Founded in 2025 by Raj Maddula and headquartered in Irvine, California, the company operates with 11 to 50 employees. It addresses a critical execution gap in outbound sales development: while email-only AI BDRs struggle with declining inbox reply rates, human SDR teams rarely have the bandwidth to follow up with every lead immediately across phone, SMS, and email simultaneously. ### How Squirrels works At the technical core of Squirrels is a multi-agent orchestration engine that combines a 275M+ B2B contact database with autonomous voice, SMS, and email AI agents. Users configure their target ideal customer profile (ICP) and campaign offer, and Squirrels' prospecting agents automatically source and enrich up to 18,000 prospects per year on its core plan. The platform then executes synchronized multi-channel sequences—sending personalized cold emails, placing natural-sounding AI voice qualification calls, and following up via SMS. When a prospect responds or picks up the phone, the AI agent handles initial discovery questions, verifies budget and timeline criteria, and books meetings directly onto the human sales team's calendar while syncing call transcripts and notes to the CRM, alongside native workflow integrations for HubSpot and Zapier. ### Limitations Operational considerations and platform boundaries include: - **Primary Operational Trade-Off**: In practical enterprise deployments, the primary trade-off is that automated AI voice calling and SMS outreach require strict adherence to regional telecommunications compliance (such as TCPA opt-in rules in the United States) and careful caller-ID reputation management. - **Functional Scope Boundary**: Squirrels is not built for B2C eCommerce storefront merchandising, long-form SEO content publishing, or enterprise Marketing Mix Modeling (MMM). - **Deployment & Governance Considerations**: Additionally, highly technical enterprise deals with complex architectural questions still benefit from human sales engineer involvement after initial qualification. ### Squirrels pricing Squirrels offers transparent tiered pricing starting at $399/month for core workflow automation and $499/month (billed annually) for its flagship AI SDR tier covering up to 18,000 prospects per year, alongside a $1 trial option and custom enterprise packages. ### How Squirrels compares In the autonomous B2B sales agent and AI SDR market, Squirrels competes with 11x.ai, Artisan, AiSDR, Bland AI, and Apollo.io.
