Diversity & Inclusion 🌍

We want everyone at Puzzel to be their true, authentic selves at work irrespective of nationality, race, ethnicity, religion, sexual orientation, gender identity, physical ability, age, or economic background.

Whilst we are proud to already have a diverse workforce from across the globe, we are aware that things could always be improved – for example, we currently have a ratio of female 26:74 male employees, which whilst not uncommon for the tech industry (average in SaaS is 26% female), it’s far from ideal. So, what are we doing to improve this?

• Our Global Leadership Team (C-suite) has shifted from 100% male to 50 male: 50 female in the past 18 months.

• We have increased our % of female hires from 23.6% in 2021 to 38.5% in 2023.

• We are partnering with the likes of Flexa, who have significantly higher-than-average talent pools of candidates from diverse backgrounds.

• We are working with State Employment initiatives in Norway and Sweden to bring candidates through internship/apprenticeship routes and are investigating similar initiatives in the UK and Bulgaria.

• By raising awareness and transparency, we are hoping to further attract a diverse workforce.

We are continuously striving to foster an inclusive and diverse environment, where everyone is celebrated for who they are. If there is anything we can do to support you in the interview process, or beyond, please let us know.
