This is the future of how software gets built.
Quelm builds AI-powered software — for our clients and for ourselves.
We don't consult. We ship.
We build software that
didn't exist yesterday.
Custom AI software
We design and build bespoke AI tools for companies who need something that doesn't exist yet. No templates. No off-the-shelf. Just the exact tool your team needs, built properly.
Our own products
We ship software under the Quelm name. If we see a problem worth solving, we build the solution. We eat our own cooking — everything we make for clients, we've used ourselves.
AI strategy
We help teams understand what's possible, what's worth building, and what to avoid. Straight answers, no jargon, rooted in what we've actually shipped.
Shipped under our name.
Used in the real world.
TokenCap
AI cost control. Actually enforced.
TokenCap prevents AI cost explosions by enforcing hard spending limits on API calls — blocking them before they happen, not alerting after the money is gone. Works with 220+ models across all major providers. Sub-50ms enforcement.
Quietburn
Burnout detected. Privately.
An offline AI journaling companion that watches your entries over time and warns you about burnout before you notice it yourself. Runs entirely on your device — no data ever leaves your machine.
Our principles.
Non-negotiable.
Responsible AI
We use AI where it genuinely helps — not because it's fashionable. Every system we build is explainable, auditable, and does what it claims to do. No black boxes, no hype.
Explainable AI
Every output references its evidence. No black boxes, no "the AI said so". Every insight is traceable back to the data that generated it.
Ships fast
We make decisions quickly and build the minimum that works brilliantly. We'd rather put something real in your hands than perfect something nobody's used.
Built to last
SaaS products are engineered for reliability and scale. Custom work is yours to own — no lock-in, no dependencies on us. Either way, you get something that works long after we're done.
Work with us —
