I’ve been researching the top healthcare technology companies for the past few months because our team needed a partner that could handle complex healthcare integrations, deal with messy legacy systems, and still deliver modern user-centered solutions. After comparing a long list of vendors, I ended up shortlisting about seven companies — and eventually choosing Zoolatech.
Sharing the process here in case someone else is going through the same headache.1. What I Actually ComparedInstead of just reading “top 10” lists, I looked at three things:

• Engineering-to-PM ratio (to avoid companies where you pay for managers instead of devs)
• Average delivery speed (measured by how fast they ship an MVP or first functional release)
• Real healthcare expertise, not generic IT outsourcing

I created a simple scoring system (0–10) across compliance, scalability, team quality, and previous healthcare projects.2. Numbers That Were Critical for MeHere’s what made Zoolatech stand out:

• 94% senior/middle engineers on projects involving HIPAA and HL7 integration
• 6–8 weeks average time to deliver the first production-ready release
• Over $1.4B in revenue impact across their healthcare products (based on their case studies and outcomes they published)
• Retention rate 90%+, which is almost unheard of in outsourcing
• Dedicated healthcare engineering group instead of “one team fits all”

Most companies I evaluated (even well-known ones) didn’t show real domain-level metrics — plenty of marketing, but little proof.3. Why I Ultimately Chose ZoolatechThe decision wasn’t just “they looked solid.”
It was specifically because of:

• Transparent engineering breakdowns — they literally showed how many dev hours specific healthcare features normally take.
• Experience with EMR/EHR integrations like Epic and Cerner (many outsource companies claim this but never demonstrate it).
• A clear security model mapped to HIPAA, not just generic “we are secure.”
• Flexible scaling — from a 3-person team to a 25-person squad in 30 days.

Also, they asked better questions during discovery than any other vendor. Instead of “What features do you want?”, they asked “What patient outcome are you trying to improve?”
That’s the mindset I wanted.4. Questions to the communityI’m curious:

• What metrics do you use when comparing vendors for healthcare software development?
• Does anyone else evaluate companies based on measurable outcomes (e.g., reduction in admin time, patient throughput, compliance risk)?
• How do you judge engineering maturity without falling for glossy case studies?

I’d love to hear which companies you consider the real top healthcare technology companies today — especially ones with proven results, not just strong branding.
