Bringing your ideas to life.
StelTech LLC is an independent engineering practice working with inventors, small businesses, and municipalities. We specialize in new product prototyping, manufacturing, as well as process control and automation on an industrial scale.
If you are looking to develop a new product or optimize the way a current product or process works, you have come to the right place.
From sketch to pilot run
Fig. 1 — Development sequenceArchitecture
Block diagram, part selection, schematic capture, and the control approach the whole thing hangs off.
OUT: Schematic + bill of materialsPrototype
Board layout, firmware, and bench testing until there is a physical unit that does the thing on purpose.
OUT: Working prototype + test dataDesign for manufacture
Enclosure, tolerances, cost reduction, test fixtures, and assembly documentation a contract shop can follow.
OUT: Production drawing packagePilot & handoff
Supplier quoting, first-article checks, and the complete file package so you are never locked to one engineer.

Confidentiality
NDA signed before you share anything specific. Your idea does not get discussed, reused, or shopped around.
Ownership
Work done for you belongs to you. Schematics, source code, and CAD are handed over at the end of each phase.
Honest answers
If an idea will not work, or is cheaper to buy than to build, you hear that early — while it is still just a conversation.
Industrial engineering
For plants, municipalities & integratorsProduct development pays the rent, but plant work is what got us here. These services stand on their own — and they're the reason a prototype from this shop tends to survive contact with the real world.

Tell me about your idea
Replies come from jonathan@steltech.llcA rough sketch and a paragraph is plenty to start. You don't need drawings, a patent, or a finished plan — that's what the first phase is for.
If you'd rather sign an NDA before saying anything specific, say so in the message and we'll do that first.

Thanks — I have your details and will reply from jonathan@steltech.llc. If you'd like an NDA in place before we get into specifics, just say so in your reply.
