Competitor Comparison
StartupCFO vs. airCFO
airCFO offers accounting, finance, tax, and People Ops as separate lines across four stage tiers, backed by its own AI. StartupCFO bundles books, tax and CFO support into one plan, with ClariFi's agents working read-only on your data: deterministic code calculates every figure, each one cites its source, and our accountants and CFOs sign off. Here's how they compare.

airCFO figures are the published starting points on aircfo.com/pricing as of August 2026. Their tiers gate on capital raised, monthly revenue, and monthly expenses, and each service line is quoted separately, so an actual engagement depends on which lines you buy. Founders should confirm current pricing directly.
Four line items or one plan?

What airCFO Does Well
airCFO has built a serious startup finance practice. Here's what they bring to the table.
They report serving 520+ startups and build only for startups, so the team has seen the specific problems that show up between a seed round and a Series B.
People Ops is a real differentiator. Very few startup finance firms offer HR advisory as a first-class service line, and buying finance and HR from one firm removes a coordination problem.
Their stage tiers are honest about who each level is for. Gating on capital raised, revenue, and expenses tells you plainly which tier you belong in before you talk to anyone.
They committed to pairing people with software early, and now position as an AI-enabled back office rather than treating software as an afterthought.
Where StartupCFO Is Different
Both firms serve startups well. Here's where our approaches diverge.
One Plan, Not Four Line Items
airCFO prices Accounting, Finance, Tax, and People Ops as separate lines at every tier. At the Launch tier that is $1,600/mo for accounting, another $1,600/mo for eight hours of finance advisory, and tax from $2,400/year on top. StartupCFO bundles the bookkeeper, CPA, and 50% off tax prep into one number from $199/mo, so the price you see is the price of a working finance function.
Not Gated on What You Have Raised
airCFO's tiers key off capital raised, revenue, and monthly expenses, and the earliest tier bills finance work hourly at $400/hour rather than retaining a CFO. StartupCFO prices on what you need: Foundation at $349/mo includes CFO support as needed and Growth at $799/mo includes a full fractional CFO, whether you have raised $40M or nothing at all.
Tax Is Not a Separate Purchase
airCFO publishes tax from $2,400/year as its own line, rising with stage. Every StartupCFO plan includes a 50% discount on tax prep, 1 state + 1 federal return, with obligations tracked across all 50 states. Compliance is not something you remember to buy in the spring.
ClariFi Shows Its Work
Both firms pair people with software. ClariFi's difference is verifiability: every AI-generated number carries a validated citation back to your own data as a clickable source chip, and agents propose while deterministic calculations compute, with human approval before anything counts. On Growth you get direct dashboard and MCP access, so you can interrogate the numbers yourself rather than wait for a reporting cycle.
Live in 2 Business Days
Matching to a tier and assembling the right combination of service lines takes a scoping conversation. StartupCFO starts with a 30-minute kickoff call and has your finance team live within 2 business days, with 50% off tax prep from the first tier.

Frequently Asked Questions
How is StartupCFO different from airCFO?
Both are startup-native finance firms with a hybrid of people and software. airCFO prices four service lines separately (Accounting, Finance, Tax, People Ops) across four stage tiers gated on how much you have raised. StartupCFO bundles a bookkeeper, CPA, and 50% off tax prep into one plan from $199/mo, and adds a full fractional CFO plus direct ClariFi access on the Growth plan at $799/mo.
Is StartupCFO cheaper than airCFO?
On a bundled basis, yes. airCFO's published starting points at the Launch tier are $1,600/mo for accounting and $1,600/mo for eight hours of finance advisory, with tax a separate line from $2,400/year, so accounting plus finance plus tax starts near $3,400/mo. StartupCFO's Growth plan is $799/mo for a full fractional CFO and bookkeeping, plus a 50% discount on 1 state + 1 federal tax prep. On hours, be precise rather than taking our word for it: Growth carries a fair-use allowance of about 3 hours of CFO time a month against airCFO's eight. Fewer hours, and deliberately so: the board pack, the model, the cap table and the fundraising support all land inside them, because bookkeeping, tax and ClariFi have already taken the assembly work off the CFO's plate. You are buying the judgement, not the hours spent pulling the numbers together. If what you want is a high monthly volume of advisory hours as such, price both on hours; if what you want is a finance function, the bundles are not close.
Can I get a fractional CFO from airCFO before my Series A?
At airCFO's Launchpad tier, for companies with under $4M raised, finance work is billed hourly starting at $400/hour rather than retained, and retained advisory begins at the Launch tier from $1,600/mo. StartupCFO includes CFO support in Foundation at $349/mo (about 1 hour a month) and a full fractional CFO in Growth at $799/mo (about 3 hours a month), with no gate on how much you have raised. Beyond the allowance we agree a footing with you first, hourly starting at $300/hour.
Does airCFO do anything StartupCFO does not?
Yes. airCFO offers a dedicated People Ops line covering HR advisory, which StartupCFO does not provide. If you want your HR function and your finance function bought from the same firm, that is a genuine reason to choose them. We run payroll as a $50 per W-2 employee monthly add-on on Foundation and Growth, but do not offer HR advisory.

The part few others have
Ask your own AI about your own financials
ClariFi ships an MCP (Model Context Protocol) server, so you can connect your finances directly to Claude and ask questions in your own words, in the tool you already work in. Not an export. Not a dashboard you have to visit. Your KPIs, runway, budget versus actuals, unit economics, and cap table, available to the assistant you already use. airCFO does not offer this, and few startup-accounting firms do.
Connects in a click
OAuth 2.1 means the claude.ai connector attaches directly. No scripts, no key wrangling, no engineer required.
Answers, not exports
“What’s my runway if I hire three engineers in Q3?” answered against your live books, while you are still in the conversation.
Approval-gated, scoped to you
Your assistant can read your numbers and propose an update, but nothing applies until someone approves it in ClariFi. Every session is scoped to your company, and it never touches your books.
