Indian VC's don't really have the same appetite for deep tech as compared to America/Europe. R&D within Indian Enterprises is significantly less as compared to its peers.

From what I know, its partially because of how taxation structures incentivize research as R&D tax breaks or similar don't particularly exist in India

All of this makes founders more likely to move abroad where such research is more valued which makes even less Indian deep tech startups and successes exist. This creates a vicious cycle.

I would also consider that Indian VC scene as compared to America undervalues quite decently even for B2B or even supposing identical companies and even then, Sequoia and some other American VC firms are still the most valued and I feel as if that given their expertise and contacts (other companies that the VC's have invested in being in America), there would be a slight push towards Europe/America in general. Another argument could very well be that in India CS engineer labour costs much less which is honestly some of the largest expertise for any company.

Though Indian VC scene is thriving and Bangalore is interesting but still Silicon valley is different.

There was a blog post which talked about VC dynamics and VC's value your product not on how much the real value they really see in the project is but rather on how much money you would require. So ironically, projects which require larger budgets/funds for researching, larger salaries to work would then have larger valuations.

Rocketry is tightly controlled by ITAR, so mobility is lower than you'd expect for a high value field.

My cousin is an aerospace engineer and works in ISRO (Indian space research organization), its impressive what they are doing but I'd like to chime in on a few things.

I am unsure about private salaries but in govt. jobs, because it follows a rigid structure, the salary is still lower than what you might expect and is around the mark of 20-25 thousand dollars per year. It's similar to administrative services or depending on the position, equal to teachers/professors .

I have heard my cousin say that its hard for people to move outside because for example SpaceX/NASA couldn't hire non-American person because of laws and regulations due to security purposes.

From what I know, my cousin actually got some job offers when he had gone to give a speech recently from Management companies

20-25k$ in India isn't bad but strictly speaking, Computer science earns comparable in India at the same level.

The value of the job is mostly in govt rather than private and the benefit of it is that the work is much less stressful rather than private companies stress and just like how NASA has some prestige attached to it in America, same way goes for ISRO in India.

> rocket engineers/scientists are in high demand with lots of likely sponsors for immigration

I wouldn't be too sure about the immigration part, when even a software engineer hire for a defence/defence adjacent job requires jumping through a number of bureaucratic hoops of security clearances. Even the companies with deep pockets don't always get the best people in the world -- they just get the best people that HR can actually hire.
