Growth Equity Case Study Prep: Retention, Cash and Ownership

A growth-equity case needs more than a revenue forecast. Show whether customers stay, what growth costs, how much equity the investor owns and whether the price can earn the required return. A company can grow while the investment disappoints.

This guide is for candidates preparing a minority-growth investment case. It is an original practice framework, not a description of a particular employer's interview. Firms vary: some combine growth, control and venture strategies. Read the role and case instructions before deciding how much emphasis to give sourcing, commercial diligence or modeling.

Start with five outputs

Before building tabs, write down the decision, the evidence and the missing information. Use this checklist to keep the model connected to the recommendation.

This emphasis on business evidence has a practical role context. Insight's Diligence & Growth Strategy program describes commercial diligence on software investments. That is one employer's description, not a universal interview syllabus or a claim about current vacancies.

Work the mini-case before reading the answer

All figures below are fictional, in millions of dollars. A software company begins with $10 million ARR. It loses $0.8 million to churn and $0.2 million to contraction, adds $1.5 million of expansion from existing customers, and signs $3 million of new-customer ARR.

Calculate ending ARR, gross retention and net retention. Then identify one reason the headline growth rate could be misleading. Assume no acquisitions, FX changes or metric-definition changes.

Answer: Ending ARR is $13.5 million: 10 − 0.8 − 0.2 + 1.5 + 3. Growth is 35%. Gross retention is 90%, calculated before expansion. Net retention is 105%, calculated after expansion but excluding new customers.

The 35% headline does not reveal who churned, whether expansion came from one customer or how much the new sales cost. Request a customer-level reconciliation and segment the opening cohort. ARR is an annualized recurring contract measure here; it is not recognized revenue or cash collected. Verify the company's definition before comparing it with another business.

Connect the check to the shares

Now assume an investor puts $15 million of primary capital into this fictional company at a $45 million pre-money equity valuation. Post-money value is $60 million and the investor owns 25%, before any other changes. The company receives $15 million before fees.

If the same investor additionally purchases $3 million of existing shares at the same price, it acquires another 5% of the post-primary share count, assuming identical rights and no other instruments. Total ownership becomes 30% for an $18 million check. The company still receives only $15 million; the selling holder receives $3 million.

A later financing gives new investors 20% of the post-round equity and the original investor does not participate. Its 30% falls to 24%. If equity exit value is $100 million, its proceeds are $24 million under the simplified assumption of no preferences, fees, taxes or other claims. That is 1.33× the $18 million investment, not 1.67× calculated using only the primary check.

This exercise does not establish an attractive return. The hold period and cash-flow dates are still missing. The point is to reconcile capital invested, company funding and ownership before discussing the result.

Write a recommendation that can change

Use four sentences as a first draft:

1. State approve, decline or continue diligence under the specified mandate and return objective.
2. Name the strongest supporting business evidence.
3. Name the assumption most likely to break the investment case.
4. State the next test and what result would change your decision.

For the mini-case, “continue diligence” could be appropriate because retention and new-customer economics remain unresolved. That is a conditional practice answer, not the only possible recommendation. A different mandate, price or dataset could support another conclusion.

Avoid smoothing a weak case by raising an exit multiple without support. If the required return needs a particular revenue outcome, reverse the calculation and show the operational hurdle. An explicit stretch assumption is more useful than a model that silently treats it as certain.

Choose preparation based on the remaining gap

If the five outputs above are unfamiliar, rebuild the mini-case and explain each denominator aloud. If you can do that but need a complete practice sequence, inspect the Growth Equity Recruiting & Interview Playbook sample. Its original cases cover customer cohorts, cash needs, sales capacity, primary and secondary capital, dilution, returns and a non-software expansion business. The product page shows the current price and exact scope.

The playbook is a PDF; you build exercises in your own spreadsheet. It includes no personal review, coaching, employer question bank or hiring guarantee. If the role instead centers on leveraged buyouts, compare the existing PE playbook. Foundational valuation and recruiting concepts overlap; buying both is optional.

For early-stage startup evidence and fund economics, use the VC investment-memo preparation guide. For the broader career decision, start with the finance career guide. If your own application needs individual feedback, inspect the separate resume services.

Check before submitting the case

Keep the source of each input, the metric definition and the missing items visible. Check that ownership totals reconcile and all investor checks enter the return calculation. Separate company cash from shareholder proceeds. Finally, ask whether your recommendation changes when retention, hiring capacity, dilution or exit pricing deteriorates.

Historical cloud-company research such as Bessemer's Scaling to $100 Million can help frame metric questions, but its 2021 selected sample is not a current universal benchmark. Your case should stand on the supplied evidence and clearly labeled assumptions.
