RE: CT startup error this morning
Spend less time piecing together difficult service cases.Untangle complex service cases
We’re building a better way for service teams supporting complex medical equipment to gather the right information, build a clear case history as the investigation develops, and preserve the resolution and reasoning for future cases.We’re building an AI assistant for technical support and service teams working with medical and lab equipment. It turns scattered information into a developing case so teams can solve faults faster.

- Installed firmware (v4.2.1) was not compatible with the replacement controller board (rev C).
- Action taken
- Firmware updated to v4.3 on site, following SB-24-017. Morning startup checks passed.
- Steps
- Linked the site email, startup log, service record and manual section.
- Compared installed firmware with the board revision (remote).
- Updated firmware to v4.3 on site, per SB-24-017.
- Re-ran morning startup checks — passed.
- Reasoning
- The error began after the board replacement. The log, the board revision and SB-24-017 pointed to firmware compatibility, which the remote comparison confirmed — the same cause as case 1842.

Resolution
Confirmed- Confirmed cause
- Installed firmware (v4.2.1) was not compatible with the replacement controller board (rev C).
- Action taken
- Firmware updated to v4.3 on site, following SB-24-017. Morning startup checks passed.
- Steps
- Linked the site email, startup log, service record and manual section.
- Compared installed firmware with the board revision (remote).
- Updated firmware to v4.3 on site, per SB-24-017.
- Re-ran morning startup checks — passed.
- Reasoning
- The error began after the board replacement. The log, the board revision and SB-24-017 pointed to firmware compatibility, which the remote comparison confirmed — the same cause as case 1842.

Developing service case
How much does it cost your team to piece together difficult service cases?
Estimated time spent
20 hours / month
≈ £1,200 / month
in service time
20 hours × £60/hour = £1,200/month
Assumes an illustrative £60/hour loaded engineering cost. Actual costs vary.
Estimated annual cost of gathering context
£14,400 per year
240 hours a year
of service-team time
Based on your inputs and an illustrative £60/hour loaded service cost. Actual costs vary.
How this is calculated
20 cases × 1 h × 12 months = 240 hours 240 hours × £60/hour = £14,400/year
Start with one service workflow.
We’re starting with specialist medical-equipment distributors and OEM service teams. We’ll work with you on a focused pilot using the information your team already works with.

We’ll work with you on a focused pilot using your existing service information.
- One product line
- Real service cases
- Find where the information effort can be reduced
Why I’m building this
I previously managed a hospital in a remote area, where equipment downtime could have serious consequences for patients and staff.
Since then, speaking with medical-equipment distributors and OEM service teams has shown me the other side of the problem: how difficult it can be to bring together everything needed to resolve a complex service case.
Have a service workflow that takes too much effort to piece together?Where do your difficult service cases get stuck?
Start with one product line and a set of real service cases. We’ll see where the information work around those cases can be reduced.Start with one product line and a set of real service cases. We’ll explore where time is lost gathering context and moving investigations forward.
