The Responsible AI-Agent for organizations where the answer HAS TO BE RIGHT. kama.ai answers from knowledge your team approves, not from what a model guesses. Every response is accurate, consistent, and traceable to its source. Governed by design. How it works: At its core, the kama.ai REACTT Agent™ runs on a deterministic Knowledge Graph AI that delivers 100% accurate answers with trusted Intelligent Automation. Human-in-the-loop gives you a governed, continuously improving system with an audit trail. Want generative AI too? REACTT SourceLock™ lets you use the LLM of your choice, answering only from your website content or Trusted Collections (your curated company documents). Need multi-step tasks done? Add Intelligent Automation that completes them through simple chat. Your overall result: a purpose-built AI Agent platform with a clear ROI, focused on revenue growth and lower internal costs. No hallucinations. No rogue agents. Full brand safety. Fast deployment. Why it's different: Most AI chatbots generate first and add guardrails afterward. kama.ai works the other way around: Deterministic AI first to guide and orchestrate. Then generative AI helps only where you allow it. This lowers the risk of AI adoption for teams that can't afford a wrong answer about a permit, a policy, the way to fix an expensive machine on the line, a procedure, or their brand. Built for: manufacturers, municipalities, government, colleges and universities, professional services, non-profits, museums, and Indigenous services organizations. Purpose-built to be transparent, accountable, and culturally aware. Sign up for a FREE Trial. Get the right information to the right people, at the right time. Accurate. Accountable. Trustworthy AI.

Bigly Sales is a fully managed AI calling platform for sales teams, lead generation companies and call centers. AI voice agents call, qualify, nurture and live-transfer leads around the clock, answer inbound calls, and book appointments, while every outcome writes back to your CRM. You don't assemble the stack yourself. Bigly writes your call scripts with Claude, ChatGPT and other leading LLMs, then tests script versions against each other on live traffic and keeps the one that converts best. Phone numbers, carrier registration, more than 200 whitelisted lines with local presence, spam monitoring, call routing and campaign setup are handled for you before the first dial. Each call is checked against consent, suppression lists, known TCPA litigants and state and federal calling rules, including quiet hours, before it is placed. Reporting is built around the result you pay for. The dashboard tracks success rate per lead, cost per transfer and cost per human contact, plus a dial-to-transfer funnel that shows where calls drop off: no answer, DNC request, failed qualification, or a transfer the agent never picked up. Leads can arrive in real time from API vendors or as uploaded lists, and every source is ranked by success rate and cost, so you can see which lead vendors pay off. An hour-by-hour view shows when your leads actually convert. The Bigly Sales MCP server lets you run the account by asking Claude or ChatGPT: add leads to an active campaign, check pacing and minute usage, pull call summaries and transcripts, or find out who picked up today and wants a demo. Common uses include aged and dead lead reactivation, speed-to-lead follow-up on web and vendor leads, appointment setting, inbound answering and overflow, and warm transfers to licensed agents in insurance, lending, home services, legal, auto and political fundraising. Integrations include HubSpot, Salesforce, Zoho CRM, Pipedrive, GoHighLevel, Close, Follow Up Boss, Keap, monday CRM, Freshsales, ActiveCampaign and Microsoft Dynamics 365, plus an API for real-time lead posting. Plans start at $99 a month for 500 minutes, and Hunter, Closer and Rainmaker add a dedicated account manager who watches results and tunes your campaigns. New customers start with a free 30-minute AI calling setup ($3,000 value): the team builds your calling system live, shows the MCP and runs a test call.
