use cases

From goal to proof.

Real Reply engagements run on Symbiosis. For each: the business goal, what stood in the way and what we did, the measures that moved, and delivery far faster and cheaper than a traditional build.

01

Offshore energy · Legacy replacement

A legacy estate the business can change again.

The business goal

Run and change their own applications again, without the legacy platform or scarce specialists.

1 of 8

legacy applications meeting the maintainability bar. Target: all 8 by 2027.

What stood in the way, and what we did

"We cannot maintain it ourselves anymore."

AI agents rebuilt every business rule in plain Python, with automated tests and written documentation.

Maintainability checks passed

0 → 6 of 6

✓ Solved

No rebuilt application had ever reached production.

Building the path to production with the client's IT team, step by step.

Maintainability checks passed

3 of 5 gates

On track

Cleared: testing, logging, monitoring. Next: sign-off, release.

8x

Faster delivery

3 months vs a typical 2 years

12x

Lower cost

versus a traditional rebuild

Every week

Measured, then decided

Continue, change or stop, on evidence

02

Healthcare · Public health provider

More patients stay in care. Clinicians get their time back.

The business goal

Equitable, verified access to community prehabilitation services across the catchment.

25 → 10

patients in 100 who drop out of the prehab pathway. Target reached.

What stood in the way, and what we did

Manual admin work took clinician time.

Referrals read automatically, support matched by AI, check-ins sent in one click.

Clinician time spent on admin

50% → 20%

✓ Solved

Built on synthetic data, outside the provider's live systems.

Built to national health data and identity standards from day one, then connected.

Live systems connected

0 → 3 of 3

✓ Solved

Patient records (FHIR), verified patient identity, secure clinical messaging.

6x

Faster into production

8 weeks vs a typical 1 year

10x

Lower build cost

versus a traditional build

Every week

Measured, then decided

Continue, change or stop, on evidence

03

Industrial machinery · Agentic bug-fixing

Bugs read, fixed and validated by an AI agent.

The business goal

Ship reliable PLC software to customer projects faster, without a developer hand-fixing every bug ticket.

6 → 19

bugs resolved per week, 3× faster. Measured in a one-week trial, one engineer with the AI agent.

What stood in the way, and what we did

Bugs were fixed by hand, one ticket at a time.

An AI agent reads the bug ticket from Azure DevOps, proposes a fix to the team's coding standards, and posts it back for a developer to review and integrate.

Bugs auto-triaged per project

400 → 100-150

✓ Solvev

The same known bug had to be re-checked across every customer project.

A validation agent flags which known bugs still apply to each project, as a ready-to-work checklist.

Fixes validated in parallel

1 → 10-15

On track

Cleared: testing, logging, monitoring. Next: sign-off, release.

3x

Faster bug resolution

19 vs 6 bugs per week

One-week trial

One engineer + AI agent

not a large team

Every week

Measured, then decided

Continue, change or stop, on evidence
