2 assertions · 1 opinion · 5 insights · every statement was checked. The predictions and assertions are the 2 claims: statements the public record can support or contradict. 0 are resolved, and 2 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

What the tape says about how Stephen argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Stephen Slattery on measured tape to publish a rate. This says nothing about how they speak.

Opinion
Slattery: Nominal's early team surpassed engineering groups at SpaceX and Anduril
“Meeting the initial folks at Nominal, it was evident from those conversations that this team was above and beyond even those groups I had worked with at Andrel and at SpaceX, so that was extremely exciting.”

Assertion Not checkable as stated
Slattery: SpaceX always checks to buy before deciding to build
“SpaceX is always going to look and see first if they can go and buy something before they go and build it themselves.”

Insight
Slattery: Custom hardware toolchains rarely generalize to subsequent product lines
“They might have built a tool chain that worked very well for product one, but almost always what we're seeing is that it's typically over tailored to that system in terms of the data types it supports, the analysis workflows, how commoditized it is. And then t…”

Insight
Slattery: SpaceX and Anduril diaspora is standardizing hardware data models
“One of the things that's made nominal possible now, or say three years ago, is that there is this crunch happening across all of these disparate industries in terms of the data types that they are using. Where, 20 years ago, if we were going in and trying to i…”

Slattery: Maritime, nuclear, and aerospace share identical core telemetry needs
“What we're seeing, you know, maritime, nuclear, aerospace, is that we're not getting bombarded with a million different maritime-specific feature requests. Right. We're seeing a lot of commonality across these industries. Folks want the same answers. They want…”

Assertion Not checkable as stated
Slattery: SpaceX has invested millions into custom internal software toolchains
“Going to SpaceX, they've invested millions in their tool chain, everything from ERP to fleet management. To data analysis, obviously.”

Insight
Slattery: Onshoring hardware supply chains demands massive continuous component re-testing
“Once you find that vendor, the next thing that happens is testing. If I'm, you know, previously was buying my brushless motor from China, and now I'm gonna buy it from a US vendor or a Czech vendor, whoever it might be, that is a test campaign that needs to go…”

Insight
Slattery: Hardware acceleration depends on rapidly proving safety of minor improvements
“Where you got this acceleration, if you're a SpaceX or an Andrel, is how fast can I identify an improvement I want to make and then convince my customers That that is a safe improvement, and that I can deploy that into the field, whether it's new software or a…”
