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 are operating out of Central Indiranagar, Bangalore. We are firm believers in "when we sit together on a table, we move mountains". So you will be required to come to our office [WFO], which we have designed with a lot of love and affection :)
