Nexona Labs Verified Company

About a year ago, I was running a small call center focused on sales and lead generation for businesses in the US. At the time, AI voice agents were becoming increasingly popular, and competitors were using platforms like VAPI to automate calls. The problem was pricing. At roughly $0.10/minute and similar rates across many providers, the economics simply did not work for a small call center like ours. I approached Nexona Labs with one main question: how can we significantly reduce the cost of running AI voice calls? What impressed me immediately was that they did not simply tell me to accept the industry pricing or jump straight into development. They first researched the voice-agent market, explained how the underlying STT → LLM → TTS architecture worked, and identified the major problems with the conventional approach: high per-minute costs, high latency caused by multiple external API calls, and data passing through multiple third-party systems. Their proposed solution was to run an integrated voice AI pipeline on dedicated GPU infrastructure. The technically difficult part turned out not to be the AI itself, but building the entire telephony system around it: SIP integration, campaign management, lead handling, concurrency, call states, retries, callbacks, dispositions, and the orchestration required to run hundreds of concurrent calls efficiently. Within about one month, I had a working voice-agent prototype. In roughly three months, we had the core MVP, and within six months, I had a fully working platform that I could use for my business. The results were significant. For around 1,000 calls, our operating cost went from approximately $200–300/day using VAPI to around $10.7–11.5/day with our system, while response latency dropped from roughly 3 seconds to around 600–800 ms. We also saw successful leads improve from roughly 5 to 15–20 per 1,000 calls while substantially reducing manual work. What I especially appreciate about Nexona is their communication and technical judgment. They provide updates proactively, involve me whenever product decisions require my input, and don't blindly implement instructions. They explain the trade-offs and suggest better approaches when they see one. Another thing I appreciated was that Nexona gave me the option to retain ownership of the source code. This was important to me because it meant I was not dependent on the agency to maintain control of the product or locked into a proprietary system. I had the flexibility and ownership needed to treat the platform as a long-term business asset. After seeing the potential of the platform, I decided to turn it into a multi-tenant service and offer it to other businesses as Valyrian Voice. Nexona is now not just a development agency for me, but our long-term technical partner. Even after launch, when I raised concerns about how tenant lead data was being stored, they worked on the issue and implemented end-to-end encryption to significantly improve data protection. For me, the biggest reason I would recommend Nexona Labs is that they don't just build what you ask for—they take ownership of the problem, think through the technical solution with you, and genuinely care about building something that works in the real world.
