01
Recognize this situation?
You pay per click, but the page is slow to open on a phone and part of the traffic leaves before seeing the offer.
The form submits, but the lead never reaches the CRM, and nobody knows which ad it came from.
Every new campaign depends on the IT queue or on a page builder that limits the layout.
The numbers in the ads dashboard and in analytics do not match, and you cannot trust the cost per lead.

What we deliver
Hand-coded campaign page

One page with the offer, proof, frequently asked questions and a single call to action that matches the ad, in static, responsive HTML, with no theme and no page builder.
Integrated form

A form with server-side validation and anti-spam protection that delivers the lead by email, by webhook or straight into your CRM.
Tracking in place
Tracking in place
Pixels and conversion events checked before publishing, and UTM parameters preserved so every lead reaches the CRM with the ad it came from.
Structure for A/B tests
Structure for A/B tests
Headline, offer and call-to-action variations built as components, so tests run with the tool your team already uses.
Measured performance
Measured performance
Optimized images, self-hosted fonts and minimal JavaScript, with Lighthouse mobile measured before the campaign, so paid clicks are not lost while the page loads.
Publication and repository
Publication and repository
The page published on your domain or subdomain, with HTTPS, and a repository with instructions to create new variations and campaigns.
No published client case or campaign result for this service yet: we propose to start with one page as a fixed-scope project. The closest thing we have built is this website, on the same practices: Astro, Tailwind CSS, static HTML and self-hosted fonts.

Who it is for and who it is not
Landing page development is the building of a single campaign page designed for one offer and one action: fill in a form, book a call or buy. Hire it when you invest in paid media and need a page that loads fast, records every conversion and lets you test variations, without depending on the corporate website or a page builder.
A good fit for
Marketing and paid media teams that run campaigns on Google Ads or social networks and pay per click.
B2B companies that need one page per offer, event or launch, with the lead reaching the CRM.
Agencies that want a technical partner for the pages while they handle creative and media.
Businesses that want to validate an offer before investing in a larger project.
Not a fit for
Anyone who needs a permanent presence with several pages and SEO: that is the scope of the website development service.
Anyone looking for media buying, creatives or copywriting: we deliver the page and the measurement, not the campaign.
Anyone who wants to edit the layout alone every day: a page builder serves that use better.
Anyone expecting a guaranteed conversion rate: it also depends on the offer, the audience and the ad.

Technical details
How we use AI with governance, the decision comparison and the stack
AI with governance
AI speeds up the production of the page and its variations, but what goes live passes through human review and the same checks as any of our projects.
In the buildAI coding agents (Claude Code, Codex, Cursor, Copilot, OpenCode) implement sections and variations from the approved brief.
Copy variationsAI drafts alternative headlines and calls to action; you approve what will be tested.
What humans reviewThe offer, the claims, the numbers and every published change go through a person.
Checks before publishingPerformance, accessibility, form submission and the firing of conversion events.
Lead dataIt goes only to the tools you choose and is never used to train models.

Frequently asked questions about Landing Pages
How much does a custom landing page cost?
The cost depends on four factors: who writes the content, the number of sections and variations, the form integrations (CRM, email, webhooks) and the tracking required. We do not publish prices: the proposal follows the briefing, as a fixed-scope project, in USD or BRL. It is our entry-level service, and the component base is reused in the following pages.
How fast can a landing page go live?
The timeline is set in the proposal, after the briefing, because it depends on three things: content that is ready or still to be produced, the number of integrations and approval time on your side. A page with approved copy and a simple form moves faster than one with a CRM, several variations and legal review. We state the publication date before starting, together with the scope.
Does the page come with pixels and conversion tracking set up?
Yes: we set up the pixels and conversion events of the platforms the campaign uses, such as Google Ads, Meta Ads and GA4, and keep the UTM parameters all the way to the lead. Before publishing, we check every trigger with a test submission. The ad and analytics accounts belong to your company; we work with the access you grant.
Can we run A/B tests on the landing page?
Yes: the page is built with sections and copy as components, which makes it possible to publish variations and split traffic with the testing tool or the ad platform you already use. We deliver the structure and the variations; the test result depends on traffic volume and on the offer. We do not promise a conversion rate.
Who owns the page and the domain?
The domain should be in the name of your company, and at handover you receive the page code in a repository that can be hosted on any static hosting provider. Scope, ownership and confidentiality are set in the contract before work starts. The page is published on your domain or on a subdomain.
Does the landing page integrate with our CRM or email tool?
Yes, as long as the tool offers an API, a webhook or an inbound form: the lead is sent at sign-up, with the source and the campaign parameters. When there is no API, we use an automation workflow, for example with n8n, or email delivery. Related experience: at ADT Solar, we integrated Salesforce and DocuSign into sales workflows.
What does a landing page need to convert paid traffic?
Five things: a clear offer at the top, consistent with the ad; fast loading on a phone; a short form; proof, such as numbers and clients; and reliable measurement of every conversion. We take care of the technical part: speed, form, tracking and the structure for tests. The offer and the traffic are yours, and the combination of the three defines the result.

In the first conversation we learn the offer, the traffic and your tools. A landing page may skip the 1–2 week discovery: with the campaign defined, the fixed-scope proposal comes from the briefing.
