SaaS Finance Lab — Founding Cohort

Why this exists

Your last ARR bridge is in someone's Downloads folder.

Every SaaS finance team rebuilds the same four or five models a year. The runway model broke when hiring changed. NRR ties to one number in the board deck and a different one in the dashboard. Nobody can remember why.

01

Template graveyards

You've downloaded thirty free SaaS templates. None of them survived contact with your actual billing data, and now you don't trust any of them.

02

Models nobody can audit

Locked tabs, hard-coded cells, assumptions buried three sheets deep. When an investor asks how a number was derived, you're guessing.

03

Learning it alone

No one to check the logic, no one to tell you the approach you picked will fall apart at the next fundraise.

Who it's built for

Three people get the most out of this.

Heads of finance & FP&A leads

At $5–100M ARR, where the spreadsheet stack has outgrown the person who built it and the board has started asking harder questions.

Founders doing their own finance

No finance hire yet, a raise on the horizon, and a growing suspicion that your model wouldn't survive diligence.

Fractional CFOs & consultants

You build the same models for every client. Build them once, properly, and stop charging your clients for the rebuild.

The calendar

A delivery schedule, not a curriculum.

Nothing to fall behind on and no modules to complete. One model and one session a month, on a fixed date.

01 · Sep

ARR bridge

New, expansion, contraction, churn — and why your bridge never ties to the P&L.

02 · Oct

Burn multiple & runway

Scenario-driven, with the hiring plan as an input rather than an afterthought.

03 · Nov

Usage-based pricing model

Forecasting revenue when the customer decides the size of the invoice.

04 · Dec

Board pack

The fifteen slides that answer the questions before they get asked.

05 · Jan

Cohort retention & NRR

Built from raw invoice data, not a dashboard export you can't audit.

06 · Feb

Annual operating plan

Top-down and bottom-up, reconciled, with variance logic built in.

You vote in month five, I build. Founding members decide the back half of the year.

Who's running it

I build these models anyway.

Aleksandar Stojanovic, founder of Fiscallion

Ten years in FP&A, BI and accounting — ABBYY, Coca-Cola HBC, and Usercentrics through its climb to €100M ARR — then fifty-odd SaaS companies through Fiscallion, where I'm the one actually in the model rather than a junior.

The same four or five models come up in every engagement and I rebuild them each time. The Lab is me building them once, properly, in the open. The founding thirty get half price because you're first, and being first means the calendar isn't perfect yet.

Client stories

The same models, from the client side.

“They untangled our finances and built a model that brought clarity to our entire business. I highly recommend them.”
Predrag MandlbaumFounder, More Screens

“With Aleksandar's financial model, we raised funding with confidence and clarity.”
Djordje JevticFounder, OtaSync · $1M+ raised

“I was impressed by the quality of the financial model and the level of automation built in. It's been a game-changer for how we run our SaaS business.”
Bojan RadojicicFounder, Time Analytics

The guarantee

If the first session doesn't run, nobody has to ask for a refund.

You're buying something that doesn't exist yet, from a cohort that hasn't filled yet. So the risk sits with me: if the first session doesn't happen on schedule, I refund all thirty seats without anyone having to email me.

Expense it

Most members won't pay for this themselves.

At $490 it sits well under most professional development budgets, and you'll get a proper invoice at checkout. Enter your company's EU VAT number and VAT is reverse-charged. Here's a note you can forward:

Subject: Professional development request — SaaS Finance Lab

Hi [Name],

I'd like to join the SaaS Finance Lab, a twelve-month programme run by Aleksandar Stojanovic of Fiscallion. Each month it delivers a finished SaaS financial model and a live build session — ARR bridges, burn multiple and runway, usage-based pricing, board packs, NRR, and the annual operating plan.

Practically, it means I'd bring back working models for [name one or two things your team currently rebuilds by hand] rather than building them from scratch. He was on the finance team at Usercentrics through its climb to €100M ARR and has modelled $100M+ across 50+ SaaS companies.

It's $490 for twelve months and a corporate invoice is provided. Could this come out of the professional development budget?

Thanks,
[Your name]

Questions

Answered.

Can my company pay for this?

Yes, and most do. A proper invoice is generated at checkout. If your company has an EU VAT number, enter it and VAT is reverse-charged.

What if I can't make the live sessions?

Every session is recorded and posted the same day, and the model lands in the Lab whether you attend or not.

Excel or Google Sheets?

Both. Every model ships as an .xlsx and a Sheets copy with identical formulas.

Is this the same as hiring Fiscallion?

No. The Lab gives you the models and the method. A Fiscallion retainer is me inside your numbers every month. Members who want that get a call first.

What if my company is pre-revenue?

Then this isn't for you yet — the models assume you have billing data to put through them. Come back after your first year of real revenue.

What happens after twelve months?

You renew at $490 or you don't. Founding members keep that price for as long as they stay, and I email a month before it's due. No auto-renew surprises.

Stop rebuilding the same SaaS models every quarter.
