About
Nimbus gives you an AI-driven agent workforce, covering voice calls, SMS, email, and chat, that engages your customers 24/7, automates tasks like lead qualification, appointment setting, client intake and support, and boosts conversion and outreach while reducing operational cost. It lets you build and train agents without code, upload your own knowledge base (PDFs, Word docs, webpages), set guardrails to keep responses accurate and brand-aligned, run AB tests, and preview behaviors before launch. Your agents can carry conversations across channels with full context, hand over to a human seamlessly, speak 40+ languages, and integrate with CRMs like Salesforce and HubSpot. A live dashboard tracks every metric you need, engagement, tasks completed, performance trends, and the system is built for rapid deployment in days, not weeks.

About
StackAI is an enterprise AI automation platform to build end-to-end internal tools and processes with AI agents in a fully compliant and secure way.

• Deploy AI agents as chat assistants, advanced forms, or APIs integrated into Slack, Teams, Salesforce, HubSpot, or ServiceNow.

• Route across OpenAI, Anthropic, Google, or local LLMs with guardrails, evaluations, and testing.
• Start fast with templates for Contract Analyzer, Support Desk, RFP Response, Investment Memo Generator, and more.
