Approck: marketplace, acquisition operations, and forecasting

Seller data, listing preparation, acquisition analysis, and investor reporting needed repeatable workflows while the public marketplace stayed live.

Built and operated the marketplace, internal acquisition CRM, forecasting tools, and investor-reporting workflows.

Owned product delivery and contributed hands-on development across the public marketplace and internal acquisition tools while coordinating developers. Built a CRM for application records, shared contacts, verification evidence, and listing preparation, with role-based access and activity history. Developed cohort forecasting with RevenueCat, Adapty, and Apphud, including a mode that assumes no new subscribers. Kept seller-reported figures separate from provider metrics in the valuation intake. Managed post-close investor relations, P&L reporting, and payout coordination. Configured GA4, GTM, HubSpot, Apollo, and 7+ other acquisition trackers; built 10+ Python/n8n automations.
