WARNING: Runway is between 6 and 12 months. Monitor burn rate closely. Initiate fundraising outreach immediately since venture rounds take at least 5 months.
A 15% reduction in operating costs extends your runway by +9.4 months (to 19.8 months).
Suggested: Review non-essential SaaS, vendor contracts, or optimize infrastructure costs.
Increasing sales/mrr by 15% extends your runway by +4.3 months (to 14.6 months).
Suggested: Focus on closing near-term pipeline, cross-selling existing users, or optimizing pricing tiers.
To secure a safe 18-month cash runway, you need to secure a minimum of $67,664 in funding.
Suggested: Start prepping investor decks immediately. Typical startup funding rounds take 4-6 months to close.
