In plain English
In technology markets the winner is often not the best product but the one that gets to critical mass first and makes it costly to leave. And the firm most likely to be beaten is the successful incumbent serving its best customers well.
The advanced view
Three mechanics dominate: increasing returns from network effects and complementary assets, which make share self-reinforcing and produce tipping; appropriability regimes (Teece) which determine whether the innovator or the owner of complementary assets captures the rent; and demand-side disruption (Christensen) where a technology that underperforms on the mainstream attribute improves faster than the market's requirement and invades from below.
Frameworks
Network effects
Direct (users value users) and indirect (users value complements). Produces tipping and winner-take-most outcomes.
Standards battle
Compete on installed base, complements and expectations. Options: fight, license openly, or join a coalition.
Appropriability (Teece)
Weak IP plus specialised complementary assets ⇒ the asset owner captures value, not the inventor.
Disruptive innovation
Underperforms on the mainstream attribute, wins on price or convenience, then improves upward.
Exploration vs exploitation
March's trade-off: today's efficiency versus tomorrow's options. Ambidexterity separates the two organisationally.
Adoption and payback arithmetic
Critical mass: value to user > price once installed base > threshold S-curve: adoption slow, then steep, then saturating LTV = ARPU × gross margin / (churn + discount rate) LTV/CAC > 3 and payback < 24 months for a fundable land-grab
Worked example — should we subsidise adoption?
Step 1 of 8
- 1ARPU 600/year, gross margin 70% ⇒ contribution 420
Common pitfalls
- ×Calling every new entrant 'disruptive' — most are simply cheaper competitors.
- ×Assuming an innovation is valuable without asking who owns the complementary assets.
- ×Funding a land-grab where network effects are local, not global.
- ×Killing exploration projects with exploitation-era hurdle rates.
Must know cold
- ✓Weak IP + specialised complements ⇒ innovator loses the rent.
- ✓Tipping happens on expectations as much as on installed base.
- ✓Disruption is a trajectory argument, not an insult.
Exercises
Try each one on paper before revealing the worked solution.
Exercise 1
A media platform has 2m subscribers at 12/month, 2% monthly churn and 55% content gross margin. Content spend rises 20% to cut churn to 1.5%. Does it pay?
