Bigly Sales is a managed AI outbound calling system built for organizations that want to automate outbound sales and lead engagement without separately assembling telephony, compliance, integrations, and AI voice technology. The platform provides the infrastructure required to run campaigns, including phone-number procurement, carrier registration, whitelisting, local presence dialing, spam monitoring, and number management. Bigly also integrates with CRMs, lead sources, internal systems, and APIs so campaign results flow directly into existing revenue operations workflows. Its compliance layer is designed to apply federal and state calling rules before each dial, including consent requirements, calling windows, opt-out handling, suppression, and other TCPA-related restrictions. AI voice agents can contact leads quickly, conduct scripted or dynamic conversations, collect qualification information, schedule appointments, transfer prospects to sales representatives, and trigger follow-up actions. The system records calls and produces transcripts, dispositions, structured qualification responses, conversion statuses, and other data for each interaction. Teams can also review aggregate metrics such as call volume, answer rates, success rates, performance by lead source, live transfers, scheduled meetings, SMS triggers, contracts sent, and payment links delivered. Bigly provides ongoing optimization by monitoring campaign results, refining prompts, adjusting qualification logic, and troubleshooting performance issues over time. The managed-service approach also includes campaign setup and a dedicated account representative rather than requiring customers to configure every technical component themselves. Bigly supports more than 30 industries, with use cases spanning B2B sales, financial services, insurance, healthcare, home services, ecommerce, real estate, lending, education, telecom, legal services, dealerships, and other outbound-driven organizations.
