Case 040Market sizing and thesesCore

Tell me about a software trend you follow: AI assistants for accounting practices. Turn it into a thesis for Ganakvik AI, which sells to India's CA firms. Size the reachable market and say what must be true.

Insight PartnersNew York · 2022

1The situation

The trend: AI assistants that draft tax computations, reconcile ledgers and prepare compliance filings for accountants. Ganakvik AI sells such an assistant to chartered accountant (CA) firms in India, priced per seat per month.

Work with these assumptions, and say that the firm count should be confirmed from the professional body's published figures: 90,000 CA firms, of which 30% have five or more staff; firms of that size would buy 8 seats on average at Rs 2,000 a seat a month; and 15% of them adopt such a tool within five years.

2Your task

Size the reachable market and the five-year ARR it implies, then turn the trend into a thesis: what must be true for Ganakvik to be a venture-scale outcome?

Quick check

Roughly how large is the yearly reachable market on these assumptions?

Worked solution

Try it on paper, then open one step at a time.

30-second answerThe answer to give first

The reachable market is about Rs 518 crore a year, and 15% adoption gives about Rs 78 crore of ARR in five years across every vendor. That is a thesis only if one company can take most of it and the market grows beyond the base assumptions. At 60% share the leader has about Rs 47 crore, a good business but not yet a venture outcome; smaller firms, a second product and higher adoption must all come true together.

Step 1How do you turn a trend into something you can size?

A trend is an observation; a thesis is a bet with numbers attached. Saying people are buying more scooters is a trend. Saying a scooter-servicing chain in tier two cities can reach Rs 100 crore of revenue because there will be this many scooters, each serviced this often, at this price, is a thesis. The move is to name the customer, count them, price what they would pay, and apply a believable adoption rate, so each step is an assumption someone can challenge. Interviewers ask about a trend to see whether you can make this move, not whether you can list buzzwords.

Here: 90,000 firms, 30% with five or more staff, is 27,000 firms. Eight seats each is 2,16,000 seats. Rs 2,000 a month is Rs 24,000 a year, so the reachable market is 2,16,000 times Rs 24,000, Rs 518.4 crore a year. Fifteen per cent adoption in five years is Rs 77.8 crore of ARR, shared among everyone selling such tools.

From CA firms to rupees: each box is an assumption you must defendCA firms90,000Five or more staffx 30% = 27,000Seatsx 8 = 2,16,000Rupees a yearx Rs 24,000 = 518 crAdopted in 5 yearsx 15% = 78 crThe questions behind each box:1. How many firms? Confirm with the professional body's count.2. Do 5+ staff firms buy software?3. Is a seat per staff member, or per partner?4. Will a CA firm pay Rs 2,000 a seat a month?5. Who wins: one leader or many tools?If one leader takes 60%:Rs 47 crore of ARRA good company, not yeta venture-scale outcome
Ninety thousand CA firms narrow to 27,000 with five or more staff and 2,16,000 seats, worth Rs 518 crore a year at Rs 24,000 a seat, of which 15% adoption gives about Rs 78 crore of ARR and a 60% leader about Rs 47 crore.
Step 2Is that big enough for a venture fund?

Not on these numbers alone. A leader with 60% of adopted spend would have about Rs 47 crore of ARR. That is a good software company, but a venture fund usually needs a few companies that become several times larger to carry the whole portfolio, so the thesis must explain how the market grows, not just how Ganakvik wins it. Say that plainly; an interviewer respects a candidate who sizes a market and then admits it is small.

Step 3What must be true for it to become a venture-scale outcome?

Three things, each a test you could run. First, smaller firms buy: if the other 63,000 firms take 3 seats each, the seat count nearly doubles to 405,000. Second, price rises with a second product, such as audit or payroll compliance, taking a seat to Rs 4,000 a month. Third, adoption reaches 30%, because AI tools that save hours in tax season spread by word of mouth among accountants. Together those give a market of about Rs 1,944 crore and ARR of about Rs 583 crore at 30% adoption, Rs 350 crore for a 60% leader.

CaseSeatsRs a seat a monthAdoptionARR, all vendors, Rs crLeader at 60%, Rs cr
Base assumptions2,16,0002,00015%7847
Everything must go right4,05,0004,00030%583350
The thesis needs smaller firms, a second product and double the adoption to come true together; that takes the leader from about Rs 47 crore to about Rs 350 crore of ARR.

Close with what would kill it. If the large accounting software makers build the same assistant into products CA firms already pay for, Ganakvik becomes a feature. So the thesis also needs a reason the specialist wins: deeper Indian tax and filing workflows, or data from thousands of firms that improves the assistant faster than a generalist can. The limitation of the sizing is that every input is an assumption; the value is in showing which three would have to move.

Where candidates lose it

The common loss is answering the trend question with enthusiasm and no numbers: AI is changing accounting, and Ganakvik is well placed. Without the firms-seats-price chain the partner has nothing to test.

The second is presenting Rs 518 crore as the opportunity. That is the market if every firm bought; adoption and share take it to Rs 47 crore for the leader, and saying so is what makes the rest of the thesis credible.

What the interviewer asks next

  • What evidence from Ganakvik's first 200 firms would tell you adoption could reach 30%?
  • How would you size the market if pricing were per tax return filed instead of per seat?
  • Which incumbent response worries you most, and how would Ganakvik defend against it?

Asked at Insight Partners, Software, New York, 2022 (Wall Street Oasis): Tell me about a trend in technology/software products you've been following.

← Case 039Nikhravik Beauty, a D2C skincare brand, pays Rs 650 to acquire a customer, and only some customers reorder. When does a customer become profitable?Case 041 →In a superday pitch round, pitch Dakvik Logistics Cloud in 60 seconds: shipping software used by 3,000 online brands at Rs 4 a parcel.
