🐶 Jacco van der Kooij

Do you know a large Midwest family? Well, if you do, then you know me.  I am the youngest of eight, raised in a small farmers'​ village in the Netherlands. If I picked an apple from the wrong tree on my way home from school, my parents would know about it before I got off my bike.

The family name is like a bank account, and my family has put their savings in it for over 50 years.  We are not rich, but the van der Kooij's are known for our hard work, and willingness to help others. So we never needed a lot of money. For my family, our reputation is the most valued asset and trust is the currency we trade in.  Every day.

Fast forward to today, a time where the subscription (SaaS) business model is impacting organizations big and small.   Why?  Because in the subscription business you MUST make a client successful!  You have to earn an honest word-of-mouth reference by exceeding a client's expectation. You have to work hard and build a reputation. I recognize this as these are the norms and values I was raised on, and I know exactly what to do.

Welcome to my village. Pop. 12,000. Established 2005.

Financial forecasting is van groot belang. Voor toonaangevende ondernemingen is een betrouwbare voorspelling een essentieel onderdeel in hun streven naar waardecreatie. Het management gebruikt deze voorspellingen om de prestaties te stimuleren, kansen en risico's te identificeren en als basis voor communicatie met stakeholders zoals aandeelhouders. Zonder betrouwbare forecasts is de kans groot dat belangrijke kansen en risico's worden gemist.

Ondanks de aantoonbare voordelen van accurate forecasts blijven veel organisaties echter worstelen met dit bedrijfskritische proces. 2ACC3L helpt je hierbij. Of je nu een start-up bent, of een bedrijf dat al tientallen jaren bestaat, of je een high-tech onderneming bent of dat het geld wordt verdiend met traditionelere producten, wij ondersteunen je bij het opstellen van een forecastmodel dat geschikt is voor jouw specifieke situatie.

Founder | Revenue forecasting & insights | Get your revenues up with RevsUp

I’ve spent over 20 years as a financial professional, building countless budgets and forecasts. But as anyone in finance knows, the struggle is real—especially when it comes to forecasting accurately and having those frustrating back-and-forth discussions with sales.

For years, Excel was my go-to tool. I’ve logged more hours in Excel than I’d care to admit. But after one too many crashes, I realized: Excel is great for many things, but financial forecasting isn’t one of them. It’s just not built for real-time collaboration, data integrity, or handling large datasets without falling apart.

That’s when the idea for RevsUp was born. I couldn’t find a tool that did what I needed—so I decided to build one. RevsUp is a user-friendly SaaS platform that helps businesses create smarter forecasts and gain actionable insights. No more endless Excel updates, no more guesswork—just accurate forecasts that help drive predictable revenue.
