Last fall, the Dallas-based TXSE Group launched its Oculon Intelligence division as a security-first, AI-native market intelligence platform for U.S. Securities and Exchange Commission compliance and data analytics. Now Oculon has a new heavy hitter on its team: Chief Technology Officer Dinand Vanvelzen.

In a January LinkedIn post, TXSE Group Founder and CEO James H. Lee said Dinand “brings over two decades of experience building and leading mission-critical technology organizations, including key roles at Citadel and TradeStation.”

“His technical expertise and understanding of how to scale complex, high-performance systems,” Lee added, “make him a critical addition to our team and reflects our belief that being able to write and control our own technology will be a major advantage that we have.”

Vanvelzen joins Oculon President Ovi Montemayor, former managing director of market and execution services at Charles Schwab, and Oculon SVP David Saltiel, former acting director of the SEC’s Division of Trading and Markets, as part of the division’s senior leadership team.

Dallas-based Oculon operates independently from TXSE Group’s Texas Stock Exchange, which is ramping up its presence on “Y’all Street” by launching training on its trading engine in Q1 2026, with listings of exchange-traded products (ETPs) and corporate issues expected to go live later this year.

Oculon is meeting ‘a need in the marketplace’

As Glenn Hunter wrote in Dallas Innovates in November, Oculon’s integrated suite of software products “wasn’t the idea of the TXSE Group,” according to TXSE strategic advisor Jeb Hensarling’s remarks at the 2025 Venture Dallas conference.

Instead, TXSE was “approached by major market players who said, ‘We know you have the capability to do this. There is a need in the marketplace, and we are turning to you to do it,'” Hensarling said.

Developed in consultation with leading financial institutions, Oculon Intelligence’s execution analytics, regulatory reporting, and multi-product cross-market surveillance tools are designed to boost efficiencies, protect investors, and enhance market quality.

Platform is enhanced with multiple LLMs

Oculon Intelligence is a security-first, AI-native software-as-a-service (SaaS) market intelligence platform that combines regulatory reporting insights, execution analytics, and market surveillance across equities and options, TXSE Group said.

Built with data protection and security at its core, the platform is Initially focused on equities and options. Oculon’s key capabilities include high-frequency data ingestion and advanced analytics to enable firms to continually improve their performance and fine-tune their execution strategies.

Leading these capabilities, TXSE Group said, are flexible, market structure-specific agentic AI tools enhanced with multiple large language models applied to highly regulated institutions.

Turning a shift in SEC rules into ‘a competitive edge’

]Oculon’s launch timed to address a big shift in federal regulation: the SEC’s overhaul of Rule 605, which governs how brokers and market centers must report the quality of their trade executions. The first update to the rule in over 20 years, the overhaul expanded the definition of a “covered order” to include fractional shares and odd lots. That rule change exponentially increased the amount of data that firms are required to track and report, creating what some have called a “data explosion.”

To help tamp down that explosion, Oculon’s compliance suite aims to address SEC requirements for Rule 605 execution quality reporting and Rule 606 order routing disclosure, by helping the industry meet these new standards “with fast, trustworthy AI-powered tools,” TXSE Group said.

“Oculon Intelligence gives market participants the infrastructure they need to turn compliance into a competitive edge,” Montemayor, Oculon’s president, said during the division’s September launch. “Our goal is to strengthen trust, transparency, and fairness across U.S. capital markets while helping firms operate with greater precision and confidence.”

Saltiel, the team’s SVP, noted that the competitive and regulatory environment “is evolving quickly.”

“Firms need tools that provide flexibility and the highest level of data protection,” Saltiel said in September. “Oculon Intelligence is built to help firms adapt to this future and improve market efficiency.”

During his tenure as former acting director of the SEC’s Division of Trading and Markets, Saltiel helped oversee the launch of the updated SEC rules Oculon is being built to automate.

Vanvelzen to help drive Oculon’s agentic AI platform

Vanvelzen’s addition as CTO gives Oculon a key architect for its agentic AI platform. Backed by his experience at Citadel and TradeStation—and a career spanning the Netherlands, fintech systems, and senior engineering in U.S. financial technology—Vanvelzen will be working at the cross-section of high-frequency markets, regulation, and AI. 

The capital markets technologist and real‑time systems architect began his career in the Netherlands, where he worked at Pie Medical Imaging, university research labs, and Philips Healthcare, focusing on 3D rendering, visualization, and large‑scale medical software architecture.

After moving into embedded and enterprise systems at TOPIC Embedded Systems, he transitioned into capital markets as a software architect and project manager at Citadel, leading the company’s Market Connectivity group across multiple countries and time zones, and replacing inflexible legacy software with a flexible, real‑time system for connecting to global markets and translating protocols such as FIX.

Now, in his new role, Vanvelzen is tasked with turning Oculon’s AI platform into real‑time “eyes and ears” for modern markets—as the trading launch of the Texas Stock Exchange looms in the months to come.
