Introducing Vesta

The AI for your closet

Vesta gives you daily outfits based on your wardrobe, your schedule, the weather, and your style.

The days of having “nothing to wear” are over.

Idk man it's a pretty great way to justify telling the kids at the family gathering why you definitely know they should help with the dishes
(Because I'm a CEO, obviously)

[Samuel Spitz @samuel_spitz]

Being “CEO” of a pre-seed startup is like being the prime minister of a country that doesn’t exist

[Periwinkle, PhD @PeriwinkleID]

Do I deserve a bottle of champagne for being a female founder or do I have to wait for the seed round

[joowon @n0w00j]

there are 3 notable moments in a startup’s life:

- first round of funding
- $1m ARR
- the first woman joins the company

today we are celebrating @mayarox5. welcome to Melius. popped some champagne.

The bulk of contemporary academic literature is in English, but your answers don't have to be

Instead of uploading papers to ChatGPT to ask for a translation and hoping it's ok, ask the question directly to a system that's read the paper

[Mimir Systems @MimirSystems]

Did you know you can ask Mimir a question in Arabic, Chinese, French, or any major language and get a cited answer in the same language?

The papers are in English. The answer comes back in yours.

Coming back from a Starbucks run in UWS wishing I had a business card on me because I'm overhearing a woman on the phone walking her dog complaining about ChatGPT citing things that aren't real

[Periwinkle, PhD @PeriwinkleID]

Awesome week at @SAMPE and huge thank you to UW ACC for having us

[Mimir Systems @MimirSystems]

That's Chris, our CTO, who spent last week with our CEO @PeriwinkleID at @SAMPE 2026 in Seattle, judging the student poster competition.

There were numerous posters on composites, polymers, and advanced materials manufacturing.

They were then invited to tour UW's Advanced Composites Center. Good week to be a materials scientist.

I raise you agent still running but I need to get to my gate

[resham ☻ @Reshusaur]

new walk of shame:
agent still working, but the cafe closed

@carsonarkova It's a contingency plan and also a looking death sentence tbf

[Mimir Systems @MimirSystems]

Come chat with us, tell us what's broken in your literature search workflow, what you're working on, and what we should build next.

Researchers, grad students, professors, and @SAMPE attendees from industry are all welcome. RSVP appreciated.

It's actually oddly difficult to answer questions like "what are the canonical papers in this field" unless you have a professor on hand to rattle them off

But now, you can ask Mimir

If the answer is in the literature, Mimir can find it ™

[Mimir Systems @MimirSystems]

Starting in a new field and figuring out which papers are actually foundational vs. just highly cited is one of the worst parts of research.

So we built a tool that surfaces them instantly instead of making you dig through citations for hours.

My Co-founder got so mad about this he shared it in our slack channel with this comment:

[Lukasz Olejnik @lukOlejnik]

Physicist has written a fascinating big beautiful paper.Let’s not be afraid to call it what it is - groundbreaking. For hundreds of years, mathematics had dozens of “basic” functions: sine, cosine, logarithm, square root, exponential. You know these from school. Everyone does. Now it turns out that all of it is one single operator:
E(x, y) = exp(x) - ln(y), and the constant 1.
Sin, cos, π - everything follows from this neatly , just nest it properly. Nature hid the simplest possible description of reality. And it was just been found. The whole thing is beautiful and remarkable, here the word “groundbreaking” is not a marketing buzzword.
For instance, instead of writing π or 3.14, one can now elegantly write E(E(E(1,E(E(1,E(1,E(E(1,E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(E(E(E(1,E(E(1,E(1,E(E(1,E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(1,E(E(1,E(E(1,E(E(1,1),1)),E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(1,1)),1))),1)),1)),1)),1))),1)),E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(1,E(E(1,E(1,E(E(1,E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(1,1))),1))),1)),1)),1)),1),1),1))),1))),1)),E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(1,E(E(1,E(1,E(E(1,E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(1,1))),1))),1)),1)),1)),1)

@StephNass Eh, if you go to min check size of 10k on 500k you can end up with 50 people you have to answer to

The minimum check size depends on how valuable the angel is outside their investment, and how much work they'll be to manage
