# GTM engineering case studies

What we built for each customer and what changed afterward, measured in their own data. Each case study says where its numbers come from and how they were counted.

## Results at a glance

| Customer | Industry | What we built | Headline result | Timeline |
| --- | --- | --- | --- | --- |
| [Coastal Recruiting](https://getaob.com/coastal-recruiting-case-study) | Recruiting | Candidate outbound engine: recruiter-calibrated scoring, fresh candidate data, recruiter-voice email, Slack reply desk | Accepted intros up 4.7x (72 in April to 340 in August), about 10 a day | April to September 2026 |

## How we report results

Every number on these pages comes from the customer's own systems, pulled on a date we state. We define each metric in plain terms before we count it. At Coastal, an accepted intro only counts once a recruiter clicks approve in Slack, and out-of-office replies never count as interest.

Quotes come from recorded calls and written messages, lightly edited to remove filler words. If a result depends on something outside our work, we say so on the page.

## Who else we've built for

Beyond Coastal Recruiting, we've built inbound, outbound and enrichment systems for Antimetal, SuperDial, Rubie, Enata and others across SaaS, AI, healthcare, legal tech and private equity. The [full customer list](https://getaob.com/#customers) is on the homepage, and [what we build](https://getaob.com/systems) covers the systems behind these results, from [Clay builds](https://getaob.com/clay-agency) to [signal-based outbound](https://getaob.com/outbound-agency).

### How does OneGTM measure case study results?

Quotes come from recorded calls and written messages, lightly edited to remove filler words.

### How long does a GTM engineering engagement take to show results?

It depends on the motion, but at Coastal Recruiting the first lift showed up within weeks, and by month four the outbound engine was producing interested candidates every day without anyone pushing it.
