About Janno

********** THE STORY **********

Hong Kong, August 2018 - after a week of mentoring Chinese startups, I was talking to this Brazilian guy I had just recently met, that maybe instead of just mentoring the startups, we could try the "hands-on approach". I mean: to find a great team with an idea we like, build a working product, bring it to market, and see what happens...

********** THE PLAN **********

1. Find a startup with great people, solid business case and no tech/product team.
2. Join the team and build the MVP with 2-4 weeks.
3. Launch the product and get traction.
4. Get an investment and build a team.
5. Scale it up and see what happens

********** THE SKILLSET **********

We can build an amazing product from 0 to 100 in a heartbeat.

I'm a professional software engineer (ex-Skype) and the Brazilian guy is a professional UI/UX designer.

Together we have 35+ years combined product development experience and close to 100 startups we have mentored.

********** THE STARTUP **********

If you are an early stage startup, with business and marketing people but no techies, you would be our perfect fit.

We're looking to join a team, where everyone brings something to the table that others don't have.

********** THE REQUIREMENTS **********

First, you need to be committed to this. I mean really committed. Work with your startup the whole day and think about it the whole night.

Second, you need to be experienced in what you're doing. If this is your first startup and you're really not sure about anything, you should have significant traction or convince us with your super-motivated personality.

********** THE ADVENTURE **********

Well, this chapter is for you to fill.
Send me a message and let's see what you got.
