Blinq is the AI contacts app for people who meet people.

We're on a mission to unlock the world's relationship potential. So much of what's possible in the world is locked inside relationships that never quite happen. A missed conversation, a forgotten follow-up, the right person at the wrong time. We're building so those chances aren't left to chance.

What started as the world's #1 digital business card is now used by 4 million professionals and at 93% of the Fortune 500. We've raised $45m+ from Blackbird, Square Peg, HubSpot Ventures, and Touring Capital.

What We Offer

~1 min read

✓You want to be part of an AI-native company at an inflection point. Big enough to have real momentum, customers, and resources. Small enough that the work you do shapes where it goes from here.

✓You want to do the best work of your life alongside people doing the same. We hold an unusually high bar for talent and we hire people who treat that as a feature, not a threat.

✓You want to build something globally ambitious from a part of the world that doesn't always think this big. Our team is in Sydney, Melbourne, San Francisco, and New York, and we're betting that the next category-defining company in our space comes from Australia.

✓You want to work in person, on purpose. Three days a week in the office, two wherever works for you. Creative energy and momentum compound face to face.

We've all joined Blinq to find out how good we really are. That shows up in how we work:

We are professional optimists. We think what's possible first and let constraints come second.
We hold an insanely high talent bar. A players only.
We are obsessed with craft. The details are the thing, not the polish on top of it.
We are truth obsessed. We say what's true even when it's uncomfortable, and we have the courage to pursue contrarian but correct bets.
We do more with less. Calculated frugality and beautiful simplicity guide how we build.
We are all here to genuinely do our life's best work.

Our engineering team is the engine behind Blinq’s success. We’re building tools that make sharing who you are instant and human. Every line of code, every release, and every experiment is focused on driving meaningful impact. If you thrive on solving complex, high-impact problems with a tight-knit team, you’ll feel right at home here.
