Mark, sad to hear about Trevolta. All the best for the future.

Maybe there was a pivot in there somewhere? Though as we know here in SA you often do not have enough time.

i.e We (2 co-founders) raised $<10,000 for chowhub as you know,ran for over 9 months. Just paying the rent and feeding your family becomes a massive stress, especially if you do not have a safety net of rich parents/family.

Do not focus on external reasons for failure, introspect and figure out why and what YOU did wrong or could have done better. This is how you learn, look for contradictions in your thinking this is where insights come from.
