Reversecontact Enrichment Alerts for Indie SaaS Founders

Problem: Indie SaaS founders drown in trial signups but have no fast way to tell a hobbyist tinkerer apart from a decision maker at a target account. Manually copy-pasting emails into an enrichment tool and checking dashboards is slow, and by the time a founder notices a VP from a mid-market company signed up, the trial window has partly elapsed. Named product: SignalDesk (working name) is a lightweight monitoring layer that watches your signup email stream and fires Slack alerts only when a high-value company or role registers. Solution: Connect your signup source (webhook, form provider, or auth provider), define what high-value means to you (company size, seniority, domain type, funding stage as available), and let reverse email enrichment score each new signup. When a match crosses your threshold, a Slack message lands in the channel with the person, their role, their company, and a one-click prompt to start outreach. MVP: A single Slack integration, one inbound webhook for signups, reverse email enrichment via an upstream provider, and a simple rules editor for who counts as high-value. No dashboards, no CRM, just the alert. Revenue: Flat monthly subscription with tiers based on enriched signup volume, target $29 to $99 per month per founder, matching the sub-$2500 MRR reality of comparable enrichment micro-tools. GTM: Launch in indie founder communities and Show HN, publish a teardown showing how to prioritize trial signups. Growth loops: Every Slack alert can carry a small attribution footer, and founders who see the value on trial signups tend to invite teammates to the alert channel, spreading the tool inside the workspace.
