Bart Davis of 512Financial: Why Founders' First Two Hires Should Be a Controller and HR Lead

Frequently Asked Questions

What is Bart Davis's rule for how much a startup should spend on accounting and finance?

Davis tells McKenzie that his firm typically sees clients spending 2 to 4 percent of top-line revenue on the accounting and finance function, depending on complexity and transaction volumes. He illustrates the point with a $15 million client spending roughly $250,000 annually, noting that while the absolute number sounds large, it actually falls at the inexpensive end of his rule.

Why does Davis argue a Fortune 500 CFO is often the wrong hire for a startup?

Davis says there is a misconception that bigger-company pedigree equals better fit. He argues the skills required to scale a business from roughly $1 million to $5, $10, or $15 million in revenue are fundamentally different from those of a Global 1000 CFO, and that investors and operators who recognize this disparity tend to see better outcomes.

What was the strategic thesis behind 512 Financial's acquisitions of Austin PeopleWorks and HireBetter.com?

Davis frames both 2025 acquisitions as a way to extend customer lifecycle and 'monetize churn.' Austin PeopleWorks expanded the firm's people-ops capacity, while HireBetter's retained executive search practice lets 512 place the full-time CFOs, controllers, and HR leaders its fractional clients eventually need, rather than waving goodbye when a client outgrows the fractional model.

Which two hires does Davis say founders typically get wrong before an exit?

Davis points to his co-founder Joel Trammell's counterintuitive playbook: after raising significant capital, Trammell's first two hires were a controller and an HR leader, before product or go-to-market roles. Davis argues most founders reverse that order, underinvesting in the back office and creating messy books and compliance gaps that damage valuation when an exit finally arrives.

How does Davis view AI's role in replacing CFO work?

Davis says his team uses AI every day but has inherited Claude-built financial models 'riddled with errors' that only a trained CFO would catch. He applies an 80/20 rule: humans should do the 20 percent of work driving 80 percent of the value, while AI handles the 80 percent of work that only drives 20 percent.

Why does 512Financial hire its fractional talent as W-2 employees rather than 1099 contractors?

Davis says the W-2 model protects clients from misclassification risk because they engage a company rather than an individual. It also lets accountants, finance, and HR professionals focus on their craft without worrying about where their next check comes from when a client rolls off after hiring full-time internally.
