Lead scoring with LLMs: when it works, when it doesn't, what to ship instead.

Oleksii Liatavskyi is the founder of Martechno, a senior-operator B2B martech consulting studio based in Kyiv, Ukraine. Over the past decade he has architected, deployed, and operated marketing-technology stacks for B2B SaaS companies at Series A through Series C, DevTools teams scaling from solo-founder Pipedrive setups to multi-region Salesforce instances, and FinTech businesses preparing for compliance audits. His day-to-day is the unglamorous side of RevOps: object-model design that holds up under a Series-B headcount jump, lifecycle stage gates that reconcile to revenue, deliverability hardening on multi-domain cold-outreach engines, and Looker/dbt revenue dashboards a CFO can defend in a board meeting. He works exclusively as a senior individual contributor — no leverage model, no junior bait-and-switch. Martechno was founded on the conviction that the marketing technology consulting industry has a quality problem: six-month transformation contracts for what should take six weeks, decks instead of code, Diamond-tier partners that bait the senior architect on the sales call and swap in a junior team for delivery. The studio occupies the senior-operator middle: every billable hour is engineering time, pricing is published, and engagements ship in 21 to 35 days.
