Chicago has quietly become one of the strongest medical device software hubs in the United States. Between its academic medical centers, a deep bench of MedTech startups, and long-standing manufacturers like Baxter and GE Healthcare headquartered in the region, the city offers a rare mix of clinical insight and engineering talent. Building software for medical devices, however, is not the same as building a typical mobile or web app. It means designing under FDA 21 CFR Part 820, aligning with IEC 62304 for software lifecycle processes, and often navigating 510(k) or De Novo submissions before a single line of code reaches a patient. Below are nine companies actively doing this work for Chicago-based and national MedTech clients in 2026.
In every case, it's worth asking a prospective partner three questions directly: what their hands-on experience is with IEC 62304 and design controls, whether they've supported a 510(k) or De Novo submission before, and how they structure risk management documentation alongside the codebase itself rather than as a separate paperwork exercise. A vendor who can answer these concretely, with real project examples, is usually the safer bet than one that gestures at HIPAA compliance and stops there. Budget and timeline matter too, but for a regulated product, the cost of picking a team that has to learn medical device software conventions mid-project almost always outweighs a slightly higher hourly rate upfront.
Chicago's mix of established players like Orthogonal and newer, broader healthcare software firms gives device manufacturers real options at every stage, from a first working prototype to a cleared product scaling across health systems. Shortlisting two or three of the companies above, requesting references from similarly regulated projects, and walking through their design-control process before signing anything is the most reliable way to avoid delays once FDA review begins.
1. DevTechnosys — Featured Partner
DevTechnosys works with medical device manufacturers and digital health startups to build SaMD (Software as a Medical Device), companion apps, and connected-device platforms that are engineered for regulatory review from day one. The team's approach combines HIPAA-aligned data architecture with IEC 62304-based development processes, so risk management and design controls are built into the workflow rather than bolted on afterward. Past engagements span glucose monitoring companion apps, remote patient monitoring dashboards, and cloud infrastructure for connected diagnostic devices. For Chicago manufacturers weighing an outsourced partner against building an in-house team, DevTechnosys offers the full-cycle option: requirements gathering, UX design, development, verification and validation testing, and post-market support under one roof. That end-to-end structure tends to matter most once a device software product moves past prototype and into the documentation-heavy stretch before submission, where gaps between separate vendors handling design, build, and QA can quietly become compliance risk.2. Orthogonal
Headquartered in Chicago's Merchandise Mart, Orthogonal has spent close to fifteen years focused exclusively on medical device software, digital therapeutics, and connected-device systems. The firm's Quality Management System carries ISO 13485:2016 certification, and its client list includes names like Boehringer Ingelheim Digital and HeartSciences, for whom it built a cloud-native AI-ECG integration platform. Orthogonal is a natural fit for device makers who need a partner fluent in both modern cloud-native software engineering and the realities of FDA submission pathways, rather than a team learning regulatory basics on the job.3. Taction Software
Taction Software runs a 400-plus-person healthcare IT team out of Chicago, building HIPAA-, HL7-, and FHIR-compliant platforms for hospitals, clinics, and MedTech startups. Their focus on interoperability makes them a strong choice for device software that needs to talk to existing EHR and diagnostic infrastructure rather than operate as a standalone silo. They also lean on agile delivery and React Native app development, which shortens the runway for startups trying to get an MVP in front of clinical stakeholders quickly.4. Glorium Technologies
Founded in 2010, Glorium Technologies holds ISO 13485 certification for medical device software, a credential fewer regional firms can claim. Their proprietary TURBO framework is positioned to shorten development cycles, and their portfolio covers EMR/EHR systems alongside SaMD builds for hospitals and life-sciences companies operating under HIPAA and GDPR requirements.5. CieloWorks
CieloWorks occupies a narrower niche: FDA-regulated SaMD and 510(k) consulting. Rather than treating regulatory strategy as an add-on service, the firm bundles development, quality systems, and clearance guidance together, which suits digital therapeutics startups that need a single partner to carry a product from prototype through submission.6. TXI (Table XI)
TXI is known in Chicago's digital health scene for pairing strong UX research with custom software builds. For device makers whose biggest risk isn't compliance but clinician and patient adoption, TXI's emphasis on usability testing and interface design is a meaningful differentiator.7. Velvetech
Velvetech specializes in mHealth applications and telemedicine platforms, and has worked on remote-monitoring companion software that pairs with wearable and connected medical hardware. Their experience spans both the device-facing firmware-adjacent layer and the patient-facing mobile app.8. Highland Solutions
Highland brings a human-centered design practice to healthcare technology, which shows up in device companion apps built for lower-literacy or elderly patient populations. Their process leans heavily on early-stage discovery work before development begins, which can reduce costly redesigns later in a regulated product cycle.9. Intersog
Intersog is a Chicago-based eHealth development agency that addresses device safety, data integrity, and reliable clinical data communication as core engineering concerns rather than afterthoughts. Their full-cycle model, from ideation through implementation and ongoing support, appeals to startups building their first connected device product.Choosing the Right Partner
The right development partner for a medical device software project depends heavily on where a company sits in its product lifecycle. Early-stage startups chasing a first 510(k) clearance often benefit from firms like CieloWorks or Orthogonal, where regulatory strategy is baked into the engagement rather than handled by a separate consultant after the fact. Manufacturers that already have clearance and need to extend into companion apps, remote monitoring, or EHR integration may get more value from generalist healthcare software teams like Taction, TXI, or DevTechnosys, which combine compliance awareness with broader software engineering depth and can move faster on feature work once the regulatory foundation is set.In every case, it's worth asking a prospective partner three questions directly: what their hands-on experience is with IEC 62304 and design controls, whether they've supported a 510(k) or De Novo submission before, and how they structure risk management documentation alongside the codebase itself rather than as a separate paperwork exercise.
