Built by someone
who's sat on
both sides.
For the operator who's accountable when it has to work on Monday morning - the cutover, the renewal, the migration, the AI agent. Operator-grade templates and playbooks for the enterprise IT stack, built from real scenarios, not consultant theory.
Enterprise IT is written by everyone except the person it lands on.
Vendors sell the product. Consultants bill the programme and leave. Analysts draw the quadrant. Almost nobody writes for the person who is still in the seat on Tuesday - when the cutover failed at 3 a.m., when the renewal auto-rolled at +18%, when the agent shipped on data nobody had cleaned.
Vihren Labs is the catalogue I wish I had had in that seat. The operating detail, written down - by someone who has been on call for it, on both sides of the table. The purpose is narrow and on purpose: take fifteen years of pattern-recognition and turn it into tools an operator can open on Monday and use by Friday.
Who I want to help
If your name is on the decision when it goes wrong, this is for you.
The problems I want to solve
Governance failures kill programmes the technology would have survived.
Runsheets, freezes and rollback criteria - named owners, pre-agreed, before T-day.
Cutovers fall apart at 3 a.m. because the rollback was never a decision.
A 52-check readiness matrix and an hour-by-hour run sheet that holds when twelve people disagree.
Renewals are lost to the information the vendor has and you don't.
The true 3-year TCO, the notice-period trap, and what the distribution channel already knows.
AI projects get cancelled for want of an operating model, not a better model.
A use-case gate, a governance register, and a named owner after launch - decided before you build.
Master data nobody owns - so every report is "wrong" and every agent inherits the mess.
Field-level quality scoring, a maturity read, and an operating model with real decision rights.
Compliance run as document theatre instead of operational evidence.
Registers with real article numbers - EU AI Act, DORA Article 28 - built to be walked by an auditor in 30 minutes.
The standard is the same across all of it: run on the obligation, build governance like architecture, concrete beats abstract. Operator-grade, not consulting - you buy it, you own it, no subscription. Read the Operator Standard

Frequently asked
What is Vihren Labs?
Vihren Labs publishes operator-grade templates, workbooks, courses and playbooks for the enterprise IT stack - SAP S/4HANA migration, master data management, IT procurement, programme delivery, SSC/GBS transformation, and EU regulatory compliance (DORA, EU AI Act). Every product is built from real scenarios: real SAP T-codes, real regulation article numbers, real cutover-night failure modes.
Who makes Vihren Labs products?
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 SAP S/4HANA migrations, IT vendor procurement from the distribution side, EU regulatory rollouts, and large shared-services / GBS transitions across Europe. PRINCE2 Practitioner, Six Sigma. Every product is written from lived practitioner experience, not consultant theory.
Are Vihren Labs products consulting, or legal or tax advice?
No. They are downloadable, operator-built templates and playbooks you run yourself - not consulting. The regulatory compliance products are organizational and evidence tools, not legal opinions; confirm your specific obligations with qualified counsel.
What courses does Vihren Labs offer?
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.
Are the products a subscription? What about the courses, and the higher tiers?
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.
Who are Vihren Labs products for?
The IT operator who has to make the system work on Monday morning - not the executive who reads the slide deck. Typical buyers are SAP migration leads, master-data and MDG owners, IT procurement and vendor managers, programme and PMO leads, SSC/GBS transition managers, and compliance owners working on DORA or the EU AI Act.
Where can I buy Vihren Labs products?
