Cash Runway

The 18-Month Rule

Experienced founders and investors agree: maintain at least 18 months of runway at all times. Fundraising takes 6 months, so starting with only 12 months means you're already in crisis mode. With 18+ months, you negotiate from strength, not desperation.

Scenario Planning

• Best Case: Revenue grows as planned, expenses stay flat → longest runway
• Base Case: Revenue grows 70% of plan, some cost increases → realistic runway
• Worst Case: Revenue flat or declining, no new funding → survival runway
• Default Dead: What happens if you raise no more money?

Extending Runway Without Fundraising

• Revenue acceleration: Focus all resources on closing deals faster
• Annual prepayments: Offer discounts for upfront annual payment
• Cost reduction: Every €10K saved = 1 month runway at €10K burn
• Venture debt: Non-dilutive capital to extend runway 6-12 months
• Government grants: R&D credits, innovation funding, COVID recovery programs

When to Start Fundraising

Start fundraising with 6+ months runway remaining. The process typically takes 3-6 months for Series A and beyond. If you wait until you have 3 months left, investors will sense desperation and either pass or offer poor terms.

Runway Planning for German Companies

German SMEs and startups face unique dynamics: (1) Access to KfW loans means less pressure to burn quickly—you can sustain longer with debt. (2) Kurzarbeit (short-time work subsidies) allow temporary cost cuts without layoffs during downturns. (3) Government relationships matter—EXIST grants, BMWK programs, and regional subsidies can extend runway. (4) German banks prefer relationships and personal guarantees over equity rounds. Build conservative runway estimates (24+ months for startups) but remember government support programs and favorable loan terms can bridge gaps.

The Zero Cash Date

Beyond 'months of runway,' calculate your exact 'zero cash date'—the calendar day when your bank account hits zero at current burn. If today is January 15 and you have €300K with €30K/month burn, your zero cash date is October 15. This single date is psychologically powerful: it creates urgency for action, motivates cost cuts, and drives disciplined fundraising. Plan fundraising completion by 60 days before this date. Share this date with your team; it aligns everyone on survival timeline and prevents optimistic delusions.
