Not a job. I’m exploring alignment with a potential partner.

I’m a systems builder (CS/infra founder; shut down my last startup) who spent the past two years going deep on foundational math that most engineers (and I guess many mathematicians) tend to ignore, largely at an nLab level, because standard abstractions stop composing.

I’m working toward a small, private apply-focus lab to bridge native CS intuition (computation, scale, systems) with structural, information-theoretic mathematics. The focus is composability, learning, universality, and complexity, with the intent to build, not publish.

The approach is unconventional, but intentional: staying close to real systems while reworking foundations when existing methods stop composing.

Looking for a self-funded generalist comfortable crossing CS, math, and theory that's interested in structure, information, ethics, and long-horizon work.

Mozart AI is a Digital Audio Workstation (DAW) with built-in AI Co-Production. We empower what we call the ‘Hybrid Musician’, an artist driven by human creativity and assisted by AI. You could say we want people to become “vibe musicians”.

We started around 8 months ago, have 80k+ beta users, and have been Product Hunt’s Product of the Day twice. Seed-stage (oversubscribed, will be announced soon) with meaningful equity for every role.

We’re hiring 2 engineers:

Full-Stack Engineer (Frontend-leaning): product UI/UX, React, Zustand, realtime-ish creative workflows, making the browser feel like a native studio

Full-Stack Engineer (Backend-leaning): platform + APIs + data and db design, reliability + performance, supporting fast product iteration

What you’ll like here:

Small team, high ownership, ship fast (by choice, you feel the urgency to change music creation)

Working on generative audio + creative tooling (hard but really fun problems)

Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses.

We are seeking a developery-data person with experience specifically with CloudSuite Distribution by Infor for one of our clients. It may be a bit of a shot in the dark, but if you have worked with this *specific* ERP system before, we'd be eager to talk to you. Reach out at "ekib.eikooc@rofni".reverse() Please include your experience in your email body/subject as we will have to quickly triage out most of the spam.

PS. Each time I post here I get ~500 emails, almost all are low effort that don't meet anything I am looking for, sometimes for months in the future. I expect it to be even worse as LLMs gain traction. I've hired 4 people from past posts (check my history if you want!), but it can take some time dig through everyone so I apologize to legitimate interests.

I’m building ActorDo, an AI work assistant that actually helps people get work done. Email, calendar, tasks, context. Product is live. Users are using it.

Now I’m looking for a growth partner, not a tactic executor. With experience on US market.

This is about: - positioning and narrative - real distribution wedges - fast experiments and feedback loops

Close to product. Close to users. No fluff.

Looking for a self-driven growth marketer who likes early-stage chaos, thinks in systems, and wants real ownership.

If this clicks, let’s talk. Must provide references.
