First, why a Product studio? Placing multiple bets is better than investing all your time in one single project + no need for funding, no need to quit your job...Now, the recipe is simple: 
1/ All your projects should have almost identical components, example:
- Curated directory 
- Community portal 
- Deal pageExamples: 
A website who matches business owners with pre-vetted accountants + community for smb owners to discuss financial matters + finance related software deals.Key takeaway: Choose carefully your components, you will reuse them later on.2/ You need a tech stack, preferably a low-code stack to launch cheaper and faster.This usually is a mix of tools, for the example above, we would use Umso + bubble + airtable + zapier + Facebook groups.This the simplest form for me to give you some value on how to build a product studio. Now we run our own and partner with creators/entrepreneurs to launch products.If you have questions, want to launch a product together (like the example above), want advice on tech stack, etc...Email me mbm@btwinz.com
