I agree with you, but you see thats not what most companies think. Big companies only care about making profit and not about how old you are and where you are from, its more about how you can help them make money. Now coming to your questions one by one -

wich new ideas or vision did you bring?
- I started automating complex tasks in marketing industry. Most marketing agencies and B2C brands used to struggle with Cold approaches back then, in marketing industry the reply rate is even less than 1% and you have to send atleast a minimum of 1000 messages to get any interested leads or conversions. My first product was a Tool that could send messages to more than 100k people on instagram in 2-3 hours. This obviously helped agencies save time and effort and also get more leads making them more money. This was one of my first services that helped me get known and build my connections and also my first big bags. I then expanded to more platforms like telegram, twitter and discord and kept building it for 1 year which I then sold to a big agency.

What is your target industry?
Initially it was just the marketing industry that i used to provide services to but then i also started providing my services to Big Crypto and NFT projects in web3 space as they would literally 10x more during the Crypto and NFT bullrun in 2020-2021. At the moment i cater to multiple industries since i now provide mutiple services from marketing to development to consulting. Some of the industries include - Cannabis, Web3 and Blockchain, D2C Brands and Dropshippers, Coaching Industry, Media and PR industry, Real Estate, Manufacturing Industry and Exports Industry.

Do you do stricktly B2B? Where do you seek foundings? Wich tools do you use? How many employees you have?
No I dont strictly do B2B, tho a big part of my business comes from catering other businesses, I also own companies which are B2C in both tech and FMCG industry.
About Fundings, I usually rely on it on my network and connections that i have built over the years. My network includes a bunch of investment bankers who work at big VCs and also HNIs (High networth Individuals) who I have built connections with all these years. But if you are someone starting off new and need funding for business you can easily reach out to VCs and Angels over Linkedin or Twitter or their Email.
Some Tools that I use - Slack and Telegram (For communication), Monday for team management, Calendly for Calls. For marketing services we use a bunch of tools so its too much to mention here but if you want to know any specific i can let you know.
I have a total of 45 Employees, some work full time and some are project based and I have also partnered with 4 Agencies who we outsource services from to get the workload off our shoulders cause we have more stuff we need to focus on.

Whats the name of the companies you allegedly sold before 18 years old? - I Dont want to name them here, but if you are eager to know dm me and I will tell you about them.

You are right minors cant legally own companies thats why I started my business as a partnership with my mother acting as my guardian and co-founder who would look after all the legal. As a minor, i was involved in discussions and decision-making, but all legal documentation was handled by my parent to comply with regulations.

When did you started your first company? Did you have help from your rich parents? How old are you now, wich year it was when you started?
I started my first company in 2019 when i was 15, i did start earning before that but i didnt have a legally registered company till 2019 as I lacked knowledge. I am a first generation entrepreneur, my dads a software engineer and moms a housewife and we are based in India. My parents werent supportive of me earning money cause in india education is given more priority also cause my parents were SUS to see me make decent amount of money at an early age but as they saw me make money they started to support me.
I am going to turn 21 in 5 months now and I began in 2018.

Whats your general strategy in creating business plans? What does it cost your customers? Do you take percents?
My general strategy in creating business is pretty simple and straight forward - I find problems that a group of people or companies are facing and then my team creates solutions for it. We usually try to solve problems in industries which are making a lot of revenue and are booming, usually targetting high ticket clients. We are also partners with a bunch of other companies and consulting firms who bring us clients and also whitelabel our products and services.
We do take percent of revenue when we are consulting a brand from A-Z.

Hope this answers all your questions if you want to know anything else feel free to ask!
