Not fractional. Foundational.

Most finance operates at arm's length. We’re in the room when strategy shifts, priorities change, and you need answers before tomorrow's board meeting. Finance is no longer a back-office function but a central nervous system of growth.

70% of what makes AI work inside a business is people and process, not algorithms. That's the part you can't install.

Our embedded teams bring the expertise, pattern recognition, and strategic instinct that only comes from working inside hundreds of companies at your stage. Finance-grade AI amplifies what our people do, freeing them to focus on the decisions that move your business forward.

Context

We understand your business logic, daily decisions, and operations because we're embedded in your work. The longer we're there, the more we anticipate.

Trust

You don't hand sensitive financial data to strangers. The relationships built over years of embedded partnership create confidence that no new tool or team can replicate.

Judgment

Our people validate every output, catch what algorithms miss, and know your business well enough to separate signal from noise in real time.

Adoption

Tools get ignored when they're not integrated into how decisions actually happen. We're in the room when it matters, so change actually sticks.

We built something fundamentally different.

The market lumps everyone together: fractional CFOs, interim controllers, contractor marketplaces. Propeller is none of these. We're foundational, trusted, and built to scale.

Not interim engagements

Integrated partnerships

We're your partner through multiple stages and exit, or we're probably not a fit. This isn't about lock-in, it's about alignment.

Not contractors

100% dedicated employees

Every Propeller professional is fully dedicated with enterprise training and security certifications. No contractors means consistent methodology and accountability.

Not single roles

Full-stack teams

We build integrated teams—CFO, FP&A, accounting, systems—that scale with your business, not individual hires you need to coordinate.

Not just people-powered

Platform-powered

Our teams work with PropellerOS, the Propeller Data Lake, and AI capabilities no solo practitioner or staffing firm can match.

ROI that compounds over time.

The value of embedded partnership shows up in the long game: deeper context, systems that have matured with the business, and a team that's been through your last four board cycles. Every month is month-to-month, because a relationship you have to enforce contractually isn't one you've earned.

Year 1

We set up your books, build your first model, and close month one before you hire employee ten.

Year 2

Your first board challenge hits. We're in the room with you, adjusting the plan in real time and keeping investors aligned.

Year 3

Multi-entity accounting, trade spend optimization, and institutional reporting become routine—we've scaled hundreds of companies through this stage.

Year 4

We spot issues before they surface. The depth of context we've built creates advantages no new partner could replicate.

Year 5

Due diligence populates in days because we built for this moment. We stay through the transition and beyond.

FAQs

Questions your board will ask.

Propeller works with venture- and growth-stage companies, typically in the $3M–$300M+ revenue range, with teams that flex up or down as you scale. 

Engagements run month-to-month. We don't use long-term contracts, because a relationship we have to enforce contractually isn't one we've earned: we'd rather be worth keeping every month than be difficult to leave. What we do look for is the potential for a multi-year partnership. 

If what you need is a three-month solution, we'll point you toward a good fractional firm instead. That's not a brush-off; it's the honest answer, and it's why many clients stay with us for years.

AI can accelerate bookkeeping, but it can't yet run it unsupervised. The clearest evidence is how the AI companies themselves ship it: the finance agents built by the leading labs stage every output for human review before it goes anywhere. That isn't caution about an immature product; it's an acknowledgement that a close, a filing, or a number headed for a board needs someone who can answer for it. Propeller's teams use finance-grade AI to handle data aggregation and pattern recognition, and every output is validated by people who know your business well enough to catch what the algorithm misses.

Context is what lets a finance team anticipate a problem instead of just reporting it after the fact. A CFO who's been in the room for your last three board meetings will catch a cash flow issue before it becomes a crisis; a new hire reading last quarter's reports won't. Propeller's embedded model is built around this: the longer we work inside a company, the more we understand its business logic, its decision patterns, and its blind spots — which is why context, not headcount, is the real asset.

The moment you ask this question you likely need more than a single hire can provide. Propeller provides an embedded CFO, FP&A, controllership, and accounting support working together, typically running 20-35% less expensive than a full-time CFO hire alone. Instead of choosing between "not yet" and "one very expensive person," you get the full function at the stage where you actually need it, and years before a solo hire would make financial sense.

Propeller works with venture- and growth-stage companies from seed through exit, typically in the $5M–$300M+ revenue range, with teams that flex up or down as you scale. Engagements run month-to-month rather than requiring a fixed minimum term, so the team you start with at Series A isn't the team you're stuck with at Series C.
