A design-led software studio building small, focused SaaS products for underserved creative and professional markets.
Kyyber is structured to ship a small family of SaaS products. Each one is tightly scoped, aimed at a real and proven market, and deliberately built for people who have been ignored by the incumbents — because the incumbents were built for everyone at once.
The categories we enter are crowded and mature, but the existing products feel dated and clumsy. Our edge is craft: interfaces that are clearer, faster, and more beautiful than anything else in the space. Design is how we earn the first look, and how we keep it.
We talk to our customers every day. Product decisions come from observed usage and direct conversations, not from committee. Retention is the first metric we chase; growth comes after the product is something people cannot put down.
We run a specification-driven development pipeline: humans author precise specs and behavioral scenarios, AI agents do the implementation, and an automated validation harness proves the result. The result is the speed of a large engineering team with the taste and coherence of a two-person studio.
Every feature begins as a precise written specification — who it's for, what they see, what must never happen. The spec is the contract. If the spec is vague, the output is vague.
AI agents implement against the spec inside a strict type-checked harness. Compilers, linters, and behavioral scenarios enforce correctness the agent cannot bypass. Code is treated as opaque — we evaluate what it does, not how it was written.
Human designers and engineers review the running product, not the diff. We curate a library of behavioral scenarios that live outside the codebase — the agent cannot see or optimize for them. If the scenarios pass, the behavior is correct.
Releases happen continuously. When a customer reports a problem, the spec gets an update, the factory runs, and the fix ships the same day. Speed is the product.
Engineering leader with 12+ years in consumer technology and 7+ years managing engineers. Built production-grade LLM features and the AI engineering foundation behind them — evals, agent tracing, versioned prompts, and a tested capacity envelope.
At Kyyber, AJ is the technical co-founder. He owns the architecture, the agent pipeline, and the controls that keep the factory shipping safe, correct software at high velocity.
Senior product designer and creative leader with 7+ years designing and scaling SaaS products, growth surfaces, and design systems. Scaled a multidisciplinary agency from zero to $3M+ in revenue and led end-to-end design on subscription platforms used by creators worldwide.
At Kyyber, Mack owns the product voice, the design system, and the specifications that drive every build. Design is how we earn the room — Mack is why our work is worth looking at.
