Case Study: Marinus Pharmaceuticals achieves a 50% faster monthly close and seamless audits with BlackLine

Reducing Close Time by 50% & Enabling a “Seamless” Audit

Marinus Pharmaceuticals is a clinical-stage biopharmaceutical company developing ganaxolone. As a public company with limited resources and a lean finance team, Marinus relied on manual, spreadsheet-driven close processes that stretched monthly close cycles to about 30 days and left them exposed as their SEC emerging-growth-company protections ended — they needed audit-ready documentation, visibility, and stronger controls.

Marinus implemented BlackLine’s Modern Accounting Playbook—Account Reconciliations, Task Management, and Bank Transaction Matching—implemented in 4–6 weeks with a three-month time-to-value. The solution cut close time by 50% (to 15 days), automated matching and certification to save staff hours, increased visibility and organized documentation, and enabled a seamless audit that saved roughly 30–40 auditor hours while strengthening the team through cross-training.
