#91 Building Financial Models in Excel with Giles Male and Myles Arnott, Founders at Full Stack Modeller

Giles Male and Myles Arnott, co-founders at Full Stack Modeller join Kevin Appleby on the GrowCFO Show to discuss how to build financial modeling in Excel.

One of the biggest challenges of financial modelling is creating models that are accurate and realistic. Financial modellers need to have a good understanding of all of the different formulas and functions in order to create an accurate model. Many people, even experienced modellers, use less than 5% of the functions available. Excel models need to be properly structured too so that others can easily validate them, and they can be checked for errors. There are lots to learn about, and many tips and tricks that can make your life much easier. That’s why Myles Arnott and Giles Male set up Full Stack Modeller.

In this episode, Kevin Appleby chats to Miles and Giles to discover more about the challenges of building great financial models in Excel and how the Full Stack Modeller training and community of members can help you.
