Jan Mathis Rossbach

Owned the full product function for the Austrian market of a fast-growing B2B bike-leasing platform —

building product structures, processes, and delivery capability from scratch in a newly established subsidiary.

• • Built the product roadmap and backlog infrastructure, taking end-to-end ownership of prioritisation, OKR definition, and delivery alignment across an 8-person cross-functional team — without direct line management authority.

• • Led a high-stakes migration to a new external Insurance provider, managing scope, stakeholder expectations, and technical dependencies across teams to deliver a fully operational product setup without disrupting live operations.

• • Established sprint rituals and a continuous refinement process that significantly reduced carryover between cycles and gave engineering and operations a shared, trusted prioritisation framework.

• • Identified and drove scalability improvements that reduced manual operational overhead, directly freeing up team capacity for higher-value product and customer work.

• • Served as the single point of contact between C-level leadership and engineering, independently translating company strategy into OKR-driven product initiatives

• • Delivered the technical and product-side onboarding infrastructure for enterprise customers with 5,000+ employees — enabling Sales to close and operationalise large-account deals without manual product intervention.

Owned end-to-end delivery of key product and digitalisation initiatives across product, IT, and operations —

acting as project lead on multiple workstreams in a fast-scaling market-entry environment.

• • Conceived and delivered full digitalisation of the end-to-end contract workflow across sales, leasing bank, and customers using Salesforce + DocuSign — cutting contract turnaround from 14 days to 3–4 days (~75% faster) and reducing error rate from 30% to under 5%.

• • Architected and led the integration of 5+ third-party APIs, connecting external partners into a unified and maintainable system landscape — reducing new partner onboarding time by an estimated ~60%.

• • Drove product trade-off decisions across delivery speed, technical debt, and scalability — taking ownership of outcomes rather than escalating, in a team of ~8 with no dedicated product manager above.

• • Took ownership of onboarding and mentoring new team members — reducing estimated ramp-up time by 3–4 weeks through structured documentation, process walkthroughs, and direct knowledge transfer.
