AI-native finance · For founders
The financial model built for AI companies.
Most AI startup models don't account for inference retries, eval costs, or vector storage. That's where margins collapse.
Get an investor-ready model that accounts for every cost AI founders miss: inference, routing, reranking, storage, evals, fine-tuning, retry buffers — and the margin implications of all of it. Customized live with a CFO who's been doing this since 2007.
↑ Sample AI cost model tab — every line item has a benchmark range and a formula you understand.
📊
Full AI cost model
Inference, routing, summarization, reranking, fine-tuning, evals, storage, retry buffers. Every secondary cost — pre-built and benchmarked.
📅
60-minute live build session with Lili
You come with your numbers. We leave with a model you can defend to investors.
📈
Full P&L + cash flow analysis
Revenue model, burn, runway, and unit economics — with the AI cost layer fully integrated.
🔄
Q2 2026 benchmarks (updated quarterly)
AI costs change fast. Your model ships with current market ranges — not numbers from 18 months ago.
Who this is for
Built for three types of AI founders.
Pre-seed / Seed
Building your first model and need to show investors you've thought through unit economics — not just ARR.
Series A prep
You have revenue but your model breaks when VCs stress-test compute costs. Fix it before the next pitch.
Post-free-tier
Free API credits are running out. You need to understand real margins before costs hit — or before you raise on the wrong numbers.
What founders should expect
What you walk away with.
✓
A rebuilt AI cost stack with numbers you could actually defend.
✓
Increased runway visibility by exposing all compute cost.
✓
Improved pricing and margins due to restructuring of cost.

The CFO behind it
LB
Lili Balfour
STARTUP CFO SINCE 2007
Before running Finance for Entrepreneurs, Lili worked in tech M&A (semiconductors and software), healthcare investment banking, and at hedge fund AEOW managed by Bernard Osher and Will Weinstein. She's been building financial models for startups through multiple market cycles — including the ZIRP era and the shift to real compute economics.
Basic numbers: your current monthly revenue (or projections), your primary AI provider and rough usage volume, and your current monthly burn.
What if I'm pre-revenue?
This model is especially useful pre-revenue — that's when your unit economics assumptions matter most. We'll build on projections and make sure the assumptions are defensible.
How current are the AI cost benchmarks?
Updated quarterly. The current version reflects Q2 2026 pricing across the major inference providers.
Is this a course or a tool?
It's a working spreadsheet model plus a live advisory session — not a course. You don't watch videos. You get a model built for your company.
Why is the price $247?
This is an introductory price for the first 10 sessions. A financial model of this depth — with real AI cost benchmarks, unit economics, and a live CFO session — typically runs $2,497. We're offering it at $247 to build early case studies. Once the 10 slots are gone, the price moves up.
