From bare metal to the App Store.
Embedded Rust firmware, cross-platform apps, and the cloud behind them — engineered by one senior team, to hardware standards. AI-fast where it's safe, human-reviewed where it counts, owned 100% by you.
The complete product, delivered.
The application your customers use, the platform that powers it, and the web presence around it — engineered by a single team with undivided accountability.
Infrastructure built for scale
The systems behind the screen — engineered in Go and Rust to perform identically at your first user and your millionth.
Web platforms
Dashboards, customer portals and marketing sites — fast, secure, and built with React and Next.js.
Embedded systems
For connected products — wearables, sensors, devices — we engineer the firmware in-house, in Rust. Few application teams can.
LEARN MORE →Ownership, transferred
Source code, designs, infrastructure and documentation — transferred to you from day one, without exception.
Modern tools, chosen on purpose.
Picked for performance, safety and longevity — across every layer we build, and nothing we can't hand over to your own team.
AI in your product, not just ours.
We don't just build with AI — we build it into the products we ship. Assistants your customers actually use, models that run on the device, and intelligence drawn from your fleet's data.
Assistants & copilots
Chat and copilot features grounded in your own data and documents — with real evals, guardrails and cost control, not a demo that falls over in week two.
AI inside the app
Vision, voice and on-device models in your mobile app — fast, private, and working offline, because inference on the phone beats a round trip to a server.
Intelligence at the edge
Anomaly detection and predictive maintenance from your device fleet's sensor data — tiny models on the MCU where latency matters, pipelines in the cloud where scale does.
We won't bolt AI on for the pitch deck.If a search box or a SQL query solves your problem cheaper, we'll say so — AI goes in where it earns its keep, with evals to prove it.
Velocity, with discipline.
AI accelerates the routine work; senior engineers own every decision. No release leaves our hands without formal review — that is the standard, on every engagement.
Rapid first build
AI-assisted engineering delivers a working foundation in days, not weeks — surfacing the decisions that matter at the start of the engagement, not the end.
Formal engineering review
Every change is reviewed, tested and hardened by a senior engineer before release. AI accelerates our work; it never approves it.
Weekly working releases
A working build in your hands every week — progress you can measure on your own device, not in a status report.
The Appspire Sprint: proof, not promises.
Fixed scope, fixed price, fourteen days: your core concept turned into something real and clickable. Test it, show investors, and decide the full build with evidence — you keep everything we make either way.
Start a Sprint →Why teams trust us
Specialists, not generalists.
Plenty of agencies add firmware to a web shop as an afterthought. We came up the other way — embedded Rust and cross-platform mobile from the start. You're not funding a learning curve.
One team owns the result.
Firmware, mobile, web and backend, built by the same people. Nothing gets lost in a handoff — and there's nobody to point fingers at but us.
You own everything, day one.
Source code, firmware, docs and IP are yours from the start. NDA before anything sensitive, and no dependencies you can't swap out later.
New studio, senior hands.
Appspire is new; the people behind it have spent years on embedded firmware, mobile apps and large-scale backends. We work with a handful of clients at a time.
We don't take every project.If we can't deliver real value, we tell you straight away — with reasons, and a pointer to someone better suited. We'd rather be honest than busy.
Work with us, your way
Dedicated Team
You have a product. You need a team that owns it.
An embedded squad that scales with your roadmap — best for evolving products and long-term builds.
