Do it now!

I don't know your life situation but there's no reason why you can't just continue to try and validate the idea by generating a few early leads and seeing what people are willing to pay before launching into your first project?

Now is the best time to make your dreams come true! Some, as the say in Brazil, may have been "born in a golden crib", others are counting on a rich inheritance, still many have married in to wealth.

For the rest of us, there has never been a better time to build and sell a tech startup. Valuations have gone up 10X since the first wave of tech acquisitions, barriers to entry have been vaporised and the playing field has been levelled, yet only those with the right mindset will succeed.

What you really want to ask yourself my friend is: are chatbot startups getting acquired? Who is buying chatbot startups? What kind of chatbot startups are they buying and why? Happy to help you with those questions.

As for the mindset, here's your north: http://RMentrepreneur.fyi.to/ElonMusk

That's a bad gamble imo. What exactly do you mean with validated????

Validated to me usually means pre-sales. Literally, their money in your bank account before you risk any of your hard earned money and precious time, then there is much less risk to you and the fact they are prepared to kickstart your development is a strong validation signal...

I would focus on who your customers are and where you see a business model developing. Start with something specific and get to market quickly. Test on live accounts and treat the early customers as partners.
