Flark works on the services behind your voice AI, not on your agents. You keep your products and your stack.

Better terms

More competitive rates and purchasing conditions for the services already powering your voice AI.

Clear cost control

Provider usage, agent costs and client-level attribution in one clear picture, so you always know where the money goes.

Simpler operations

Manage consumption across providers in one place as your usage grows, without rebuilding the agents you run.

Also included

  • One invoice in euros for voice, LLM and telephony.
  • Vetted providers, assessed for latency, Castilian Spanish voice quality and GDPR.
  • Freedom to switch providers and models without rebuilding your agents.
  • Spanish telephony: +34 numbers, SIP and call recording that meet local rules.
  • Escalations with weight when something breaks with a provider.
  • Benchmarks on which mix of voice, model and telephony works best per use case.

Optional · Takes a minute

Check your current cost per minute

Already in production? Add your total spend and minutes. Planning a project? Estimate the minutes you will need. Nothing here is required to book a call.

Your stack

—current spend a year

This is your baseline, not a savings estimate. We compare it with the terms available for your setup in the call.

Improve my Voice AI spend

Start with what you already use.

A straightforward conversation first. Any change to purchasing, accounts or integrations comes later, with the economics and requirements clear.

  1. Tell us your providers and spend

    An overview of your infrastructure, current costs and terms. No credentials needed.

  2. We review terms and usage

    We look at where better conditions, clearer allocation or simpler usage control would help.

  3. You decide what to change

    See the proposed terms, requirements and trade-offs before anything touches production.

Twilio and ElevenLabs first

Most voice agents run on these two providers, so that is where we start.

Twilio

Telephony for your agents.

  • Voice minutes
  • +34 numbers
  • SIP trunking
  • Call recording
ElevenLabs

Voice and agents, including the LLM they use inside ElevenLabs.

  • Conversational AI minutes
  • Text-to-speech
  • Castilian Spanish voices
  • Concurrency

Before you book

What changes in my stack?

Nothing to start. The first conversation needs no migration and no credentials: just an overview of your providers, spend and current terms. Your agents and products stay as they are, and any later change is agreed with you before it happens.

What would I be committing to?

Nothing by booking. If we find better terms for your setup, you see the conditions, requirements and trade-offs first and decide whether to adopt them. If you join and later want to leave, we help you move your accounts and numbers back.

How do you charge?

The conversation and the review are free. If you adopt terms through Flark, our fee is agreed with you upfront, and every figure we show you is already net of it.

What data do you need?

Your providers, approximate monthly spend and minutes, and the terms you have today. Never API keys, credentials, call recordings or your clients’ data. See the privacy notice.

Is Flark another voice-agent builder?

No. Flark focuses on the services behind voice AI: supplier terms, cost visibility and usage control. It is in early access while we confirm supplier terms with our first users.
