What WEBB Traders does
WEBB Traders B.V. is a global proprietary trading company and market maker founded in 2009 in Amsterdam by Marco van den Berg and Thijs Booij. The firm uses its own capital to provide liquidity on major EU and US stock and derivatives exchanges, acting as a market maker in over one million financial instruments across cash equity, derivatives, and FX. It specializes in single-stock options market making for European and US mid and large cap equities, employing approximately 70 staff representing 25+ nationalities across offices in Amsterdam, Paris, and London, and is regulated by Dutch supervisors AFM and DNB.
The firm operates a low-latency electronic trading platform built on C++, Python, and PostgreSQL, with proprietary algorithmic trading systems designed to capture bid-ask spreads and arbitrage opportunities while internalizing hedging within its own book. WEBB Traders does not sell a software product; its offering is the trading and market making service itself, executed via direct exchange memberships and a network of interdealer brokers. Revenue is generated entirely from trading P&L (spread capture and arbitrage) rather than fees paid by external customers, and the firm is privately held.
In February 2026, Marex Group plc announced an agreement to acquire WEBB Traders, with closing expected in Q2 or Q3 2026 subject to regulatory approval. Upon close, WEBB's technology-led team of market makers, quants, and developers, along with its European equity derivatives market making capability, will be integrated into Marex's broader Equity Linked Structured Products platform.
