Trailspark evaluates B2B product-led growth accounts using product, marketing, CRM, warehouse, and web activity, then returns scores and reasoning to connected tools. Its scoring combines product usage, demand-generation signals, and ideal customer profile fit, with explanations in plain language. Buying Group Intelligence identifies engaged, latent, and missing roles at an account. The platform evaluates acquisition, expansion, and renewal motions. Two-way CRM sync with HubSpot and Salesforce writes scores and reasoning into CRM fields. Other named connections include Segment, RudderStack, Marketo, Qualified, Zapier, BigQuery, Slack, Clay, Reo.dev, and webhook-compatible tools. A webhook endpoint can accept behavioral events from HTTP-capable sources. Each unique account counts once per billing month, while signal counts represent ingestion capacity rather than a per-signal charge. Trailspark says direct contact identifiers are not sent to its AI sub-processor, but configured signal content passes through as supplied. The free plan covers 25 accounts per month; Starter is listed at $250/mo as an introductory rate, against a $500/mo list price.
