Shortlist
Closest alternatives to Maven AGI
The ones people open most here come first, then the closest matches. How we rank
- 01
VeraDialVerified
AI receptionist and verified US/Canadian business line that answers calls and texts and places outbound calls.
From $14.99/monthWhy it's on this listOn the command line · PartlyThere is no VeraDial CLI, but developer terminal clients can attach to the read-only MCP server after a manual one-time approval, which gives terminal access to account records only.Source ↗
Where it improves on Maven AGI
- +How it meters · YesBilling is a flat monthly or annual subscription per plan with pooled minute allowances, explicitly not per seat and with no activation fee; extra lines are a fixed monthly add-on.Source ↗
- +Free tier · PartlyThere is no standing free plan, which the vendor states outright, but Vera Lite and Vera Plus each open with a 7-day free trial on capped minutes, Vera Business starts paid with no trial, and a browser demo needs no signup.Source ↗
Trade-offs against Maven AGI
- −Done-for-you service · NoYou run the software yourself: the vendor explicitly removes the onboarding call and sales demo, and setup is a self-serve number pick plus a website URL, though the Business tier suggests a pre-purchase scoping conversation.Source ↗
- −Agent permissions · PartlyEach line runs in approve mode or auto mode, so the owner decides per line whether Vera sends a reply herself; auto mode still falls back to human review when the model asks for a person.Source ↗
- −Claude · NoClaude is supported only as a client that reads your account through the MCP connector; the vendor's own complete list of voice providers for AI calls does not include Anthropic, so Claude does not drive the conversations.Source ↗
- 02
KalyvoxVerified
AI phone receptionist that answers inbound calls, qualifies them, transfers or books appointments.
From $95/monthWhy it's on this listHow it meters · YesBilling is a fixed monthly subscription chosen by team size plus metered voice usage at €0.19 (about $0.21) per minute of actual assistant conversation time, with no prepaid minute bundle and the same rate on every plan.Source ↗
Where it improves on Maven AGI
- +Free tier · PartlyYou can start without talking to sales or entering a card, but only for seven days: there is no standing free plan, and after the trial you either pick a paid plan or the account pauses.Source ↗
- +Getting out · YesData comes out in CSV from the dashboard and in a structured JSON/CSV portability request, deletion is available on request, and there is nothing to forfeit on exit because usage is billed after the fact with no prepaid minute bundle.Source ↗
Trade-offs against Maven AGI
- −GPT · PartlyThe only model-vendor disclosure anywhere on the site is a sub-processor entry naming OpenAI for voice processing and transcription; there is no plan row, docs page or settings screen that offers GPT as a selectable model, so this is a supply-chain fact rather than a supported-model claim.Source ↗
- −Model choice · NoThe agent-configuration guide enumerates exactly what a customer may change about the assistant's identity — name, voice and response style — and a model or provider choice is not among them anywhere in the dashboard documentation.Source ↗
- −API access · PartlyThere is a documented public REST API with bearer keys, ticket endpoints, cursor pagination and a ticket.created webhook, plus a public OpenAPI 3.1 spec — but key creation is only offered from the Pro plan upwards, so Solo customers cannot drive it from their own stack.Source ↗
- 03
MixdeskVerified
Omnichannel customer engagement platform with AI Agents for support, sales and lead qualification.
From FreeWhy it's on this listHow it meters · YesBilling is a flat monthly plan with usage allowances rather than seats: conversations, connected channel accounts and AI messages are metered, with extra AI messages sold in packs and WhatsApp fees billed by Meta.Source ↗
Where it improves on Maven AGI
- +Free tier · YesA standing Free plan costs nothing and needs no card, though it caps conversations at ten and excludes AI Agents entirely.Source ↗
- +Bring your own key · PartlyYou cannot supply your own inference key to the native AI Agent, but connecting a Dify or Coze bot means pasting your own provider API key, and a self-hosted Dify also takes your own API URL.Source ↗
Trade-offs against Maven AGI
- −Done-for-you service · NoYou run the software yourself on a subscription; the vendor sells plans and provides onboarding help on higher tiers rather than operating agents for you.Source ↗
- −Runs autonomously · PartlyAI Agents reply to customers around the clock without a person present, but they only act once assigned through an automation workflow and the vendor tells you to configure a fallback and human handoff.Source ↗
- −Agent permissions · PartlyOperators constrain the agent with a persona, linked knowledge bases, reply blocking for named keywords or intents, a configured fallback and a whitelist of contact fields it may read, but there is no documented approval step before an action runs.Source ↗
- 04
VoiceFleetVerified
Inbound AI phone receptionist for small businesses: answers calls, captures bookings, escalates urgent callers.
From €99/month (about $111)Why it's on this listHow it meters · YesBilling is prepaid minutes on a monthly plan, not seats and not per call: 500, 1,000 or 2,000 included minutes, with the vendor publishing approximate call equivalents of ~200, ~400 and ~800.Source ↗
Where it improves on Maven AGI
- +Free tier · PartlyThere is a free way in but no standing free plan: every tier carries a 7-day trial with no setup fee, after which a paid plan starting at EUR 99 per month is the only path.Source ↗
Trade-offs against Maven AGI
- −Agent permissions · PartlyScope is set by the customer rather than open-ended: instructions, approved FAQs, booking rules and escalation thresholds define what the assistant may do, and the terms require the buyer to keep a human fallback rather than rely on it alone.Source ↗
- −Model choice · NoThe buyer picks a plan, not a model: the stack is chosen and may be replaced by the vendor under the terms, and no model-selection control is published on any tier.Source ↗
- −In a browser · PartlyA hosted dashboard is where you configure and review calls, but the analytics dashboard is gated to Growth and Pro and multi-location management to Pro only, so the entry tier gets a thinner web surface.Source ↗
- 05
Cresta
Enterprise contact-centre platform with autonomous voice and digital AI agents plus real-time human agent assist.
Why it's on this listWrites code · PartlyConductor turns an approved agent blueprint into prompts, subagents, configs, tools and custom functions from natural language, but only for Cresta AI agents, not general application software.Source ↗
Where it improves on Maven AGI
- +Multi-agent · YesAgents are built as a decentralised network of specialised subAgents, each with its own prompts, knowledge, tools and guardrails, collaborating on one conversation.Source ↗
- +Single sign-on · YesCustomer SSO integration is not merely available, it is one of two mandatory authentication paths alongside Cresta two-factor authentication; the protocol, SAML or OIDC, is never named publicly.Source ↗
Trade-offs against Maven AGI
- −Agent permissions · PartlyAgents act within escalation policies, compliance boundaries and an always-on guardrail library, and supervisors can steer or take over a live call; Cresta publishes no per-action approval or confirmation model.Source ↗
- −Claude · PartlyAnthropic is named as a sub-processor supplying natural-language APIs, which is the closest Cresta comes to confirming Claude in its stack; buyers are never offered a named model to select.Source ↗
- −GPT · PartlyOpenAI and Microsoft are named sub-processors supplying natural-language APIs; model choice per task is not published.Source ↗
- 06
Sierra
Enterprise platform for customer-service AI agents across voice, chat, email and messaging, priced by outcome.
Why it's on this listWrites code · PartlyGhostwriter turns a prompt, an SOP or a transcript into a production agent journey with workflows and guardrails; what it authors is agent configuration, not application source code.Source ↗
Where it improves on Maven AGI
- +Open models · PartlySierra states it blends open-weight models into its constellation, but the buyer neither picks nor supplies them and no model names are published.Source ↗
- +In your editor · PartlyAgent SDK journeys are written in your own editor and software lifecycle, but Sierra ships no editor extension and the agent itself runs in customer channels.Source ↗
Trade-offs against Maven AGI
- −Claude · PartlyAnthropic is a named AI-services subprocessor, so Claude is in the mix, but Sierra routes models itself and never exposes a Claude selector.Source ↗
- −GPT · PartlyOpenAI is listed as an AI-services subprocessor, so GPT models are used under the hood, chosen by Sierra's router rather than by the buyer.Source ↗
- −Model choice · NoModel selection belongs to Sierra: it routes each turn to what it judges optimal and swaps providers on outages, with no published customer model choice.Source ↗
- 07
AiZipZapVerified
Customer intake agent that turns each request into a job brief, missing questions and a reply draft.
From FreeWhy it's on this listHow it meters · YesBilling is a flat monthly fee for a handoff allowance rather than per seat or per token, and the vendor rules out overages and token charges outright.Source ↗
Where it improves on Maven AGI
- +Free tier · YesA standing free tier runs real requests through the manual agent with no account and no card, capped at three successful handoffs per network each UTC day.Source ↗
Trade-offs against Maven AGI
- −Runs autonomously · PartlyCollection, saving, drafting and notification run without a human, but the vendor stops deliberately at the draft: the owner reviews, edits and sends every reply themselves.Source ↗
- −Multi-agent · NoOne drafting pass per request is described throughout; the vendor's concurrency statement describes shared generation capacity, not agents coordinating on a task.Source ↗
- −Agent permissions · NoThe agent has no permissions to spend: the vendor lists inbox access, reply sending, code execution and business-system access as things it cannot do at all.Source ↗
- 08
Ada
Agentic customer experience platform running AI support agents across voice, messaging and email.
Why it's on this listWrites code · PartlyAda does not write application code, but code tools are small Python functions a buyer can have drafted from a plain-language description through Ada's MCP Server, staged and promoted by a person.Source ↗
Where it improves on Maven AGI
- +Open models · PartlyAda internally hosts open-source LLMs for contextual understanding only; reply generation runs on the commercial providers and the customer selects neither.Source ↗
- +In your editor · PartlyNo coding-agent IDE surface, but Ada's MCP server can be connected from Cursor and VS Code, which lets a team manage and tune the agent from an editor rather than build software in one.Source ↗
Trade-offs against Maven AGI
- −Agent permissions · PartlyThe agent only runs tools an admin has activated, and Ada's own recommendation is to keep write tools behind a Playbook step so they execute inside a controlled flow rather than at the model's discretion; MCP tools are discovered but disabled until enabled.Source ↗
- −Model choice · NoAda chooses the models: it benchmarks a curated portfolio on accuracy, safety, latency and cost and promotes versions through its own evaluation pipeline, so model selection is the vendor's decision rather than a customer setting.Source ↗
- −Pooled budget · PartlyConsumption is metered per end-user conversation at the agent level rather than against per-user allowances, but no balance, pool or overage mechanics are published.Source ↗
- 09
Fin
Intercom's customer agent that resolves support conversations across chat, email, voice and social channels.
From $0.99/outcomeWhy it's on this listHow it meters · YesBilling is per resolved outcome rather than per seat or per token, with a second, ten-times-higher rate for sales qualifications and no charge for a conversation simply passed to a human.Source ↗
Where it improves on Maven AGI
- +Free tier · PartlyYou can start without a sales call, but only on a 14-day cardless trial: there is no standing free plan, though eligible early-stage startups get a year of Fin free under a separate programme.Source ↗
Trade-offs against Maven AGI
- −Claude · PartlyAnthropic is one of the providers Fin falls back to for resilience, but the answer model is Intercom's own Apex and the buyer is not offered a model picker, so Claude is under the hood rather than selectable.Source ↗
- −GPT · PartlyOpenAI models are part of the same automatic failover pool as Anthropic and Google, so GPT is used by the platform but is not a model the customer chooses or configures on any tier.Source ↗
- −Model choice · NoThe vendor chooses the model, not the buyer: answers come from Intercom's purpose-trained Apex suite and third-party providers are swapped in automatically, with no model selection published on any plan.Source ↗
What to watch for
- CrestaFull-platform pricing (AI Agent, Conversation Intelligence, Knowledge Agent) is not published, only the narrower Agent Assist SKU has any public price.
- SierraNo public sign-up, pricing page or self-serve API, access is via an enterprise sales engagement.
- AdaEnterprise, sales-led only. No self-serve signup, no public pricing and no free trial.
- FinWhat counts as a billable "resolution" includes soft outcomes (customer stops replying), which can inflate spend relative to true resolutions.
