StackPass is a product we built and run ourselves: a digital business card that lives in Apple Wallet as a native pass. The card is always in the pocket where phones already are, it shares with a scan, and it never goes out of date. The demo card on the homepage is Dan's own.
The problem
Ten billion paper business cards are printed every year and 88% are thrown away within a week. The ones that survive are outdated the moment anything changes: a new role means a new print run while 400 old cards sit in a box, and even a card that gets kept still needs someone to type every detail in by hand.
The digital alternatives usually swap one friction for another: an app the other person has to install, or a profile link that dies in a chat history. A card only works if it is effortless on both sides of the handshake.
The card
Your profile becomes a signed Apple Wallet pass with your name, title, company and a built-in QR code. It sits alongside boarding passes and payment cards, works offline, and is always one swipe away, with no app install on either side.
The person you meet scans the code and lands on your profile at your own vanity URL. A vCard prompt appears automatically: one tap saves your name, number, email, company and title straight into their contacts, on iOS or Android. The Wallet pass itself is Apple-only for now, but an Android recipient gets the identical web profile and one-tap save, so nobody is left out of the handshake.
Two minutes to a working card
Setup is deliberately shorter than ordering paper cards. Sign in with Google, GitHub or LinkedIn, add your details, and design the card in a split-pane editor with a real-time phone preview: five colour themes (Obsidian, Arctic, Sage, Blush and Copper), five font pairings and three layouts, 75 combinations in all. Publish, and the signed pass is generated and added to your Wallet in one tap.
Editing works the same way for the life of the card. The profile and QR code resolve to the latest version instantly, and on Pro every Wallet pass already issued updates silently over push. Change your title once and every card you have ever handed out is correct. Pro also adds analytics: profile views, Wallet saves and link clicks, broken down by platform.
One brand, every card
The Team plan turns the same card into company infrastructure. An admin sets the logo, colours, fonts and layout once and every member inherits them, locked, while people still own their personal details and links. New members join by magic-link invitation and have a branded card in seconds rather than waiting days for a print order. The team also gets a searchable public directory page, required-links control and a shared analytics dashboard.
The business
The free plan is a complete card, free forever: public profile with a custom URL, the Wallet pass with QR code, one-tap vCard saving, unlimited links and every theme. Pro is £5 a month for analytics, custom pass branding and a custom domain; Team is £15 a month per five seats with no per-user fees. The growth surface is built in rather than bolted on: comparison pages against Popl, HiHello, Blinq and Linq, industry landing pages for real estate, sales, freelancers, consultants and recruiters, and a blog.
Under the hood
The pass pipeline is the heart of the product: cryptographically signed .pkpass files generated per user, with silent updates delivered through Apple's push infrastructure as background jobs. Around it sits a modern TypeScript stack: OAuth sign-in, serverless Postgres, subscription billing, transactional email for the magic-link invitations, and rate limiting on the public surfaces.
Stack: Next.js, TypeScript, passkit-generator, Inngest, NextAuth, Drizzle ORM, Neon Postgres, Stripe, Resend + React Email, Upstash, Recharts
The honest part
StackPass earned its shape the hard way. The first version was a GitHub-powered developer profile network with wallet passes at its core, plus badges, teams and community hackathons. Around a hundred pull requests in, the lesson was unmissable: the wallet pass was the thing people actually used. So we rebuilt the product around the pass itself, for everyone who networks, not just developers.
Outcome
A live product that turns the oldest networking ritual into something that cannot go stale, and our working reference for Apple Wallet passes, push updates and freemium team billing: patterns we now reuse in client work.
