Danny Birt Danny Birt Est. 2017
Direct Response Copywriting — Est. 2017

Founders who refuse to sound like everyone else.

Conversion copy engineered to move a specific visitor segment from skeptic to buyer. Verified across 180+ rewritten pages since 2017 — average lift, 2.4×.

§ 01 — The Record

Three pages I rewrote. Three lift numbers.

A scanning founder sees proof in under ten seconds. Here it is — recent engagements, metrics first, page type and industry underneath. No vanity, no vague "we grew conversions" claims. Specific pages, specific lifts, specific verticals.

  1. 2.7× on-page conversion lift
    SaaS · Pricing page rewrite

    Repositioning a $14M ARR analytics tool around a single buying committee.

    Old page treated three buyer personas as one. We rewrote the headline, mechanism, and proof stack around the economic buyer — and shipped a 64-day A/B test that paid for the engagement inside the first billing cycle.

  2. 3.1× checkout completion rate
    DTC · High-ticket supplements · Subscription PDP

    Killing the founder-essay and replacing it with a 9-block proof argument.

    The old PDP read like a personal journal. We replaced it with an Offer + Proof + Mechanism sequence sourced from 14 customer interviews, and watched checkout completion climb for ten straight weeks.

  3. 1.9× qualified discovery-call bookings
    B2B services · $22K average contract · Sales letter

    Turning a 4,200-word founder manifesto into a 1,800-word sales argument.

    Cut 56% of the prose, kept every piece of proof, and rewrote the lead to lead with the mechanism instead of the founder's origin story. Bookings doubled; the founder kept the parts of the original it deserved.

§ 02 — The Method

Offer + Proof + Mechanism.

Every rewrite gets run through this editorial lens before a single headline is drafted. It's not a vibe. It's a checklist for whether a page deserves to ship.

I.

Offer.

If the offer isn't specific, the page can't be persuasive. I pressure-test the promise — the price point, the deliverable, the buyer — until it's small enough to defend in one sentence. Vague offers get rewritten before any copy is touched.

II.

Proof.

Then I demand receipts. Customer interviews, third-party data, named logos, screenshots, dated results — proof that the offer has been honored by someone other than the founder. Forty-plus deep-dive interviews, transcribed and archived, become the raw material.

III.

Mechanism.

Finally, I name how it works. A mechanism is the missing piece of logic that lets a skeptic go from "sounds nice" to "yes, I see why this would work for me." No mechanism, no conversion. Every rewrite ships with one, stated explicitly, somewhere above the fold.

The framework has been taught inside three private Slack communities, and underpins every rewritten page since 2019. It's also the editorial spine of The Birt Brief.

§ 03 — The Record, Continued

What clients say when the lift is in the dashboard.

Quotes tied to a metric or a named outlet — not generic praise. Plus the 5.0/5.0 across 87 verified Clutch and Upwork reviews, and the press citations that put this work on the radar of CMOs at companies you'll recognize.

"We shipped Danny's rewrite on a Tuesday. By Friday the A/B test had cleared the 95% confidence threshold and we hadn't touched design. He's the only writer I trust with a paid-traffic landing page."

Head of Growth, Series B SaaS 2.7× lift on pricing page · 64-day test

"He runs customer interviews the way a strategist should. Three weeks later our PDP had proof I didn't know we had, and the checkout graph climbed for ten straight weeks."

Founder, DTC supplements 3.1× checkout completion

"I'd worked with three copywriters before. Danny was the first one who told me the offer was the problem, not the prose. We fixed the offer, then he wrote the page. Bookings doubled."

CEO, B2B advisory firm 1.9× qualified discovery calls

"The only freelancer I refer clients to without a second thought. Senior judgment, no hand-holding required, and the lifts show up in the dashboard."

§ 05 — How The Work Gets Scoped

Three engagement shapes. One of them fits.

Starting investments live around the $8K threshold — that's the floor where this work makes sense for both sides. Smaller budgets usually mean the offer isn't ready yet; if that's you, the audit call will tell you so honestly.

Is this a fit?

  • You're spending real traffic dollars on a page that's under-converting.
  • You have a defined offer with a clear price point above $1,500.
  • You're willing to run an A/B test and let the data decide.
  • You need a redesign before the copy can be evaluated.
  • You want copy written before the offer is defined.

Current capacity: 6 clients per quarter. The waitlist sits at roughly three weeks; if the next slot matters, the audit call is the fastest path onto the calendar.
