Zilarent was built to run Blue Diamond Vacations, our founder's own rental car company

Now hosts and rental car companies across the US get their own booking site and the dashboard behind it. We do the setup for you, then answer your questions as the business grows.

The principles we run Zilarent by

How we work with you

  • Go direct

    Grow bookings under your own name and depend less on Turo.

  • Run it your way

    You decide how your business runs. If you need a feature we don't have, tell us, and we'll talk about building it.

  • Here after launch

    We stay with you once you're live, and we help you grow.

How we build the software

  • Always improving

    We keep building Zilarent, and we look at new tools that could make it better.

  • Focused

    We build for independent rental car businesses and nothing else.

  • Quick to adapt

    We move fast and change course when customers or the market show us a better way.

We help with insurance, branding, your Google profile, and growing your rental business

  • Insurance

    We introduce you to insurance providers we work with.

    Zilarent is not an insurer.

    Car rental business insurance

  • Branding

    We build your site in your brand, or help you create a simple one: colors, copy, and a logo.

  • Your Google profile

    We walk you through setting up your Google Business Profile.

  • Growing your business

    Call us any time for advice on growing your rental business.

Isaiah started on Turo, then added direct bookings

  1. Turo
  2. Direct bookings
  3. Zilarent

I run Blue Diamond Vacations, a rental car company on Oʻahu. Like a lot of the hosts I talk to, I started on Turo.

As the business grew, I wanted renters to book with Blue Diamond directly, under our own name. So I built our own booking site. That system became Zilarent.

I still run Blue Diamond today, with direct bookings beside Turo.

  • Blue Diamond Vacations runs 21 active rental cars as of October 2026.
  • It is rated 5 stars from 631 reviews on Google, as of October 2026.

On the call, I'll look at how you rent today, then walk you through the booking site and dashboard.

No matter how small or large your fleet, we'll provide you tailored support each step of the way to help grow your business.

“From the beginning of Blue Diamond, I focused on the highest quality customer experience. That priority led to strong customer relationships and many repeat customers that helped grow our direct bookings.”
