About
Custify is a customer success platform founded in 2018 and headquartered in Bucharest, Romania, built specifically to help B2B SaaS companies reduce churn, improve net revenue retention, and scale customer success operations without proportionally growing headcount. The company was founded by Philipp Wolf and Dan Alexandru on the premise that most customer success tools either borrowed too heavily from CRM conventions designed for sales teams or lacked the technical depth to surface the product usage signals that determine whether a SaaS customer is healthy, at risk, or ready for expansion. Custify was designed from the ground up as a CS-native platform.\n\nCustify's platform provides a 360-degree customer health scoring engine that aggregates product usage data, CRM activity, support ticket history, NPS scores, and financial metrics into configurable health scores and lifecycle stage models. Customer success managers use the platform to prioritize their portfolio, trigger automated playbooks for onboarding, adoption, renewal, and expansion workflows, and track the impact of CS interventions on retention and NRR metrics. The platform integrates with Salesforce, HubSpot, Intercom, Stripe, and major product analytics tools to create a unified data layer for CS operations.\n\nCustify operates in a customer success platform market projected to reach $3.1 billion by 2026, competing against Gainsight, Totango, and ChurnZero. The company has positioned itself as the focused, CS-native alternative to category leader Gainsight — which many SaaS companies find over-engineered for their current stage — offering comparable depth of health scoring and playbook automation at a lower complexity and cost entry point. Custify's European origin and GDPR-compliant data infrastructure also resonate with international SaaS companies seeking CS platforms aligned with European data residency requirements.
