Case study · Hallway · eight weeks

This is what a sprint looks like.

A scroll-through of one real sprint, start to finish — from a founder with no pipeline to first paying pilots. Three players run it. Here's who.

H
Harper · founder
The founder.

Knows the product, doesn't know how to sell it. Makes the calls only she can make.

R
Reeve · operator
Our human operator.

Runs the sprint end to end. The one Harper Slacks. Writes in her voice, red-pens her own drafts.

Atlas · orchestrator
Our orchestrator.

Non-human. Plans channels per segment, drafts variants, keeps attribution, never sleeps.

Week 0 · where Harper started

Harper had a product. Nothing else.

Built solo over 14 months. Shipped three weeks ago. Fifty trial installs, zero paying teams — and about six months of her own savings left to turn this into a company.

pipeline“I don't know which lawyers to talk to.” — Harper
Week 1 · kickoff call

We listened first.

A 45-minute call with Harper and our operator, Reeve. Three things came out of it — none of them could have been guessed from the website.

Reeve · operator
notebook · kickoff
the real pitch isn't "answer calls" — it's "never lose a new-client call again." that missed call is worth $3k in PI, $8k in family law.
solo lawyers answer their phones. they don't read cold email. if we're not calling them, we're invisible.
she won't talk to anyone who sounds like "sales." every opener goes through Harper first.

ICP · week 1

We fingerprinted the buyer.

Atlas drafted four fields. Harper corrected one — and that one correction changed the rest of the sprint.

Segment · week 2

Three practice areas, three pitches.

A $3k missed call means something different to a PI firm than to family law. Atlas cut the list by practice area. Reeve named each segment and threw out the noise.

Messaging · week 2

We wrote the message three ways.

Atlas drafted three openers. Two were generic. One got sharpened on a single note from Harper.

You missed 7 calls last Tuesday. That's ~$21,000 in PI intake. We can catch the next ones.
Offers · week 3

We priced three offers. One closed.

Annual, pilot, pay-per-booked-call. Atlas modelled the math; Reeve picked the one a small-firm partner can sign without asking anyone.

Channels · week 3

For this buyer, AI calls win.

Lawyers answer their phones — they have to. Email lands in a graveyard; LinkedIn is for law students. Atlas weighted it, Reeve approved.

The founder pulls the trigger.

We don't send a single message without sign-off. One button. One click.

Week 8 · what Harper got

Harper's first ten paying firms.

More than customers: the answers a founder needs before they can scale. Who the buyer actually is. Which message lands. Which channel converts.

The buyer

Managing partner at a 1–3 attorney firm — not the office manager. Signs same week as demo.

The message that worked

Name the number. “You missed 7 calls last Tuesday — that's ~$21k in PI intake.”

The channel that won

AI voice calls. Lawyers answer the phone; everything else was noise.

11 firms × $12k / year · $132k in first-year revenue · and a playbook Harper can run without us
Week 4 · the honest call

And the part most agencies won't show you.

Immigration lawyers didn't convert — wrong buyer, wrong timing. We told Harper to kill that segment, not stretch to hit her number. She did.

Who did what

Three players. One is called Atlas.

You never touch Atlas directly — Reeve drives it for you. But it's worth knowing what it did across the eight weeks.
