Recent surveys indicate that 66% of UK Millennials are spontaneous enough to book a flight departing within 72 hours and 83% of the same group arewilling to change their schedule if they find a flight to a cool destination under £50. SpeediFly exploits this emerging trend for impulsive decision-making to turn itself into the ultimate catalyst for spontaneous travel for Millennials. The current problem on the market is that booking travel is an impersonal and price-centric lonely process. None of the old-fashioned travel platforms make proper use of data analytics for recommendation purposes. All you see on such platforms is “cheap”, "low-cost”, “discounted”, “limited-time” deals – it is all about the price and nothing about the experience itself. In addition, travel platforms are not social, making it hard for young people to organize group trips as they are now used to doing with Uber or Airbnb. SpeediFly is a direct response to this problem. By asking users about their interests and leveraging data from social media, SpeediFly makes people-centric and personalized last-minute travel recommendations to individuals and groups of people. SpeediFly lets users invite their Facebook friends, build in-app travel communities, invite others to specific trips, start group bookings and split fares at the end, just like on Uber. By tracking users' in-app activities, our system is capable of predicting what they are likely to book. This allows SpeediFly to make customized recommendations based on user behavior instead of simply trying to sell the cheapest available flights. | $206K | Seed | Jun 13, 2016 | | | BudgetBakers.com | BudgetBakers.com is a growing Prague-based startup, focused on keeping your budget low and helping you learn how to manage your money.
