You're accountable
when it has to work
on Monday morning.

Vihren Labs publishes operator-grade templates, workbooks, courses and playbooks for three areas of enterprise operations: AI-ready operations (governing AI agents in production), SSC and GBS transitions, and PMO and transformation delivery - with master data operations as the supporting layer underneath. Every product is built from real operating scenarios, not consultant theory.

Petko Petkov - a 15-year enterprise IT operator who has worked both the vendor-distribution and buyer-operator sides of the table. His work spans master data management and governance - the operating model, and automating product and SKU creation end to end, from ingestion, standardisation, enrichment and categorisation rules through to dynamic SKU generation and touchless quoting - alongside large shared-services / GBS transitions across Europe and programme delivery. PRINCE2 Practitioner, Six Sigma. Every product is written from lived practitioner experience, not consultant theory.

No. They are downloadable, operator-built templates and playbooks you run yourself - not consulting, and not legal or tax advice.

Four operator courses, all live and one-time purchases. The Master Data Academy is a three-course set - Master Data Excellence for Product & SKU Management, for Customer & Business Partner, and for Vendor & Supplier Master - each 10 modules with workbooks, operator templates and a capstone you build against your own organization. Alongside them is The Transition Operator's Course for SSC, GBS and BPO transitions. Each course also anchors a value ladder of standalone workbooks and operator packs in the same line.

No - every Vihren Labs product you can buy today is a one-time purchase on Gumroad: you buy it, download it, and own it, with no recurring fees. That includes all four courses - the three-course Master Data Academy (Product & SKU, Customer & Business Partner, and Vendor & Supplier Master) and The Transition Operator's Course (SSC, GBS & BPO) - which are one-time too. The courses are designed as a three-tier ladder: Tier 1 is the self-serve course you own outright (available now); Tier 2 adds 1:1 sessions with Petko - work reviews and direct guidance as you apply it to your own organisation (planned); and Tier 3 is an enterprise tier - a team-training and rollout model for organisations (planned). Tiers 2 and 3 are engagements, not subscriptions, and are coming in the future. Whatever the tier, the model holds: you are buying a thing or an engagement you own, never a recurring subscription.

The operator who has to make it work on Monday morning - not the executive who reads the slide deck. Typical buyers are SSC/GBS transition managers, programme and PMO leads, transformation leads, operations leaders getting ready to run AI agents, and master-data and MDG owners.
