In this episode of The ModSquad, hosts Paul Barnhurst, Ian Schnoor, and Giles Male welcome Tim Jacks, founder of Taglo, for an insightful discussion on the integration of AI in financial modeling. Tim’s expertise bridges the worlds of financial modeling and AI, and in this episode, he shares his journey and discusses how AI is reshaping the financial modeling landscape.

Tim Jacks is the founder of Taglo, a company dedicated to improving financial modeling with AI technology. His career journey spans financial consulting and software development, including building financial modeling tools. Over time, Tim's interest in artificial intelligence grew, and he delved into how AI, particularly Large Language Models (LLMs), could be used to enhance financial modeling processes.

Expect to Learn

1. How AI is revolutionizing financial modeling and the specific ways it’s being used today.
2. The technical components behind AI agents and how they differ from simple chatbots.
3. The importance of context and system prompts when working with LLMs in financial tasks.
4. Insights into the memory limitations of LLMs and how agents work around this challenge.

Here are a few quotes from the episode:

1. "If you're using AI for Excel modeling, you need to remind it to follow good financial modeling principles, like the FAST Standard." – Tim Jacks
2. "The beauty of LLMs is that you can go back and change the conversation, they're stateless, so it's like resetting the clock." – Tim Jacks

Tim Jacks provided valuable insights into the integration of AI in financial modeling, particularly how LLMs and agents are transforming workflows. While AI can significantly enhance efficiency, human expertise remains essential for applying financial modeling principles.

In this episode of The Mod Squad, hosts Paul Barnhurst, Ian Schnoor, and Giles Male continue their hands-on testing of AI tools for financial modeling. This time, they put Subset, an AI-powered spreadsheet tool still in beta, through its paces. The hosts explore whether Subset can realistically handle core financial modeling tasks, including importing Excel files, building three-statement models, and applying basic accounting logic. Along the way, they uncover significant limitations, bugs, and logical errors that highlight the risks of relying on unsupported or immature tools.

Expect to Learn

• What Subset promises to do and how it performs in real-world testing
• The challenges of importing Excel files into non-Excel environments
• Why basic accounting logic still breaks many AI modeling tools
• The risks of using outdated or unsupported AI tools found online
• What it would actually take for professionals to move away from Excel

Here are a few quotes from the episode:

• “There’s no AI on the planet that should tell you gross profit is revenue plus costs.” – Ian Schnoor
• “It’s clever, but massively flawed and unreliable in lots of areas right now.” – Giles Male

Subset shows ambition in trying to act as a full AI spreadsheet, but the testing reveals serious issues, from incorrect formulas to flawed financial logic and unstable performance. While the tool demonstrates how far AI experimentation has come, it also serves as a cautionary example of why finance professionals must validate outputs and maintain strong technical foundations.

In this episode of The Mod Squad, hosts Paul Barnhurst, Ian Schnoor, and Giles Male continue their exploration of tools for financial modeling. This time, they test Melder, a tool designed to streamline financial modeling tasks in Excel. The hosts evaluate how it handles various financial exercises, such as creating formulas and generating a deferred revenue schedule. While the tool shows promise, the hosts identify areas where Melder has room to improve, particularly with bugs and user experience quirks. This episode also highlights the challenges of using tools still in beta.

Expect to Learn

• A detailed review of Melder’s features for Excel-based financial modeling.
• How Melder compares to other tools previously tested by the team.
• Challenges faced when using Melder for tasks like building formulas and financial schedules.
• The pros and cons of using Melder, especially when it comes to its unique features and limitations.
• Insights into tools’ development process, especially when still in beta.

Here are a few quotes from the episode:

• "I appreciate the confidence behind the bold statements, but at the end of the day, tools need to make sure they’re doing the job correctly." – Ian Schnoor
• "When tools go wrong, it’s not just about fixing the error; it’s about understanding what went wrong so we can avoid future issues." – Giles Male

Melder offers some useful features for financial modeling, such as custom formulas and file handling, but it still faces challenges like data overwriting and slow performance. While it shows potential, especially in automating tasks, it needs further refinement to become a reliable tool for complex financial tasks. As it continues to evolve, we look forward to seeing how it improves and addresses these issues.
