=HIRE( “fractional finance + ops, AI-native” )

I'm Erica McAfee. I was the first business hire at a YC-backed startup, and led it from seed to $10M+ ARR as Director of Ops & Finance. Now I do that work fractionally, so you can focus on growing your product.

[ A5 ]
+22%
Retention lift from a new client-success workflow I designed and rolled out.
WHY THIS MATTERS
Retention is a lagging indicator of whether your CS motion actually works. 22 points up means it did.
[ B5 ]
20×
Revenue growth I oversaw — from a couple hundred K to $10M+ ARR.
WHY THIS MATTERS
From a couple hundred K to $10M ARR. I built the finance and ops layer that made that growth manageable at each stage.
[ C5 ]
±5%
Fixed costs held within plan, every quarter. The number you want boring.
WHY THIS MATTERS
A forecast that misses by 20% isn’t a forecast. Under 5%, quarter after quarter, means the model is tracking reality.

One generalist. Two functions. Built to hand off when you're ready.

Most fractional CFOs stop at the books. Most fractional COOs stop at process. I cover both, plus the client-success layer that turns a good month into a great one.

Build the finance function, from scratch.

In-house finance & accounting, reporting, taxes, legal, IR, budgets, projections, variance. The whole stack, wired together and running on AI agents.

  • A/R and collections (hands-on)

B8 · 02

Run the bizops while you focus on product.

+

Fractional Chief of Staff / COO work. Org design, SOPs, vendor, HR, and compliance systems. Set up once, runs without you.

  • Operating rhythms + scorecards

  • People ops, payroll, compliance
  • Contract + legal ops (w/ counsel)
  • Eliminating bottlenecks, one by one
Proof → built internal bizops from scratch at a YC startup, scaled with the company thru Series B.
C8 · 03

Create the CS division before you need one.

+

SOPs, CRM, team structure, retention motions, upsell systems. The revenue work that turns existing clients into your best pipeline.

  • Client-success org + playbooks
  • CRM + handoff systems
  • Renewal + upsell motions
  • Negative-churn architecture
  • NPS + feedback loops
Proof → built and led a 7-person CS team managing $5M+ in projects; grew avg revenue per account by 33%.
SHEET 3 · METHOD =WHY.thisWorks()

Every client system runs on AI agents by default.

Monthly close, vendor follow-ups, cashflow model, board deck, CS handoffs. Built once, automated, then mostly runs itself.

B11 · ABOUT ERICA

First business hire at a YC-backed startup. Now I do that, fractionally.

As Director of Operations & Finance at a YC-backed startup, I led the company through 20× revenue growth, from a couple hundred K to over $10M ARR. Built and led a 7-person Client Success team managing $5M+ in projects, drove +22% retention and grew avg revenue per account by 33%.

I come in when founders are too early for a full-time CFO and a full-time COO, but still need both functions working. One person, both jobs, built on AI so it stays lean as you scale.

Erica was our first business hire and oversaw 20× growth, from a couple hundred K to $10M+ ARR.

A talented, easy-to-get-along-with generalist who knows how to run the bizops stuff while founders focus on growth and product. She created our Client Success division and deftly shaped the internal finance and business operations. Highly recommend.

Short essays from the seat.

I'm starting to write about the things I've learned while building out AI-native finance + ops.

First post drops Q2 2026. Topics queued: what the move to AI-native accounting actually looks like, keeping financials secure when AI handles your books.
