Solor Stream vs a fractional CFO: what $5,000 a month buys.

A fractional CFO costs about $5,000 a month, arrives once a week, and brings judgment, relationships and a signature a bank will accept. Solor Stream costs from $49 a month and reads a founder's money, shop, books and traffic tools every night, leaving a plain-English morning briefing with its sources and how sure it is. It does not negotiate with the bank, sign the accounts or sit in the board meeting. For a business doing $5K to $500K a month, Solor Stream covers the reading nobody has time for; when the business raises a round or restructures debt, the CFO still earns the fee. Most founders will want the CFO later. The briefing is what they read until then, and what the CFO reads first when they arrive.

credit first

What a good CFO does that no software does.

A fractional CFO carries judgment. They have watched forty businesses run out of cash and can smell month nine from month four. They know the banker by name. They can restructure a loan, sit across from an investor, sign a set of accounts, and tell a founder, in person, that the plan is wrong. Some quarters that last one is worth the fee on its own.

Solor Stream does none of those. It has no relationships and no signature. It will not take the call.

the other six days

The reading happens between the visits.

The CFO comes on Thursday. The numbers they see are the ones the founder prepared, in a deck, on Wednesday night. On the Tuesday before that, three renewal charges failed at 03:14, $1,240 between them, and the deck had a slide called Risks. It was empty. Nice font.

We once paid for a weekly finance call and spent the first twenty minutes of every one rebuilding the numbers we had brought. Both sides were polite about it. Nobody said that the expensive hour was being spent on arithmetic.

Solor Stream does the arithmetic overnight. Every night, not Thursdays. It reads Stripe, checks Wise against it, opens the shop and the books, and by morning the briefing says what changed and what it means. The Thursday hour, if there is one, starts from the briefing instead of from the spreadsheet.

memory

A CFO remembers until they leave.

The record of why a decision was made lives in the CFO's head and in a folder they take with them. When the engagement ends, so does the memory of April 20 and what the numbers looked like that morning.

Solor Stream freezes the numbers the day a decision is logged and keeps them. It checks in along the way, and on the day you picked it says whether the decision worked: measured from the connected tools where it can, by asking where it cannot, never invented. Wrong calls stay on the record. Nobody takes the folder.

the honest price

$5,000 a month is $60,000 a year. So is a first hire.

For a business at $20K a month, the fee is a quarter of income. For a business at $400K a month, it is a rounding error and probably overdue. The honest line sits somewhere between, and it moves with the stage. Raising, restructuring, selling, or answering a bank: the CFO earns the fee twice. Reading the numbers every night so that nothing is a surprise on Thursday costs from $49, and it is a large part of what a founder is paying the $5,000 for.

two moves

Get the nightly reading before the CFO, not instead of them.

When the CFO arrives, their hours go to judgment rather than to rebuilding March. The briefing is the pre-read.

If you already have one, hand them the morning briefing.

The weekly hour becomes a conversation about what changed and what to do about it. The deck stops being the meeting.

straight answers

The questions founders ask about this.

Is Solor Stream a replacement for a fractional CFO?

Partly. Solor Stream covers the reading: it reads the founder's money, shop, books and traffic tools every night and writes a plain-English morning briefing, from $49 a month. It does not replace the judgment, the banking relationships, the fundraising work or the signature a fractional CFO brings for about $5,000 a month. A business raising a round or restructuring debt still needs the CFO; the briefing is what the CFO reads first.

How much does a fractional CFO cost compared with Solor Stream?

A fractional CFO runs about $5,000 a month and shows up once a week. Solor Stream starts at $49 a month, reads every night, and every account starts with a free 14-day trial, no card.
