Astarte Medical

Astarte Medical

Astarte Medical needed a purpose-built software platform to manage diagnostic data across multiple clinical sites. Upstack led the full development lifecycle — from requirements gathering and system architecture through to testing and deployment. The result was a GDPR-compliant platform that reduced manual data entry by 60% and cut report generation time from hours to minutes.

Working Process

Our Approach

01. Discovery Phase

We deeply analyze your business goals, target audience, and project requirements to create a clear roadmap. This initial research ensures our entire development process aligns perfectly with your vision.

Our team drafts modern, user-friendly UI/UX designs and transforms them into clean, high-performing code. We focus on building a responsive, scalable website tailored to your brand identity.

We rigorously test every feature, link, and page layout across multiple devices and browsers to eliminate bugs. This meticulous quality check guarantees a flawless and secure user experience before going live

Once everything is fully optimized, we safely transition your website from the staging environment to the live server. We handle the entire launch process smoothly with zero downtime for your business.

We provide continuous technical monitoring, regular security updates, and performance tuning to keep your site running fast. Our team is always ready to assist you with any future updates or troubleshooting needs.

CTO

Upstack delivered our inventory management system ahead of schedule with zero critical bugs at launch. What stood out was how clearly they communicated throughout — no surprises, no last-minute scope changes. We've since handed them two more projects."

James Harrington

CTO
London, United Kingdom

Co-Founder

We came to Upstack with a rough idea and a tight timeline. They helped us prioritise the right features for our MVP, built it cleanly, and we went live in 10 weeks. The mobile app currently holds a 4.7 rating on the App Store."

Product Manager

I've worked with three development agencies before Upstack. The difference is they actually push back when your requirements don't make sense — which saves you money and bad code. Refreshingly honest team."

F.A.Q.

Need a Support?

Q: How do I choose the right software development company?
A.

 Look for a team that asks questions before making promises. A good development partner will take
time to understand your business goals, not just your feature list. At Upstack, we start every engagement with
a discovery call to map out requirements, timelines, and budget — before writing a single line of code. Check
their portfolio for projects similar in scope to yours, and ask to speak with a past client if possible.

A.
  •  A custom software development company builds software specifically designed for your business
    needs — as opposed to off-the-shelf tools like Shopify or Salesforce. At Upstack, we design and build web
    applications, mobile apps, internal tools, and integrations from scratch, tailored exactly to how your team
    works and what your customers needs
A. Off-the-shelf software is built for the average business. Custom software is built for yours. It means
no paying for features you don't need, no compromising on your workflow, and no vendor dependency.
Businesses typically turn to custom development when they've outgrown existing tools, need a competitive
edge, or require integrations that standard products can't deliver
A.
  •  Costs vary significantly based on complexity, team size, and timeline. A simple web application or
    MVP typically starts around $5,000–$15,000. More complex platforms with integrations, custom dashboards,
    or mobile components range from $20,000 upward. At Upstack, we offer a free consultation to scope your
    project and provide a transparent quote — no guesswork.
A.
  •  A basic MVP can be ready in 6–10 weeks. Mid-complexity web or mobile apps typically take 3–5
    months. Enterprise-level platforms with multiple integrations may run 6–12 months. Timelines depend on the
    number of features, revision cycles, and third-party dependencies. We provide a detailed project timeline at
    the start of every engagement so you always know where things stand.
