One-stop engineering solution

Final requirements.A hands-on MVP in 7 days. Guaranteed.

From design validation and finalization to integrated piloting and a working prototype. Electronics, firmware, backend, PWA, mobile applications, and enclosure design—coordinated through one engineering workflow.

For agreed rapid-pilot projects, starting from signed-off requirements and confirmed component availability. See the seven-day commitment.

Beyond the pilot, we can support mass production, factory setup, tooling, test benches, and logistics. Explore production services.

Engineering depth. Delivery speed.

Fast because the work
is connected.

Our engineering journey began in 2000. That experience helps us choose practical architectures, recognize integration risks, and focus each pilot on the behaviour that matters.

Experienced judgment

Know what to resolve first.

Software, embedded electronics, appliances, IoT, and metering experience inform the choices behind every pilot. Experienced engineers guide the work and make the trade-offs visible.

Automated infrastructure

Shorten the feedback loop.

AI-assisted engineering, coordinated specialist workflows, automated builds, repeatable deployments, and device testing reduce handoff delays and keep the current design, software, and evidence connected.

Physical prototyping

Test something tangible.

CNC PCB milling, component assembly, 3D-printed enclosures, and engineering instruments help turn a design into a testable assembly while firmware and applications develop alongside it.

One coordinated workflow

From a defined requirement.
To a working product.

01 / Validate & finalize

Make the requirements buildable.

A fast pilot starts with engineering clarity. We turn the intended use case into a coherent design, an achievable MVP scope, and a shared definition of success.

Design validation
Review the system architecture, interfaces, component choices, electrical constraints, enclosure needs, and operational workflow. Identify dependencies and resolve the decisions that would otherwise interrupt the build.
One product, across disciplines
Finalize schematics and prototype PCB layout alongside firmware architecture, backend interfaces, PWA and mobile application flows. Mechanical design considers connectors, assembly, access, and the realities of the first physical prototype.
A clear starting line
Agree the final requirements, acceptance criteria, prototype deliverables, and available components before the seven-day pilot begins. An existing design can enter here for review and finalization; a new concept can be developed into the same defined starting point.

02 / Build the pilot

Hardware and software. Moving together.

Our rapid-piloting workflow keeps electronics, enclosure development, firmware, and applications coordinated—so the first assembly is already part of a working system.

Rapid PCB and PCBA prototyping
Use CNC milling to produce prototype circuit boards where the board technology is suitable, followed by component assembly, inspection, and bring-up. Complex multilayer boards or specialist fabrication are assessed during scope finalization.
Rapid enclosures
Use 3D printing to turn mechanical designs into tangible housings, lids, mounts, and fixtures. Check fit, connector access, assembly, and usability early, then iterate while the electronics and software are being integrated.
Firmware, backend, PWA & mobile
Build the agreed end-to-end workflow across device firmware, backend services, browser-based progressive web applications, and mobile interfaces. Shared contracts, automated builds, and repeatable deployment keep the parts aligned.

03 / Validate & hand over

A product you can put to work.

The outcome is a hands-on minimum viable product: a tangible prototype that demonstrates the agreed core workflow and gives your team evidence for the next decision.

Integrated functional validation
Exercise the complete path from physical inputs and firmware to backend behaviour and the user interface. Combine bench measurements, automated checks, and hardware-in-the-loop workflows where appropriate.
Pre-certification preparation
Review applicable requirements and perform agreed preliminary checks to identify issues before formal laboratory testing. Pre-certification work prepares the design; it is not a certification award or a guarantee of laboratory approval.
An actionable handover
Demonstrate the agreed acceptance criteria, hand over the pilot and agreed engineering artifacts, and document findings and remaining work. The next phase can address design refinement, formal certification, manufacturing readiness, and production qualification.

The seven-day commitment

A clear promise.
A defined deliverable.

We guarantee a hands-on MVP in seven days for projects accepted into our rapid-pilot service.

Before the clock starts, we jointly sign off the final requirements, core workflow, prototype scope, acceptance criteria, component availability, and project-specific guarantee terms. The commitment applies to those agreed deliverables.

The MVP is a functional engineering pilot—not a fully qualified production product. Specialist procurement, scope changes, formal certification, manufacturing tooling, and production qualification require separately agreed schedules.

Pre-certification preparation can form part of the pilot. Formal approval remains with the relevant testing and certification bodies.

Beyond the pilot / Production services

Prove the product.
Build the capability to deliver it.

A working pilot is the beginning. We can carry the engineering forward into mass production and help establish the factory, tooling, test systems, and supply flow needed to deliver repeatable products at scale.

01 / Mass production

From pilot to production.

Refine the design for manufacture and assembly, prepare production documentation and the bill of materials, and coordinate sourcing, assembly, and production ramp-up. Align manufacturing capacity, volumes, and acceptance criteria with the agreed product and delivery plan.

02 / Factory setup

Build the operating environment.

Plan production layouts, process flow, equipment selection, workstations, and supporting infrastructure. Support installation, commissioning, work instructions, and operator training so the facility is ready for its intended product and process.

03 / Tooling & fixtures

Make repeatability practical.

Develop assembly jigs, programming fixtures, inspection aids, and product-specific tooling. Coordinate enclosure tooling and manufacturing partners where required, with fit checks, trial builds, and agreed tooling acceptance before production release.

04 / Test benches

Verify every production step.

Engineer test benches for board bring-up, firmware programming, calibration, and end-of-line functional checks. Connect fixtures, instruments, and automated software to defined test limits, serial-number traceability, and reviewable results.

05 / Supply chain & logistics

Keep materials and products moving.

Coordinate component procurement, supplier lead times, inventory planning, packaging, and delivery logistics. Plan material availability and shipment milestones alongside production, including domestic and international coordination as agreed.

06 / Quality & readiness

Carry evidence into the factory.

Define inspection points, acceptance procedures, revision control, and the handling of nonconforming units. Support reliability checks, certification preparation, and TKDN documentation coordination where applicable; formal approvals remain with the relevant authorities.

A collaborative manufacturing network

Engineering led by Callysta.
Production accelerated by partnership.

Our engineering capability is backed by an extensive network of manufacturing and supply-chain partners—bringing specialist processes and production capacity into one coordinated product journey.

Through these partnerships, we can coordinate PCBA assembly, injection-mold tooling, plastic and metal injection processes, electronic-component sourcing and logistics, and access to production lines. The right partner and process are selected around the product, material, volume, and quality requirements.

Shared planning lets component procurement, tooling preparation, assembly readiness, and test development progress together. By connecting our engineering work with partners’ specialist facilities, we help shorten handoffs and accelerate the transition from validated design to repeatable production.

Callysta connects design decisions, manufacturing documentation, test requirements, and acceptance criteria across the network. Partner facilities complement our in-house engineering resources; capacity, responsibilities, and delivery milestones are confirmed for each project.

Production services are scoped separately from the seven-day MVP commitment. Capacity, tooling ownership, procurement responsibilities, factory requirements, qualification work, and delivery schedules are agreed for each engagement.
