Core Customer Count Metrics Outcome

New Customers

New Customers: The number of customers acquired in the period: customers whose first paid subscription started in the period.

Formula

New Customers = Count of customers with a new revenue event in the period

Computable definition

The canonical formula in the GASP formula grammar. The MCP server compiles it to SQL over the datasets listed below.

count_distinct(field.customer_id where field.event_type = 'new')

Unit: count

Breakdowns

by_segment: one row per segment value

Notes: Customers whose first paid subscription started in the period (a new revenue event). Reactivated customers return through a reactivation event and are not new. CAC divides by it. by_segment returns one row per customer segment.

Data requirements

Grain: Per event, aggregate monthly · Frequency: Daily sync · Aggregation: aggregate (month) · Staged: no · Main source: Billing.

Field	Dataset	Type
`customer_id`	revenue_event	string
`event_date`	revenue_event	date
`event_type`	revenue_event	string

Example SQL (Postgres)

SELECT (SELECT COUNT(DISTINCT customer_id) FROM revenue_event WHERE event_date >= :period_start AND event_date <= :period_end AND event_type = 'new') AS new_customers

Access: recommended sensitivity tier confidential, access scope unscoped. Guidance your policy engine enforces.

From an agent: with the GASP MCP server, call lookup_metric({ "name": "New Customers" }) or generate_query({ "metric": "New Customers", "adapter": "<your adapter JSON>" }).

What It Tells You

The output of the acquisition engine in logos rather than dollars. New Customers x ACV equals New MRR x 12, so when the two trends part, deal size has moved.
