Round Backed by Merchant Seven and Private Investor Group
SÃO PAULO, Brazil, Nov. 2, 2026 — PropHub (“PropHub”), a specialist technology provider to brokerages, proprietary trading firms, and crypto platforms, today announced a strategic venture round led by Merchant Seven (“M7”) and a group of private investors. Financing will fund growing PropHub’s product suite, advancing its go-to-market functions, and accelerate international adoption.
“Composability is where the trading industry is heading,” said Gabriel Kassouf, CEO of PropHub. “The next generation of platform builders will assemble their businesses from best-in-class components, across both traditional and on-chain markets. We want PropHub to be the layer that makes that next frontier possible.”
Launching a brokerage, prop firm, or trading platform has traditionally meant assembling front ends, dashboards, CRM, back office, risk tooling, payments, and reporting from a patchwork of providers, then maintaining every integration in between. PropHub replaces that patchwork with a single modular stack of products and features. Operators can start on a single toolset, or commission a fully customized turnkey build, and every product is exposed through consolidated REST and WebSocket APIs.
PropHub’s founders, Gabriel Kassouf, Felipe Vella, CPO, and Rafael Viveiros, CTO, have worked in the trading and investing space for over a decade each, bringing first-hand experience running trading operations day to day. The experience helped them craft a product suite that operators can use on day one.
“We spent years on the operator side of the business, and we know how much time and capital goes into technology that should simply work,” added Kassouf. “Brokers, props, and exchanges shouldn’t have to stitch together a dozen vendors to serve their clients. PropHub is the one-shot composable stack they can launch within days, and can grow into for years to come.”
Through Harbor, PropHub gains access to capital alongside M7’s forward-deployed engineers (FDEs); senior operators who embed directly inside portfolio companies. The model was built by M7 due to the growing constraint in the sector; exceptional category experts in trading technology are increasingly difficult to hire, particularly for younger companies competing with established a foothold.
“It has never been harder to hire world-class talent in trading technology, and that gap holds back too many great young companies,” said Pierce Crosby, Founder and Managing Partner at Merchant Seven. “PropHub’s founders bring rare operator experience and a comprehensive product across brokerage, prop trading, and crypto markets.”
PropHub has built an ecosystem of three core verticals, each available as a white-label platform or a custom turnkey build:
- Brokers: A full brokerage under the operator’s own brand, including trading platform deployment, CRM and back office, dealing-desk risk management, and payments integration for deposits and withdrawals.
- Prop firms: An end-to-end operating system for proprietary trading firms, covering trader onboarding and KYC, a challenge engine, automated payouts and profit splits, affiliate attribution, business intelligence, fraud detection and order-flow hedging, delivered through modules including Prop OS, RiskOps, PropOversight and FlowManager.
- Crypto: White-label decentralized exchange infrastructure on Hyperliquid and other exchanges, spanning perpetuals, spot, tokenized real-world assets (RWAs) and prediction markets, with Web2-grade onboarding through embedded self-custodial wallets, on-chain settlement and a protocol-native revenue layer for operators.
Over the course of the Harbor program, PropHub will expand its product suite across all three verticals, build a repeatable go-to-market engine, establish channel and distribution partnerships, and enter new international markets beyond Latin America.
