About

Prosyo is an all-in-one B2B multichannel outbound OS for founders, agencies, and sales teams. It eliminates "franken-stacks" by combining intent data, LinkedIn automation, and cold email into a unified workflow. Key features: Intent-Led Outreach: Target buyers based on active signals. De-anonymize website visitors, track LinkedIn post engagement, monitor job changes, and capture hiring signals to trigger timely campaigns. Multichannel Sequences: Automate LinkedIn touchpoints and cold emails in one seamless flow with smart, rules-based branching. AI Integration: Connect ChatGPT or Claude (via MCP) to automatically draft hyper-personalized icebreakers based on prospect data. Unified Inbox: Manage replies across all client LinkedIn and email accounts from a single dashboard. Sequences auto-pause on reply. Agency Scale: Separate client workspaces, robust safety limits to protect accounts, and native webhooks/API.

About

Sellvance is a GTM experimentation platform for B2B SaaS teams still searching for product-market fit. Validate an ICP, test an offer, or check demand for a feature by talking to real prospects. Most cold email tools are built for volume. But zero replies can mean nobody wants your product, or that your emails never reached the inbox. Sellvance tells them apart. Every experiment gets a Signal Check: a delivery verdict (did the emails arrive?), an interest verdict (is the positive reply rate above your threshold?) and a harm verdict (unsubscribes). Until delivery is confirmed, Sellvance won't let you judge the reply rate. Includes a 9.5M+ company database, enrichment with AI agents, AI-written messages, in-app domains and mailboxes, deliverability monitoring, and an MCP server to run campaigns from Claude. Free Experiment Plan, no domain or mailbox needed. Paid plans from $199/month.
