Céline Frey, CEO

"We are proud to be able to support our clients at a key stage in their lives: securing accommodation. We have developed a unique solution enabling tenants to upgrade their rental guarantee to fit their needs. Our rental guarantees offer tenants great flexibility with or without a bank deposit while providing our partners in the rental industry with maximum security.

For over twelve years, Firstcaution has built up a relationship of trust with professionals in the real estate sector. We continue to innovate in order to provide them with greater flexibility and responsiveness when issuing and releasing rental guarantees. The entire Firstcaution team is committed to improving the quality of our day-to-day services. Recognition from our customers and partners is our reward, inspiring us to achieve more."

We have been issuing rental guarantees for twelve years and act as a bridge between tenants and property management companies or landlords.

What we do

We want to facilitate access to accommodation and support business growth. We are convinced that access to accommodation should not depend on tenants being able to block three months' rental guarantee in a bank account.

We offer simple and innovative solutions that meet the needs of tenants, property management companies, and landlords.
