The Problem

Why most B2B sales systems fail.

You don't have a lead problem. You have a system problem. Tools don't talk. Data is dirty. Reps run their own playbook. The forecast is a guess.

01 Reps follow gut, not a playbook 73% miss quota
02 CRM is a graveyard of stale records ~40% data decay/yr
03 AI tools layered, not integrated 5–9 disconnected apps
04 Forecasts are political, not predictive >60%

How It Works

Think → Build → Run. End to end.

One methodology. Three modes. Engineered to compound.

Diagnose what's actually broken.

We don't start with tools. We start with truth. A 2–4 week diagnostic across pipeline, CRM, GTM, and team, surfacing the real constraints before any build begins.

  • ICP & segmentation refresh
  • Sales math & capacity model
  • GTM motion & positioning audit
  • Diagnostic report & roadmap

Engineer the engine.

We architect and ship the infrastructure: CRM, data layer, AI workflows, playbooks, dashboards. Productized where it makes sense, bespoke where it matters.

  • CRM architecture & integrations
  • AI workflows & orchestration
  • Data hygiene & enrichment
  • Cadences, playbooks, enablement

Operate. Optimize. Compound.

We run the system with you, weekly rituals, monthly forecasting, quarterly tuning and train your team until they own the engine end to end.

  • Weekly pipeline reviews
  • Forecasting & capacity tuning
  • Quarterly system optimization
  • Team training & hand-off

Operators trust us. Numbers back them up.

We've shipped systems across SaaS, FinTech, Industrial and Services teams in 11 European markets.

"We replaced three agencies and four tools with one system. Pipeline coverage went from 1.4× to 3.8× in one quarter — and the forecast finally matches reality."

Honest filter

This is not for you if…

We'd rather lose the deal than waste your quarter. If any of these are true, we're not the right partner, and we'll tell you.

  • You are not ready to change how you sell.
  • You expect hacks or "magic" leads.
  • Your product is not validated yet.
  • You don't have a sales motion (or aren't planning to build one).
  • You're looking for outsourcing, not a partner.

Questions you're probably asking.

What is a Revenue Operating System?
A Revenue Operating System (also known as Revenue OS or RevOps architecture) is one connected system for how a B2B company generates, qualifies and closes pipeline. It links GTM strategy, sales process, CRM, data and execution into a single operating model, instead of leaving them as disconnected parts that each leak revenue. The result is commercial growth that is predictable and repeatable, not dependent on luck or on the founder chasing every deal.
Who is GrowthOS for?
GrowthOS is built for B2B companies with real commercial complexity: long sales cycles, considered purchases, and several stakeholders involved in each decision. We work with founder-led and mid-market B2B companies looking to grow in different ways: building a predictable sales pipeline that no longer depends on the founder, expanding into new international markets, entering new segments within the markets they already serve, or structuring outreach for a specific objective such as raising capital. If you sell something meaningful to other businesses and want commercial growth that is structured rather than reactive, there is a way in for you.
How does it work?
GrowthOS runs on a three-phase methodolog: Think, Build and Run. Three phases, one engine. Think is the diagnosis and strategy phase: who to sell to, with what message, through which process. Build stands up the operating platform and the sales infrastructure behind it. Run is the ongoing execution: outbound prospecting, sales operations, and qualified meetings landing in your pipeline. Think comes first because it is what makes everything after it pay off. You can engage one phase or the full engine, but we do not run execution on top of an unclear strategy, because that just scales the problem.
Do you replace our existing stack or work with what we have?
We work with your existing CRM and sales stack. Salesforce, HubSpot, Microsoft Dynamics, Pipedrive, Zoho and the tools around them stay in place. We add the operating layer that makes them work as one connected system, and bring in our own platform where a capability is missing. We only touch a stack component when it is actively holding the system back, and only with your sign-off. The goal is one integrated system that works, not a migration project.
How fast can we see real results?
Timelines depend on which entry point you choose. Our Growth Tools are the fastest: focused assessments and generators that give you concrete commercial output in the same working session, useful on their own and a low-commitment way to see how we think. The full engine compounds over time. Think delivers commercial clarity within the first weeks: a clear target account list, the right message for each segment, and a defined sales process. Build stands up the platform after that. Measurable pipeline lift typically shows from the following quarter onward, as execution compounds. We do not sell overnight transformation. We build a system that gets stronger every quarter it runs.
What does an engagement typically cost?
Engagement cost depends on which phase you engage and is always shared openly before any commitment. Growth Tools are low-cost or free entry points. Think is a fixed-scope strategic engagement. The GrowthOS platform comes at no cost while we work together. Run is a monthly operated service, priced to the scope of execution you need, often with a variable component tied to results. You always know what you are paying for and why, and the first conversation gives you a clear scope before anything is signed.
How is GrowthOS different from a consultancy or an agency?
GrowthOS is structurally different from a consultancy or an agency. A traditional consultancy hands you a deck and leaves. A sales agency hands you outsourced execution with no strategy behind it. GrowthOS gives you an operated system where strategy, infrastructure and execution are one layer instead of three disconnected ones, backed by operators who have built and run commercial systems across multiple B2B markets, not advisors working from theory. We bring our own platform and proprietary data to build your target account lists and reach the right buyers, so execution starts from real ground rather than a blank page. Everything lives in your systems and your team owns it. If we part ways, you keep everything built up to that point and keep running it. No lock-in on your data, your code or your process.
What happens if we want to part ways mid-engagement?
Every deliverable is documented and handed over as we go. Diagnostics, blueprints, configurations and dashboards live in your systems, not ours. If we part ways, you keep everything built up to that point and your team can continue running it. We do not lock data, code or processes behind us, and Sales Engine engagements have clean exit clauses at the end of each phase.
