Key Topics Covered
SaaS Fundamentals: ARR, Churn, NDR & LTV/CAC
Covers why recurring revenue commands premium valuations, how Net Dollar Retention above 100 percent indicates net expansion within the existing customer base, the LTV/CAC ratio as the core unit economics test where 3x or above is healthy, and the distinction between MRR, ARR, bookings, billings, and recognized revenue.
Valuation Framework: Rule of 40, Growth-Adjusted Multiples & EV/Billings
Explains the Rule of 40 that sums revenue growth rate and EBITDA margin as a quality screen, covers growth-adjusted revenue multiples that normalize for different growth rates across peers, and introduces EV/Billings for companies where deferred revenue creates a gap between cash collection and revenue recognition.
Cohort Analysis, Leaky Bucket NDR & SaaS Quick Ratio
Details how cohort analysis tracks retention and expansion by customer vintage to identify whether NDR is improving or deteriorating over time, explains the leaky bucket problem where a company can show healthy NDR while losing a significant percentage of customers each year masked by upsells to remaining accounts, and covers the SaaS Quick Ratio.
M&A Accounting: Deferred Revenue Haircut, Section 382 & Ratchets
Walks through the deferred revenue haircut where acquired deferred revenue is written down to fair value under purchase accounting, destroying one to two quarters of recognized revenue post-close, covers Section 382 NOL limitations triggered by ownership changes, and explains ratchets in late-stage venture financing that protect investor returns.
Emerging Themes: Burn Multiple, GenAI Impact & Terminal Value
Covers the Burn Multiple as a capital efficiency metric measuring net burn divided by net new ARR, analyzes how GenAI could compress SaaS gross margins by increasing compute costs and create wrapper business risk for thin-value-add applications built on foundation models, and addresses terminal value construction for companies with negative current EBITDA.
How to Prepare for Technology - Internet & Software Interviews
Know the full SaaS metrics stack: ARR, NDR, LTV/CAC, and the Rule of 40. The basic session builds these from first principles and the advanced session shows how each can be manipulated, so be ready to explain both the headline number and how to detect gaming through R&D capitalization inflating EBITDA margin or billings timing distorting the Rule of 40.
Understand the deferred revenue haircut in software M&A. The advanced session explains that under purchase accounting, acquired deferred revenue is written down to the cost of fulfilling the obligation rather than its contract value, which can eliminate one to two quarters of post-acquisition revenue and make the deal look dilutive even if the underlying business is healthy.
Be ready to discuss the Burn Multiple: net cash burn divided by net new ARR. The advanced session positions this as a superior capital efficiency metric to the LTV/CAC ratio because it captures total company cash consumption rather than just customer acquisition costs, and a Burn Multiple above 2x is generally considered a red flag.
Prepare a thoughtful view on GenAI impact on SaaS. The advanced session covers two key risks: gross margin compression from increased compute and inference costs, and the wrapper business problem where SaaS companies built as thin layers on top of foundation models face displacement if the model provider integrates that functionality natively.

The IB Vine technical prep is beyond helpful, it's so much more fun quizzing myself every now and then vs. reading through the guides again.

Check out IB Vine, specifically the 'IB Vine Select' questions. Once you can get a handle of those, it seems like you are in a spot where you're applying the concepts rather than simply memorizing them

IB Vine has excellent questions, especially multistep ones. In my experience I've gotten grilled on accretion/dilution, bond math, and merger model questions. IB Vine has great practice for all of those.

As a nontraditional transfer student who has been rendered unavailable to many resources at my university (Leadership positions at clubs, immediately behind the recruiting cycle, etc.) IB Vine has been an absolute game changer in my IB prep.

From my experience interviewing FT for IB, it’s not enough to just know the 400 questions anymore (it’s a good starting point) but to look at even more advanced questions. Would recommend IB Vine.

heard all the new kids use IB Vine now. the questions on IB Vine helped me get the concepts down when I had to recruit and make a lot of BB/MM interviews easier than I expected for techs
User Story
Just got off the phone with a kid who interned at a Dallas PE firm. He mentioned that IB Vine helped him secure that internship as well as his Summer Analyst offer, especially since he came from a non-target with no resources.
