My first thought is a chain of non-profit grocery stores.

The Foundation for the collection of antimatter.

Fair trade, recycled and all natural store. I had a business called Green Lady but sold wholesale to others-I'd have my own shop this time.

I would start a medical marijuana growing and distribution company

I know they say never make your hobby your job, but I still think the right answer here is "pornographer."

A franchise of free grocery stores managed by low-income people.

I would like to turn my back yard into a community garden. I just don't have the funds and energy to clear the land and upkeep the garden.

Video game development

I would start a business that involves selling items I love to create. A business that has items people will want, but only if they are unique and special. This way I can work in what I love and the money coming in is something good too.Click on [tastefulspace.com]

A brewery. But i'd need a million...

Start a zero cost university of science for gifted young people who would otherwise not have an opportunity for advanced study. One of my lifelong dreams.

A low cost chain of universities for people in third world countries who could not otherwise afford to continue their education.

I'd open a hair salon catering to curly hair. It's hard to find stylists who know how to cut my hair. Most of the time I have to fix my cut after a salon trip.

I would build a handicapable/neurodiverse arena to host not only Special Olympic and sporting events, but big named entertainment concerts for the public as well. Inside the building there would be offices of occupational, speech and language, physical, individual and family therapy, with funded arts and crafts activities, availability for respite to the family of care givers (from infancy to elders). Vocational opportunities for all, great way to volunteer hours, great way for local companies to participate and advertise. Medical staff on site. State of the art handicapable playground on the grounds alongside a an indoor/outdoor therapeutic and swimming pool. Sponsors from Autism to Alzheimer associations.

I would call it the O’rena. A name an Autistic client called me. Dream big!

I'd like a little restaurant. Nothing fancy, just a little burger joint.

I'd start a worker-owned co-op to rival the world-sucking Amazon.

Not a business, as it wouldn't make money, but animal shelters, both domesticated and wildlife.

Oooo, this is a tough one. I think a shelter for homeless LGBT+ youth. It's not really a "business" but I can use this money however I want. Sustaining it would be another thing though, but that isn't what this question is about!

Open an organic movie theater

-Sustainable Agro Business
Considering climate change, populations growth, an area around the world needing more research and funding, more farmers around the world need new and alternative ways of farming.

An american style Malt Shop that sells nothing but milkshakes and smoothies.

a music studio. will find musicians for a band and record my music. the album name "Puerto Rican Hopes, Cuban Fantasies and American Dreams".

I would buy a warehouse. Turn half of it into a flat pack skatepark and hold events. E.g. Gigs and charity events. The skatepark would be open to anyone and all profits after overheads would be donated to causes I deem to be worthy.

Is start a little woodworking business, making custom furniture.

I would open a chain of old folks homes geared specifically for dorks, and do it up right. Top of the line medical care combined with wings that look like Gondor, the old Battlestar Galactica set, that shit would be gold. If anyone steals my idea, hook me up with a room!
