Ada

Ada is the Agentic Customer Experience (ACX) company that helps organizations build, manage, optimize, and scale AI agents for customer service, with more than 550 AI agents deployed globally. Ada's core differentiator is the ACX Operating Model: the only approach in the category that pairs an enterprise AI platform with structured methodology and expert guidance. The logic behind it is direct: the best customer experiences come from businesses that own and operate their AI agents, not ones that depend on vendors to run them. The companies that own their AI capability are the ones that compound value. Ada's job is to help them get there. Ada delivers that ownership through three components: - ACX Platform: AI agent management across every channel and language, no engineering dependency required - ACX Practice: A structured methodology for building, governing, and scaling an ACX program - ACX Experts: Who work alongside internal teams to build lasting AI fluency The ACX Platform is designed with these core components: - Reasoning Engine™: An unified intelligence layer that powers the AI agent across all CX channels using shared customer context, business logic, and configurable policies, with built-in accuracy and safety controls. Consistent experience meets reduced overhead. - Conversation Hub: Deploy an AI agent across voice, messaging, email, and custom channels in 60+ languages, with structured handoff to human agents when escalation is needed. - Performance Center: Tools for building, testing, and optimizing AI agent behavior, including Playbooks for complex multi-step workflows (refunds, rebookings, authentication), Coaching for continuous improvement, and Simulations for safe pre-launch testing. Tracks resolution rate, CSAT, NPS, and custom KPIs. - Developer Toolkit: Pre-built connectors for Salesforce, Zendesk, and ServiceNow, plus APIs, SDKs, and an MCP Server for managing the AI agent from tools like Claude or ChatGPT. - Enterprise-grade security: SOC 2 Type II, GDPR, HIPAA, PCI DSS, and AIUC-1 certified, with Zero Data Retention and regional data residency. Ada was the first ACX platform to have achieved AIUC-1 certification, the world's first AI safety standard specifically designed for customer service agents—and Ada helped write it. Proven customer outcomes include: - IPSY (ecommerce) achieved 943% ROI on its AI investment within four months of using Ada's ACX platform alongside a 63% improvement in automated resolution rate and a 41% improvement in CSAT. - Endy (retail) achieved an 85% automated resolution rate during a major national promotion and 75% CSAT during their warehouse sale. - eSky Group (travel) saw a 17-point increase in automated resolution in four months, a 19-point CSAT jump, and 200% ROI—running three brands across 50+ markets with one team on one platform. - Blackhawk Network (fintech) transformed into a mature ACX operation, automatically resolving ~50% of all incoming inquiries across brands and channels, and upskilling frontline agents with plans to expand AI across the entire enterprise.

Afterhour

Afterhour.ai is an AI-powered call answering and intake platform built exclusively for law firms. It ensures firms never miss a call by providing always-on, natural-sounding AI agents that answer, screen, and capture every lead 24/7/365—even when human staff is offline. Instead of simple message-taking, Afterhour engages callers in full conversations, gathers key case details, and routes high-value opportunities back to the firm in real time. Designed specifically for plaintiff and consumer-focused practices (including personal injury, workers’ compensation, mass tort, and criminal defense), Afterhour helps firms stay responsive during nights, weekends, and holidays without adding headcount or overloading in-house teams. Firms can configure custom scripts, greetings, and escalation rules so every call reflects the firm’s brand and intake criteria. Urgent matters are flagged and escalated to on-call contacts, while non-urgent calls are summarized and delivered through detailed morning reports.

Agent247

Agent247 is an AI voice agent that lives on your website — not a chat widget, a voice. Drop in one script tag and it comes alive knowing nothing about your site. Every turn, it reads the live page so it always knows exactly what's in front of the visitor. It doesn't just answer typed questions and stop. It talks, and it shows: it greets every visitor the moment they land, in their own language, then walks them through your live product out loud — highlighting what matters, pointing the way, and telling them exactly where to click, like a rep on a screen share. From there it handles objections, points visitors to the right plan, and keeps the momentum going all the way to a completed checkout. Setup takes minutes. You don't need docs or a polished knowledge base to train it — just click through your own product once and talk it out loud, and Agent247 runs that same demo for every visitor after, forever. It works with any stack — Webflow, WordPress, Shopify, Framer, Wix, React — and speaks 100+ languages, so visitors who'd normally bounce because of a language gap get answered instantly instead. It also compounds: every conversation it has teaches it more about who buys, what wins them over, and where deals quietly slip away — so it gets sharper the longer it runs. Agent247 is built for one problem: your funnel leaks the moment nobody's there to answer a question — at 2am, on a "book a demo" form, in a support queue. Agent247 is always there. Currently pre-launch, in early access.

Agent360

Agent360 is an AI-powered go-to-market platform for outbound teams — built with recruiting first in mind, but not limited to recruiting. It brings together the pieces teams normally buy from separate vendors: a B2B contact and company database, data enrichment, multichannel sequencing across email and LinkedIn, and the email deliverability infrastructure (inbox warmup, sending rotation, spam and placement monitoring) that keeps campaigns landing in the primary inbox. On top of that sits a layer of AI agents that research each contact, draft personalized openers and follow-ups, detect and classify replies, and decide when to advance, pause, or hand a conversation to a human. BUILT FOR RECRUITING AND STAFFING Agent360 treats a requisition the way a sales tool treats a deal. Source candidates, enrich them with work history, skills, and verified contact details, then launch a req-specific outreach campaign that keeps warm candidates nurtured between roles. Recruiting and staffing teams use Agent360 for passive candidate sourcing, re-engaging stale candidate databases, recruitment marketing campaigns, client-side business development outreach, and automated interview scheduling. Sync with applicant tracking systems and recruiting CRMs keeps candidate records, pipeline stages, and activity history consistent, so Agent360 works alongside your ATS rather than replacing it. ALSO FOR SALES AND REVENUE TEAMS The same engine powers conventional outbound motions: ICP list building, buying-signal and intent-based triggers, account and prospect research, lead scoring and routing, multi-inbox sending at volume, and campaign reporting. SDR teams, founders, and agencies running outreach on behalf of clients use it the same way recruiters do. HOW BUYERS EVALUATE IT Agent360 is typically compared against assembling a stack — a sales intelligence tool such as Apollo.io for data, a sequencer such as Instantly for sending and deliverability, Clay for enrichment and AI research, and a recruiting CRM such as Bullhorn for candidate outreach. Agent360 consolidates those jobs into one workspace with a single view of every contact, campaign, and reply. KEY CAPABILITIES Contact and company data, data enrichment, email verification, multichannel sequencing, inbox warmup and deliverability monitoring, AI-written personalization, AI research and qualification agents, candidate sourcing, candidate nurture, ATS and CRM sync, reply detection and unified inbox, meeting scheduling, lead scoring, and campaign analytics.

AgentCallback

AgentCallback is a Voice AI platform that manages calls at scale - 24/7, multilingual, always available. Businesses lose revenue from missed calls during weekends, after-hours, holidays, and peak times. Long wait times and complex IVR systems create poor customer experiences and lower CSAT. Companies also face rising costs from agent burnout, high turnover, and hiring. Expanding into new regions requires costly multilingual teams, which makes global scaling harder. AgentCallback solves these challenges with real-time voice AI agents that answer questions, qualify leads, book appointments, run surveys, and route calls. The platform uses speech-to-speech models, enabling voice understanding without traditional text pipelines. This means faster responses, natural conversations, interruption handling, and background noise handling. With low latency and scalable architecture, AgentCallback helps businesses answer every call, deliver consistent global experiences, and scale voice operations at a lower cost.
