Building the Operating System for Professional Networking
Cardixx is a professional networking platform built around a simple object: a digital business card people actually enjoy handing over. As Co-Founder and CPO I own the product end to end: strategy, architecture, design direction, monetization and go-to-market.
I lead a team of up to twenty across product, design, marketing and sales. Thirteen months after the first concept, Cardixx launched on the App Store and Google Play, live in Austria and Turkey on day one, with partner coworking spaces and networking hubs in both markets. This page is the story of the decisions that got it there.

Cardixx gives professionals a card that is always current everywhere it lives, and gives coworking spaces, hubs and event venues a networking layer their members actually use. One platform carries the card, the check-in, the discovery, the messaging and the analytics, for both sides of the exchange.

The Friction in Professional Networking
In 2026, professional networking still works the way it did twenty years ago. Paper business cards get exchanged and lost, follow-up dies by the next morning, and the coworking spaces, hubs and event venues that host all of this networking capture none of the value they create.
Cardixx starts from a bet about those venues. The coworking spaces, hubs and events where professionals already meet would pay for a networking layer their members actually use: a check-in, a live view of who is in the room, and analytics on what their community does. That bet turns every partner venue into a distribution channel instead of an advertising cost.
The idea underneath is older than software: people trust the ritual of handing over a card, so Cardixx keeps the object and the gesture and makes both digital and permanent. The card stays a card. It just stops getting lost.
67% of coworking members and event attendees come
primarily to network.
The Calls That Shaped It
OUTPUTA finished core beat a wide beta
Two whole product lanes were designed early and pulled out of launch scope. Thirteen months bought a complete consumer and hub experience instead of a wide, half-finished beta. What was cut is designed, sequenced and waiting on the roadmap
MONETIZATIONConsumers pay once, venues subscribe
Cardixx went to market free for professionals, an aggressive entry built to win the user base before monetizing it. When a professional does pay, it is a single one-time license, so the renewal decision that kills consumer tools never happens. Recurring revenue lives on the venue side, where the budget is
DISTRIBUTIONHubs before ads
Launch ran through five partner venues in Vienna and İzmir instead of paid consumer acquisition. Each hub brings its own members and its own daily traffic, so every partnership compounds. The venues are the marketing channel and the customer at the same time.
A Card You Can Hand Over
Cardixx makes a real business card, front and back, that turns in your hand in 3D, a quiet nod to the Rolodex it replaces, and prints on any printer when paper is still the etiquette.
It digitizes the paper cards you receive, keeps every card you carry in one wallet, and updates everywhere the moment you change a title, a number or a company. Templates, themes and a live preview take a finished card from zero to done in under a minute. The whole flow is designed to feel like a personal object, not a form.
Walk In, See the Room
Check in at a partner venue and Cardixx shows you the room: the professionals checked in around you, each with a stated networking intent: hiring, investing, looking for a co-founder, open to clients. Requests flow both ways, a chat opens when both sides agree, and the card is handed over inside the conversation with its context attached. Every exchange stays with its story, and exchange analytics show what a network is actually doing rather than what it claims.
The Hub Management Layer
Behind the app, hubs run memberships, events and visitor analytics on management systems I designed and coded myself. A venue applies from the app in about two minutes and goes live in under five, with its amenities, photos and community details in place. Each hub's public page is found on Google by professionals looking for places to network, so the network markets itself while the hub runs the room.
One Platform,
Three Customers
Cardixx serves three customers from one core. A professional carries the card, a hub runs its community, an event organizer turns a guest list into a network. Each side makes the platform more valuable for the other two.
The Professional
Goal: Turn event conversations into contacts that survive.
The card, the check-in and the analytics travel in one app, free at the door. A single one-time license unlocks everything for life. No subscription, no renewal decision.
Hub Operator
Goal: Prove member value beyond desks and coffee.
Cardixx turns a venue into a verified networking hub with its own public page. Members see the community, the community sees the venue. One monthly subscription covers all of it.
Event Organizer
Goal: Turn
attendee lists into
live networks.
Attendees check in to an event the same way they check in to a hub, and they start connecting while the event is still running. Cardixx is opening this side now for event organizers. It is a third customer on the same platform, not a second product.
The Brand Behind the Card
A business card is a personal object, so Cardixx could not feel like enterprise software.
The identity is calm, premium and personal, closer to a well-made card than to a dashboard. I created it from scratch: the mark, the wordmark, the color system, the typography and the motion language.
Hundreds of designed screens ship consistently across the consumer app, the hub tools and marketing, because they all draw from one design system.
Thirteen Months,
One System
Cardixx reached a team of twenty across engineering, design, marketing and sales, with a dedicated CTO and a mix of in-house and outsourced development. My seat is product and everything the customer sees: architecture, design direction, monetization, marketing output and the SEO program. Hundreds of screens, every flow and every card face came from my hands, version after version, across thirteen months.
Thirteen months from first concept to two countries. The next case on this system is already in build.
