Impala's take on their challenges in 2021

Ben Stephenson headshot
Ben Stephenson
Founder and CEO

We're adding hundreds of hotels every month at Impala and are excited for that to become tens of thousands in 2021, backed by an every growing, extremely talented team of Impalans. We'll be making even more significant steps in 2021 towards our vision to make every travel experience perfect, by enabling innovation.

Our take on Impala

Steph headshot
Steph
Company Specialist

Impala wants to be as simple as Stripe or Twilio but for hotels. With a few lines of code, any developer should be able to get started with Impala before diving deeper.

Hotels use Property Management Systems to manage rooms, room types, extras, pricing, taxes etc. These systems are old, and providers to hotels need a load of integrations to connect to all the different hotel systems to get the data they need. Impala wants to make this easier by building a standardised API for anyone building services on top of hotel systems.

They're also building a direct booking API. Right now, many hotels manually upload booking data to websites like Booking.com, or use a middle-man to do this. Their API could cut out all of that and the commissions to middle-men along the way.

The panel's take on Impala

Saul Klein
Co-founder and Partner at LocalGlobe

Impala is building the future rails of the hotel industry - a vast but architecturally archaic market. They’re creating a new API enabled connective tissue that sits across the fragmented hotel Property Management Systems, by doing this Impala can be the single point of integration to this massive industry. By democratising access to hotel’s core booking systems, Impala could unlock the next wave of hotel innovation, just as Plaid has done in financial services.
