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

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.

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. ask.mimirsystems.ai

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.

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

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. ask.mimirsystems.ai

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) arxiv.org/abs/2603.21852

Exclusive behind the scenes look at an early stage AI startup in 2026, doing proofs on a whiteboard on the floor. That's our CEO, @PeriwinkleID (PhD, ex-Meta), and our CTO, Chris (PhD, ex-Sandia)

Academic peer review is not an opportunity to make preference citation requests. If you suggest citations, you need to state specific ones, why, and how it improves the manuscript. Otherwise, we’re playing a meaningless quoting game.

Mimir is now in open beta. Ask a materials science question, if the answer is in the literature, Mimir can find it. Free for .edu & .gov emails Try it out with the link below.

Tomorrow we're opening beta access to Mimir, an AI research tool for materials science that only cites real papers from reputable journals. Ask a question, get an answer with citations from over 1 million papers.

Narrator: And none of them would answer the question of whether they use the models. I’ve never seen rightists in this much denial about AI. I wonder why it’s a left-wing thing to bury your head in the sand this much.
