Taming the TAM!
Assessing correct Total Addressable Market (TAM) leads to relatively right valuations and potential right sizing of IPOs!

Recently, Infosys co-founder N R Narayana Murty had some critical views on current venture capital/ funding scene in India. Murthy opined that some venture capitalists are giving undue importance to top line over the bottom-line revenues.
In some ways, this has also become a Ponzi scheme, because you know I am in series B…I sell my first deal at a profit, I get off and it is the series Z fellow that is left with the tin box. - Narayana Murty
Is VC investment a Ponzi Scheme?

NRN’s statement is true to a large extent and one of the reasons for that is the vicious cycle of wrong TAM, high valuations and overpriced IPOs. (I recollect him saying that he had affinity to communism initially and later embraced capitalism!) One of most common mistakes many early-stage startup founders make is calculating a TAM that’s not necessarily accurate or obtainable.
Zerodha’s Nitin Kamath also echoed something similar, Startup IPO Valuations are also get affected due to these wrong metrics.
Higher valuations are mostly a result of overstating the size of the opportunity. Unreasonable TAM assumptions are a larger problem in India because the revenue opportunity other than lending is limited to the top 2 crore Indians (~1.5% of India) - Nitin Kamath


What’s the way out?
An alternative and additional approach can also be in terms of not spending much time calculating future revenue or reading Gartner studies for factoids that may sound authoritative. Instead, build a bottom-up model that focuses on the size of the opportunity, not the market!
Overall, the solutions are in having right valuations so that projecting unrealistic growth numbers can be avoided. Although SEBI can facilitate but adherence should come more from self-regulations by VC community. A startup is free to ask for a higher IPO price but needs to disclose how valuations are arrived at, SEBI Chairperson Madhabi Puri Buch says.
Also, mindset of Startups growing at all costs and chasing only growth through more discounts and more performance spends should be avoided. It’s during these times that wisdom from Narayana Murthy and Nikhil Kamath can be useful. Zerodha has done fantastically well in spite of being bootstrapped. The way forward is a healthy co-existence of bootstrapping and rightly valued start-ups.
