Professionals were still relying on paper business cards that got lost or thrown away. The challenge was to create a digital alternative that was actually easier to use. We built MIDIN as a subscription-based SaaS platform where users create a digital profile once and share it via QR codes, links, or NFC tap — no app download required for recipients. The key was making the onboarding under 2 minutes while supporting rich media profiles with team management for enterprises.
MIDIN launched successfully and onboarded 500+ users in the first quarter. The NFC card integration drove 40% of new signups. Average user session time is 4+ minutes, and the platform maintains 99.5% uptime. The subscription model achieved a 15% month-over-month conversion rate from free to paid tiers.
