Most startups face similar decisions when getting started, especially regarding the platforms and tools for internal processes and back-office management. I'm interested in learning about the internal tool stacks other startups use or have used.

    - What group of tools did/do you use in your startup?
    - How many employees do these tools serve?
    - What gems of information or pain points did you discover along the way?
    - How would you approach this differently in your next startup?
