<p class="mb-2">Higher investments enable better growth through increased marketing, infrastructure, and customer success capabilities. This affects instance acquisition rates and reduces churn.</p>
<p class="mb-2"><strong>Mathematical Impact</strong></p>
<ul class="mb-2" style="font-size: 0.8rem;">
<li><strong>Instance Scaling Factor</strong> = √(Investment Amount / CHF 500,000)</li>
<li><strong>Churn Reduction Factor</strong> = max(0.7, 1 - (Investment - CHF 500,000) / CHF 2,000,000 × 0.3)</li>
<li><strong>New Instances per Month</strong> = Base Rate × Scaling Factor</li>
<li><strong>Adjusted Churn Rate</strong> = Base Churn × Reduction Factor</li>
</ul>
<p class="mb-0 text-info" style="font-size: 0.8rem;"><strong>Example:</strong> CHF 1M investment = 1.41× more instances + 25% lower churn than CHF 500K base.</p>
