Company profile
researched Aug 2026Sento AI offers an AI voice agent service for outbound and inbound sales calling. Customers upload a lead list as an Excel or CSV file and start a campaign; AI agents then place calls around the clock across time zones, qualify prospects and book meetings. The company states its agents can hold human-like conversations, with natural pauses, emotions and adaptive responses, in more than 50 languages and voices, and that test calls can be run before a campaign goes live.
The product includes a dashboard covering live call monitoring, voice and script configuration (including voice personality settings and custom script upload), campaign performance reporting (calls made, connect rate, meetings booked, show rate, deals closed, win rate, and daily/weekly trends), lead management with CSV import and lead scoring, and call analytics such as sentiment, interest and detected objections. Calls are recorded and transcribed, with transcripts and downloadable reports available, and qualified leads and status updates (interested, not interested, callback) are synced automatically to CRM systems, with HubSpot and ActiveCampaign integrations named. Sento AI also positions the offering as a managed service, handling campaign setup, monitoring and optimization on the customer's behalf, along with the underlying technical infrastructure.
On data handling, the company says customer data is encrypted in transit and at rest and is not shared with or used to train external AI models.
Business model
Sento AI sells an AI calling capability as an alternative to hiring and training human sales development representatives, framing its value against stated SDR costs of over €40,000 per year per rep, high turnover, long ramp-up times and inconsistent pitch quality. Delivery is managed for the customer: Sento AI runs setup, 24/7 monitoring and optimization of campaigns, along with security and infrastructure, while the customer focuses on closing deals. Prospective customers are directed to book a strategy call with a strategist rather than to self-serve sign-up or published pricing.
▸Full profile — market position, technology, go-to-market
Market position
Positioning centers on replacing or augmenting human SDR capacity: agents that operate 24/7 across time zones, coverage of 50+ languages and ultra-realistic voices, same-day progression from lead list to booked meetings, pre-launch test calls, and a fully managed service in which Sento AI handles setup, monitoring, optimization and infrastructure. The company also emphasizes customer data ownership, encryption in transit and at rest, and a commitment not to share data or use it to train external AI models.
Technology
The offering is built around AI voice agents that conduct human-like conversations in more than 50 voices and languages, with natural pauses, emotional expression and adaptive responses, and that handle both outbound and inbound calls. Supporting components include campaign automation triggered by a CSV or Excel lead upload, lead scoring, call recording and transcription, conversation analytics that detect sentiment and objections and identify better-performing scripts, and automated CRM synchronization with HubSpot and ActiveCampaign. The company states data is encrypted in transit and at rest and is not used to train external AI models.
Go-to-market
Direct sales led by a "Book Strategy Call" call to action on the company website, with prospects routed to a conversation with a strategist. The site references existing clients without naming them.
Sales organizations that run cold-calling and outbound prospecting at scale and want to expand outreach without adding headcount, including teams currently employing or planning to employ SDRs. Multilingual support across 50+ languages and 24/7 calling across time zones point to customers running campaigns in multiple markets.
