❤️ Well Being, compensation and how we behave when no one is watching?

We care about your well-being. Along with excellent health insurance, we offer flexibility to work how you want to. We push for physical well-being and in addition to internal health sessions, you get a complimentary annual gym membership.

We assign dedicated work hours exclusively to learning & development initiatives. We respect your weekends and in terms of work hours, we believe in deliverables over anything else. We regularly host team-building sessions, off-sites and encourage discussions around mental well-being and physical well-being over everything else. Most importantly, when our chips are down, we behave the way a family would.

We admire talent and believe in rewarding people for their input. We understand that compensation is an important factor. Our compensation will be respectful to your situation, and the whole process will be transparent from the very minute we speak to you.

Most of us have grown up in a meritocratic culture where actions speak louder. We grew up saying yes to a lot of things outside of our comfort zone and we want to maintain the same without any compromise. When actions speak, we love to celebrate and amplify bold moves. We don’t have answers to a lot of questions and when we falter, we will acknowledge our missteps. There are no closed doors in the way we work. At the end of the day, we are human beings and we will ensure that you can proudly call Crunchit your home.

🍰 What gives you brownie points?

You demonstrate learnability. The founders have spent their years building things mostly independently and at times relying on the collective hive mind of peers. If you are willing to learn and dare to say yes to things that lie out of your comfort zone, you’ll love the growth and transformation.
