Frequently Asked Questions
Frequently Asked Questions
How much runway do I need?
Ideally 18-24 months. At minimum 12 months. This gives time to achieve milestones and raise next funding round.
How do I extend runway?
Raise funding, reduce expenses (lower burn rate), or increase revenue. Often a combination of all three.
