"Subomi is the literal best, total icon!! I am genuinely grateful. I love partnering with a smart, hard, competent worker and he is just that! He is a great thought partner, beyond just someone to create models for you. I hired him for multiple projects and hired him additionally after I needed to redo work from someone who wasn't as thorough. He is extremely accurate, thorough, patient, helpful, willing to iterate, and does more than just create the models/chart/KPIs that you need - he helps you tell the story (both written and walking you through it) so you can understand all his assumptions. He makes projects better than what you would do on your own. Also, the work was so good that my bigwig private equity friend who reviewed his work was super impressed." 🌟 Let’s Build Something That Moves the Needle: If you need clarity from complexity, confidence in your numbers, or analytics that actually influence decisions, let’s talk.
