Startup Investments

Are there any platforms offering startup investments for small ticket size?

I used to invest in cryptos using wazix. But they stopped taking investment directly from bank account so switched to Coinswitch recently. Is it safe to invest using it? Thoughts. I am investing 3% of my salary every month.

My Gen X cousin and I were discussing our investment approaches. I told him about how most of us in my generation and peer groups choose to park bulk of our corpus in MFs, smallcases and some stocks. He laughed and ridiculed it out - stocks are the best way, why can't we do what the fund managers do. Just follow couple of good stock market apps that he mentioned above, do fundamentals of your own and invest away. Had long healthy debate, few strong pegs and agreed to disagree. To each their own, as long as we keep investing. But I never heard of these apps before? Is anyone here familiar using these apps and their services? Any insights you can share?

I was looking into ETmoney, is that a good app? And is ETmoney genius a good thing to buy? If not what app i should use?

Is there any way in which I can invest in an early stage promising startup? Think of it as a medium term investment

Got to know from someone that ppl invest amount in this range & get return on sales basis instead of the equity.
