Stratigraphy Case Gallery

Twelve Companies.
One Pattern.

Each of these firms deposited layers over thirty years. Labor arbitrage, process discipline, scale machinery, margin optimization. Same ocean. Same sediment. The geology beneath determines what can grow above.

Stratigraphy reads the institutional rock record of an organization. The layers are not metaphorical. They are load-bearing. What follows is a diagnostic survey of twelve IT services companies, classified by the permeability of their formation.

CALCIFIED -- The finance ceiling has sealed. Utilization logic governs all decisions. Acquisitions die. Platform plays are defunded. Every transformation CEO is rejected within three to six years. The structure is impermeable.

HARDENING -- The layers are compacting. Scale still functions, but the caprock is forming. Margin discipline is tightening. The window for structural change is narrowing.

PERMEABLE -- The formation allows migration. Different capital structure, different founding axioms, or deliberate rejection of utilization-first logic. New capabilities can push through.

Calcified -- impermeable caprock
Hardening -- caprock forming
Permeable -- migration possible
TCS Calcified

Founded in 1968. Perfected the labor model. Now too optimized to change.

  • $30.2B revenue, 592K employees — but added only 17 people in nine months.
  • New CEO is a 34-year lifer. Leadership succession selects for continuity, not reinvention.
  • 2-5% growth while smaller competitors post 30-50%.
Infosys Calcified

Hired an outsider CEO to transform. He lasted three years. The system reverted.

  • Vishal Sikka (SAP) lasted three years. Salil Parekh restored the old operating model.
  • Lodestone acquisition ($349M): consulting talent subjected to utilization metrics. Most left.
  • High margin, stagnant growth. Quarterly discipline won every quarter but lost the decade.
Wipro Calcified

Revenue declined in FY2024. The trajectory speaks for itself.

  • Thierry Delaporte from Capgemini lasted four years. Replaced by Srini Pallia, a 30-year lifer.
  • Appirio acquisition ran through the utilization filter. Same pattern as Infosys-Lodestone.
  • $10.4B revenue, 233K employees. The structure chose reversion over reinvention.
Cognizant Calcified

U.S.-headquartered but runs the same operating model as its Indian peers.

  • Brian Humphries (outsider, Vodafone) lasted four years. Replaced by Ravi Kumar — 20-year Infosys veteran.
  • $19.7B revenue, 15.3% margin. Built on the same labor arbitrage foundation.
  • Revenue = headcount × rate × utilization. Same equation, different passport.
HCLTech Hardening

Accepted its constraints. Chose survival without transformation theater.

  • 4-6% growth. No dramatic announcements. No CEO fired for insufficient ambition.
  • Understood the structure wouldn't permit metamorphosis. Chose to live within it.
  • Legitimate outcome: a company that knows what it is and doesn't pretend otherwise.
Tech Mahindra Hardening

Bet on 5G as a transformation path. Didn't pay off. New CEO is a 20-year Infosys veteran.

  • CP Gurnani's 5G strategy didn't change the underlying business model.
  • Successor Mohit Joshi: 20 years at Infosys, President. Trained in the same system.
  • Leaders shaped by the old model tend to reproduce the old model.
Coforge Permeable

Led by an executive who left Infosys. Backed by patient PE capital. Different operating logic.

  • Sudhir Singh: left Infosys, built Coforge around capability, not utilization.
  • 56.5% YoY growth. $1.56B Sabre deal. $2.35B Encora acquisition — largest in Indian IT history.
  • Baring Private Equity: 30% stake, five-to-seven-year investment horizon.
Persistent Systems Permeable

Engineering-led, not staffing-led. Small enough to build differently.

  • $1.41B revenue, 24.6K employees. 18.8% YoY growth.
  • Intelligence embedded in the delivery model, not bolted on.
  • Scale built on capability, not volume. Revenue per employee is rising.
LTIMindtree Permeable

Built by an Infosys executive who was passed over. Market value grew tenfold.

  • Sanjay Jalona: 15 years at Infosys, EVP. Wasn't promoted to President. Built LTI instead.
  • $406M quarterly revenue, 17.6% YoY growth under different operating assumptions.
  • The people the big firms didn't promote built the companies that outgrew them.
EXL Service Permeable

Analytics-first from founding. Revenue grows from expertise, not headcount.

  • $1.84B revenue, 14.3% margin. Stock up 40-60% in 2024.
  • Founded on analytics and domain expertise, not labor arbitrage.
  • The market is pricing trajectory, not current revenue. Valuation reflects where it's going.
Mphasis Hardening

PE-owned. The capital structure is different. The operating logic is still forming.

  • Blackstone-backed since 2016. Patient capital changes what the finance layer permits.
  • Vertical focus on banking and insurance. Domain depth over horizontal scale.
  • The window is open but narrowing. PE ownership creates different incentives than public markets.
WNS Hardening

BPO roots, smaller operation. Less institutionally rigid, but the patterns are forming.

  • Business process origin. Not pure IT services, but facing the same industry pressures.
  • Analytics capabilities built on top of process delivery. Less entrenched than the big five.
  • Taken private in 2025. New ownership may change what's possible.
