Synthflow AI is a no-code DIY platform for building AI voice agents, with plans starting at $29/month (50 minutes) and scaling to $450–$1,400/month for higher volumes, plus enterprise contracts from $30,000/year. Agents by AIQ is a done-for-you alternative: AIQ Labs designs, builds, connects, and runs your voice and phone agents for you, integrated with the tools your business already uses. Choose Synthflow if you want hands-on control of the builder; choose Agents by AIQ if you want the agent built and operated for you.
Bottom line: These are different purchase models, not direct feature rivals: Synthflow wins for teams that want to build and manage voice agents themselves with transparent per-minute pricing, while Agents by AIQ wins for owner-operators who want a finished, operated agent without touching a builder.
TL;DR
- Synthflow AI is a no-code voice agent platform: you build agents yourself in a visual Flow Designer, with an AI assistant (Aurora) that can generate agents from a description.
- Synthflow's published plans run $29/mo (Starter, 50 minutes), $450/mo (Pro, 2,000 minutes), $900/mo (Growth, 4,000 minutes), and $1,400/mo (Agency, 6,000 minutes, white-label), with enterprise contracts from $30,000/year.
- Third-party reviews report Synthflow's real all-in per-minute cost lands around $0.15–$0.37 once LLM and telephony are added, and G2 reviewers most often complain about cost.
- Agents by AIQ is a done-for-you service: AIQ Labs designs, builds, connects, and runs AI agents — including AI receptionists answering calls on a real phone number — for small and mid-size businesses.
- Agents by AIQ is month-to-month with no long contract, and the client owns everything built.
- Synthflow holds a 4.5/5 rating on G2 across 1,000+ reviews, with praise for ease of use and voice quality and criticism for cost, customization ceilings, and IVR-like behavior off script.
- If you have time and a technically comfortable person, Synthflow's DIY route works; if you want the agent built and operated for you, book a scoping call with Agents by AIQ.

Synthflow AI
synthflow.ai ↗Synthflow AI is a no-code platform for building AI voice agents that handle inbound and outbound phone calls. Launched in 2023 and backed by a $20 million Series A, it centers on a drag-and-drop Flow Designer where non-technical users assemble call flows, plus an AI assistant called Aurora that can generate an agent from a plain-language description. The platform ships prebuilt templates for service businesses (HVAC, dental, legal, real estate), supports 30+ languages with multilingual voice cloning, and runs on its own in-house telephony network with sub-100 ms latency and a 99.99% uptime target. It integrates with 200+ tools including CRMs, scheduling apps, and CCaaS stacks (Cisco, Avaya, Genesys, RingCentral), supports SIP trunking and bring-your-own-carrier, and holds SOC 2, HIPAA, GDPR, and ISO 27001 certifications. It holds a 4.5/5 G2 rating across 1,000+ reviews and powers 65M+ voice calls per month in 30+ countries.
| Plan | Price | What you get |
|---|---|---|
| Starter | $29/mo | 50 minutes included, 5 concurrent calls, unlimited assistants, API & integrations, community support |
| Pro | $450/mo | 2,000 minutes included, 25 concurrent calls, 8,000 custom workflows, workflow builder, ticket support |
| Growth | $900/mo | 4,000 minutes included, 50 concurrent calls, 42,000 custom workflows, 25 subaccounts |
| Agency | $1400/mo | 6,000 minutes included, 80 concurrent calls, 100,000 custom workflows, unlimited subaccounts, white-label |
| Enterprise | $30000/yr | Custom volume, 200+ concurrent calls, custom integrations, guaranteed uptime, enterprise support |
Pros
- Genuinely fast no-code setup — G2 reviewers report going live in as little as a day
- Large integration library (200+ tools) that connects with most CRMs
- Natural-sounding voices, largely thanks to ElevenLabs under the hood
- Strong white-label and agency reseller tooling with subaccounts
- Enterprise-grade compliance (SOC 2, HIPAA, GDPR, ISO 27001) out of the box
- Transparent per-minute pricing with no charges for failed calls
Cons
- Cost is the most common G2 complaint; add-ons (extra concurrency ~$20/mo each, HIPAA BAA ~30% surcharge, white-label ~$2,000/mo) push real bills above the headline plan price
- Real all-in per-minute rate lands around $0.15–$0.37 once LLM and telephony are included, per independent reviews
- Hits a ceiling on complex customization; a real learning curve beyond simple flows
- Reviewers say the agent can sound like a polished IVR once a caller goes off script
- Outbound dialer and campaign tools lag behind dedicated outbound platforms
Agents by AIQ
agentsbyaiq.com ↗Agents by AIQ is the agent-focused arm of AIQ Labs, offering done-for-you AI agents for small and mid-size businesses. Rather than handing you a builder, the team designs, builds, connects, and runs the agents for you: AI receptionists and phone answering on a real phone number, voice agents, sales follow-up and SDR agents, customer support agents, email agents, marketing agents, appointment setters, and workflow automation — integrated with the tools the business already uses. The positioning is explicitly not another DIY toolkit: it is a finished agent build operated by AIQ Labs, the team behind the AI Business Sites platform. Target buyers are owner-operators and small teams in trades, legal, healthcare, insurance, real estate, ecommerce, and professional services who are losing missed calls, slow lead follow-up, and manual busywork. Engagements are month-to-month, the client owns everything built, and the starting point is a call to scope the agent for your business.
Pros
- Fully done-for-you: design, build, integration, and operation are handled by AIQ Labs
- AI receptionist answers calls on a real phone number, not just a browser widget
- Month-to-month with no long contract lock-in, and the client owns everything
- Covers more than voice: sales follow-up, support, email, marketing, appointments, and workflow automation
- Backed by the team behind the AI Business Sites platform
Cons
- You give up hands-on control of the agent's design compared with a DIY builder
- Requires a scoping call to start, so there is no instant self-serve launch
- Best fit is small and mid-size businesses; not aimed at teams that want to build many agents in-house
Pricing compared: per-minute platform vs scoped service
DIY control vs done-for-you operation
Reliability, compliance, and fit for small businesses

FAQs
How much does Synthflow AI cost?
Synthflow's published plans start at $29/month for Starter (50 minutes, 5 concurrent calls), then $450/month for Pro (2,000 minutes), $900/month for Growth (4,000 minutes), and $1,400/month for the white-label Agency plan (6,000 minutes). Enterprise contracts start at $30,000/year. Independent reviews report the real all-in per-minute cost lands around $0.15–$0.37 once LLM and telephony are included, with add-ons such as ~$20/month per extra concurrent call and a ~30% surcharge for a HIPAA BAA.
What is the difference between Synthflow and Agents by AIQ?
Synthflow is a DIY platform: you build, test, and maintain AI voice agents yourself in a visual Flow Designer, paying per-minute usage on published tiers. Agents by AIQ is a done-for-you service: AIQ Labs designs, builds, connects, and runs agents for your business — including an AI receptionist on a real phone number, sales follow-up, support, email, marketing, and appointment agents — on month-to-month terms where you own everything built.
Is Synthflow easy to use for non-technical small business owners?
For basic setups, yes: Synthflow holds a 4.5/5 G2 rating across 1,000+ reviews, with ease of use the most repeated compliment and some users going live in a day. However, reviewers also report a real learning curve once you build beyond simple flows, and some say the agent sounds like a polished IVR when callers go off script. If nobody on your team will own the builder, a done-for-you option like Agents by AIQ removes that work.
Does Agents by AIQ require a long contract?
No. Agents by AIQ engagements are month-to-month, and the client owns everything that is built. Work starts with a call to scope the agent for your business — covering needs like phone answering, lead follow-up, appointment setting, support, and workflow automation — integrated with the tools your business already uses.
