The voice layer for every business call.
Heavano Ltd is a UK-based enterprise voice AI company. We build AI phone agents that answer, book, support, qualify, and sell on live calls — in 42 languages, 24/7, at roughly 312ms turn latency — so your business never misses a call again.
Why we built Heavano
Most businesses still lose revenue to the simplest failure: a call that goes unanswered. Voicemail, hold music, and after-hours gaps quietly send customers to competitors. Heavano replaces that gap with an agent that picks up instantly, understands intent, takes real action, and speaks like your brand — in the caller’s own language.
We obsess over the things that make a voice agent feel human: sub-second latency, natural turn-taking, accurate understanding grounded in your knowledge base, and the ability to actually complete tasks rather than just talk about them.
What we believe
Latency is the product
A voice agent only feels human if it answers fast. We engineer the whole stack around a ~312ms turn so conversations never stall.
Every language, natively
Not translation — native speech in 42 languages, with mid-call code-switching so customers are met in the language they trust.
Outcomes, not transcripts
Agents don’t just talk; they book, qualify, collect, and resolve — then sync a clean summary to your systems.
Enterprise trust by default
SOC 2 Type II, ISO 27001, UK & EU GDPR, automatic PCI redaction, and graceful human handoff come standard.
By the numbers
