major acquisitions or divestments were publicly announced during this period, though the firm is known to quietly take minority stakes in companies that support its core liquidity-provision business.
Flow Traders occupies an unusual position in the crypto ecosystem: it is neither a pure venture investor nor a retail-facing exchange, but a critical piece of institutional market infrastructure. Its financial health is tied to volatility – calm markets compress spreads and reduce trading income – which creates cyclicality that investors in the public stock must manage. For crypto projects and ETP issuers seeking a well-capitalised, regulated market-making partner with direct access to European and US exchange infrastructure, Flow Traders remains one of a small number of genuinely institutional-grade options. Further detail on its corporate investments can be found via its official website and annual reports filed with Euronext.
