"I wouldn't look any further than GRAY for a forecast model. The structure and sophistication was exactly what investors were looking for when evaluating our business. It wasn't just the model though. Joe's input was also extremely helpful during the fundraising process.”

What our clients say

"We came to GRAY at a critical juncture. What Joe was able to put together in a short period of time was nothing short of exceptional. Not only did the financial model completely realign our strategy, it presented as a seamless companion document and feedback loop for the pitch deck and brand itself. We would strongly recommend GRAY to anyone attempting to navigate the challenging and choppy waters of venture capital."

What our clients say

"We needed someone to help us develop our forecasts for our startup and Joe came highly recommended. Joe really took the time to understand our business and how our specific revenue model works. He developed us a sophisticated model that we could both use with our investors for our pre-Seed fundraise but also, importantly, for us to use on an operational level to track our spend and cash going forward. I would recommend GRAY to any startup needing a professional model for fundraising and operations."

What our clients say

“Joe was a pleasure to work with and built a fully-integrated three statement forecast model very efficiently. The modelling was high quality, reliable and flexible, which made it easy for us and the management team to adopt it. Joe, and the team at Gray, were a key part of all parties reaching a successful outcome. I wouldn’t hesitate to recommend Gray’s services.”

What our clients say

"Joe was outstanding to work with. The concept of the fully integrated model for investment was a difficult problem to solve - with multiple areas of the business we know so well having to be forecasted out with detail we hadn't previously explored. Joe worked with the thought and process of a vast organisation but with the speed and nimbleness of a small one. He quickly became a critical part of the team. A BIG thank you for your brilliant work on our growth model.”

What our clients say

"'To prepare for our late-stage seed round, Joe took our existing financial model and upgraded it on multiple fronts, including a much-improved sensitivity analysis and a complex earnings predictor that took into account multiple revenue streams. He was the ultimate professional to work with and I have no hesitation in strongly recommending his services."

What our clients say

"Most start-ups find it challenging to create a strong financial model due to its complexity, and our company was no different. Despite my background as a data analyst and creating a decent model, it lacked clarity. Luckily, Joe was able to assist us by restructuring the data in an appealing and easy-to-read format. He grasped our business model quickly and was very friendly and easy to talk to. I strongly recommend Joe to anyone seeking assistance with their financial model. Thank you Joe!"
