Why now: the timing argument every pitch needs

Name the technology, regulation or behaviour shift that makes the idea possible this year and not five years ago. If you cannot, the idea has been possible for years, and someone has already tried it.

Sequoia’s business plan template has ten sections and the fourth is two questions long: the best companies almost always have a clear why now, and nature hates a vacuum, so why has your solution not been built before? The second question is the sharper one. Most ideas that sound good have been possible for a decade, and the founders who tried them are not in the room to say so.

This lesson gives the argument a form. A why-now names a shift, dates it, puts a number on it and shows the idea on the far side of it. It also has a second half that founders leave out: why the window closes, because an advantage that everyone will have in three years is not one. The figure in the middle turns both halves into arithmetic.

Why investors weigh timing so heavily

Bill Gross, who founded the incubator Idealab, scored a couple of hundred companies, half his own and half not, on five factors: idea, team, business model, funding and timing. In his 2015 TED talk he reported that timing explained 42 per cent of the difference between the successes and the failures, more than team or idea, and that funding explained the least. His example was a home-sharing company that had been tried several times before one of them launched into a recession in which ordinary people suddenly wanted to rent out a room.

The number is from one investor’s portfolio and should be held loosely. The direction is not in doubt. Investors have seen the same idea arrive every three years with a new team and the same fate, and the first thing they want to know is what is different about this arrival. A founder who answers with the market size has not understood the question. A founder who answers with a date and a number has.

The three kinds of shift

A technology shift is usually a cost curve crossing a threshold. The cleanest Indian example is mobile data. The Minister of State for Communications told the Rajya Sabha in December 2024 that the cost of a gigabyte had fallen from ₹269 in March 2014 to ₹8.31 in June 2024, while internet users rose from about 25 crore to about 97 crore. Every video-first, vernacular, consumer product built in India after 2017 has that curve as its why-now, whether or not the founders said so. Before the fall a ten-minute lesson cost the student more in data than the lesson was worth. After it the data cost rounded to zero.

A regulation shift is a rule that changed on a date. UPI went live in 2016 and the PIB’s own factsheet traces it from about 2 crore transactions in FY 2016–17 to over 24,162 crore in FY 2025–26, with 741 banks live by July 2026. The Account Aggregator framework rests on RBI directions issued in 2016 and went live with eight banks on 2 September 2021; by August 2026 Sahamati’s dashboard showed 338 million accounts linked and 566 million consents fulfilled. The government made the merchant discount rate on UPI and RuPay debit zero from January 2020. Each of these is a date before which a category of business was impractical and after which it was not. The [India Stack lesson](/library/india-stack-as-market-map) walks through what each one opened.

A behaviour shift is a habit that changed and did not change back. These are the hardest to source and the easiest to fake, so hold them to the same standard: a number from a survey or a platform, with a date, showing the behaviour before and after. A behaviour shift with no number is an anecdote. If the only evidence is that the founders and their friends now do something, that is a sample of eight.

Most strong why-nows combine two of the three. Cheap data plus UPI is the why-now of an entire generation of Indian consumer companies. A regulation that creates consented data plus a model that can read it is the why-now of the next generation of lending. One shift is a reason. Two is a window.

The test: what stopped this in 2021?

Write the year five years before today and ask what exactly prevented a competent team from building this then. The answer must be a constraint, not an absence of courage: the input cost too much, the rule forbade it, the customer did not yet do the thing. Then ask when the constraint lifted, to the quarter if you can. If you cannot name a constraint that existed five years ago and does not exist now, the idea has been possible for at least five years, and the question becomes why it has not worked, which is the subject of the [tarpit lesson](/library/tarpit-ideas-why-they-keep-looking-good).

The second half of the test is the one founders skip. Ask why the idea will not be equally possible for everyone in five years’ time. A shift that lowers a cost for you lowers it for every competitor; the window is the period between the cost crossing your threshold and the cost becoming so low that the shift confers no advantage at all. Inside the window the early company can build distribution, data or a brand before the input is a commodity. After it closes the business is still possible and no longer special. The figure draws both crossings.

A why-now is a date and a number. “Digital India” is neither.

A worked example: lending to kirana stores

A team in Pune wants to lend working capital to small retailers against their actual sales. In 2019 the constraint was data. A kirana’s sales were in cash and in a notebook; the only verifiable record was a bank statement the owner had to download, print and hand over, which meant each loan cost a few thousand rupees to underwrite and the loans were too small to carry it. The idea was known, had been tried, and died of unit economics.

By 2026 two constraints have lifted and can be dated. First, the store’s sales now largely arrive as UPI credits, so the record exists in a bank account rather than a notebook; the PIB factsheet puts UPI at roughly 70 per cent of digital payment transactions and over two thousand crore transactions a month. Second, the Account Aggregator framework lets the owner consent, from their phone, to that bank data being shared with a lender for a defined period, with no printing and no scraping, and the framework has 338 million linked accounts to show that the rails carry real traffic. The why-now sentence: underwriting a ₹50,000 loan to a kirana store cost a few thousand rupees in 2019 because the data had to be collected by hand; since consented data began flowing through Account Aggregators at scale the same underwriting costs a few rupees in API calls, which makes small-ticket working capital viable for the first time.

The second half: the window closes as every NBFC and bank wires the same rails into the same underwriting, which they are doing. The defensible company is the one that uses the two or three years of the window to own the retailer relationship, the repayment data and the distribution through FMCG supply chains, so that when consented data is table stakes the rest is not. Say that in the pitch too. Investors trust a founder who knows when their advantage expires.

Fake why-nows and how to spot them

The trend with no number. “AI”, “post-pandemic”, “India’s digital boom”. Each describes a decade and therefore explains nothing about this year. The fix is to go one level down to the specific cost, rule or behaviour and put a figure on it. Not AI; the cost of transcribing an hour of Hindi speech falling from a human’s day rate to a few rupees, with the date the model that did it became available.

The shift that already happened to everyone. If the why-now is UPI in 2026, the window for most payments-adjacent ideas has closed, because the shift is ten years old and the incumbents it created are large. UPI is a why-now for ideas that depend on something UPI has only just made possible, such as a behaviour that needed a decade of habit to form. It is not a why-now for a payments app.

The shift the founders caused. “Now that we have built the product” is not a why-now. The shift has to be external to the company; otherwise the argument is circular and the investor will notice the circle.

The forecast dressed as a fact. “5G will enable” and “ONDC will unbundle” are predictions. They may be right. Until the number exists they belong in the vision section, not the why-now, and the honest version says so: the window is opening, here is the number that will tell us when it has, and here is what we are doing meanwhile.

How to put it in the deck, and a quarterly check

One slide, placed after the problem and before the solution, with one sentence in the form this lesson has used: in year X doing Y cost Z because of constraint C; since date D the constraint has lifted and the cost is Z′, which makes the idea viable for the first time. Under it, the source of each number in small type, because a why-now with a PIB or RBI or NPCI figure beneath it reads as research and the same sentence without one reads as opinion. If the argument needs two shifts, draw them as two lines crossing one threshold; do not add a second slide.

Then, every quarter, re-check the numbers. Shifts continue after they start. Data gets cheaper, consents grow, a rule is amended, and each quarter either strengthens the sentence or begins to close the window. Keep a single row in a sheet per shift: the metric, the source, the value this quarter, the value last quarter. When the input cost reaches a tenth of your threshold, the why-now has become a why-everyone, and the strategy memo needs a new paragraph.

Nothing here is investment advice. Figures quoted were checked in October 2026 against the sources below and will have moved by the time you read this; that is rather the point.
