JLL Arranges First South Florida Office Lease For New York-Based Commercial Lender

JLL has secured a 5,995-square-foot office lease on behalf of Big Think Capital, a New York-based fintech-driven commercial lending platform, at The Onyx Tower, located at 1010 S. Federal Highway in Aventura.

The deal marks the company’s first permanent office location in South Florida as it continues expanding nationally, following a recent expansion of its New York headquarters.

The JLL team representing Big Think Capital in the lease negotiations included Tyler de la Peña, Senior Vice President; Adam Meitus, Associate Vice President. Juan Ruiz, Vice Chairman, and Jack Davidson with Blanca Commercial Real Estate represented the landlord.

Founded in New York, Big Think Capital is a fintech-driven commercial lending platform that provides customized financing solutions to small and medium-sized businesses across the United States. The company specializes in a wide range of capital products including working capital loans, SBA financing, equipment financing, business lines of credit and revenue-based funding, leveraging technology and strategic partnerships to streamline access to capital for growing businesses.

“Aventura continues to attract a growing number of professional services and technology firms seeking access to a highly connected South Florida location” said de la Peña, Senior Vice President at JLL. “With proximity to affluent residential communities, major transportation corridors and a robust mix of retail and dining destinations, Aventura offered an ideal setting for Big Think Capital’s transition from a co-working environment into its first permanent Miami office space – a move that reflects the company’s continued growth and long-term commitment to the South Florida market.”

Located in the Hallandale Beach/Aventura corridor, The Onyx Tower is a 28-story Class A office property offering a hospitality-driven workplace environment with an extensive amenity package. The building features a state-of-the-art fitness center, rooftop lap pool, tenant lounge and event space, on-site café, valet service and wellness-oriented amenities designed to enhance the tenant experience. With modern architecture, expansive views and convenient access to both Miami-Dade and Broward counties, the property has emerged as one of the premier office destinations in the South Florida market. The leased suite was delivered fully furnished, enabling an expedited occupancy timeline for the tenant.

“This expansion represents more than just a new office — it’s another milestone in the evolution of Big Think Capital said David Brown, CEO of Big Think Capital. “South Florida has become an increasingly important hub for innovation, entrepreneurship and business growth, making Aventura a natural fit for our continued expansion. We’re building a high-performance organization centered around growth, innovation and opportunity, and this new office reflects our long-term commitment to investing in top talent, strengthening our national presence and continuing to deliver fast, flexible capital solutions to small businesses across the country.”

According to JLL’s Q1 2026 Miami-Dade Office Report, the Miami office market entered 2026 with steady fundamentals and continued tenant demand, posting positive net absorption and sustained leasing activity across major submarkets. Vacancy remained relatively stable at 16%, while overall direct asking rents climbed more than 7% year-over-year, reflecting ongoing demand for high-quality office space. As premium space tightens in the urban core, tenant activity continues expanding into adjacent submarkets such as Coral Gables, Coconut Grove, Wynwood, and the Airport area, underscoring Miami’s continued evolution as a major business and investment hub.
