Its premise is to let travellers hold all the information they need for a trip – key documents (including Atol certificate), maps and weather.

Today, Bean says there are now more than 100 tour operator and travel agent customers in 15 countries. It continues to be trade-only, and is not available to independent travellers – only those booking with registered operators or agents.

Last month, however, new features were added to help travel businesses sell more holidays. And Bean says Travel Technology Europe (TTE) was the best time to launch these new functions.

“While the original idea behind Vamoos was to improve and declutter the travel experience, once the app is loaded on a user’s device, it’s crazy not to use it as a selling tool,” he explains. “And TTE was the perfect forum to introduce this game-changing functionality.”

One new tool is “Inspirations”, which will enable operators and agents to actually sell holidays. “It’s a natural fit for us,” says Bean. “We feel we can build even more value for our customers. Mobile is particularly good at delivering the right message at the right time, and then providing a trigger to buy – and we’ve built Inspirations to do exactly that”.

Inspirations allows operators to display their range of holidays to existing clients returning from a trip, as well as new prospects who prefer to browse in an app environment. This helps with repeat bookings and brings new business from clients who have downloaded the app, which operators over-brand. It also gives clients a simple, one-tap experience to book their next holiday.

“It’s that mobile trigger that’s really proving powerful,” Bean says. “We live in an immediate world, and travel is no different – people want to book a holiday in an instant, wherever they are.” The update is a free addition to Vamoos clients, with Bean stating that there is no commission charge.

He tells me that since the launch, he has remained true to this ethos of listening to clients’ wishes and regularly organising events to roll out and test new features. Other app updates include a notification centre, which enables operators to automatically send timed and GPS-triggered notifications – for example, a client can receive a welcome message to their mobile when they are one kilometre from their lodge or hotel.

An “Intelligent Itinerary” builder has also been factored in, allowing operators to showcase their clients’ trips in more depth, with users able to have a dedicated page including customised image, accommodation details, maps and extra information.

Recently, this was adopted by Aito for its November overseas conference in Jordan. Elsewhere, a new client journal lets clients take pictures and add comments directly to the app. Photos and discussions can also be shared directly to social media. The live journal and diary space is one feature that appeals to many start-ups as tech companies look to provide user-friendly ways for travellers to document holidays.

The future is clearly looking bright for Vamoos, which has just opened new offices in London’s Paddington. Customers to date include Exodus, Journey Latin America, Black Tomato, Audley Travel, Original Travel, Transindus and Natural World Safaris, among others, while recent client wins in the past few months include Bespoke Latin America, WST Travel, Sportif International, ABC Leisure, Action Challenge, Africa Odyssey, Sun-Hat Villas, McKinlay Kidd and Tribes Travel.

Bean claims operators have embraced Vamoos because of the simplicity of its design, and because the back-end process “is so easy to manage”. “Our API means that operators can connect Vamoos apps directly to their reservation or booking systems, so that they populate all the client details and documents automatically,” he adds.
