Consider a scenario where a buyer lands on a website late at night and fills out a demo request form after showing his interest in a particular product. Since the buyer is interested in that product, he may be ready to explore it immediately. But the sales team may not be available at that time to address his request. This is the biggest challenge because he has to wait till a sales representative gets in touch with him and schedules a meeting to show the demo. For a B2B SaaS company, this limitation may become a major bottleneck. River AI is designed to address this problem. This article reviews River’s AI sales agent, which can drive live product demos and close deals.

River AI Sales Agent review
River (RiverGTM) is an autonomous, full-stack AI seller for B2B SaaS teams. It can conduct live, sub-second voice conversations, handle complex buyer Q&A, and drive real-time product demos directly inside a live browser environment. River’s AI sales agent, Liv, can engage with customers/clients in real time to address requests, answer questions, and demo the actual product through a live browser session. The goal of developing River’s AI sales agent is to give buyers an immediate sales experience, leaving human sales teams to focus on more complex problems.
River’s AI sales agent differs from traditional AI chatbots that primarily answer text-based questions. It is designed to join live sales conversations and take immediate action. Founders and lean sales teams waste countless high-value hours running repetitive discovery calls, initial product demos, and follow-ups-or lose leads when human representatives are offline. River solves this by providing a 24/7 AI sales representative that qualifies prospects, interacts naturally over voice, and physically operates the web app live during demo calls. Headless browser automation is one of River’s powerful features, enabling it to click, type, navigate, and demonstrate product features.
River’s integration of sub-second real-time speech processing, interactive avatars, multi-LLM routing, and headless browser automation makes it an operational AI agent instead of a conversational one. River can take real-time action. River’s sub-second real-time speech processing eliminates awkward pauses and delays, making conversations feel more natural and human-like. River is backed by a $2M early-stage investment led by founders of renowned companies, including Ramp, Kalshi, Lean, and JumpCloud.
How River’s AI sales agent works
River’s AI agent, Liv, works in the following 4 simple steps:

- Someone asks for a demo: When a user lands on a website and requests a demo, instead of simply presenting the calendar, the AI agent Liv connects with the user immediately. The real-time conversation begins within a few seconds. The user doesn’t have to wait for the product demo.
- Live product demonstration: The AI agent starts demonstrating the product. It can click, type, and navigate through the SaaS application while explaining the product during the video call.
- Follow-up: The AI agent Liv handles follow-ups through emails, calls, and reminders until the deal closes or is handed over to a human.
- Full transparency and real-time visibility: Every conversation is fully recorded, allowing human sales team executives to review interactions, track insights, and step in whenever needed.
Key features of River AI
Let’s talk about some key features of River AI.

- Real-time AI voice conversations: Liv can listen and answer in one second, which makes the conversation feel more natural rather than a chatbot-based interaction. It supports more than 40 languages, including English, French, Arabic, and more. The AI assistant can deliver human-like verbal interactions without a noticeable delay.
- Live In-browser product demos: Live In-browser product demos are a powerful feature of River. Today, most AI agents can answer users’ questions, schedule meetings, and send emails. Liv can operate the actual SaaS platform live in a browser window during the call to visually demonstrate features based on buyer prompts.
- Interactive AI avatars: For video calls, River uses an AI representative that has the face and voice of a human. This AI avatar gives users a visual human presence during live sales calls.
- Automated pipeline follow-ups: Liv can handle ongoing multi-touch follow-ups until a meeting is booked or the deal closes.
Core use cases of River AI
- Autonomous inbound sales demos: River can run initial product walk-throughs and answer technical questions instantly when a lead submits a demo request. For example, if a user submits a demo request outside business hours, River can start the conversation immediately instead of scheduling a call with a human sales representative.
- 24/7 global buyer coverage: River can engage prospects instantly, regardless of location or time zone. This helps companies effectively deal with international clients even when sales representatives are unavailable.
- Founder and lean team scale: River allows startups to scale GTM operations without hiring a large team of SDRs (Sales Development Representatives) and AEs (Account Executives).
- High-volume lead qualification: Since River can interact with a large number of prospects and identify potential buyers, it helps filter massive inbound lead lists so human sales executives can focus only on qualified buyers.

River’s pricing is customized based on your business requirements and usage needs. Because the platform supports different configurations, integrations, and LLM models, no single fixed pricing plan fits every business.

To get an accurate quote, businesses can schedule a call with the River team. During the consultation, the team will understand your requirements, recommend the appropriate setup and LLM model, and provide custom pricing based on your specific needs.
