Gross Burn vs Net Burn
Gross Burn is your total monthly operating costs (salaries, AWS, marketing), while Net Burn is Gross Burn minus monthly revenue inflow.
Healthy Venture Runway
Venture investors typically recommend maintaining a minimum 18–24 month cash runway to allow adequate time for product milestones and fundraising.
Fundraising Buffer Rule
Start fundraising when you have 6–9 months of runway remaining, as institutional Seed/Series A funding rounds routinely take 3–6 months to close.
