What do you think about a platform similar to clarity for the travel vertical ?

That's a much more complicated question than it appears to be, as there are multiple sources which will get you some of the inventory, but nothing which will get you all of the inventory. If you look at an OTA, they are pulling from typical sources like SABRE or Amadeus, but also from what is in effect their own inventory, where hotels are either going in via an extranet or there's some kind of direct-connect to the system the hotel is operating on (which could be one of many, including none at all). In fact, some of the OTA's make that proprietary inventory available too, via an API and on a commissionable sales basis. There's just no one-size-fits-all access point - especially when you consider that worldwide the hotel business is actually very un-aggregated with something like 80% of all hotel room capacity operated independently (that is to say, not branded or part of a chain like Starwood, Accor, IHG etc.). It's a big part of why OTA's have invested so heavily in technology to manage and distribute this type of inventory. It's not easily done as the technology used in the hospitality industry is often not great and it's unconsolidated to there's value and negotiating strength to be brought from consolidating it.

Several ways come to mind. Formulate your idea into one (or better all) of the following + you'll know by interest level if you have a winner. 1) My favorite. Start a Meetup Group (set the zipcode of group) to match the zipcode of a US city where most people originate travel to your target destination. For example, If your targeting running tours in Chang Mai Thailand, research what city people in US most travel from to visit Chang Mai. Then run Meetup events related to Thai Travel topics. 2) Package information about Thai Travel into a PDF + sell it via Facebook Ads. 3) Start a Kickstarter project. 4) Speak at existing Travel Meetups + other groups + related conferences about your idea.

Before you spend $ or time marketing your service / website, ensure that your brand itself is quite strong. For example, if your name or domain is awkward, ambiguous, or off-putting, then every dollar and hour you spend promoting your brand will work less efficiently in your favor than if you were spending the same amount of money and time marketing something more robust and attractive.
