iS Prime Founders Reunite to Launch JT Prime
Raj Sitlani, Jonathan Brewer and Jeff Wilkins have launched JT Prime, a new institutional Prime of Prime (PoP) business. The firm is the institutional arm of JT Markets, a retail brokerage established in 2024; it will provide aggregated Tier 1 liquidity and execution services to brokers, funds, family offices and proprietary trading firms, according to a company press release published on 10 November.
The three have built a PoP together before. Sitlani and Brewer held senior e-FX roles at Goldman Sachs before co-founding iS Prime, now iSAM Securities; Wilkins joined them there as head of iS Risk Analytics. At JT Prime, Sitlani is Non-Executive Chairman; Brewer and Wilkins are Partners.

The offering
JT Prime offers access to aggregated Tier 1 bank and non-bank liquidity across FX, precious metals and index CFDs, supported by FIX API connectivity and low-latency execution infrastructure. The founders have spent recent months building the offering on their established bank and non-bank relationships. The firm has a presence across North America, Europe and Asia; it also offers a white-label education platform for institutional clients.
The company describes its model as high-touch and relationship-led, with bespoke liquidity solutions and direct access to senior personnel. Execution is agency-style.
Regulatory and product plans
JT Prime has an application for regulatory approval pending in what it describes as a major Western market; the jurisdiction was not named. It also plans to extend its product range beyond FX and commodities into digital assets, building on its existing capability to accept crypto payments.
Parent JT Markets is a trading name of JT Markets Limited, incorporated in the Republic of Seychelles and regulated by the Financial Services Authority under licence number SDL215.
What the founders said
Sitlani said the team sees “a clear opportunity for a boutique, best-of-breed provider that combines institutional-quality liquidity and technology with a genuinely personalised approach to client relationships.”
Brewer framed the launch as a return to the original PoP model:
With JT Prime, we’re returning to the fundamentals of the Prime of Prime model: providing clients with access to a wide pool of Tier 1 liquidity through a clean, agency-style execution model that aligns our interests with theirs.

He added that the firm will be selective about the clients it works with.
Wilkins said the approach is “consultative and hands-on, helping clients optimise their liquidity arrangements, identify the most suitable liquidity providers and improve the performance of their businesses.”
