# How a SaaS company got an internal AI research tool in 1 week instead of hiring 2 engineers

A SaaS company was about to hire 2 engineers to build an internal AI research tool. We built it in 1 week instead. It took 20 hours a week of manual research off the team, with no new hires, and the company owns everything that was built.

## What was the problem?

The team was spending 20 hours a week on manual research, and the plan on the table was to hire 2 engineers to build an internal tool for it.

## What did we build?

An internal AI research tool that takes over the gathering and first-pass summarizing the team had been doing by hand, with people reviewing the output. It was handed over with documentation so the company’s own engineers can maintain and extend it.

## What changed?

Before and after:

| Measure | Before | After |
| --- | --- | --- |
| Manual research time | 20 hours a week | 20 hours a week saved |
| How it got built | Plan to hire 2 engineers | Built in 1 week, no hires |

- **20 hrs/week**: of manual research saved (SaaS) ([case study](https://workflowpal.com/case-studies/saas-internal-ai-research-tool/))

## What should you know before building something similar?

- Decide what a good research output looks like, with two or three real examples, before any code is written.
- Make sources visible in every answer so people can check the work quickly.
- Hand over to a named owner on your team, even if you keep support. Internal tools die without one.

## Could this work for you?

If your team does similar work by hand, probably.
