We Build AI-Powered Revenue Machines

L1 Advisory was built for one specific moment in a B2B company’s life — when the playbook that got the founder from zero to one stops working. Sales becomes unpredictable, GTM feels like guesswork, operations consume every hour the leadership team has. The product is good, the people are good, but something at the system level is broken.
We work with B2B founders, CEOs, and COOs on four things: the sales engine, the go-to-market, the operating system, and AI implementation inside business operations. Sometimes one, sometimes all of them — through sprints, 90-day projects, or fractional retainers. Every engagement is built around outcomes you can measure on a dashboard or a P&L. No 60-page decks, no junior hand-offs.
The fastest moving part of our work today is AI — where it replaces a hire, removes a bottleneck, or gives a team back ten hours a week. L1 helps founders see exactly where AI earns its place in their operations, and just as honestly, where it doesn’t.

FAQ
B2B founders, CEOs, and COOs at companies between roughly €1M and €20M ARR — the stage where the next phase of growth needs a system, not more effort.
Four things at the C-level: sales engines, go-to-market, operating systems, and AI implementation inside operations. Most engagements touch two or three.
We map the workflows in your business where AI can replace a hire, a tool, or a bottleneck — then we build, deploy, and train your team on the top 3. Real systems, measured in hours saved and euros recovered. Not a strategy deck.
Sometimes it removes the need for a next hire. Sometimes it gives existing people back 10 hours a week to do higher-value work. We’re upfront about which one applies to each use case before we build it.
Every AI system we build is scoped against your data policy and your stack. We use enterprise-grade tooling, document the data flows, and never train external models on your internal data.
Operators first. We’ve built and run sales engines, GTM motions, and operating systems inside companies — not just advised on them. That’s why our outputs land on a Monday morning, not in a binder.
Three formats: a 4-week diagnostic sprint, a 90-day build engagement, or a fractional retainer (typically 6–12 months, 1–2 days a week). We pick the format that matches the problem.
You get senior operators, not analysts. The output is a system your team can run, not a 60-slide deck. Engagements are measured in outcomes — conversion rates, cycle times, hours saved — not hours billed.
B2B SaaS, services, consulting, fintech, marketplaces. Mostly Europe, occasionally US. We avoid heavily regulated industries where the operating constraints we know don’t apply.
Brand strategy, performance marketing, fundraising decks, recruiting. We have people we refer to for those.
Numbers come out of the fit call once we understand the scope.
A 30-minute fit call. No deck, no pitch. Tell us what’s broken — we’ll tell you whether L1 is the right partner to fix it.
