The standardized measure of predictable revenue generated from subscriptions over a one-year period. For Series A companies, investors look for consistent month-over-month growth in ARR as proof of market traction and the ability to scale the sales engine effectively.
A metric that captures revenue retained from existing customers after accounting for churn, downgrades, and expansion revenue. An NRR above 120% is considered best-in-class, signaling strong product stickiness and the ability to grow account value over time.
The total cost of sales and marketing efforts needed to acquire a new customer. Investors scrutinize CAC to ensure it is reasonable relative to the customer's lifetime value, ensuring that the company is not overspending to fuel growth.
The number of months it takes for a customer to generate enough gross margin to cover the cost of acquiring them. Series A targets typically aim for a payback period of under 12-18 months to demonstrate capital efficiency and cash flow health.
The percentage of total revenue remaining after subtracting the costs of goods sold (COGS), such as hosting and support. B2B SaaS companies generally target gross margins above 70% to indicate a scalable, asset-light business model with room for operating expenses.
The percentage of customers or revenue lost during a given period. Low churn is critical for Series A viability, as high churn indicates product-market fit issues or poor customer success, making it difficult to achieve sustainable, predictable growth.
A heuristic stating that the sum of a SaaS company's revenue growth rate and its profit margin (or free cash flow margin) should be 40% or higher. This metric helps investors balance the trade-off between aggressive growth and operational efficiency.
The relationship between the total lifetime value of a customer and the cost to acquire them. A healthy ratio is typically 3:1 or higher, indicating that the company generates three times more value from a customer than it costs to acquire them.
The predictable revenue a company expects to receive every month from active subscriptions. MRR is the foundational metric for forecasting, budgeting, and tracking short-term growth velocity, serving as the primary input for calculating ARR and growth rates.
Distinguishing between the loss of customers (logo churn) and the loss of revenue (revenue churn) provides a clearer picture of retention health. Investors prefer low revenue churn, as expansion revenue from existing customers can offset the loss of smaller accounts.
Metrics specific to PLG models, such as Product Qualified Leads (PQLs), activation rates, and viral coefficients. These metrics highlight how effectively the product itself drives user acquisition and conversion without heavy reliance on outbound sales teams.
The average time it takes from the first sales interaction to closing a deal. Understanding this metric helps forecast revenue delivery and identify bottlenecks in the sales pipeline, allowing for more accurate cash flow projections and hiring planning.
The total value of opportunities that meet specific criteria to be considered likely to close. Monitoring pipeline coverage (e.g., 3x-4x of target) ensures the sales team has enough qualified leads to hit revenue goals within the forecasted timeframe.
Similar to NRR, NDR focuses specifically on the expansion of revenue from the existing customer base. A high NDR indicates that customers are upgrading tiers, adding seats, or purchasing add-ons, which is a key driver of sustainable SaaS growth.
The ratio of net burn to net new annual recurring revenue over a trailing twelve-month period. A burn multiple of 1x or less indicates efficient use of capital to generate growth, while higher multiples suggest inefficiency or premature scaling.
The percentage of new users who complete a key action that leads to long-term retention and value realization. High activation rates are essential for reducing churn and ensuring that acquired customers actually derive value from the product quickly.
The average annual revenue generated per customer contract. ACV helps companies understand their pricing strategy's impact on sales efficiency and growth, allowing for better segmentation of enterprise versus mid-market sales motions.
A composite metric derived from usage data, support tickets, and engagement levels that predicts churn risk. Proactively monitoring health scores allows companies to intervene with at-risk accounts, thereby protecting recurring revenue and improving NRR.
The percentage of net income that converts into actual cash flow. This metric is crucial for Series A companies to demonstrate their path to profitability and sustainability, showing that growth is not merely an accounting exercise but generates real cash.
An aggregate view of how effectively a company turns marketing and sales investments into revenue. This includes analyzing channel-specific ROI to determine which sales motions (inbound, outbound, partner) yield the highest quality and most efficient growth.
