Pros

- A few people there are genuinely kind and doing their best. - The office is nice. - The staff is relatively diverse.

Cons

- The company preaches constantly about "culture" and "changing the world" when in reality they couldn't care less and regularly fire swathes of people to pad their bottom line or cover for mismanagement. - Management is largely incompetent, especially in the C-suite. They have little clue what's going on at any given time, make absurd asks they clearly don't understand, engage in shady/morally questionable practices, and regularly demonstrate how little they care for their employees despite all the fluff they say. The current CTO is especially egregious in that regard as one of the most uncaring, unthinking, unpleasant individuals I've ever met. - Playing politics is valued more than getting work done. All your accomplishments will mean absolutely nothing if you're not brown nosing the right people. - The company always has plenty of money for catered sushi lunches, truckloads of merch, guest yoga instructors, and an endless list of other frivolous nonsense, but when it comes to paying everyone fairly it's a nightmare uphill battle, they've even cut salaries later down the line (but not for the C-suite of course). - The HR team is kind to your face but very mean behind your back.

Pros

This is a company focused on expanding access to credit and economic opportunities. That’s a mission I feel good about supporting every day. The people are also amazing perhaps bc the company attracts people who want to do good in the world. The CEO and his vision for the company set the tone for both the mission and the culture. He is very focused on ensuring that the company is supporting holistic well being, and that women and minorities have a seat at the table.

Cons

It’s a smaller company so there is obviously less structure than larger companies, which can be a con for some, but for me it’s empowering.

Pros

Working with this company has been a truly energizing experience. It's a place where innovation isn't just a buzzword, it's embedded in the culture and reflected in the work every day. The team is composed of incredibly smart, motivated individuals who are not only experts in their respective fields but also deeply committed to pushing boundaries and delivering meaningful impact. What stands out most is the level of collaboration and intellectual rigor across the organization. Everyone is encouraged to think creatively, challenge assumptions, and contribute ideas, regardless of title or tenure. The leadership fosters a high-performance environment while remaining approachable and supportive.

Cons

I can't think of any at this point in time.
