Factos by @noxmetals has a single "Opportunity" primitive that follows a metal order from RFQ to shipment. But our different departments need different things out of this primitive- sales needs to know fulfillment status, procurement needs to know what to buy, and the shop floor needs to know what plates to cut
Building a data model that serves each department without accumulating too much duplicated state and syncing logic is a challenge
To do this, Factos maintains several state machines at the grain where each fact is true- deal, line, shipment, plate, saw task, and material purchase- then rolls them up into the views each team needs
As our workflows evolve and company scales, it's a balance we constantly revisit

Nox Metals exists so America can build 100x more factories and technologically abundant industrial capacity in the West.
We are announcing our $11.5M Seed round led by Hyperion, with participation from Palmer Luckey, Y Combinator, Jared Friedman, RoboStrategy, Operator Collective, DTX, Alumni Ventures, and others.
Over the past few decades, America has neglected domestic production. We lost our dominating ability to build in the world of atoms while jobs on the factory floor plummeted.
It's time to build for America again. As our grandparents once did.
Since launching production only 7 months ago, we have shipped metal to hundreds of American factories. Countless truckloads to America's industrial base. And we are no where near slowing down.
Our metal has gone to space. It has protected our troops. It is in your car and in the machine that scanned your chest. It is all around us. And we can't stop supplying at warp speeds, because America needs it.
We will be revitalizing a WW2 era, 35,000 SQFT factory in Detroit this summer where we will have our techno industrialists working hard to further pursue our mission. We will be tripling down on technology, which has allowed us to move this fast for America thus far.
More code. More machines. More metal. More production.

I want to talk about our most brutal week at @noxmetals this week.
Even though it was the one with the most revenue we have ever done.
We have a unique perspective because a lot of American manufacturers reach out to us all day long to ask for metal to make parts.
We have this view where we see how busy these shops and factories are.
And the requests just don't stop coming in. We turned down an additional 50% of monthly goal revenue because we are just too busy and it sucks. Which is obviously a really good thing but what's super clear is the lack of capacity and technology American manufacturing has to keep up with itself and grow.
We just got so busy so fast. I honestly feel like we found a really strong product market fit. As soon as we launched our instant quoter, our customers were able to get lead times and prices that worked for them 1000x faster than on average.
Also, I feel strongly that we haven't even had that much net new customers but just an insane amount of repeat customers. It's like okay we have been really only cutting for 3 months and we figured out what works: fast fast metal cheaper than the competition and still good margins for us.
I think all the shops move so slowly because their supply chains are slow. Like right now we are slow and it sucks. Because we simply need more technology and capacity - which we are building/implementing but there's a slight lag in the world of atoms.
I guess this all is being said that manufacturing is extremely hard to do fast and cheap - but simultaneously it is so damn worth it because the customer response is great.
I am super thankful for our team for working 85 - 100 hour weeks last two weeks. And getting to work on such an important problem is very very fun.

Modern Metal Mills
@zanehengsperger
Reindustrializing the U.S. isn’t just about labor or geopolitics—metal mills are slow because they run on outdated systems.
Modern software creates an opportunity for mills to cut lead times and costs while improving flexibility and margins.

What US city has the largest gap between national perception and reality?
My answer: Detroit
Everyone seems to think it’s a run down hell hole w nothing but boarded up buildings.
In reality:
> Completely rejuvenated downtown w businesses, residential, restaurants, & nice sports venues – Ford Field (Lions), Comerica Park (Tigers), Little Caesars Arena (Pistons & Red Wings)
> One of the best airports in the country – Delta hub w direct flights all over the world
> Tons of history, culture, and classic architecture
> Diversifying economy beyond auto into tech, medical, etc.
> People are genuinely nice but also super tough & resilient
Of course it’s not all unicorns and rainbows. While some parts of the city are making a comeback, others are being left behind.
There’s crime, traffic and all the other things most big cities battle.
But if Detroit has a national reputation of 1/10, in actuality I think it’s more like 7/10.
