Your Financial Plan Should Be a Living Document · James Vanreusel, Vanreusel Ventures

What we talked about.

In this episode of the Sunny Ray Show, host Sunny Ray talks with James Vanreusel of Vanreusel Ventures about why a financial plan should be a living document rather than a file opened only when it is time to raise money. James, who is based in San Francisco, describes his path from Wall Street and private equity to running microfinance banks in the Pacific, and how that experience shaped a firm that has operated for about 12 years. He explains the value of keeping an approved budget alongside a real time model that is updated weekly or monthly, and why cash flow and the cash out month deserve constant attention. He also covers the common mistake of staying on cash basis books until a Series A or B forces a costly switch to US GAAP accrual accounting, where AI helps and where human review still matters, who typically calls his team, and how he builds a mix of senior US based staff and overseas talent. The conversation closes with where listeners can learn more.

A budget goes stale fast. James Vanreusel explains why founders need a real time financial model and clean books long before they raise.

The questions, and the answers.

What did Wall Street and private equity teach you that founders often learn too late?

Wall Street is like drinking from a fire hose, and the standards are very high. The big lesson is that scaling requires processes and systems. In your first two years you are basically a Sherpa carrying everyone's bags, and that is true at a startup too. Early on you carry the baggage because nobody else is there to do it.

Why did you leave Wall Street for microfinance?

I grew tired of the for profit motive being the only end game and wanted to do something different, some social finance. I landed on microfinance, which gives loans mostly to women in developing countries to start businesses. Over 10 to 20 years you see generational improvement, with children staying in school, going to college and getting higher paying jobs. That was fulfilling for me.

What goes wrong when a financial plan sits in a drawer?

A budget is already stale by the end of Q1, and the variances between budget and actuals just keep growing. I tell startups to keep the approved budget but also run a second, real time model that you update every week or month. Otherwise you end up guiding the company with numbers that are simply wrong.

What does a living financial plan look like in practice?

It is usually a spreadsheet workbook built on your goals for the year, with detailed payroll and department budgets. If a hire slips from January to April, the real time model reflects it. The first tab should show your cash out month, and you check each month whether it moved later or earlier. Expenses are certain, revenues are uncertain, so stay conservative on expenses.

What is the most common financial mistake you see before a raise?

Running the books on a cash basis. By Series A, and especially Series B, investors want US GAAP accrual financials and possibly an audit or review. Early on it is normal to spend on product and sales instead of the back office, but the longer you wait, the more expensive the switch becomes, because an accountant has to go back and redo all the earlier months.

Where does AI make a finance function better, and where do you still need a human?

AI is a huge productivity boost and time saver, and it can improve quality by double checking work and catching small things. You can upload a QuickBooks export and get a board report with charts quickly. But a human always has to check the work, understand what they are looking at, and say when a number is wrong.

Who calls Vanreusel Ventures, and what are they stuck on?

Mostly VC backed companies. We stand out with international companies that struggle with consolidations, and with impact companies in climate, sustainability, food tech and health tech. We also work with hybrid for profit and nonprofit structures. Typical problems are running low on cash, accounts not ready for a raise, or internal control issues that need a closer look.
