# Jake Rhinehart, Technical Co-founder (between ventures) at Rhinehart Labs — read of AnnounceBar Pro, 2026-06-13

> 12 years building software, sold a $150K ARR SaaS to a private buyer in 2024, currently consulting two days a week and shopping for my next thing.

## How I got here

Somebody in my ex-founders Slack dropped a tweet from Wishdeal saying they "publish Fermi math on their own ideas including the bad news." That framing got me. I clicked through expecting the usual startup theater. I have two kids under five and ninety-minute coding windows after bedtime, so I do not have time for ideas that dress themselves up. I was specifically looking at micro-SaaS businesses with existing demand signals I could validate cheaply.

## What I clicked first

The pricing header. "$2.99/month" is a real number, not "starts at" with an asterisk. That pattern usually means the builder has made a specific call rather than pricing-by-committee. I respect the discipline even if I'm not sure the number works.

Then I hit the feature list. "Real Support. Humans answer emails the same day. Real names. Real expertise. No chatbots, no ticket queues." Okay. That's a positioning choice, not a feature. Someone thought about it.

## Where I paused

The honest scoring block. "66/100 Adoptability. $-9,108 Year-1 take-home (Fermi). 1 in 8 meaningful-success odds."

I sat there for a while. That is a bold thing to publish on your own product page. Financial upside: 1/10 is not a soft disclosure buried in a footnote. They scored their own idea one out of ten on financial upside. I have never seen a marketplace do that. It is either a genuine attempt at intellectual honesty or a very clever trust-building move. Maybe both. I do not know which, but I read it twice.

## What I distrusted

The social proof block directly contradicts the honest disclosure, and that is a real problem.

"8,000+ e-commerce stores trust AnnounceBar for their announcements and popups. 16 months of proven product-market fit."

Then, maybe three scrolls later: "Honest disclosure: we don't have live customers on this idea yet."

Those two things cannot both be true. The first reads like customer data. The second says there are no customers. I have to assume the 8,000 number is either a comp analysis they dressed up as social proof, or it is copy they wrote for the hypothetical product as part of the "brand package" you'd receive if you buy. Either way, publishing it above the fold in a "Why Founders Love AnnounceBar" header is misleading. A buyer who reads quickly and skips the scoring section walks away thinking this tool has 8,000 users. It does not. That gap is doing real damage to trust, and it is exactly the kind of thing that makes me wonder what else on this page I should discount.

## What would convince me

The Fermi math is interesting but I do not know the inputs. I would want to see the actual model: customer acquisition cost assumed, churn rate assumed, conversion rate from free trial assumed. Not the output. The math. Anyone can produce a plausible-looking Fermi estimate. Show me the cell references.

Also: one real conversation. Not a case study. Not a testimonial. A description of a call with one store owner where Wishdeal asked about their current tool, what they pay, what they hate about it, and what they said. Five sentences. That would do more than any score.

And fix the 8,000 stores claim or remove it. If that is a market sizing number, say "8,000+ stores currently use tools like this." If it is a comp's user count, cite the comp. Do not let it float there looking like customers you do not have.

## What I'd ask in an email reply

1. The page sells me on the idea but I can't tell if I'm buying a product or a research package. If I pay $99, what code do I actually receive and in what stack? Can I see the repo structure before buying?

2. The 8,000 stores number and the "no live customers" disclosure are in direct conflict. Which is accurate and what is the 8,000 actually measuring?

3. Pain intensity is 4/10. You scored it yourselves. That is a meaningful signal about whether store owners will pay to switch. What is your read on why the pain is low, and what would change that?

## Verdict: on-the-fence

The honest scoring block is the most interesting thing I have seen on a business idea marketplace page. The contradictory social proof nearly cancels that out. I would send the three questions above before spending $5, let alone $99.
