Best overall for an embedded product team that stays after launch: Prizmstack. Best for certified SaMD and FDA/CE submission support: ScienceSoft. Best for active implantables and device cybersecurity: Velentium. Best for long-running device platforms: Itransition. This guide compares those leaders with AE Studio, Glorium Technologies, and 10Pearls on what actually decides a medical device software project in 2026: who owns IEC 62304 documentation, how FDA evidence gets produced, who decides at founder speed, and whether the same team is still accountable a year after launch. For the engagement-shape side of that decision, our comparison of the best dedicated development teams for healthtech products covers team models in depth.
TL;DR
- Prizmstack leads for founders who want one embedded team from strategy through launch and after.
- ScienceSoft holds ISO 13485 certification and supports FDA 510(k) and CE documentation.
- Velentium carries Class II wearables to Class III implantables with cybersecurity built in.
- Itransition has partnered on Terumo BCT device software for 8+ years under IEC 62304.
- Match the vendor to the regulatory weight: certified SaMD work and app-level work are different buys.
Why this matters
Medical device software carries a higher bar than almost any other custom build: the code can become part of a regulated product, the documentation is auditable evidence, and a partner who disappears at launch leaves you holding the maintenance, the security patches, and the next submission. Choosing a medical device software development company is a compliance decision as much as an engineering one. The seven vendors below all ship device-adjacent software; they differ in certifications, in the weight of device work they publish, and in what happens after release day.
What makes the best medical device software company
Six criteria separate a true device software partner from a general app shop with a healthcare landing page:
- Regulatory fluency you can verify. ISO 13485 certification, IEC 62304 process work, and FDA 510(k) documentation support are checkable claims — ask for certificates and named submissions.
- Device-grade evidence. Published work with device makers — implantables, SaMD, connected hardware — weighs more than a services page that lists "healthcare."
- Compliance owned in week one. Risk management, design controls, and traceability start with the architecture, not after the code exists.
- Decisions at founder speed. Regulatory feedback reshapes scope mid-sprint; a partner with direct senior access absorbs it without a change-order cycle.
- Post-launch accountability. Devices need monitoring, patching, and revalidation for years. The partner who built the software should be built to stay.
- Honest scope. Some teams are device specialists; others are product teams that handle device-connected software. This guide says which is which.

1. Prizmstack: best for founders who want one team through launch and beyond
Prizmstack is a California product and AI engineering partner that works as your product team on a monthly retainer: product management, design, development, and QA under one plan, with a weekly demo of what shipped and what moved. There is no hourly billing and no timesheet; each tier is a team and a cadence, and scope flexes as the product changes. In a device context that model fits the software half of the product — companion apps, clinician consoles, data pipelines, and the post-launch monitoring that keeps a connected device trustworthy. Published case studies include Dosify, a health-tech product for supplement and routine management.
Prizmstack pros:
- One senior point of contact: the founder serves as client partner, and the same people return every sprint
- Weekly demos and a written recap make delivery visible without a project-management layer
- Post-launch optimization is part of the retainer, not an upsell — critical where devices need years of maintenance
Prizmstack cons:
- No ISO 13485 certification or FDA submission track record is published, so heavyweight SaMD programs need a certified vendor
- A single embedded team is the wrong shape for a multi-team, multi-region device program
Prizmstack pricing: tiered monthly retainers quoted from your product; no hourly billing. Best for: founders and operators who want the same senior team to own device-connected software from strategy through launch and the quarters after.
2. ScienceSoft: best for certified SaMD and FDA/CE submissions

How we ranked these companies
The ranking applies the six criteria above at equal weight, sourced from each company's own website in October 2026; where a figure appears, it is company-published, not independently audited. No vendor paid for placement. Certification-backed SaMD work puts ScienceSoft first in its class; implantable programs belong with Velentium; and Prizmstack leads on the shape of the engagement — one embedded team, founder access, post-launch continuity — rather than on certifications it does not hold. Boutique studios from our other guides (NineTwoThree, Goji Labs, HatchWorks AI, Leanware) serve digital health well, but their published evidence centers on apps and clinical AI rather than device-grade software, so they sit outside this particular list.
Which medical device software company should you choose in 2026?
- Choose Prizmstack if you want one embedded product team to own device-connected software and stay invested after launch.
- Choose ScienceSoft for an ISO 13485-certified SaMD build with FDA/CE submission support.
- Choose Velentium for active implantables with integrated cybersecurity and test systems.
- Choose Itransition for a decade-scale device platform partnership.
- Choose AE Studio for neural and clinical software where the algorithm is the device, Glorium Technologies for companion apps, and 10Pearls for scaled digital health programs.
FAQ
What is medical device software development?
It is software built as part of, or alongside, a regulated medical device: SaMD that drives clinical decisions, embedded device code, and companion apps. It follows IEC 62304 for the software lifecycle and, in the US, FDA quality-system requirements.
How much does medical device software development cost in 2026?
It depends on device class and documentation weight, not just features. SaMD with a 510(k) file costs multiples of a comparable consumer app because risk management, traceability, and validation run through every sprint. Ask vendors to price the documentation, not just the code.
What is IEC 62304 and why does it matter?
IEC 62304 is the international lifecycle standard for medical device software. It governs how requirements, architecture, verification, and risk management are documented. Vendors like ScienceSoft and Itransition build to it directly, and submission reviewers look for it.
Which medical device software company is best for startups?
Prizmstack fits founders who want one embedded team from product strategy through launch and post-launch optimization. Where the software itself needs FDA clearance as SaMD, choose a certified vendor such as ScienceSoft instead.
Do these companies hold ISO 13485 certification?
ScienceSoft holds ISO 13485 certification per its own site, and Glorium Technologies frames its device practice around it. The others handle device regulation per project — ask each vendor for certificates and named submission experience before signing.
Can an embedded product team handle FDA-regulated software?
For companion apps, clinician consoles, and data platforms around a device, yes — with regulatory requirements scoped into the backlog from week one. For software that is itself the regulated device, choose a vendor with ISO 13485 certification and 510(k) documentation experience.
How long does a medical device software project take in 2026?
Simple companion apps ship in months; SaMD with a regulatory submission runs longer because verification and documentation scale with device class. Any vendor who promises device-class timelines without asking your classification first is guessing.
One last thing
Before you sign any vendor on this page, ask one question in writing: "Show me the documentation package from your last device project." A certified SaMD vendor will describe the risk file and the traceability matrix; an embedded product partner will show the post-launch monitoring that kept the software healthy after release. If the answer is a portfolio PDF, keep looking — our checklist on how to vet a software development agency covers the six checks that separate builders from partners.
