Bolt's initial scooter launch in Paris was a disaster, with rampant theft and vandalism of consumer-grade scooters. The key insight was that the unit economics were impossible without controlling the hardware. By developing custom-built scooters that couldn't be easily resold for parts, they dramatically reduced theft and made the business model viable.

While a fusion reactor can't be built in three months, YC pushes hardware and deep tech founders to create a tangible Minimum Viable Proof. This forces them to de-risk the venture by hitting a critical milestone, such as building a small-scale desert prototype or securing key letters of intent, proving traction on a non-obvious timeline.

To innovate at scale, Harness treats each new product as a semi-independent entity. These "startups" have a founder-like PM, go through internal seed/Series A funding stages tied to revenue milestones (e.g., $1M ARR), and are responsible for their own initial founder-led sales.

In a multi-product company, horizontal teams naturally prioritize mature, high-impact businesses. Structuring teams vertically with P&L ownership for each product, even nascent ones, ensures dedicated focus and accountability, preventing smaller initiatives from being starved of resources.

To launch new products and compete with agile startups, embed a small "incubation seller" team directly within the technology organization. This model ensures tight alignment between product, engineering, and the first revenue-generating efforts, mirroring the cross-functional approach of an early-stage company.

Before committing to a costly lease and build-out for a restaurant, the speaker tested the concept with a delivery-only model from a commissary kitchen. This pre-MVP approach, now known as a cloud kitchen, validated the idea with minimal capital and risk.

To ensure continuous experimentation, Coastline's marketing head allocates a specific "failure budget" for high-risk initiatives. The philosophy is that most experiments won't work, but the few that do will generate enough value to cover all losses and open up crucial new marketing channels.

When expanding his law firm, John Morgan uses a 'bullets before bombs' strategy. He first enters a new city with a small, low-cost team and ad budget (the 'bullets') to test viability. Only after seeing positive traction does he commit significant capital and resources (the 'bombs'), de-risking growth.

Validate market demand by securing payment from customers before investing significant resources in building anything. This applies to software, hardware, and services, completely eliminating the risk of creating something nobody wants to buy.
