After enough months of debugging silent webhook failures and integration drift on Vapi+n8n builds, we built our own voice stack from scratch. Tighter latency, no middleware to maintain, complex new agents spun up in 48-72h. We're not selling tooling to other builders — we are looking for agencies who want to stop being the technical team on voice projects. You bring clients, we handle the entire build + ops. Pay-per-minute or white-label. If voice AI is part of your offering and you're tired of patching workflows, drop a vertical you're working on (HVAC, dental, med spa, etc.) below and I'll reply in-thread or feel free to DM.
