# L1 Advisory > L1 Advisory builds AI-powered revenue systems for B2B founders, CEOs, and COOs. Engagements span sales engine design, go-to-market strategy, operating-system rebuilds, and AI implementation inside business operations — delivered as sprints, 90-day projects, or fractional retainers. L1 Advisory is the consulting practice of Viktor Lehetskyi, a 17+ year B2B sales operator based in Europe. The firm works with founders whose first playbook has stopped scaling: sales is unpredictable, GTM feels like guesswork, and operations are eating the leadership team's time. Every engagement is built around outcomes measurable on a dashboard, not a deck. Languages: English, German. ## Services - [Services overview](https://l1advisory.com/services/): Three engagement types — (1) Audit & Opportunity: end-to-end analysis of sales system and operations, identifying bottlenecks and AI ROI; (2) Strategy & System Design: GTM and internal systems designed as one engine combining sales process, data flows, and AI use cases; (3) Build & Scale: implementation and operation of the system, from sales frameworks to AI agents and workflows. - [Packages](https://l1advisory.com/packages/): Three productized tiers — BASIC (1-month rapid analysis with quick-fix solutions, 8h workshops, ICP and outreach materials), PRO (deep audit + one-year growth roadmap, 16h workshops, GTM strategy, channel prioritization), and a senior tier with hands-on build & operate support. - [Case Studies](https://l1advisory.com/case-studies/): Practical examples — outbound rebuild for a B2B SaaS company, 90-day GTM sprint for a European fintech entering a new market, AI replacement of three manual processes inside a consulting firm. - [Vacancies](https://l1advisory.com/vacancies/): Currently hiring an AI Workflow Intern — hands-on automation work in Make, Zapier, n8n, and AI tooling. ## About - [About Viktor Lehetskyi](https://l1advisory.com/about-us/): Founder and Principal. 17+ years in B2B sales across European markets, from individual pipeline ownership to GTM strategy and partnerships.
