Figma's expansion into multiple products (FigJam, Slides) wasn't based on abstract strategy but on observing users pushing the main design tool to its limits for unintended use cases. Identifying these 'hacks' revealed validated market needs for dedicated products.

Instead of inventing new features, Prepared identified its most lucrative expansion opportunity by seeing users' painful workarounds. They noticed 911 dispatchers manually copy-pasting foreign language texts into Google Translate—a clear signal of a high-value problem they could solve directly.

"Blocked" customers aren't using a bad alternative; they're doing nothing because no viable solution exists. You can't observe their struggle. Unlocking this latent demand, as Uber did for people who previously wouldn't travel, doesn't just steal market share—it creates a new market entirely.

Intentionally create open-ended, flexible products. Observe how power users "abuse" them for unintended purposes. This "latent demand" reveals valuable, pre-validated opportunities for new features or products, as seen with Facebook's Marketplace and Dating features.

To secure a future for human drivers, Uber is expanding into use cases too complex for current automation. They turned the user "hack" of asking couriers to shop for them into an official "personal shopper" service, creating a pathway for drivers to migrate to more intricate work.

Users often develop multi-product workarounds for issues they don't even recognize as solvable problems. Identifying these subconscious behaviors reveals significant innovation opportunities that users themselves cannot articulate.

Zapier evolved from a simple trigger-action tool by observing how advanced users "hacked" it for unintended purposes. When users treated Google Sheets like databases, Zapier built Tables and Interfaces, proving that emergent behavior is the clearest signal for your product roadmap.

Dara Khosrowshahi describes a two-step innovation process. First, let teams compete to rapidly "hack" a solution and find product-market fit. Second, once a winner emerges, the organization must systematize and automate that solution through engineering to make it scalable and part of the core platform.

Identify how users are already "hacking" your product for unintended purposes (e.g., using Facebook Groups for commerce), then build dedicated features to serve that existing intent. You can't make people do new things, but you can help them do what they already want to do more easily.
