Everybody fails at many things multiple times in their lives. Just try to manage failure gracefully and get things in order before trying again.
I have an honest but blunt question: how enticing is the idea of hiring a non-tech founder of a startup that failed only two years in and at best raised only 500k in funding?
"I led the team to ramen profitability and we had to raise only $500K in our two year of survival. We grew from $10K MRR to $100K MRR in 16 months. Unfortunately, we missed the target for our next fundraising round.
I heard you are talking to Saint-Gobain (or insert some big MNC) and I have done similar studies in their cement sustainability approach. Do you wanna talk more and see if I can help you fill in some blanks."
Now, I would or any founder love to talk more with that person.
