The Synthflow alternative
without a $30,000-a-year contract.
Synthflow dropped its self-serve plans: it now works on Enterprise contracts from $30,000 a year. With 008 Agent you start with no fee, paying per minute, and move up a plan when your volume calls for it.
No annual minimum
Start on the Rookie plan, with no monthly fee, at $0.39/min.
Prices in the open
Plans and per-minute prices are published. No lock-in.
Just another extension
The agent registers on your PBX like a desk phone: your numbers and your carrier stay the same.
Scale without limits
Every call spins up its own pod: it scales horizontally and call 1,000 sounds just like the first.

Where Synthflow still wins.
Synthflow has clear strengths for large accounts.
EU data
A Berlin company with an EU data environment.
Contact centers
Integrations with Five9, Genesys, Talkdesk, 3CX and others.
Implementation included
It works with a full implementation service and SLAs.
If your contract is above $30,000 a year and you want it implemented for you, Synthflow may fit. If you want to start now and pay per minute, 008 is the short route.
It plugs into your phone system as it is.
Bring your SIP trunk or your PBX and connect it straight to the pods. No need to change carriers or numbers.
Your trunk, your numbers
Connect your current carrier over SIP.
Works with your PBX
The agent joins as just another extension.
Transfers to your team
Hands the call to a person when needed.
Integrated with your stack
CRM, helpdesk and calendar, no code.
500, 1,000… as many as you need.
Every new call spins up its own pod. No matter how many run at once, none takes resources from another.
It slows down, whispers and even laughs.
It doesn't just understand what you say: it adjusts pace, volume and emotion the way a person would. Ask it to slow down and it does. If you're in a library, it lowers its voice.
Pace on request
Slower for reading out numbers, quicker when you're in a hurry.
Volume and whisper
Lowers its voice when the moment calls for it.
Real emotion
It laughs, empathizes and sounds warm, not robotic.
Matches your tone
It adapts to the way each customer talks.
Sorry, could you say that again more slowly?
Sure. Your order number is… four… seven… two… nine.
«Forty-seven, eighty-one, twenty-two, zero five, N as in Nancy»
008 AgentIDs, orders and phone numbers, right the first time.
It's where almost every voice agent fails: ID numbers, order numbers, phones or emails read out over the phone. Ours captures them, repeats them back to confirm and validates them before saving.
Understands how people dictate
Groups, pauses, «double zero», «N as in Nancy».
Validates before saving
ID check letter, phone format, order length.
Confirms it with you
Repeats the data out loud before moving on.
Emails without typos
Dots, dashes and at signs in the right place.

Not for new customers: its pricing page only offers Enterprise contracts from $30,000 a year.
Nothing fixed: the Rookie plan has no fee and a minute costs $0.39, with voice and LLM included. As your volume grows, Vanguard and Elite lower the minute in exchange for an instance fee, and at high volume Enterprise applies big discounts.
Yes. The agent registers as an extension on your PBX or connects to your SIP trunk, so you change neither carrier nor numbers.
Handing a call to your team is a transfer to another extension, just like with a person.
No. You can change plans or leave whenever you want.
