Brex just named Telnyx the #6 fastest-growing software vendor in its Spring 2026 benchmark. That puts us alongside some of the most important AI infrastructure companies in the world: fal, OpenRouter, Runpod, Modal, ClickHouse, Vercel, Supabase, ElevenLabs, Replit, Perplexity, and others. The driver is clear: Voice AI is moving from demo to production. And production Voice AI does not work on a Frankenstack. When developers stitch together telecom, STT, LLMs, TTS, orchestration, and compliance across half a dozen vendors, the product breaks in predictable ways: Latency compounds. Margins disappear. Reliability gets worse. Debugging becomes impossible. Compliance gets pushed onto the builder. Real-time AI agents need a different architecture. They need telecom, edge infrastructure, inference, identity, and agent primitives in one integrated stack. That is what we are building at Telnyx. Today, we are taking the next step: 𝗧𝗲𝗹𝗻𝘆𝘅 𝗶𝘀 𝗼𝗳𝗳𝗶𝗰𝗶𝗮𝗹𝗹𝘆 𝗶𝗻 𝘁𝗵𝗲 𝘀𝘁𝗮𝗻𝗱-𝗮𝗹𝗼𝗻𝗲 𝗶𝗻𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗴𝗮𝗺𝗲. We are running frontier intelligence on B300 infrastructure and pricing tokens the way they should be priced: aggressively, transparently, and for scale. The intelligence layer is becoming a commodity. Developers should not get taxed by wrappers just to build production AI applications. And this is only the beginning. Over the coming months, we will be shipping a wave of purpose-built AI agent infrastructure. The Frankenstack is dead. Build real-time AI agents on Telnyx.

JUST IN: Brex dropped its Spring 2026 Benchmark. The #1 and #2 fastest-growing software vendors are both model routers. That tells you everything about where AI is headed. Brex tracks real corporate card and bill pay spend across 35,000+ companies. - fal.ai is #1. - OpenRouter is #2. Both are routing layers. They sit between developers and the foundation models, letting teams swap providers weekly to optimize cost and performance. The companies building on AI have decided the model layer is a commodity. The orchestration layer is the product. Brex says fal.ai customers are 10-19x more likely than average to also buy directly from foundation model labs. They're using the router AND going direct simultaneously. The aggregation layer is winning without displacing the labs underneath it. If you work in payments, that topology should look very familiar. Other things that jumped out: ~80% of this list are AI companies. The ones that aren't (like PlanetScale at #25) are growing because they serve AI companies. Lovable (#14) went from zero to matching Replit and Framer on spend share in 14 months. Fastest climb in the vibe coding category. Heavy Lovable users are 5x more likely to also use Wispr Flow and Gamma. People who stopped writing code stopped typing everything else too. The software market is reorganizing around whoever sits closest to where work starts. For AI teams, that's the routing layer. For builders, it's where the first line of code gets written. The vendors winning biggest got there first. They're pulling away. Source: Brex Benchmark, Spring 2026
