No business should ever miss a call — or lose a sale to a busy line.
Every ringing phone is a customer trying to give you money, book a table, or get an answer. Fonivo gives every business a voice agent that picks up instantly and actually gets the work done — in Greek and English, around the clock.
Missed calls are missed revenue. We got tired of watching it happen.
Every call that goes unanswered, hits a busy line, or drops into voicemail is a customer who came ready to buy — and walked away. For most small and mid-sized businesses that's not a rounding error; it's a meaningful slice of the week's revenue lost after hours, during the rush, or while the one person who answers the phone is already on another call.
The tools meant to fix this never did. IVR phone trees push callers through menus nobody wants. Voicemail is a graveyard. Call centers are expensive, slow to staff, and rarely know your business. People hang up, and you never even know they called.
Two things finally changed: voice AI got good enough to hold a real conversation, and it can now take real action inside the software you already run — book the appointment, place the order, check the stock, log the call. That combination is Fonivo. We built it in Greece, Greek-first, for Greek and international businesses alike — because great service in your own language shouldn't be a premium feature.
The principles we build on.
A short list we actually hold ourselves to — not a poster on the wall.
Real outcomes, not demos
A voice agent that only talks is a toy. Ours completes the task — the booking, the order, the update — inside your systems, on the call. We measure success by work done, not words spoken.
Speak human — and Greek
Callers shouldn't adapt to a machine; the machine adapts to them. Natural conversation, in Greek or English, switching mid-sentence when the caller does. Greek is a first-class language here, not an afterthought.
Trust & transparency
Every call is transcribed, every action logged, every outcome reported back to you. Data is processed in the EU. You always know what your agent said and did — no black boxes.
Own what's ours, partner for the rest
We self-host the parts that are our craft and pick best-in-class partners for the rest — Twilio for telephony, ElevenLabs for voice. No reinventing solved problems, no lock-in we'd resent ourselves.
An engineering studio in Athens.
Fonivo is built and run by Negletek, a small engineering studio based in Athens, Greece. We're product engineers who like hard problems and shipping software that earns its keep — not slideware.
Our stack philosophy is simple: self-host what's genuinely our job — the orchestration, the connectors, the call logic, the data — so we control quality, cost, and your privacy. For the deep specialist layers, we stand on the best in the world: Twilio carries the telephony, ElevenLabs gives the agent its voice. The result is a product that's ours end to end where it matters, and rock-solid everywhere else.
