Validate business ideas by creating a fake prototype or wireframe and selling it to customers first. This confirms demand and secures revenue before you invest time and money into development, which the speaker identifies as the hardest part of validation.

Instead of building an MVP, pitch a one-liner about your solution to a target audience and gauge their reaction. Passionate, unsolicited stories about their pain points signal strong problem-solution fit. This method provides objective validation with minimal resources.

Before writing code, you can string together hyperlinked screenshots in a design tool like Figma. This creates a 'hacky' prototype that feels like a fully built app to potential customers, allowing for rapid, low-cost user testing and validation.

Instead of a traditional product launch, gauge market interest by tweeting about a personal problem and asking if others share it, framed as "Thinking of building an app...". This validates the idea and creates an initial beta list from interested replies before you invest heavily in development.

Instead of waiting for a working product, the founders invested in a conference booth with just screenshots. This early, public validation test, though risky, attracted two crucial prospects who became their first customers. This demonstrated market demand before the product was fully built, a move many founders would avoid.

Instead of building a full app, creating a compelling video of a unique UI/UX concept and posting it on social media can validate demand. For a calorie tracking app in a saturated market, a viral video showcasing a novel interaction pattern generated an 800-person waitlist, proving product-market fit before significant development.

Replace speculative feedback from discovery calls with a process that would be "weird if it didn't work." First, get strangers to pre-pay for a solution. Then, deliver it manually. This confirms real demand (payment) and validates the solution's value (retention) before writing code.

To achieve viral validation on platforms like TikTok, an app must be extremely simple. It needs a core concept that can be explained in just a few words (e.g., "track your acne") and has a strong visual component that is compelling in short-form video content, making it easily shareable.

Crisp.ai's founder advocates for selling a product before it's built. His team secured over $100,000 from 30 customers using only a Figma sketch. This approach provides the strongest form of market validation, proving customer demand and significantly strengthening a startup's position when fundraising with VCs.
