White-label HubSpot, in one paragraph.
Sharp Creations is a four-person HubSpot development team based in Julianadorp, the Netherlands. For marketing and HubSpot agencies we build themes, modules, email templates, landing pages, migrations and integrations, under your name. You send a job and get a fixed price within 1 working day. We don’t approach your clients, and our name doesn’t appear in the code, the emails or the documents you deliver. Prefer fixed monthly capacity, with priority in our planning? That’s possible too.
We work in English and Dutch, on Central European Time, for agencies in the Netherlands, Belgium, Scandinavia and beyond.
Which agencies this works for.
- HubSpot agencies with a full schedule. Your own developer is fully booked or on holiday, and the client doesn’t want to wait.
- Marketing and content agencies without a developer. You do strategy, design and content, and need someone who builds it in HubSpot the way you designed it.
- Web agencies with a HubSpot client. You normally build in WordPress or Webflow and don’t want to lose this job.
What they have in common: the client relationship is yours, and it has to stay yours. That’s what this way of working is set up for.
What we build for you.
Themes and custom modules
A custom theme or a child theme, with modules your client fills in. In HubL, with HubDB where needed.
Email templates
Modular in the drag-and-drop editor, tested in Outlook, Gmail, Apple Mail and dark mode.
Landing pages and templates
Reusable templates with forms that land straight in HubSpot.
Migrations to HubSpot CMS
From WordPress, Webflow or old HubSpot templates to a modern theme, with a redirect per URL.
Implementation for your client
Portal, data model, pipelines and data import, set up the way you agreed with your client.
Workflows and lead scoring
Routing, scoring and follow-up, tested with test contacts before going live.
Your client stays yours.
- We don’t approach your clients. Not during the job and not afterwards.
- Our name nowhere. No credits in the footer, no comments with our name in the code and no sender of ours in emails.
- Contact with your client only if you ask. If you want us to join a call, we do so as a developer on your team.
- You invoice. Our invoice goes to your agency, never to your client.
- The code is yours once the invoice is paid, including the files and the repository.
Do you work with an NDA or a data processing agreement? We arrange it before we start. If we work in your client’s HubSpot portal, we process personal data on your behalf; a data processing agreement is usually needed then.
How a job runs.

Brief
Send a Figma link, an example or a few sentences. A short screen recording works too.
- 02
Fixed price within 1 working day

- 04
QA and delivery
We test against our checklist and deliver with a hand-over note you can forward.
Process and tools.
We adapt to the way you work, not the other way round. How briefs and questions flow, we agree with you. We read designs from Figma or Adobe XD.
We build locally and push changes to a portal with the HubSpot CLI. The code lives in Git, so every change can be traced and your team can carry on later. Colours, fonts and spacing live in the theme settings, not scattered across modules.
Your contact is Reney Kennet, developer and founder of Sharp Creations. You talk directly to the people who do the work.

One number for the four of us. We reply within one business day. Based in Julianadorp; online, or we come to you.
Code quality and QA.
An agency wants work its own team can change later. That’s why we build to fixed standards:
- Modules with clear editor fields, default values and help text, so a marketer never has to touch code.
- No hard-coded text or colours: the brand lives in the theme settings (
theme.json,fields.json). - No inline styles in modules and no scripts that don’t need to be there.
- Accessible: headings in the right order, alt text, keyboard-friendly and with enough contrast.
Before every delivery we run through the QA checklist: browsers and devices, email clients including dark mode, forms that land in the right CRM record, and speed and SEO. The full checklist is on the rates page.
Examples of jobs.
This is what jobs often look like. We describe them in general terms: with white-label work we don’t name clients or agencies.
- A theme from Figma. The agency designs, we turn it into a HubSpot theme with a set of modules the client fills in.
- An email template that breaks in Outlook. We rebuild it as a modular template and test it in the common email clients.
- Old drag-and-drop templates to a theme. The pages keep their URLs, the client gets modern modules.
- A module that doesn’t exist yet. For example a pricing table, a job listing from HubDB or an FAQ with FAQPage schema.
Our own HubSpot work is online by name: nine HubSpot websites, including those for Linea Recta Advocatuur and ARENI Winestorage. So you can see what we build before you send a job.
