Handle More Calls with an AI-Powered Business Phone

What is Allo

Vendor's own claim

Allo is a mobile-first (iOS, Android, Mac, Windows) AI phone system aimed at small sales and support teams, built to replace legacy VoIP providers. allo_search_conversation_items, allo_send_sms, allo_get_team_outbound_analytics) so an AI assistant can search calls, draft/send SMS, and pull team analytics conversationally.

Ideal customer profile

Vendor's own claim

Sales managers, founders, and reps at small teams who rely heavily on the phone to close deals and want AI transcription, CRM sync, and an AI receptionist without adopting a large enterprise contact-center platform.

Who should look elsewhere

Our read

The vendor's own llms.txt states pricing as Solo at $18/mo and Business at $32/user/mo, while the live pricing page frames Solo as "Coming soon" and lists Business/Ultra prices in GBP (£25/user/mo Business billed yearly, £88/user/mo Ultra billed yearly) rather than USD - the two sources disagree on both currency and plan availability, so exact current pricing should be confirmed directly before budgeting. The most advanced AI Agent capabilities (AI SDR, AI Customer Support Agent, AI Lead Qualifier, custom AI agents) are gated to the top Ultra tier, so teams wanting more than basic AI summaries and CRM sync need the highest-priced plan.

Allo FAQ

Does the API cost extra?

No. Per the v1 API FAQ, API access is included with every Allo plan at no extra cost; the only charge is outbound SMS sent through /v1/api/sms, billed per segment like normal text usage.

From official docs
How much does Allo cost?

Sources conflict: the pricing page lists Business at £25/user/mo billed yearly (£35 monthly) and Ultra at £88/user/mo billed yearly (£110 monthly), with Solo marked "Coming soon"; the vendor's own llms.txt separately states Solo at $18/mo and Business at $32/user/mo. We report both and flag the discrepancy rather than picking one.

From official docs
Is there a free trial?

Yes, a 7-day free trial with no credit card required, per both the pricing page CTA and the llms.txt company facts.

From official docs
What CRMs does Allo sync with?

Native two-way integrations include Apollo, Attio, HubSpot, Notion, Odoo, Salesforce, Sellsy, Shopify, Streak, plus Zapier, Zoho Flow, and generic webhooks - 22 native integrations total per the integrations page.

From official docs
Is Allo SOC 2 or otherwise independently audited?

The llms.txt states AES-256 encryption, GDPR compliance, and that the product is "independently audited," without naming the auditor or standard in what we retrieved.
