B2B SAAS · DATA INTELLIGENCE

EM360: from 0.12% to 7% conversion — no extra ad spend.

The challenge

EM360 was spending heavily on paid traffic but converting just 0.12% of visitors into users. The funnel felt modern, but nothing was tested. They suspected speed, but didn’t have the data to prove it.

What we did

Ran a full AI audit: predictive heatmaps, speed analysis, funnel diagnostics. AI-generated 20+ headline variants and tested them against the original. Restructured the funnel to reduce friction on mobile. Fixed page speed issues costing 7% of conversions per extra second of load time.

The result

Conversions jumped from 0.12% to 7% — a 58× lift. Revenue compounded from $48k/yr to multiples of that, with zero extra ad spend.

Why it worked

AI gave us experiment volume. 13 years of pattern recognition told us which experiments to prioritise, and when the AI’s “winners” were actually false positives. Speed fixes freed the conversions the funnel was already earning but losing to abandonment.

B2B CREATIVE · ANIMATION STUDIO

Flikli Animation: a landing page at 0.4% — rebuilt with AI, tested to transformation.

The challenge

Flikli’s landing page looked beautifully designed but converted at 0.4%. Every week of that was wasted paid traffic and ghosted leads. The existing copy had never been tested against an alternative.

What we did

Ran AI-generated copy tests on the hero section and primary CTAs. Rebuilt the funnel with data-backed layouts guided by predictive heatmaps. Optimised page speed and mobile experience — 68% of their traffic was on a phone the old design ignored.

The result

Conversion rates transformed the business: the same traffic budget now delivers multiples of the leads it did before, and the sales team sees enough pipeline to be selective.

Why it worked

The copy that the designer wrote two years prior had never been tested. AI ran 20+ variants in minutes. The best one wasn’t the most creative — it was the one that named the visitor’s exact problem in their exact language.

EVENTS · STUDENT MARKETING

Freshers Festivals: a landing page converting at 46.82%.

The challenge

Freshers Festivals needed more brand sponsors for their student-facing events. The old funnel treated every visitor the same and left sponsorship inquiries scattered across email threads and phone calls.

What we did

Built a conversion-engineered landing page from the ground up. AI-generated copy variants. Psychology-led structure positioning the audience of Millennial students as the value — not the events. Automated the first-contact sequence so interested sponsors self-qualified.

The result

46.82% of visitors requested a quote. A landing page that outperformed every benchmark the industry uses for cold traffic.

Why it worked

The old page sold the festival. The new page sold the audience. Sponsors don’t buy events — they buy access to a specific demographic. We named that access in the language sponsors already used internally.

ECOMMERCE · HOME & INTERIOR

Super Area Rugs: 216.29% revenue increase in 37 days.

The challenge

A leading US-based rug retailer was running healthy traffic but flatlining on revenue growth. Ad spend couldn’t scale profitably because the site leaked conversions at every checkout step.

What we did

Deployed a 37-day conversion sprint: AI-led copy testing across category and product pages, a rebuilt promotional funnel around a signature Black Friday push, and friction reduction through the checkout. Every change tied to a revenue-per-visitor target.

The result

Monthly revenue jumped 216.29% in 37 days — from the same traffic base, on the same catalogue.

Why it worked

Rug buyers need certainty: will it fit the room, will it feel right, will it arrive on time. We tested messaging around each worry and made the winners the default. AI ran the tests — 13 years of CRO pattern recognition picked which worries mattered most.

ECOMMERCE · HEALTH & WELLNESS

Enzymedica: from 2.2% to 11.3% conversion — 5× more revenue from the same traffic.

The challenge

Enzymedica was converting just 2.2% of visitors into buyers. The traffic was high-intent, but the funnel wasn’t capturing it. Every extra percentage point of conversion meant six-figure revenue upside — so the stakes for the tests were real.

What we did

Deployed a full AI-led CRO sprint: predictive heatmaps pinpointed where attention was being lost, AI-generated headline and CTA variants ran against the originals, and the checkout was restructured to remove friction on mobile. Every winning change was retested to rule out novelty effects before it shipped.

The result

Conversion rate climbed from 2.2% to 11.3% — a 5.1× lift. No extra ad spend. Same traffic. Roughly 5× the revenue.

Why it worked

Health buyers need two things before they commit: proof that the product works, and reassurance that the brand is credible. The winning variants led with specific claims tied to scientific backing, placed social proof where skepticism peaked, and simplified the path to checkout on mobile.

NONPROFIT · VEHICLE DONATIONS

Donate For Charity: 494.64% more donations in 30 days.

The challenge

Donate For Charity helps donors contribute vehicles to nonprofits across the US. Their existing funnel lost potential donors between the decision and the paperwork. The emotional pull was there — the commitment mechanism wasn’t.

What we did

Built a new landing page from scratch using psychology-first CRO techniques. Framed the ask around the mission and the families served — not the transaction. Rebuilt the sales funnel so donors committed in stages, with friction removed at each drop-off point. AI-generated copy tested emotional framing against transactional framing.

The result

Donations increased 494.64% in 30 days. Same traffic sources, same charity partners — a landing page engineered around how donors actually decide.

Why it worked

Charitable giving is emotional and the old copy sold the process. The winning version sold the impact — who this helps, what happens next, why this car matters — then asked for the donation when the emotional commitment was strongest.

B2B · MANUFACTURING

Helix Binders: monthly revenue nearly tripled in 11 days.

The challenge

Helix Binders manufactures custom binders for B2B clients. Their quote request flow was buried behind a generic product catalogue. Buyers who were ready to order often couldn’t figure out how — and the sales team didn’t know they existed until the lead had gone cold.

What we did

Built a dedicated lead-capture landing page aimed at volume buyers. AI ran copy variants against each buyer persona. The request form was cut to the minimum viable questions. Thank-you pages shipped with a fast-track callback offer to shorten time-to-quote.

The result

In 11 days, leads worth 2,603 units came in — nearly tripling monthly revenue against the previous period.

Why it worked

B2B buyers with budget in hand don’t want to browse. They want to answer three questions (can you do the spec, by when, at what price) and hit send. The new page asked those three questions in the order buyers thought about them. The sales team closed against volume they’d never seen before.
