# Why 70% of Startups Founded in 2021 Are Already Failing

Seventy percent. That’s the sobering statistic that highlights the plight of startups founded in 2021, as reported by PitchBook. While many attribute these failures to economic downturns or rising interest rates, the reality is far more nuanced. The core issue lies in the outdated assumptions founders cling to about market demand and consumer behavior. The pandemic catalyzed a shift in these dynamics, and while founders were riding high during the boom, the rules have changed.

This isn’t just a cautionary tale—it’s a call to reevaluate fundamental business strategies in an era defined by volatility. Investment professionals and founders alike must adjust their evaluative criteria for startup viability, keeping in mind that yesterday’s winning model may lead to tomorrow’s losses.

## What Is Startup Viability?

Startup viability refers to the potential for a new business model or product to succeed in the marketplace. It matters now more than ever as emerging trends in consumer behavior and market needs evolve rapidly, especially following the pandemic. The analogy here is straightforward: consider a ship sailing on calm waters. When a storm hits, the ship must not only withstand the waves but also navigate to a new destination—those that can adjust their sails to meet the changing winds will survive. This adaptability is crucial in today’s landscape, where tools like Hallucinopedia: The AI Tool That Could Revolutionize Knowledge Sharing can aid in understanding market requirements.

## How Startup Viability Works in Practice

1. **Atlassian’s Subscription Shift**: Atlassian, known for products like Jira and Confluence, recently transitioned to a subscription-only model. This shift not only reflects market demand for more predictable pricing but also illustrates how established companies adapt faster than startups often do. This evolution signifies that newer startups should proactively rethink their monetization strategies to remain competitive.

2. **Instacart’s Public Struggles**: Once considered a high-flying unicorn, Instacart has faced difficulties in its efforts to go public. The struggles highlight the instability of consumer demand in a post-pandemic world, as shopping habits shifted dramatically during lockdowns. The failure to effectively adapt to these changes has left even once-promising companies in a precarious position. Companies need to learn from such cases and implement strategies that allow them to pivot effectively, just like leading AI companies are navigating their challenges.

3. **Snapchat Layoffs**: Snapchat’s layoffs this year serve as a stark reminder of the reassessment happening across tech companies. With wages in tech remaining high and growth projections narrowing, Snapchat’s scaling approach had to change. Founders observing this trend must rethink their own workforce management and what constitutes sustainable growth in their ventures. A clear understanding of shifts in workforce dynamics and labor trends is essential, as highlighted in articles like 7 Ways Companies Manipulate Productivity Metrics to Look Busy.

4. **LinkedIn’s Pivot to Job-Driven Model**: After realizing the need to stay relevant amid shifting job market dynamics, LinkedIn actively pivoted to a job-focused approach in its platform services. This decision underscores the notion that flexibility isn’t merely advantageous but essential for survival in the startup realm. LinkedIn’s shift illustrates how startups can benefit from continuously analyzing consumer needs.

## Common Mistakes and What to Avoid

1. **Ignoring Market Signals**: Many founders become overly attached to their initial concept, failing to adapt when market signals change. Take WeWork as a case study—it overestimated demand for co-working spaces before the pandemic and saw massive layoffs and valuation drops as a result. Understanding the impact of such market miscalculations is key, as discussed in the analysis of how cultural phenomena influence market expectations.
