Pros
I genuinely wake up excited to come into work every morning. This is the most transparent leadership team I've ever worked for, which is especially important when I'm personally and financially invested in the company. The leadership team has also put together an amazing workforce. I felt like I was a veteran after only a month, because of our onboarding process and how welcoming everybody was. I've also never experience a more inclusive work culture. Diverse is one thing, inclusive is a completely different task that Welkin has managed to handle very well. Very impressive benefits, especially for a younger company.
Cons
Haven't come across any yet, but I've only been here ~5 months as of June '18. Will update both towards the end of FY '18.
