Why Building an Internal AI Platform Costs More Than You Think...

Building Your Own AI Platform? Think Twice Before Building In-House

Every engineering team reaches a point where AI starts showing real business value.

The next question is almost always:

Why don't we build it ourselves?

It sounds reasonable.

But building an AI platform involves far more than connecting to an LLM.

What You're Actually Signing Up For

When you build internally, you also own:

Development costs
Infrastructure
AI model costs
Security
Monitoring
Maintenance
Continuous improvements

A Prototype Isn't the Product

Getting a demo running is relatively easy.

Getting it production-ready requires:

AI Engineers
Backend & Frontend Developers
DevOps
QA
Security
Product Management

Eventually, your internal AI tool becomes another product your engineering organization must support.

The Cost Nobody Talks About

AI infrastructure keeps evolving.

Your team will constantly deal with:

Model updates
API changes
Prompt improvements
Reliability testing
Performance optimization
Scaling
Security patches

The work never really ends.

The Three Permanent Phases

Build
Operate
Improve

Every successful internal AI platform lives inside this cycle forever.

The Real Question

Instead of asking:> Can we build it?

Ask:> Should we build it?

If your goal is helping engineers investigate incidents faster, your best investment may be focusing engineering time on customer-facing products—not AI infrastructure.

That's why Build vs Buy is ultimately an economic decision, not just a technical one.

What would your team choose?

Build or Buy?

Stop Measuring AI by Lines of Code. Measure It by Engineering Hours Saved.

Whenever engineering teams evaluate AI tools, the first question is usually:

"How much faster will developers write code?"

I think that's the wrong question.

A better question is:

How much engineering time are we wasting investigating production incidents?

Because that's where a surprising amount of money quietly disappears.

Let's do a simple calculation.

No complicated ROI formulas.

No marketing buzzwords.

Just numbers.

Imagine Your Engineering Team Looks Like This

Team size: 50 engineers
Production incidents: Around 180 per year
Engineers involved in each incident: 5
Average investigation time per engineer: 2.5 hours
Average engineering cost: $80/hour

Nothing unusual.

In fact, these numbers are fairly common for many growing SaaS companies.

Engineering Hours Lost Every Year

Each production incident requires:

5 engineers × 2.5 hours = 12.5 engineering hours

Across 180 incidents:

180 × 12.5 = 2,250 engineering hours every year

Read that again.

2,250 engineering hours.

That's time spent:

Understanding production failures
Jumping between logs
Looking at dashboards
Checking traces
Reading deployment history

Instead of:

Shipping new features
Improving reliability
Reducing technical debt
Building products customers love

Now Translate Those Hours Into Money

If engineering costs average $80/hour:

2,250 × $80 = $180,000/year

That's $180,000 spent just investigating incidents.

And for many organizations, nobody actually measures this cost.

Maybe We're Measuring AI Incorrectly

Most AI discussions focus on:

Writing code faster
Autocomplete
Pull request generation

Those are valuable.

But once software reaches production, another problem begins.

Finding the root cause.

And that's often where engineering teams lose the most time.

Why We Built FixBugs

This problem is exactly why we're building FixBugs.

Instead of making engineers jump across logs, traces, code, deployments, alerts, and documentation, FixBugs automatically gathers the debugging context and helps teams reach the root cause much faster.

What If Investigation Time Drops By 50%?

Current effort:

2,250 engineering hours/year

With a 50% reduction:

1,125 engineering hours saved

Financial impact:

1,125 × $80 = $90,000/year

More importantly...

Those hours go back to engineering teams.

Not by replacing engineers.

But by helping them spend more time building instead of investigating.

Four Questions Every Engineering Leader Should Ask

Instead of asking:

"Does this AI tool generate code?"

Ask:

How many production incidents do we investigate every year?
How many engineering hours do they consume?
What is one engineering hour worth?
How much of that time could realistically be recovered?

Those answers build a much stronger business case than any marketing claim.

Final Thoughts

AI ROI shouldn't be measured by how many lines of code it generates.

It should be measured by how much engineering time it gives back.

For many organizations, the biggest opportunity isn't writing software faster.

It's spending less time figuring out why production broke.

Sometimes the highest ROI doesn't come from hiring more engineers.

It comes from helping the engineers you already have spend more time building—and less time investigating.

Discussion

How does your engineering team currently investigate production incidents?

Do you actually measure the engineering hours spent on incident investigation?

I'd love to hear how other teams approach this.
