Simple AI

Simple AI is a voice AI agent platform that automates inbound and outbound phone calls for business sales and customer support. Founded by Catheryn Li and Zach Kamran, the company has raised $14 million in seed funding from First Harmonic, Y Combinator, and other investors. Simple AI targets consumer-facing businesses that handle high volumes of phone calls, particularly in sales, support, and lead qualification.

Key Features

• Voice AI Agents: Simple AI deploys AI agents that handle phone conversations from start to finish without scripts or decision trees. The agents understand context, handle objections, and carry conversation history across the full call and across a customer's entire history with the business.
• Low-Latency Architecture: The platform keeps end-to-end latency under 850 milliseconds, including voice activity detection, transcription, inference, and text-to-speech. This enables natural, human-like conversations at scale.
• Product Knowledge Ingestion: The platform ingests a company's full product catalog including SKUs, metadata, and pricing. AI agents use real-time customer data to personalize each interaction and can place orders or upsell products during calls.
• Warm Call Transfer: When a call requires human intervention, the AI agent seamlessly hands off to a human representative with full conversation context preserved.
• Knowledge Base Access: Agents access the business's entire knowledge base in real-time, providing accurate answers to customer questions about products, policies, and availability.
• Analytics and Insights: Every call produces a complete transcript, summary, and actionable insights. Businesses can review and score 100% of calls to identify trends and improve performance.
• Experimentation Tools: Users can tune each voice agent's speed, gender, and accent, and customize calls with customer preferences, purchase history, and other contextual data.
• Multi-Language Support: Simple AI speaks 29 languages and can place calls in 33 countries, providing global coverage with natural language support.

How It Works

Simple AI's system runs multiple proprietary AI models concurrently on every call. When a customer calls a business using Simple AI, the system processes raw audio packets through models that handle voice activity detection, end-of-turn recognition, transcription, natural language inference, and text-to-speech generation. The platform learns from the business's best sales representatives by analyzing call transcripts to replicate top-performer quality. Businesses deploy the agents through a workflow system that can be set up in minutes, and the AI maintains consistent performance that does not degrade with shift length or call volume.

Use Cases

• Inbound Sales: Simple AI fields incoming sales calls, knows every product detail, and handles upselling and cross-selling. Early customers include Omaha Steaks, DoorDash, and X.ai.
• Customer Support: The platform handles customer service inquiries, order status checks, returns, and billing questions with the same product-level knowledge as the sales use case.
• Lead Qualification: AI agents qualify inbound leads, collect contact information, and warm-transfer qualified prospects to human sales representatives.
• Customer Surveys and Data Collection: Automated outbound calls collect feedback, conduct surveys, and gather customer data.
• Debt Collection: Simple AI handles initial collection calls with consistent messaging and compliance guardrails.

Security and Compliance

Simple AI maintains SOC 2 Type II certification and HIPAA compliance for handling sensitive phone conversations and customer data. The platform provides automatic PII redaction that detects and removes sensitive information such as credit card numbers and social security numbers from transcripts and analytics. All phone conversations and transcripts are protected with AES-256 encryption, both during calls and in storage.

Availability

Simple AI originally launched as a consumer iOS app on the App Store, helping individuals make calls for restaurant reservations, appointment booking, and customer support. The company has since pivoted to focus on business-to-consumer voice sales, offering an enterprise platform. Pricing is not publicly listed and requires contacting Simple AI's sales team.
