Do your due diligence independently before joining this company, as their story may not line up or it can quickly change.
Nepotism is real across the entire company.
This company is a christian based organization, and atheists or those from diverse religious backgrounds may want to make that known right away to judge their opinions. Blessing god after a company meeting is normal, as are worship events at the actual office you do business in, which is extremely odd for start-up that need a range of experience and background to begin to succeed.
This company is funded by the CEO, and their book of business relies on the religious philanthropic connections, not through the independent value of their product, which is generally half baked and unusable without someone there helping you use it.
Don't expect to be integrated quickly into the company, as the beauracracy and red tape has people more worried about office poltics than they would about getting things done. Critical opinions will not be valued.
The company is not structured like a common software start-up -- instead it is a loose group of project teams working with a small number of clients to try to figure out what they want to build(still figuring that out)
