How do you build a Big Tech Firm out of India?

This question has puzzled quite a few tech thinkers both in the government and the private sector.

Big Tech has significant representation from India, so why can't we figure out a way to merge these groups in a separate room and build a new firm?

Well, only if it were that easy.

On the face of it, United States offers quite a few advantages - largest economy, well developed markets, common language, big talent pool, strong intellectual property protections and an academia-industry connect that allowed companies like Alphabet to form.

India has covered ground on talent, economy and funding to some extent since the economic reforms yet the first big tech continues to elude us.

So let us break down what a typical big tech firm has -

1. A core business backed by humongous scale or deep intellectual property advantage that put it on the map :
Alphabet (Search)
Microsoft (Windows OS)
Amazon (Ecommerce)

2. Secondary businesses at scale built on the back of the core business that aid its scale and add to profitability :
Alphabet(Youtube, Android)
Microsoft(Azure, Office, Xbox)
Amazon(AWS, Amazon Ads)

3. High R&D Spend and bets on the future to maintain dominance either in-house or via acquisitions :
Alphabet(Waymo, Calico, Google Fiber)
Microsoft(Activision, Nuance, Linkedin!)
Amazon(Alexa, Twitch, Whole Foods, iRobot)

As of now, we are yet to build a digital product out of India that is globally dominant in its category especially one in the B2C Space.

Once some firm breaks through the first barrier, we can think about a big tech out of India.
This should happen within the next few decades considering the pace of technological process and the increasing complexity of firms operating in India.
