What Actually Lands in Your Function Friday Inbox

Stories from the Trenches

Get the real deal on startup finance—like why we celebrated offboarding a client (hint: it meant we did our job right), or how a $12M SaaS company's revenue recognition error delayed their fundraise by six months. These aren't sanitized case studies; they're honest looks at what it takes to build businesses that last, mistakes included.

The Metrics That Actually Matter

Skip the vanity metrics and focus on what investors and operators really care about. We break down concepts like the Rule of 40, why post-money SAFEs now dominate 82% of the market, and how to separate revenue growth from actual business health. You'll get the context behind the numbers—so you can make decisions, not just track data.

Systems That Scale With You

Every issue includes frameworks you can actually implement. Whether it's setting up weekly cash flow forecasts, understanding what great bookkeeping should include, or building dashboards that drive decisions (not just look pretty)—you'll get practical guidance for building financial operations that work.

Finance Made Human

Complex concepts explained without the MBA jargon. We take topics like cash flow management, audit preparation, and investor readiness and make them accessible for founders who need clarity, not complexity. Because the goal isn't just understanding your numbers—it's using them to build something meaningful.

Function Friday gives me practical insights I can actually use. Their approach to cash flow and financial planning helps me make better business decisions.

— Mike Schatzman, Founder and Managing Partner, Venture Forward Capital

I refer portfolio companies to Function all the time because their insights are exactly what growing businesses need. Function Friday shows why their approach works—it's practical, not theoretical.

— Janine Kick, Partner, Kerosene

The behind-the-scenes client stories are gold. Josh's breakdown of SAFE trends and market shifts gives us insights we can't get anywhere else—and it's all actionable.

— Tommy Lather, Founder & CEO, Takeoff Monkey
