The Golden Rule: Raise for 18 Months
Venture capitalists and seasoned founders generally agree that you should raise enough money for **18 months of runway**. This gives you 12 months to focus on growth and 6 months to raise your next round of funding.
Milestone Funding
Instead of raising for a random date, identify the **Key Milestone** (e.g., $1M ARR, 100k users) and raise enough to reach it with a 20% margin for error.
The 20% Buffer
Hiring takes longer than you think. Customer acquisition costs fluctuate. A **20% Buffer Reserve** is the safety net that prevents emergency "bridge" rounds.
Three Biggest Funding Mistakes
Founders often get the math wrong in their first pitch deck. Avoid these pitfalls:
Ignoring Fully-Loaded Costs
A $10,000/mo salary actually costs the company ~$12,500 after taxes, benefits, and equipment. Always calculate "Fully Loaded" payroll.
Scaling Marketing Too Early
Raising $2M to spend $1M on Facebook ads before finding Product-Market Fit is the #1 way to burn through your runway without growth.
Underestimating General OPEX
Office space, SaaS subscriptions for the team, legal fees, and insurance add up. These "invisible costs" can eat 10-15% of your funding if ignored.
