ReplyAuto

What is ReplyAuto?
Reply Auto drafts replies for Facebook and Instagram comments on Shopify stores. It pulls comments from connected Meta accounts into one inbox, grounds each draft in your live catalog, policies, and FAQs, then lets moderators edit and send in one click or auto-post when the draft passes safety rules.
The product targets e-commerce teams that answer the same product, shipping, and sizing questions all day. Workspace owners connect Facebook Pages, linked Instagram Business accounts, and Shopify via Admin token. Reply Auto indexes products and brand context so drafts cite real stock, prices, and shipping windows instead of generic copy.
Pro and Enterprise plans add auto-reply mode, higher monthly reply limits, longer activity history, and team features like SSO. New accounts start on a 14-day Pro trial with no credit card required.
Opnbx.ai

What is Opnbx.ai?
Opnbx.ai is a B2B sales intelligence platform built around what the company calls Precision Prospecting. It gives sales and marketing teams a unified data layer to spot which accounts in their market are worth pursuing right now. The product focuses on ICP validation, intelligent segmentation, and account-level research rather than generic firmographic lists. Teams log in through app.opnbx.ai after booking a demo through the marketing site.
Most intent data vendors sell broad market signals that every competitor can buy. Opnbx.ai tries to correlate signals from your own closed-won deals with live account activity, then scores and prioritizes companies against that custom model. The homepage positions it as a replacement for stitching together a Franken-Stack of tools like 6sense, Clay, Bombora, and ZoomInfo. That trade-off is narrower fit modeling in one platform instead of buying the same commoditized feeds everyone else has.
It targets sales leaders, RevOps teams, and individual reps at B2B companies running outbound or pipeline development motions. Integrations listed on the site include Outreach, HubSpot, Salesforce, Salesloft, and Apollo.io. Customer testimonials on the homepage come from teams at Datavolo, Vial, Descope, and Pangia who cite faster account research and higher conversion rates after onboarding.
