Marketing & Growth

Pages, funnels, and lifecycle, built to convert and measure

Landing-page systems, lifecycle flows, multilingual SEO, and CRO programs run as one rhythm. Pages ship under templates, every test gets a hypothesis, and reporting actually answers the question on the table.

Where this fits

Built for the moments you can't postpone

We don't take work just to take work. This service exists because the problems below are the ones we keep being hired to solve, and the ones we've shipped through more than once.

  • Landing pages take engineering tickets to launch, campaigns get throttled
  • Klaviyo / HubSpot has flows from three different agencies; nobody owns it
  • Going multi-market and SEO / content can't keep up with the localisation
  • Running A/B tests but the call is always vibes, no real measurement plan
  • Attribution is broken; nobody trusts the channel ROAS in the dashboard
  • Need a real growth rhythm, not another deck full of 'frameworks'

What we ship

Solutions, not slide decks

Each line below is a real deliverable shipped on past engagements, with an honest scope and a metric where it makes sense.

01 / Scope

Landing-page system

A reusable component library so marketing can ship a new page in hours, A/B test it, and roll it back without engineering, across campaigns, industries, and locales.

4–12 pages / month rhythm

02 / Scope

Lifecycle & retention

Klaviyo or HubSpot built around the buyer's actual lifecycle: welcome, browse, abandoned cart / quote, win-back, post-purchase, churn save. Segmented and tested.

03 / Scope

Multilingual SEO

Content ops, hreflang, structured data, and a market-by-market keyword strategy. Translation done by humans, briefs done by us, schema generated alongside the copy.

04 / Scope

Conversion-rate optimisation

Hypothesis-led A/B program, each test has a written brief, a measurement plan, and a rollback. We don't run experiments without an instrumented funnel underneath.

05 / Scope

Analytics & attribution

GA4, GTM, Search Console, Triplewhale (for DTC), wired so leadership sees one number, not five contradictory ones from five dashboards.

06 / Scope

Weekly growth digest

A short, written digest every Monday: what shipped, what moved, what didn't, what's next. No slop, no 'engagement metrics', no AI-generated filler.

Weekly, 5-min read

Common questions

Honest answers, no sales theatre

Are you a 'growth agency' or do you actually build the pages?

We build the pages. The reason this discipline lives at TengenX is exactly that: most growth agencies hand you a strategy deck and a Notion doc, then wait six weeks for an in-house engineer to ship the page. We own the build, the measurement, and the iteration loop end-to-end, that's why the rhythm holds.

What does 'hypothesis-led testing' actually mean?

Every A/B test ships with a written one-pager: what we believe, what we'll change, the metric that decides, the minimum sample size, the rollback path. No more 'red button vs blue button, the winner is whichever feels nicer'. We share the brief before the test goes live and the readout after.

Can you work with our existing in-house team / agency?

Yes, common setup. We typically own pages + lifecycle + measurement, and partner with an in-house brand / content team or a paid-media agency. The weekly digest is the integration surface, everyone reads the same one number.

How do you handle multilingual SEO?

Briefs and schema are produced by us; translation is done by human translators (we contract per market or use yours). hreflang, locale URLs, internal links, and Search Console properties are set up at the foundation stage so each new locale ships under the same template. Wowflow runs three live markets on this model.

What about attribution, what if our data is a mess?

That's almost always where we start. Audit existing GA4 / GTM / Klaviyo / HubSpot, fix the events that are firing wrong, stand up a weekly digest off the cleanest source of truth available, and only then start running tests on top. We won't run a CRO program on broken measurement and pretend the numbers are real.
