Reventrum · The Revenue System for B2B Software & SaaS

Predictable revenue
from your
existing
deal flow.

Most software, SaaS, AI and tech companies in the DACH region invest in sales, marketing or new tools. Yet the real growth bottleneck often sits in their revenue system: in the processes, leadership and focus across the entire funnel.

Software, SaaS & tech companies DACH €1–20M ARR In-house sales team

After the first session, we decide together whether there are enough revenue levers to pursue.
If there aren't, we don't charge for the Revenue Lab.

What we do

Reventrum identifies your biggest revenue leaks, turns them into your Revenue Operating System™ and builds the foundation for reliable growth, without simply buying more leads.

How you lose revenue in your funnel today.

Even with a well-filled pipeline, too little tends to convert into predictable revenue:

  • Deals stall inside the buying center.
  • Sales teams sell features instead of business cases.
  • New GTM strategies aren't lived consistently.
  • Forecasts are gut feeling instead of reliable numbers.

The result:
Revenue potential leaks out of the funnel in several places, often six to seven figures per year.

In the Revenue Lab we expose these leaks and calculate how much additional ARR would be possible with your current setup.

„The Revenue Lab gave us the strategic clarity we had been missing. Together we sharpened our positioning, defined a clear category and built a focused roadmap for the next 90 days. Above all, it lastingly changed how we think about go-to-market and growth.“

„For the first time I had a clear picture of where my company stands today and which decisions truly matter right now. Instead of more ideas, I gained clarity, focus and a concrete roadmap for the next 90 days.“

The revenue system

From leaks to a revenue system that works.

We don't see revenue as a one-off measure, but as a system of three stages:

Start here
01

Stage 01 · Diagnosis

Revenue Lab (Diagnosis)

In three sessions we map your funnel from lead to expansion, quantify the biggest revenue leaks and build a concrete 30/60/90-day plan.

02

Stage 02 · Implementation

Revenue System Build (Implementation)

Together with your team we implement the decisive levers: structures, plays and enablement, so your Revenue Operating System™ works day to day.

03

Stage 03 · Guidance

Revenue Advisory (Guidance)

We help leadership and teams keep the new rhythm: regular revenue reviews, prioritization and sparring for founders and revenue leads.

About Reventrum

Who's behind Reventrum.

Dennis Reimann, Founder of Reventrum
Dennis Reimann Founder & Revenue Lead Has worked on predictable growth across 150+ B2B projects.

Reventrum is a specialized boutique for B2B revenue systems.

We work exclusively with software, SaaS and tech companies in the DACH region that already have deal flow and want to move their revenue from „random“ to „predictable“.

Instead of selling the next campaign or the next tool, we help revenue teams build a system that carries pipeline, win rate and expansion for years.

More about us

Fit

Who we're a good partner for, and who we're not.

A good fit if…

  • you sell B2B software, SaaS or tech in the DACH region,
  • you're roughly between €1M and €20M ARR,
  • you already have repeatable deals and an in-house sales team or clear founder-led sales,
  • you want more predictability in pipeline, win rate and expansion,
  • you're ready to genuinely work on GTM, sales and leadership, not just „a bit more activity“.

Not a fit if…

  • you're still looking for product-market fit,
  • you mainly want „more leads“, a new campaign or a tool,
  • you have no real appetite for change in your revenue system,
  • you see consulting as a report, not as joint implementation,
  • you're just looking for a quick fix for an internal political problem.

If you recognize yourself in the left column, the path always starts with the Revenue Lab.

Getting started

How you get started with Reventrum.

Every engagement begins with the Revenue Lab. Here's what getting started looks like:

Step 1

Kick off the Revenue Lab

You click „Go to the Revenue Lab“, check whether the format fits, and book a time for the kick-off call.

Step 2

3 sessions, full transparency

In three structured sessions we map your funnel, quantify your biggest revenue leaks and build a 30/60/90-day plan with clear ownership.

Step 3

Decide on Build & Advisory

Based on the plan, you decide whether we support you with the Revenue System Build and ongoing Revenue Advisory, or whether you implement the plan with your own team.

Either way, after the Revenue Lab you have clarity on your revenue levers and next steps, with no long-term commitment.

FAQ

Frequently asked questions.

Which companies is Reventrum right for?

B2B software, SaaS and tech companies in the DACH region with roughly €1M to €20M ARR, existing deal flow and an in-house sales team that want to move their revenue from „random“ to „predictable“.

Do we need to have a sales team already?

Yes. Reventrum builds on an existing revenue system. You should already have deal flow and an in-house sales team so we can quantify your revenue leaks and implement the right levers.

How does the Revenue Lab work?

In three sessions we map your funnel from lead to expansion, quantify the biggest revenue leaks and turn them into a concrete 30/60/90-day plan.

What is your guarantee?

Our guarantee: In the Revenue Lab both sides invest time and focus. That's why we share the risk:

  • In the first session we map your funnel and identify initial levers.
  • At the end of the session we decide together whether there's enough revenue potential.
  • If we don't see a clear business case, we don't charge for the Revenue Lab.

That way you only pay when we jointly identify real revenue levers.

What happens after the Lab?

For teams that want to implement the plan, there are two formats: Revenue System Build (implementing the core levers) and Revenue Advisory (ongoing guidance for your revenue team).

Revenue Lab

If revenue is going to become predictable, you need a system, not another tool.

With the Revenue Lab you get clarity on your revenue leaks and an actionable plan to close them.
