PropHub Secures Strategic Venture Round to Revolutionize Brokerage Composability

PropHub has secured a strategic venture round led by Merchant Seven to scale its modular infrastructure for brokerages and proprietary trading firms. The investment targets the growing demand for "composable" trading stacks, allowing operators to launch platforms across traditional and on-chain markets without maintaining a fragmented patchwork of third-party vendors.

What was announced

The strategic venture round, led by Merchant Seven (M7) with participation from a group of private investors, provides capital to expand PropHub’s product suite and accelerate international adoption beyond its current operations in Latin America. The company’s core offering is a single, modular stack exposed through consolidated REST and WebSocket APIs, designed to replace the disparate systems typically required for back-office operations, risk tooling, and payment processing.

PropHub’s ecosystem is organized into three distinct verticals. The brokerage vertical provides a white-label platform including CRM, dealing-desk risk management, and payment integrations for deposits and withdrawals. For the proprietary trading sector, the firm offers an end-to-end operating system featuring trader onboarding, KYC, challenge engines, and automated profit splits. This vertical is delivered through specific modules including Prop OS, RiskOps, PropOversight, and FlowManager. The third vertical focuses on crypto, providing white-label decentralized exchange (DEX) infrastructure on Hyperliquid and other protocols, supporting perpetuals, spot trading, and tokenized real-world assets (RWAs) with Web2-grade onboarding via embedded self-custodial wallets.

As part of the investment, PropHub joins the Harbor program, which grants the firm access to M7’s forward-deployed engineers (FDEs). These senior operators embed directly within the company to assist with technical scaling and go-to-market functions. This model was specifically designed to address the difficulty younger companies face when hiring category experts in the specialized trading technology sector.

The companies involved

PropHub is a specialist technology provider serving brokerages, proprietary trading firms, and crypto platforms. The company was founded by Gabriel Kassouf, who serves as CEO, alongside CPO Felipe Vella and CTO Rafael Viveiros. The leadership team brings over a decade of individual experience in the trading and investment space, having previously managed day-to-day trading operations. This first-hand experience informed the development of their "one-shot" stack, which aims to reduce the capital and time expenditures usually associated with stitching together a dozen different vendors to serve retail or professional clients.

Merchant Seven (M7) is a venture firm led by Founder and Managing Partner Pierce Crosby. The firm operates the Harbor program, a model that provides portfolio companies with both capital and embedded engineering talent. M7 developed this approach in response to a growing constraint in the fintech sector: the increasing difficulty of hiring world-class talent in trading technology. By deploying senior operators to work alongside founders, M7 attempts to bridge the gap between early-stage development and the technical requirements of established market participants.

What this means

The rise of "prop-firm-as-a-service" and modular brokerage stacks signals a significant shift in how trading platforms are built and maintained. By lowering the technical barrier to entry, infrastructure providers are placing immense pressure on legacy turnkey systems that offer rigid, non-modular architectures. The inclusion of on-chain settlement and RWA tokenization within the same stack as traditional brokerage tools suggests that the wall between Web2 and Web3 trading is rapidly thinning. However, the reliance on embedded engineering programs like Harbor highlights a critical industry bottleneck: capital is no longer the primary differentiator in fintech; access to specialized, high-level technical talent is the new currency of the sector.
