What is a Series A?
A Series A is usually the first priced round from venture investors, raised to build a repeatable way to win customers. Investors set a valuation and buy preferred stock at a set share price, and early-stage VC firms typically lead the round. Investors expect signs of product-market fit: customers using the product, coming back, and revenue that is growing and predictable.
Why it matters to a revenue leader
Series A money is often spent on sales and marketing, so it frequently funds the first sales leader, the first managers and the first real hiring plan. The board will judge that spend by whether sales becomes repeatable without the founder. For the revenue leader, the Series A plan is the first number with real accountability attached.
Example
Fictitious numbersA company with $1.5 million in ARR raises a $12 million Series A. The plan funds a VP of Sales and 8 account executives, with a target of $4.5 million in ARR within 18 months. At month 9, 3 of the 8 reps have closed a deal without founder help.
