f(x) = y
Functions that resolve pain. Including yours.

We don't just integrate APIs.
APIs are necessary. They aren't enough.
Foundation
Superfunction
An open-source architecture that integrates the foundations every full-stack app needs.
──From auth to AI integration — a consistent base, not rebuilt every time.
Deployment
SuperCloud
A platform that makes deploying and operating Superfunction apps easy.
──Ship with one command. Observe in production.
Context
Eaven
Architectures and engines that give AI what it needs to know.
──Memory, retrieval, learning.
Foundation
Superfunction
x
Every piece of software begins with login.
Auth. Email delivery. API integration. AI integration.
The foundations every piece of software has to build,
each implemented at a different level of quality.
f
Superfunction is an open-source architecture
for integrating those foundations seamlessly.
Auth. Email delivery. API integration. AI integration.
The foundations no software should re-implement every time —
held at a consistent quality.
The same foundation we run on,
available to anyone in the same shape.
y
Developers focus on the business logic.
The foundation stays alive, at consistent quality.
This page runs on it.

Deployment
SuperCloud
x
Software doesn't end when it ships.
That's when operating begins.
Deployment. Monitoring. Scaling. Logs. Alerts.
Everything that keeps software alive
ends up scattered, repetitive,
and never quite visible.
f
SuperCloud makes everything needed to operate
a Superfunction app easy to handle.
Deployment, monitoring, scaling, logs, alerts.
None of them need to be built separately.
Every Superfunction app we build runs on it.
y
Developers focus on the business logic.
Operations stay coherent, automated, fully visible.

Context
Eaven
x
AI models only know what they were trained on.
Business data. Real-time information. Internal knowledge.
For AI to do real work, it needs to reach all of this.
The standard RAG approach works well —
finding related information through semantic similarity.
But semantic similarity doesn't guarantee
accurate information retrieval.
f
Eaven is a search engine designed for AI,
built around accurate information retrieval.
It treats semantic similarity alongside structure,
relationships, and time — all as dimensions of search.
It gets sharper the more it's used.
Every AI we build answers through Eaven.
y
Developers focus on prompt design.
Eaven supplies the information each answer needs.

Product
Superself
A personal agentic OS that composes the functions you need into a single subscription.
x
Daily tools are fragmented.
Calendar, notes, chat, search — separate apps, separate subscriptions.
People end up translating between them.
f
Superself composes the functions you need into one OS.
Calendar, notes, chat, search, memory — held in a single context.
Pick what you need. One subscription.
y
Users focus on their work.
The tools move with the context.
