Workplace and culture
Hey there! 👋 We’re GOLD AVENUE, and we’re here to shake up the world of precious metal investment. If you think gold is just an old and dusty metal, well, our goal is to prove you wrong.
Do most precious metals online resellers you know have a 1990’s looking website, a long list of hard-to-understand products, somewhat cheap and obscure prices, and no solution to store or resell your gold? Well, we have the opposite:
- A UX-friendly website: making it as simple as buying socks (are socks easy to buy?)
- a brand new mobile app: putting gold investment at your fingertips
- Clean and crisp design: we like it easy on the eye
- Transparent and simple pricing: because we hate complexity, don’t you?
- The best all-in-one solution on the market: or should we say… in Europe?
- A multilingual and expert customer service: did we say we like to make things simple?
- Enjoyable educational content: helping you understand what makes gold tick
That’s because we’re on a mission to do things different, and make gold investment accessible to everyone.
Why you’ll love working with us:
- 💥 To make an impact: Your work will directly help people across Europe invest smarter and feel more secure about their future.
- 🌱 To grow with us: We’re all about learning and growing together. Whether you’re a newbie or a pro, there’s always room to level up here.
- 🌴 To send you great vibes: We believe work should be fun and fulfilling. Join a team that’s friendly, supportive, and ready to celebrate every win, big or small.
- 😎 To enjoy a flexible work life: Need to work from home sometimes? No problem. We value balance and understand life’s demands.
Why we love working here ❤️

In other words, we care about being flexible, caring, and human with our team, and we welcome anyone who brings a unique perspective, some cool ideas and skills, and most importantly a sense of ownership and hard work to accomplish great things together!
Want more perks? Well, we’ve got more! Office in Geneva’s old town with a shaded courtyard for summer lunches, showers for those who like a run around the lake, ping-pong table to show your skills, free snacks, coffee, tea, fruits, in the kitchen, etc. And because it’s not only about work, we also like to organize a yearly summer company retreat to enjoy a few days all together in a nice location, and of course company parties and afterworks throughout the year.
Who we are? We’re a diverse crew with a shared passion for making precious metals accessible to everyone. We’re proud to be leaders in the market, but we’re even prouder of our awesome team.
