Google keeps running YouTube at a loss year after year. Same with Gmail and Maps. These aren’t small side projects—they’re massive platforms serving billions of users, burning through infrastructure costs that would sink most companies.
But Google isn’t being careless. They’re applying a calculated strategy that turns conventional product economics on its head. They evaluate these products not by individual profit and loss, but by their contribution to a broader ecosystem that multiplies the value of everything else.
This case study is part of our comprehensive guide on the hidden economics of technical decisions, where we explore how CTOs navigate counterintuitive cost patterns. You’ll see how cross-subsidisation works, how ecosystem lock-in changes customer lifetime value maths, and what decision frameworks you can use to evaluate whether accepting losses makes sense for your business.
What is cross-subsidisation and how does Google use it?
Cross-subsidisation is when profitable products permanently fund unprofitable ones because the combined ecosystem value beats what either could generate alone.
Google demonstrates this at massive scale. Most of their revenue comes from advertising—Search and Ads generate the surplus that funds everything else. Gmail burns cash on storage and bandwidth. Maps loses money on infrastructure and data collection. But all of them feed users back into the advertising engine.
This changes how you evaluate success. You’re not asking if Gmail is profitable. You’re asking if the total ecosystem creates more value than running Search alone would. The strategy needs a cash cow that generates enough surplus to redistribute. For Google, that’s advertising. This pattern of negative per-transaction economics creating overall value appears across different business models—the advertising business doesn’t just support loss-making products, it depends on them to stay dominant.
What is ecosystem lock-in and why does it justify running products at a loss?
Ecosystem lock-in happens when users become dependent on an interconnected suite of products, making switching costs pile up until leaving becomes too expensive.
Google builds this by connecting everything. Your Gmail account logs you into YouTube. Maps integrates with Search. Calendar syncs with Meet. Each additional product increases the friction of leaving.
The economic justification is straightforward once you understand ecosystem value—each product increases total customer lifetime value across the ecosystem. A user who only uses Search might generate $X in advertising revenue. A user who also uses Gmail, Maps, and YouTube might generate $5X because they’re spending more time in Google’s ecosystem.
Switching costs emerge from investments in training, customisation, and integration that would need replicating with a new provider. Think about migrating years of email out of Gmail. The accumulated dependency makes leaving feel impossible.
The value users derive from a product depends on how many other users are on the same network. Maps is more useful when everyone you meet can share locations. The more people locked into the ecosystem, the more valuable it becomes for everyone else.
When you measure customer lifetime value across the whole ecosystem, the losses on individual products become warranted. You’re paying to increase total ecosystem value by keeping users locked in.
How do network effects change the economics of product investments?
Network effects flip the usual cost-benefit analysis. In traditional economics, each customer costs roughly the same to acquire and generates roughly the same value. In network effect markets, each new user makes the product more valuable for everyone else.
This fundamentally changes acquisition economics. In network effect markets, customer acquisition costs go down over time because the value of joining increases. Early users are expensive to acquire. Later users are cheaper because the network is already valuable.
YouTube shows how this plays out. As more creators upload content, the library becomes more valuable. As more viewers show up, creators have more incentive to publish there. Upon reaching critical mass, a bandwagon effect results.
Network effects create winner-take-all dynamics. The dominant player captures disproportionate value because users cluster where everyone else is. This justifies accepting higher losses early to reach the dominant position faster.
The maths shifts from linear to exponential. You’re not asking if the product is profitable next quarter. You’re asking whether reaching market dominance—where network effects generate self-sustaining growth—creates sufficient return to offset the total investment.
How do you calculate the opportunity cost of strategic investments?
Opportunity cost is the value of the next-best alternative you forego when making an investment decision. For strategic losses, you’re comparing the value created by funding a loss-making product against alternative uses of those resources.
The calculation requires identifying viable alternatives and estimating their expected returns. Each project commitment represents alternative initiatives not pursued. You could improve profitable products, return capital to shareholders, or acquire complementary businesses.
The framework includes tangible and intangible returns. Tangible returns are straightforward—revenue growth, cost savings, market share gains. Intangible returns are harder to quantify but may exceed tangible returns in strategic value—competitive moat creation, strategic positioning, option value.
Take Maps as an example. Google could have invested those billions into expanding Search or returning cash to shareholders. The opportunity cost calculation compares owning local search dominance and mobile positioning against those alternatives.
Key factors include expected value from prioritised alternatives, market timing considerations, strategic alignment, and talent utilisation efficiency. Time horizon matters because strategic value takes years to materialise.
The common mistake? Ignoring intangibles or underestimating competitive dynamics. Without opportunity cost analysis, organisations risk pursuing suboptimal investments that consume limited resources.
Why would a tech company intentionally run products at a loss for years?
Strategic losses create long-term value through ecosystem lock-in, competitive moats, and platform dominance. The decision makes sense when customer lifetime value across the ecosystem exceeds what individual product profitability requires.
Market share acquisition in winner-take-all markets justifies extended losses because dominant positions capture exponential value. Google grew dominant quickly because they could service people globally without manufacturing or delivery constraints.
Infrastructure investments like YouTube and Maps create competitive moats protecting the profitable core business. If Google abandoned YouTube, a competitor would fill that space and attack Search. Running YouTube at a loss is cheaper than fighting a well-funded video competitor.
Loss-making products serve as customer acquisition channels feeding users into profitable ecosystem components. Gmail gets users into Google’s ecosystem. Once there, they use Search, see ads, and generate revenue offsetting Gmail’s costs.
Amazon’s 1997 shareholder letter stated they measured success by customer and revenue growth, not profitability. They made bold investment decisions where they saw sufficient probability of gaining market leadership.
Google can sustain decades of YouTube losses because advertising profits are sufficient. Startups without profitable products face timelines measured in months rather than years.
What are the infrastructure costs of running products like YouTube at scale?
Infrastructure costs for video platforms include storage, bandwidth, transcoding, content delivery networks, and redundancy at global scale. YouTube processes hundreds of hours of video uploads per minute, each requiring storage, multiple transcoded versions, and global distribution.
Bandwidth costs alone can exceed revenue per user. Cloud providers charge up to $0.09 per GB transferred out. Data transfer expenses constitute a big portion of cloud costs for data-heavy workloads.
YouTube uses the TPU v5e platform to serve recommendations to billions of users, delivering up to 2.5x more queries for the same cost compared to previous generations. Even with Google’s infrastructure advantages, the costs remain substantial.
Content delivery network expenses scale with user base and viewing patterns. You need servers distributed globally to reduce latency, plus redundancy for availability. For YouTube, the infrastructure investment makes economic sense through video search dominance and advertising integration—not through direct revenue.
How does Google’s ecosystem strategy compare to Amazon’s approach?
Google’s strategy relies on advertising revenue cross-subsidising free consumer products. Amazon’s approach uses retail and marketplace revenue to fund AWS, Prime benefits, and infrastructure.
The monetisation models differ fundamentally. Google monetises attention and data through advertising. Amazon monetises transactions through retail and cloud services. Both create ecosystem lock-in through different mechanisms—Google via data integration, Amazon via Prime membership.
In 2024, Amazon’s total revenue grew 11% to $638B, with AWS contributing $108B (19% growth) and operating income of $68.6B (86% improvement). This represents dramatic evolution from AWS’s $4.6B revenue ten years earlier.
AWS ran at a loss for seven years before reaching profitability, demonstrating an alternative trajectory. It started as infrastructure supporting retail, then opened to external customers and transformed into the most profitable division.
Google’s products like YouTube may never be profitable standalone. Amazon proved strategic losses can evolve into profit centres with the right business model. Both companies emphasised long-term market leadership over short-term profitability.
What frameworks exist for evaluating strategic loss investments?
Effective frameworks integrate opportunity cost analysis, customer lifetime value modelling, ecosystem value assessment, and competitive positioning. You need all four to make informed choices about accepting losses.
Our guide on evaluating long-term strategic investments provides detailed frameworks for these decisions. The decision matrix evaluates financial returns timeline, ecosystem effects, network effect strength, competitive moat creation, and alternative resource uses. Risk assessment must weigh two scenarios: reaching profitability versus creating strategic value through sustained losses.
Effective frameworks quantify direct product economics first—customer acquisition cost, lifetime value, and contribution margin—then layer on ecosystem effects. The analysis examines how each product increases value of other products and raises switching costs.
Time horizon analysis determines how long losses can be sustained before requiring profitability or strategic value realisation. These decision frameworks for time horizons map paths to value capture with measurable milestones and define trigger points for continuing versus discontinuing investment.
Annual planning connects technical initiatives to strategic business priorities enabling optimal resource allocation. Standardised evaluation criteria with weighted scoring enable multi-initiative comparison.
Common failure modes include over-optimistic lifetime value projections, ignoring opportunity costs, and underestimating competition. Stress-testing assumptions and comparing against historical performance helps combat this.
The framework must be tailored to your business model. Advertising-funded differs from subscription-based differs from transaction-based. Google’s framework wouldn’t work for a SaaS company without modification.

FAQ Section
How long can a company afford to lose money on a product?
The sustainable timeline depends on available cross-subsidisation resources, credible path to strategic value creation, and competitive dynamics. Google can sustain decades of losses on YouTube because advertising profits are sufficient and ecosystem value justifies the investment. Startups without profitable products to fund losses face much shorter timelines measured in months rather than years.
What makes some strategic losses worth it and others not?
Successful strategic losses create ecosystem lock-in, competitive moats, or platform dominance that multiplies value across the business. Failed strategic losses lack clear mechanisms for value capture, have weak network effects, or face insurmountable competitive disadvantages. The distinction lies in rigorous opportunity cost analysis and realistic assessment of ecosystem effects.
When should a CTO decide to run a product at a loss?
When customer lifetime value across the ecosystem exceeds product-specific costs, network effects create winner-take-all dynamics justifying market share acquisition, the product creates competitive moats protecting profitable core business, and opportunity cost analysis shows higher returns than alternative resource allocations. Never accept losses without quantified strategic value justification.
How do I know if my product loss will pay off later?
Establish measurable milestones for ecosystem adoption, user engagement, and competitive positioning. Define trigger points for continuing versus discontinuing investment. Monitor lifetime value trends, ecosystem integration metrics, and competitive market share. Google’s continued YouTube investment is justified by growing ecosystem integration and advertising revenue contribution, providing evidence of strategic value realisation.
What’s the difference between a loss leader strategy and cross-subsidisation?
Loss leaders are temporarily priced below cost to attract customers who purchase profitable products, with the expectation the loss leader may eventually become profitable. Cross-subsidisation involves one product permanently funding another’s losses because the combined ecosystem value exceeds what either could generate independently. Google’s approach is cross-subsidisation because YouTube may remain unprofitable indefinitely—the value lies in ecosystem effects, not eventual standalone profitability.
Why does Google keep running YouTube even though it loses money?
YouTube creates ecosystem lock-in through user-generated content and viewing habits, provides video search dominance that protects core search business, generates advertising inventory integrated with Google’s ad platform, and creates competitive moats preventing rivals from building comparable platforms. The ecosystem value and strategic positioning justify infrastructure costs that exceed direct revenue.
How do switching costs contribute to ecosystem lock-in?
Switching costs accumulate as users integrate multiple products into workflows, store data across services, and build dependencies on interconnected features. The more Google products you adopt, the harder and more expensive leaving becomes. This compounds customer lifetime value because retained users generate revenue across multiple products over extended timeframes.
Gmail versus YouTube: which has better strategic justification for losses?
Both justify losses through different mechanisms. Gmail creates ecosystem entry points with minimal infrastructure costs and strong lock-in through email dependency. YouTube requires substantial infrastructure investment but provides video platform dominance and advertising inventory. Gmail’s better margin profile makes it easier to justify, but YouTube’s competitive moat may create more strategic value.
Can startups apply Google’s loss leader strategy without Google’s resources?
Startups must be more selective about strategic losses due to limited runway and lack of profitable products for cross-subsidisation. Focus on products with strong network effects, clear path to ecosystem value, and achievable thresholds for reaching dominance. Venture funding can temporarily substitute for cross-subsidisation but requires faster timeline to strategic value realisation or profitability.
How do opportunity costs compare across different strategic investment options?
Compare the expected value of each option including both financial returns and strategic benefits. Strategic losses must generate higher risk-adjusted returns than alternatives like improving profitable products, returning capital to shareholders, or acquiring complementary businesses. Use consistent evaluation frameworks across options to enable valid comparison.
What are the risks of running products at a loss for too long?
Risks include depleting resources needed for profitable core business, failing to achieve strategic value before competitive landscape shifts, creating organisational acceptance of unprofitability that spreads to other products, and opportunity costs of foregone alternatives. Establish clear milestones and discontinuation criteria to limit exposure.
How does platform business model economics differ from traditional product economics?
Platform economics exhibit network effects where value compounds with user base, winner-take-all dynamics that concentrate value in dominant players, and indirect monetisation where free users create value through attention, data, or enabling paid user acquisition. Traditional product economics show linear relationships between costs and value. This fundamental difference justifies higher strategic losses in platform businesses.
