Technology Industry Deep Dive: Complete Framework for Case Interviews

Master technology consulting cases with this comprehensive guide covering SaaS economics, platform strategy, hardware margins, and tech M&A valuation frameworks.

Technology cases appear in roughly 12% of MBB consulting interviews and are increasing in frequency as tech permeates every industry. Unlike traditional industries with stable business models, tech cases often involve rapid growth, winner-take-all dynamics, and business models that monetize users long after acquisition. This guide provides the complete framework to excel in technology cases.

Products and Services Landscape

Technology spans multiple distinct sub-sectors with fundamentally different economics. Identifying the sub-sector immediately shapes your entire analysis.

Sub-SectorKey Products/ServicesTypical MarginsKey Success Factors
Enterprise SaaSSubscription software (CRM, ERP, HCM, collaboration)Gross 70-85%, Operating 15-25%Net revenue retention, CAC payback, land-and-expand
Consumer SoftwareApps, gaming, productivity toolsGross 80-95%, Net varies widelyDAU/MAU, engagement, monetization
Cloud InfrastructureIaaS, PaaS (AWS, Azure, GCP)Gross 60-65%, improving with scaleMarket share, enterprise workload capture
HardwareDevices, components, networking equipmentGross 30-45%Supply chain, R&D cycles, ecosystem lock-in
SemiconductorsChips, processors, memoryGross 45-65%Fab capacity, design wins, Moore’s Law
Advertising/PlatformsSearch, social media, marketplacesGross 60-85%User engagement, data, ad inventory
IT ServicesConsulting, system integration, managed servicesGross 25-35%Utilization, talent, client relationships

Based on our analysis of technology cases, the most common scenarios tested are SaaS (35%), platform/marketplace (25%), and hardware (20%).

Revenue Tree: Understanding Tech Economics

Technology business models differ significantly from traditional industries. The dominant models are:

1. Subscription/SaaS Model

ARR = Customers × Average Contract Value
Growth = New ARR + Expansion ARR - Churned ARR

2. Transaction/Platform Model

Revenue = GMV × Take Rate
GMV = Transactions × Average Transaction Value

3. Advertising Model

Revenue = Impressions × CPM / 1000
or
Revenue = Clicks × CPC

SaaS Unit Economics Deep Dive

Understanding SaaS unit economics is critical for technology cases:

MetricDefinitionBest-in-ClassWarning Signs
Net Revenue Retention (NRR)Revenue from existing customers this year / last year>120%<100% indicates net contraction
Gross Revenue Retention (GRR)Revenue retained (excl. expansion)>90%<85% indicates churn problem
CAC PaybackMonths to recover customer acquisition cost<12 months>24 months is concerning
LTV:CAC RatioLifetime value / Customer acquisition cost>3x<2x means unprofitable growth
Magic NumberNet new ARR / Sales & Marketing spend>0.75<0.5 indicates inefficient spend
Rule of 40Revenue growth % + Operating margin %>40%<20% is below healthy threshold

Cost Structure: Where Tech Dollars Go

G&A5-10%Corporate overheadScale leverage

Key Cost Insight: Operating Leverage in Software

Software has extraordinary operating leverage because marginal cost of serving an additional customer is near zero. This means:

  • Early-stage companies often operate at significant losses while investing in growth
  • At scale, software companies can achieve 25-35% operating margins
  • The “Rule of 40” (growth rate + profit margin > 40%) balances growth and profitability

Competitive Landscape

Tech competition follows distinct patterns depending on whether network effects exist.

Porter’s Five Forces for Technology

ForceSaaSPlatforms/MarketplacesHardware
RivalryHigh (crowded categories)Medium-Low (winner-take-most)High (commoditization)
New EntrantsHigh (low barriers to start)Low (network effects defend)Medium (capital-intensive)
Supplier PowerLow (cloud commoditized)LowMedium-High (key components)
Buyer PowerMedium (switching costs)Low (locked into ecosystem)High (price comparison easy)
SubstitutesHigh (build vs. buy, alternatives)Low (few viable alternatives)Medium (competing ecosystems)

Network Effects Framework

Network effects are the defining competitive advantage in technology. Understanding which type applies is essential:

Semiconductor-Specific Considerations

  • Fab vs. Fabless: Foundries (TSMC, Samsung) vs. design-only (Nvidia, AMD, Qualcomm)
  • Process Node: Smaller = more performance, higher cost (5nm, 3nm, etc.)
  • Capacity Constraints: Fab capacity is limited and lead times are long (18-24 months)
  • Cyclicality: Semiconductor demand is highly cyclical

These trends frequently appear in technology cases and shape strategic recommendations.

Important Calculations

These calculations frequently appear in technology cases.

SaaS Valuation Metrics

ARR Multiple = Enterprise Value / ARR

  • High-growth SaaS: 10-20x ARR
  • Mature SaaS: 5-10x ARR
  • Struggling: <5x ARR

Rule of 40 = Revenue Growth Rate % + Operating Margin %

  • Excellent: >40%
  • Good: 20-40%
  • Concerning: <20%

Magic Number = Net New ARR (Q) / S&M Spend (Q-1)

  • Efficient: >1.0
  • Acceptable: 0.5-1.0
  • Inefficient: <0.5

Unit Economics Calculations

CAC = Total Sales & Marketing Cost / New Customers Acquired

LTV = (Average Revenue per Customer × Gross Margin) / Churn Rate

  • Or: ARPA × Gross Margin × Average Customer Lifetime

LTV:CAC Ratio = LTV / CAC

  • Healthy: >3x
  • Break-even: 1x
  • Unprofitable: <1x

CAC Payback = CAC / (Monthly Revenue per Customer × Gross Margin)

  • Best-in-class: <12 months
  • Acceptable: 12-18 months
  • Concerning: >24 months

Hardware/Platform Calculations

Gross Margin = (Revenue - COGS) / Revenue

  • Premium hardware: 35-45%
  • Commodity hardware: 15-25%

Take Rate = Platform Revenue / GMV × 100

  • Marketplaces: 10-25%
  • Payments: 2-3%
  • App stores: 15-30%

ARPU = Revenue / Active Users

  • Use monthly (ARPU) or annually (ARPA)

Important Considerations

These factors separate strong candidates from average ones in technology cases.

Common Pitfalls

  1. Ignoring Unit Economics: High growth means nothing if LTV:CAC is unfavorable. Always ask about customer acquisition efficiency.

  2. Underestimating Network Effects: In platform businesses, being second often means being irrelevant. Winner-take-most dynamics are real.

  3. Confusing Revenue and Bookings: SaaS companies recognize revenue over time. A $1M deal signed today doesn’t mean $1M revenue today.

  4. Missing the Cohort Analysis: Early customers often have different economics than later ones. Ask about cohort performance.

  5. Overlooking Switching Costs: High switching costs = pricing power and retention. Low switching costs = commoditization risk.

Questions to Always Ask

  • What is the business model (SaaS, marketplace, advertising, hardware)?
  • What are the unit economics (LTV:CAC, CAC payback)?
  • Is there a network effect, and what type?
  • What is the competitive landscape and differentiation?
  • What stage is the company (early growth, scaling, mature)?
  • What is the go-to-market motion (PLG, inside sales, enterprise)?

Red Flags in Tech Cases

Key Takeaways

  • Technology cases require immediate business model identification — SaaS, platform, hardware, and advertising have fundamentally different economics
  • SaaS unit economics are critical: know CAC, LTV, NRR, and the Rule of 40 cold
  • Network effects define tech competition — understand direct, indirect, and data network effects
  • Software has extraordinary operating leverage; expect losses early but high margins at scale
  • Customer acquisition motion matters: PLG vs. sales-led has major cost and scalability implications
  • Key metrics vary by model: ARR/NRR for SaaS, GMV/take rate for platforms, ASP/units for hardware
  • Trends to know: AI transformation, cloud migration, PLG, verticalization, and regulatory pressure
