How Three Competitors Came Together To Create A Multi-Million Euro Startup

Reading progress

Three competing short-term rental business owners met at a round-table to discuss how they could survive the imminent rise of Airbnb. They came up with a software solution. Now, Rentals United helps property managers in 160 countries to gain time and make more bookings. Oh, and they’re a preferred partner of Airbnb… how’s that for full circle.  

This is the story of how three entrepreneurs went from directly competing with each other to launching a company together and securing $4.2 million dollars in VC funding to help build the future of the vacation rental industry. They created Rentals United based on a simple idea: create a channel management software that is easy to use and accessible to every vacation rental professional.

Here’s their story, from the dark cellar office to the successful start-up with almost 100 employees in 3 locations.

Hungry entrepreneurs

James and Vanessa previously created a vacation rental agency in Rome with literally every penny they had in their pockets. It was a make or break situation: make the pennies work or pack their bags, go back to London and find a run of the mill job. Luckily they were making a profit from day 1 and were quite successful for the first few years.

Now simultaneously in Warsaw there was Emil, who started as an IT guy at a vacation rental agency and was promoted in 4 years to no less than CEO, heading a 90 people-strong company at age 24. Then bad luck struck and he spent 2 years in hospital, thinking about what’s next.

If you can’t win, come together

Meanwhile, Airbnb was receiving large investments and turning the industry on its head, and consequently, the mid-size short-term companies were struggling to compete with their marketing budgets.

So when Emil was discharged from the hospital, he decided to contact competitors to “come together at a round-table to discuss how, as small- to medium-sized agencies, we will survive the giants”. He sent invites one-by-one and decided that when he had 4 interested he would stop. James and Vanessa were number 3.

At the round table, a plan was drawn. Competitor one, two and four soon vanished. Emil, James and Vanessa remained. Rentals United was born.

Money talks

The first few months of Rentals United was spent in a dark cellar (literally!) and with a hoard of interns, cold-calling property managers around the world. When a semblance of traction was detected, a first angel investor was found who funded a new, slightly less-dark office. Fast-forward 3 years, and we are writing this article from our large and shiny office in Barcelona having just secured $4,2M in VC investment.

Build on partnerships

Our story is one of a successful partnership born of collaboration and forward-thought, and our origins still drive us today. We partner with over 100 tech businesses, many of whom are only a few degrees off from being considered competitors. We believe that partnering with a diverse group of companies can only help our customers become more successful.

As a result, we have expanded on the channel management business and now offer a growing family of third-party services that work together with Rentals United to improve a property manager’s workflow.

From setting the right price via yield management software to automatically sending timely messages to guests via guest communication platforms and, even booking the cleaner via housekeeping software, the Rentals United marketplace is growing month by month.

Frequently asked questions

Rentals United is a vacation rental channel manager built for short-term rental hosts and property managers. Rather than replacing your property management system, it plugs directly into it, syncing your listings in real time across 90+ booking channels, including Airbnb, Vrbo, Booking.com, and Expedia, Homes & Villas By Marriott Bonvoy, all from one dashboard. With AI-powered analytics, and guest communication tools built in, it automates distribution and helps you grow bookings without adding complexity to your existing workflow.

 

A vacation rental channel manager — sometimes called a short term rental channel manager — is software that connects your listings to multiple booking platforms like Airbnb, Vrbo, and Booking.com, keeping rates, availability, and reservations in sync so you never risk a double booking. If you’re updating calendars manually, missing promotion opportunities, or leaving bookings on the table because a listing isn’t optimized, this is exactly the problem it solves. A revenue-first channel manager like Rentals United goes further, using AI-driven insights and multi-rate pricing to help you win more bookings on the channels you already use — properties using multi-rate pricing have earned up to 3x more revenue

No minimum size required. As a channel manager for vacation rentals of every size, Rentals United works for hosts managing a single property up to enterprise portfolios — it’s part of a network of 403,000+ properties connected worldwide. Whether you connect directly through Rentals United, through your existing PMS, or via our channel manager API, the platform scales with you, so you can add channels, features, and properties as you grow without switching systems.

Getting started is straightforward, whether you connect directly, through your existing PMS, or via API. After signing up, Rentals United’s onboarding specialists personally import your listings, connect your booking channels, and recommend the right channel mix for your portfolio.

Every Rentals United account comes with a dedicated Account Manager and access to channel experts who know both the platform and the short-term rental industry — not just generic technical support. Beyond one-to-one guidance on optimizing your channel mix, pricing, and promotions, you’ll have access to Rentals United’s knowledge base, API documentation, and ongoing performance reviews, so you’re never troubleshooting alone. Enterprise clients are also backed by SOC II-compliant security and operational reliability.

Every integration, whether direct, through your PMS, or via our channel manager API, follows the same security protocols, so your listings, rates, and reservations stay protected no matter how you connect.
