# Jordan Yee, Staff Engineer at Amplitude (Series D, ~600 people) — read of DeltaDB, June 12 2026

> 11 years in eng, the last 3 as staff. Two kids (4 and 8). I bike commute 22 minutes each way and spend most of it thinking about whether I'm ever actually going to ship something of my own.

## How I got here

Bram Kaminski posted a link in the Bootstrappers Slack with zero context, just "interesting idea marketplace." I clicked because I'd been thinking about developer tooling for a side project and wanted to see what other people were cooking. I expected another landing page generator or no-code pitch deck. I did not expect this.

## What I clicked first

The hero copy stopped me: "See exactly what you changed at 2pm. Why it broke. What you were thinking."

That's weirdly specific and good. Not "gain unprecedented visibility into your development workflow." Someone actually thought about a real moment. The 2pm detail is the kind of thing you only write if you've sat there at 4pm trying to reconstruct what you did two hours ago and failing. I've done that. That line works.

But then I scroll and realize I'm not buying DeltaDB. I'm buying a dossier about how to build and sell DeltaDB. The page doesn't say that up top. There's a full product presentation -- "Start Capturing," "View Demo" -- and then somewhere in the middle it pivots to "60/100 Adoptability" and "Honest disclosure: we don't have live customers on this idea yet." Those two frames live on the same page and they fight each other.

## Where I paused

"buyer clarity: 10/10" listed as a strongest axis, but landing page quality is "2/10." And the page is scoring its own landing page. That's either extremely self-aware or a sign that no one cleaned this up before shipping. I genuinely don't know which. I sat on that for a minute.

## What I distrusted

"Your brain as a search engine." I know what they were going for. I don't think it lands. It's trying to sound poetic and instead it sounds like marketing copy that got workshopped one too many times.

Also: "$-29,500 Year-1 take-home (Fermi)" and "1 in 8 Meaningful-success odds" are shown as if they're selling points, but they're actually pretty brutal numbers. Year 1 in the red by nearly 30k and a 12.5% shot at meaningful success. That's honest, I'll give them that. But if those numbers are the product, I want to understand how the Fermi model works before I hand over $5 or $99 based on it.

The "View Demo" link in the hero probably goes nowhere or links to something very thin. I'm guessing it's a video walkthrough of a prototype. That's fine but don't put it next to "Start Capturing" if there's nothing to capture yet.

## What would convince me

I want to see one real engineer who used a prototype of the session log and described a specific moment where it saved them. Not "Jordan saved 2 hours" -- I mean "I pushed a bug to staging at 2:47 PM, closed VS Code, came back at 5:30, and pulled up the session replay to find exactly where I broke the auth redirect." That. One real incident, described like a person.

On the dossier side, I want the Fermi model to be visible. Not summarized -- I want to see the actual assumptions. If you're asking me to trust "$-29,500" as a number I should bet $99 on, show me the spreadsheet.

## What I'd ask in an email reply

1. The hero says "Zero overhead" for the session recorder -- how? Recording every keystroke and edit continuously is not obviously free. What's the actual capture mechanism and where does the data live?
2. Is there a working version of the query interface, even a toy version? "Find all edits to a function" is the feature I'd actually pay for, and I want to see what the query language looks like before I believe it's real.
3. You score your own landing page at 2/10. Is that score based on something structural (conversion rate benchmarks, copy review) or is it just a candid self-assessment? I'm asking because if the scoring is rigorous, the score means something. If it's vibes, it means less.

## Verdict: on-the-fence

The honest numbers and the 2pm specificity are real differentiators from the idea-marketplace stuff I've seen before. But the page tries to be two things at once -- a product page and an idea dossier -- and neither one is fully finished. I'd click the $5 unlock if the query interface demo was real.
