Diversity & Inclusion at Impala

Tilly Firth headshot
Tilly Firth
Head of People and Talent
  • We went beyond the usual standards on the D&I front, and we created our own D&I deck. This contains most of our D&I initiatives. This was created to hold us accountable, to further embed D&I into our cultural identity, to share thoughts and ideas to other companies, and to encourage more diverse ranges of candidates to apply to Impala - as anyone from any background would hopefully be able to see that they would be included at Impala. View the deck at shorturl.at/cmJU3
  • We've partnered with ReachOut in their Level Up program, to support people from disadvantaged or underrepresented backgrounds.
  • We run 'Inclusion 1:1s' each quarter, and ensure we maintain a virtuous cycle of inclusion
  • We've carefully crafted flexible policies, as we think these create a more inclusive environment. Check out our Flexa page for more https://flexa.careers/companies/5fbbb02b9001f90008abb85d
  • We also embed equity measures in hiring - beyond just 'equality' measures - we view diversity measures in hiring as a series of processes that should be coherent and congruent. Examples include: 1) A higher referral payout for referrals from underrepresented backgrounds, 2) More time and resources dedicated to sourcing candidates from underrepresented backgrounds, and 3) Adjusting the minimum requirements and reviewing data beyond the CV to make sure we're not excluding people
  • We researched and addressed some of the main reasons why Women and Minority Ethnic candidates may typically be deterred from applying to a startup, and proactively shared thought pieces on the topic
  • We look to focus our efforts and resources on grassroots initiatives as well as internal initiatives. We care more about there being a fairer environment and industry and making it better for the future, rather than just creating a more diverse team

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.

Otta's take on Impala

Xav Kearney headshot
Xav Kearney
CTO of Otta

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 headshot
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.
