Self-hosted team digital business cards to avoid SaaS lock-in

Sales and networking teams — from small agencies to mid-market and enterprise IT buyers — are increasingly frustrated by SaaS lock-in, lack of data portability, and limited administrative control over employee contact profiles that spread across events and CRM systems. The rise of QR-first exchanges at conferences and meetups has made digital cards a basic utility, but current offerings often force teams into hosted plans that complicate compliance and exit scenarios. You could build a self-hosted, optionally open-source digital business card platform that supports team provisioning, SAML/SSO, role-based branding, bulk vCard export, per-user analytics, and embeddable QR/pages that work offline as PWAs. Offerings would include an on-prem/docker deployable core, a managed-hosted tier for smaller teams, and paid add-ons (enterprise support, integrations with Salesforce/HubSpot, and white-labeling) to create multiple revenue streams. The timing is favorable: the addressable market is roughly 50 million businesses and a $6.0B annual market at an average spend of $120/year, while trends toward contactless networking, privacy/data portability, and open-source adoption lower resistance to self-hosting. Enterprises increasingly prefer vendors that allow export and auditability, which creates a clear entry point for a product that solves compliance and vendor-lock-in pain. To stand out you must deliver a secure, easy-to-deploy experience with enterprise-grade controls and an extensible API, while also providing a frictionless migration path from popular SaaS tools and a polished hosted option for non-technical teams. Expect strong differentiation on compliance and total cost of ownership but also significant go-to-market challenges given high competition and potentially slow enterprise sales cycles; realistically this maps to a high market score (92/100) and solid revenue potential (78/100) if you can execute the trusted-deployment and integration playbooks.
