Healthcare software development is the work of building and connecting the applications that clinicians, patients and payers depend on, from patient portals and telehealth platforms to EHR integrations, claims systems and clinical analytics. Because these systems handle protected health information and sit inside regulated workflows, they must meet security, privacy and interoperability requirements that general software projects never face. That is why the choice among healthcare software development companies matters as much as the product idea itself.
This guide compares nine providers on one rule: every fact about every company below comes from that company's own website, checked in October 2026. Where a vendor holds a certification, we say so. Where it only claims alignment, we say that instead. Each entry ends with a limitation, so you know where the fit stops.
One disclosure before you read on: Cabot is one of the nine companies on this list. We deliver healthcare software development services ourselves, and we have applied the same criteria and the same limitation rule to our own entry as to everyone else's.
What Does a Healthcare Software Development Company Do?
A healthcare software development company designs, builds and integrates custom software for providers, payers and digital health businesses, under the security, privacy and interoperability rules that govern patient data in the United States.
That covers new products such as patient apps and telehealth platforms, and the less visible work that usually decides whether a project succeeds: EHR connections through HL7 and FHIR, claims and eligibility data, modernization of core systems, and the audit trail a compliance team will ask for.
It is different from buying from an EHR vendor or a device manufacturer. Those companies sell a product. A development company builds to your specification, and you own what it builds. Every company on this list is a services firm in that sense, which is also the model behind our own work.
How We Evaluated These Companies
We started from the companies most visible in US search results, then checked each against six criteria.
- Depth in healthcare. Healthcare as a core practice with its own case studies, not one industry among twenty on a services page.
- Interoperability evidence. Stated work in HL7 v2, FHIR and named EHR platforms. Integration is where most healthcare projects lose time, which is why it sits behind our own healthcare integration services and SMART on FHIR work.
- Security evidence that can be verified. A certification, an audit report or a registry entry counts. "Aligned with" and "HIPAA-ready" are recorded as claims, not credentials.
- Named clients or measured results. At least one healthcare outcome a buyer could ask about.
- Regulated software capability. Experience with software as a medical device, IEC 62304 or ISO 13485, for buyers whose product may fall under FDA oversight.
- Fit for US buyers. US presence, US healthcare clients, or demonstrated experience with US regulation.
What we deliberately left out: directory star ratings, awards and headcount. None of them tells you whether a vendor can connect to your EHR or pass your security review. Three companies from earlier versions of this list did not hold up and have been removed.

1. Cabot Technology Solutions
Best for: hospitals, health plans and digital health companies whose project depends on EHR integration and interoperability.
Cabot has built software since 2010, delivering more than 700 projects for over 140 clients, with healthcare as its core practice. The work centers on connecting systems that were never designed to talk to each other: HL7 v2, FHIR R4, SMART on FHIR, C-CDA and X12 EDI, on top of platforms including Epic, Oracle Health, athenahealth, MEDITECH and eClinicalWorks. Delivery covers telehealth, care management, patient engagement, analytics and AI, with offices in the US, Canada and India.
Evidence on record: ISO 27001 certified. HIPAA aligned, with a Business Associate Agreement signed on engagements that touch protected health information. Microsoft Solutions Partner, Salesforce partner, PointClickCare Integration Partner and AWS Partner Network member. Project detail is published in our case studies, and the integration practice is described under interoperability solutions.
Where it fits: organizations that need new software to work inside an existing clinical and administrative environment rather than beside it.
Watch for: Cabot does not hold ISO 13485, so device programs that need a certified quality management system are better served by a vendor that does.
2. ScienceSoft
Best for: medical device and SaMD products where the buyer's procurement requires ISO 13485.
ScienceSoft has worked in healthcare IT since 2005 and covers medical software, integration, modernization, analytics, AI and managed security. It is one of few firms that list SaMD development and verification testing as services.
Evidence on record: certified under ISO 13485, ISO 9001 and ISO 27001, with ISO/IEC 27701 stated on its homepage. HL7 FHIR certified implementers on staff. HIMSS Gold Member. Named clients include UNM Health Sciences Center and bioAffinity Technologies.
Where it fits: device manufacturers and digital health companies whose product may need FDA clearance, and buyers whose procurement requires ISO 13485.
Watch for: published case results are thinner than the credential list suggests, and some figures describe demonstration projects rather than client outcomes. Ask for references on a delivered healthcare engagement.
3. Kanda Software
Best for: academic medical centers and research organizations building on Epic.
Kanda covers healthcare product development, EHR integration, legacy modernization, data and AI, and medical device software. Its clearest differentiator is Epic: the company states it is an Epic Vendor Services Partner.
Evidence on record: ISO/IEC 27001:2022 certification, linked from its site to the IAF CertSearch registry, which is exactly the kind of verification a buyer should look for. Published testimonials from Dana-Farber Cancer Institute and Epion Health, and a Dana-Farber hereditary cancer risk assessment case study.
Where it fits: health systems and research institutions where Epic connectivity and clinical credibility matter more than speed of a first release.
Watch for: its medical device processes are described as aligned with IEC 62304 and ISO 13485, not certified, and its SOC 2 and ISO 9001 references come without certificate detail. Its own site does not state a headquarters or founding year.
4. Itransition
Best for: large-scale healthcare data and platform programs.
Itransition covers consulting, implementation, integration and modernization across EHR, telehealth, remote patient monitoring, laboratory systems and medical device software. Its healthcare page states experience with FDA class II and class III products and with IEC 62304.
Evidence on record: the most measurable case set on this list, including ten times faster data processing across more than 500 million patient records and a 20 percent reduction in missed appointments. ISO 9001 and ISO 27001 certification were announced on its own site in 2018.
Where it fits: enterprises with large data volumes and multi-system programs that need a partner able to staff at scale.
Watch for: its healthcare case studies are anonymized, so there are no named healthcare clients to call. Confirm the current certificates, since the announcement on record dates from 2018.
5. Velvetech
Best for: mid-market providers modernizing operations and revenue cycle.
Velvetech has served healthcare since 2004 and covers IT consulting, integration, data engineering, AI, modernization, revenue cycle management, imaging and laboratory software, and FDA-regulated SaMD work.
Evidence on record: seventeen published healthcare cases, each with a stated result. Examples include a 25 percent reduction in avoidable hospital readmissions for MedAdept and 35 percent faster claims reimbursement for CollectStream. Testimonials from Healix and MedAdept.
Where it fits: provider organizations and healthcare service businesses where operational and financial results matter more than a new consumer product.
Watch for: its security position is described as SOC 2 alignment, not a SOC 2 audit. Ask for the evidence behind it before sharing protected health information.
6. Glorium Technologies
Best for: startups and medtech companies that want ISO-backed delivery across a wide healthcare scope.
Glorium has worked since 2010 across telemedicine, EHR, remote monitoring, imaging, health information exchange, HL7 and FHIR, medical device software and AI, with an office in Houston, Texas.
Evidence on record: ISO 9001, ISO 13485 and ISO 27001 listed under certifications on two of its own pages. A published case reports doubled system operating speed.
Where it fits: buyers who want one vendor for a first product, its integrations and any device software that follows.
Watch for: the certificates are listed without the certifying body or date, so ask to see them. Its main healthcare page was last updated in 2025.
7. TATEEDA
Best for: US-based custom builds with clear accountability.
TATEEDA was founded in 2013 and is headquartered in San Diego. It builds custom healthcare software including EHR integrations, patient portals, telehealth and remote monitoring, billing, pharmacy and laboratory systems, and HL7 and FHIR integration.
Evidence on record: named US clients with stated results, including a 40 percent increase in patient engagement for La Maestra Community Health Centers, a 25 percent reduction in operational inefficiency for SCRx Pharmacy, and a near doubling of signed contracts for AYA Healthcare.
Where it fits: provider groups, pharmacies and healthcare service companies that want a US-headquartered team and named references.
Watch for: no ISO or SOC 2 certification is stated on its site. HIPAA is described as a capability, so plan your own security review accordingly.
8. Topflight Apps
Best for: venture-backed digital health companies scaling past their first release.
Topflight is based in Irvine, California, and covers healthcare product strategy, app delivery, EHR integration, telehealth, e-prescribing and modernization.
Evidence on record: a detailed published case for GaleAI reports a 97 percent reduction in coding effort and $1.14 million a year in recovered undercoding. Its site lists Cedars-Sinai, Cleveland Clinic and Stanford Medicine among its partners.
Where it fits: founders and product leaders who need product strategy and engineering together, with health system connectivity in view.
Watch for: it presents IEC 62304, ISO 27001 and SOC 2 Type 2 as standards it follows rather than certifications it holds, so verify controls directly.
9. Mindbowser
Best for: startups that need a partner with its own SOC 2 Type II audit.
Mindbowser builds custom healthcare software, EHR integrations, telemedicine, mobile health, e-prescribing and clinical decision support, and states more than 200 HIPAA- and FHIR-trained professionals.
Evidence on record: states that it is SOC 2 Type II audited. A published case describes helping a client with an Epic-integrated labor and delivery decision support platform complete its own SOC 2 Type 2 audit in three weeks.
Where it fits: early and growth stage companies preparing for enterprise health system sales, where the buyer's security questionnaire is the next hurdle.
Watch for: few healthcare clients are named on its own site, and neither a headquarters nor a founding year is given.
How to Choose the Right Company for Your Organization
The right partner depends on what kind of organization you are and where your risk sits.
- Hospitals and health systems. Integration depth decides most projects. Look for named EHR work, HL7 and FHIR experience, and a track record of application modernization for the systems that cannot simply be replaced.
- Payers and health plans. Regulatory deadlines drive the roadmap. Look for FHIR API experience and familiarity with the CMS prior authorization and interoperability requirements described below.
- Digital health companies. Speed to a credible first release matters, but so does surviving the first health system security review. A partner experienced in AI-accelerated MVP development and in enterprise sales readiness will save a rebuild.
- Medtech and SaMD. Once a product could fall under FDA oversight, a certified quality system and IEC 62304 discipline move from preference to requirement.
- Virtual care providers. Licensing, scheduling, billing and prescribing logic carry more risk than video. Look for a telemedicine software development company that builds those rules as configuration.
Five questions worth asking in the first call:
- Which EHRs have you integrated with in the last two years, and can we speak to that client?
- Will you sign a Business Associate Agreement, and what does it cover?
- Can we see your current certificates or audit report, not a badge?
- Who owns the code, data and infrastructure accounts if we end the engagement?
- Who on your team is accountable for compliance decisions, by name?
How to Verify a Vendor's Compliance Claims Before You Sign
Most vendor risk sits in the gap between what a website says and what a contract guarantees. Five checks close most of it.
Separate certified from aligned. A certification means an accredited third party audited the company. "Aligned with", "HIPAA-ready" and "built to standards" mean the vendor assessed itself. Both can be honest, but only one is evidence.
Look up ISO certificates in a registry. Ask for the certificate number and certifying body, then check it in the IAF CertSearch database. A certificate that cannot be found should be treated as unverified.
Ask for the SOC 2 Type II report itself. A Type II report covers how controls worked over a period, usually six to twelve months. A Type I report covers a single point in time. A badge or a statement of alignment covers neither.
Read the Business Associate Agreement before the statement of work. It should define permitted uses of protected health information, breach notification timelines, subcontractor obligations and what happens to data at exit. Our guide to building HIPAA-compliant software covers the engineering side of the same obligations.
Settle ownership and exit terms early. Source code, cloud accounts, encryption keys, documentation and data should transfer to you on request, without a separate negotiation.
US Regulations Your Development Partner Should Already Know
A capable partner should raise these before you do, because each shapes architecture decisions that are expensive to reverse.
CMS Interoperability and Prior Authorization Final Rule. Finalized by CMS on January 17, 2024, it applies to Medicare Advantage organizations, Medicaid and CHIP programs and managed care plans, and qualified health plan issuers on the federal exchanges. Since January 1, 2026, most of these payers must decide prior authorization requests within 72 hours for urgent requests and seven calendar days for standard ones. By January 1, 2027, they must implement the Patient Access, Provider Access, Payer-to-Payer and Prior Authorization APIs. In April 2026, CMS proposed extending these requirements to drugs.
Information blocking. The HTI-1 final rule, published in January 2024, updated certification requirements for decision support interventions, added algorithm transparency, and made USCDI version 3 the only baseline from January 1, 2026. Since July 2024, providers found to have committed information blocking face disincentives through Medicare programs. ONC has also proposed HTI-5, which would narrow several certification requirements, including those for AI. Software that holds or exchanges patient data has to be designed so it does not create information blocking risk for the organization that runs it.
Nationwide exchange under TEFCA. The Trusted Exchange Framework and Common Agreement is the federal framework for nationwide health information exchange. If your product will exchange records across organizations, ask how your partner would connect through it.
FDA oversight of clinical software. Software that informs or drives clinical decisions may be regulated as a medical device. Whether it is depends on what the software does and how a clinician can review its output, which is why that question belongs in discovery, not after launch. Teams adding AI to clinical workflows should settle it alongside their healthcare AI consulting decisions.
How Cabot Approaches Healthcare Software Development
Cabot starts with the systems a new product has to live alongside. Integration and data flows are scoped first, because they set the timeline more than any feature list does. Security and HIPAA obligations are designed in from architecture, under an ISO 27001 certified management system and a signed Business Associate Agreement.
Where AI is part of delivery, Cabot stays model-neutral, a named engineer reviews every AI-assisted change before it merges, and client code and patient data are never used to train a model. Testing is planned as its own workstream through our QA and testing practice, not squeezed into the end of a sprint.

Conclusion
There is no single best healthcare software development company, only the best fit for your organization, your regulatory exposure and the systems you must connect to. Shortlist on integration evidence, verified security credentials and named results, ask the five questions above in the first call, and check every certificate before you sign. The vendors worth hiring will welcome the scrutiny.
