The confusion is rational
Both products speak. Both mention transcripts. Both demo in a browser. A buyer who is tired of missed calls and a buyer who is tired of weak first-round interviews will type similar words: AI voice, AI phone, AI sales.
The split is who is supposed to talk.
- Fonio: the AI talks to the customer so staff can stay with the work in front of them.
- Kulissa: the human talks to an AI buyer so the real customer is never the first live counterpart.
If your bottleneck is a spa front desk that drops bookings, Fonio is the aisle. If your bottleneck is 200 SDR applications and no comparable scores, Kulissa is the aisle. Many companies will eventually want both. They are not substitutes.
What Fonio is strong at
Public pages emphasise 24/7 coverage, appointment booking, CRM and calendar integrations, and a partner program. Implementation is described as minutes for the assistant itself, longer if you wire systems. That is inbound operations software.
What hiring managers still lack after a phone agent
A phone agent does not rank candidates. It does not turn interview gaps into onboarding. It does not tell a manager who is ready after a playbook change. Those are the seven sales pains we hear in the field, plus the noisy applicant pool. See the funnel on the homepage.
