DoorDash's v1 was 8 PDF menus on a static HTML website

The early days of DoorDash, version 1.0, consisted of a static HTML page with 8 restaurant menus in PDF format and a Google Voice number.
The initial version was created in just 45 minutes, showcasing how simplicity can evolve into a widely-used product over time.
Lessons from implementing Minimum Viable Products (MVPs) over the past decade reveal common challenges like inconclusive testing and false negatives.
Product development struggles with competing in existing markets, inadequate user insights, and local optimization, among other issues.
Testing MVPs often leads to ambiguous results and can sometimes cause false restarts, requiring constant reevaluation and refinement of the product.
Creating follow-up tests is crucial but challenging due to the influence of previous tests on user perceptions and expectations.
Learning from existing successes and failures in a market can provide valuable insights for startups entering established sectors rather than pioneering new categories.
While MVPs have their place, some product categories and stages may not align well with the concept, especially in cases requiring significant upfront investment.
Overreliance on data over genuine customer insights poses a risk in product development, highlighting the importance of strategic judgment and qualitative understanding.
The startup journey involves shipping multiple MVPs, learning from failures, and iterating persistently to navigate the challenges of building a successful product over time.
