On roadmap

Built secure from day one. Audits underway.

We're pre-launch, so we're not going to fake a badge. Today: AES-256 at rest, TLS 1.3 in transit, EU & US data residency, zero-retention mode, and no training on customer audio. SOC 2 Type II is in audit; HIPAA BAA lands with GA.

A PROMISE

We haven't launched yet.
Here's what we commit to when we do.

Avoxx is being built in the open by a small team who've shipped voice infra before. While we're in waitlist, this is what we're committing to — on the record.

01
Built for developers, first.

Typed SDKs, swappable models, inspectable transcripts. Every layer is an API, not a black box.

02
No lock-in. Ever.

BYO keys, exportable transcripts, open SDKs. If you leave, you take everything with you.

03
Waitlist pricing locked for 24 months.

Whatever we launch at, early-access teams keep. No surprise re-pricing at renewal.

04
Direct line to the team.

Shared Slack, weekly build notes, and we answer our own support.
