# Joel Sandstrom, Engineering Lead at Fieldpath (38 people, B2B SaaS) — read of Claude Prompt Meter, June 22 2026

> 9 years in product engineering, currently the person who opens the Anthropic invoice every month and has to explain it to the CFO.

## How I got here

Got an unexpected Claude API bill two weeks ago. Opened a ticket with myself to find a better way to track per-session spend during dev, not just by month in the dashboard. Googled "claude api token cost before sending." This came up on page two. I clicked because the headline was direct.

## What I clicked first

"Stop burning tokens without seeing them" landed immediately. That is the exact sentence I would have typed to describe my problem. And the feature list below it was clear: per-prompt cost, session cumulative, model comparison sidebar. I was maybe 20 seconds from clicking install.

Then I noticed this is not actually a product page for a shipping product. It is a sales page for an idea package. The install button says "Install from Marketplace" but the real CTA is "Unlock the dossier $5."

## Where I paused

The scoring section. "$-14,046 Year-1 take-home (Fermi)" is a negative number. The site voluntarily tells me this idea loses money in year one on their own estimate. And then right below that: "Honest disclosure: we don't have live customers on this idea yet." I have never seen a product page do this. I stopped and read it twice.

## What I distrusted

The frame switch confused me. The first half of the page reads like a product I can use. The second half reveals it is a product I am supposed to build. That is a jarring pivot and I almost closed the tab because I felt misled, even though the information was technically there. "Strongest axes: buyer clarity 10/10" is also a strange thing to brag about when I had to re-read the page to understand what I was actually being sold.

Also the self-score says "landing page quality: 2/10" which is either honest or a hedge, and I genuinely cannot tell which.

## What would convince me

If there was one real person who bought the $99 dossier and described what they got in 3 sentences, I would take the $5 unlock seriously. Not a testimonial with a headshot. A paragraph-length Slack message or email quote with their first name and what they actually shipped. The Fermi math is interesting but a Fermi estimate from the seller is still a seller estimate.

## What I'd ask in an email reply

1. The "Install from Marketplace" button implies something already exists. Does it? Is there a working VS Code extension I can try right now, or is the code in the $99 tier the first working version?
2. The $-14K year-one figure, what assumptions drive that? Is that assuming paid solo dev time, or just raw revenue minus costs?
3. You score "financial upside: 1/10." That is a brutal self-assessment on a tool you are charging $99 for. What is the case for buying it anyway?

## Verdict: on-the-fence

The honesty on this page is unusual enough that I have not closed the tab. But I came here looking for a tool I could install today, and what I found is a research kit for someone who wants to build one.
