FAQ
What is startup runway?

Runway is the number of months the current cash balance could cover a positive monthly net burn, assuming the entered cash collections and costs stay constant. It is one planning signal, not a prediction or investor requirement.

What's the difference between gross burn and net burn?

Gross burn is your total monthly expenditure — all costs before any revenue. Net burn is gross burn minus revenue. If you spend ₦2M/month and earn ₦800k/month, your net burn is ₦1.2M/month. Runway is calculated using net burn.

How do African startups typically extend runway?

Test actions you can control: remove unused subscriptions, renegotiate vendor commitments, delay discretionary spend, shorten collection cycles, and model a smaller hiring plan. Check employment and contract obligations before changing pay or staffing.

What runway should I target before raising funding?

There is no universal target. Set an internal minimum that covers the time needed to reach the next financing or operating milestone, plus a contingency for slower collections and unexpected costs.

How to Extend Runway

Immediate Actions

  • Audit all SaaS subscriptions — cancel unused tools
  • Renegotiate office rent or move to co-working
  • Pause paid ads if CAC is not justified
  • Offer equity top-ups in exchange for salary deferrals
  • Switch cloud providers or downgrade tiers

Revenue Acceleration

  • Focus sales on annual prepaid deals (boost cash immediately)
  • Reduce payment terms from 30 to 7 days
  • Upsell/cross-sell existing customers (zero CAC)
  • Launch a "lifetime deal" to inject cash

Runway Red Zones
