StackAI is an enterprise AI automation platform built to help organizations create end-to-end internal tools and processes with AI agents. Unlike point solutions or one-off chatbots, StackAI provides a single platform where enterprises can design, deploy, and govern AI workflows in a secure, compliant, and fully controlled environment. Using its visual workflow builder, teams can map entire processes — from data intake and enrichment to decision-making, reporting, and audit trails. Enterprise knowledge bases such as SharePoint, Confluence, Notion, Google Drive, and internal databases can be connected directly, with features for version control, citations, and permissioning to keep information reliable and protected. AI agents can be deployed in multiple ways: as a chat assistant embedded in daily workflows, an advanced form for structured document-heavy tasks, or an API endpoint connected into existing tools. StackAI integrates natively with Slack, Teams, Salesforce, HubSpot, ServiceNow, Airtable, and more. Security and compliance are embedded at every layer. The platform supports SSO (Okta, Azure AD, Google), role-based access control, audit logs, data residency, and PII masking. Enterprises can monitor usage, apply cost controls, and test workflows with guardrails and evaluations before production. StackAI also offers flexible model routing, enabling teams to choose between OpenAI, Anthropic, Google, or local LLMs, with advanced settings to fine-tune parameters and ensure consistent, accurate outputs. A growing template library speeds deployment with pre-built solutions for Contract Analysis, Support Desk Automation, RFP Response, Investment Memo Generation, and InfoSec Questionnaires. By replacing fragmented processes with secure, AI-driven workflows, StackAI helps enterprises cut manual work, accelerate decision-making, and empower non-technical teams to build automation that scales across the organization.

Sellio is a cloud-based customer support platform specifically designed for small teams managing interactions across multiple websites and messaging services. It features an integrated live-chat widget that can be easily embedded, alongside a shared inbox capable of consolidating communications from website chats, email, and popular messaging platforms such as WhatsApp, Instagram, Facebook Messenger, Telegram, and SMS via Twilio; moreover, teams can also handle discussions originating from Slack and Discord. Members of the team have the ability to assign conversations, add internal notes, view customer histories, and efficiently streamline their responses. AI agents are designed to handle inquiries from website chats using a business's unique content, with the capability to escalate conversations to human agents when necessary; however, it's important to note that AI responses are limited strictly to website interactions, while all other communication channels require human management. In addition to its chat functionalities, Sellio offers ticket management, customizable routing rules, automated workflows, pre-saved responses, comprehensive customer profiles, feedback options, and support analytics. This platform is especially advantageous for SaaS companies, online retailers, and any small teams focused on enhancing their customer support efforts. A free plan is available, while subscription levels offer extra seats, channels, automation capabilities, and allowances for AI usage, making it an adaptable option for expanding businesses. Furthermore, Sellio's goal is to foster better team collaboration and heighten overall customer engagement through its wide array of features, ultimately leading to a more effective support experience. Each of these elements contributes to a more cohesive and productive customer service environment, ensuring that teams can meet their clients' needs efficiently.
