About

My OpenSource projects:- Clay automation agent: https://github.com/leszek-backpack/rexI help B2B revenue teams turn scattered AI usage into GTM systems they own.Most teams I work with are past the "should we use AI" question. A founder runs research through Claude. A sales op pastes account notes into ChatGPT. A marketer pulls angles, someone automates Clay. The context lives in one person's head and dies when they're on PTO. The workflow changes every run. Quality control happens late, after the mistake.The work I do is the operating layer that turns that mess into something the team runs end to end. I map the GTM workflow with the team, build the agents and deterministic steps around it, install context the agents can use, add human QA on the important 10-20%, and hand it back as a system the team owns.A six-week build sprint is usually the right shape. The team leaves with reusable agents, workflow docs, review habits, and the foundation to extend the system without me.Where the work shows up most: signal and intent pipelines, outbound and ABM execution, account intelligence and buyer mapping, interactive sales assets, marketing and content operations, customer success workflows, and the agent infrastructure underneath all of it.The point is a revenue team that builds, reviews, and ships faster than it could six months ago.If you have one messy GTM workflow that still lives in prompts, tabs, and manual handoffs - that's where to start.lammel.ai
