Run the Numbers
Run the Numbers is a twice-weekly podcast about financial metrics and business models, designed for ambitious people operating tech startups. It's a collection of things host CJ Gustafson (CFO at Partstech and writer of Mostly Metrics) has learned and thought about in the trenches as a tech CFO.
This show is meant to serve as a playbook of sorts for the stuff CJ wishes he knew earlier in his career, both from experience and from copying people smarter than himself.
Topics frequently touch upon Startup SaaS Metrics, Annual Budgeting, Financial Forecasting, Headcount, Equity, Dilution, and Fundraising – and how all of these drive business performance and growth.
