Austin-Based Tech Firm Telnyx Debuts on National Software Rankings, Signaling Broader Texas Surge

The Austin-based telecom/AI company debuts at No. 6 on Brex Benchmark's Spring 2026 rankings.

Under Governor Greg Abbott's leadership, Texas has spent the last several years making the case that you do not need a California zip code to build a world-class tech company. The latest evidence comes from Austin, where Telnyx, a telecommunications and AI infrastructure firm, has been named the #6 fastest-growing software vendor in the country on the Brex Benchmark's Spring 2026 report.

The Brex Benchmark is a closely watched barometer of the “top software and AI vendors by dollar spend.” Unlike surveys or analyst projections, it draws from actual spending data across more than 35,000 companies. Each quarter, Brex analysts rank vendors by “momentum, scaling velocity, and dollar growth acceleration.”

Governor Abbott has been deliberate about making Texas the country's most competitive state for tech investment, launching the JETI incentive program to attract large-scale capital, championing the Texas CHIPS Act to solidify the state's dominance in semiconductor manufacturing, and securing a $250 million grant to Samsung's Austin facility as part of a $4.73 billion investment deal.

Tech companies have listened. Tesla officially moved its global headquarters from California to Texas in 2021, building its gigafactory and company headquarters just outside the city. Apple has expanded its Austin campus to more than 6,000 employees, one of its largest footprints outside Cupertino. Dell Technologies has anchored the region for decades.

"Austin is becoming the real home of serious tech infrastructure, and Telnyx is proof,” co-founder and CEO of Telnyx, David Casem, told us exclusively. “This recognition reflects what our customers already know, that owning the full stack, from the network layer to AI inference, is what makes real-time intelligence actually work.”

Founded in 2009, Telnyx has quietly built what it calls a “full-stack carrier network” and AI inference. The platform allows businesses to design and deploy AI-powered voice agents and scale real-time communications without the typical tradeoffs in latency or reliability.

Casem told Texas Politics that the company has grown its workforce by more than 20 percent year over year, with Austin as its primary hub, adding to a job market that is already one of the strongest in the country for tech employment.

Telnyx's trajectory fits that same pattern of high-growth companies betting on Texas over Silicon Valley.
