What is custom app and website development?
Nordic MarTech builds custom web apps, websites, PWAs, funnels and AI knowledge bases for businesses that have outgrown generic templates. Every build is a €5,000 fixed base build: 50% (€2,500) upon kickoff, 50% (€2,500) upon staging sign-off. Optional hosting & maintenance is €295/mo. Delivery runs discovery, architecture and copy, build, then launch.
Why generic templates fail
Most marketing tools are built for a generic business, then stretched to fit yours. Landing pages can't test the offer you need to test, and internal tools don't talk to your CRM. A custom app or website is built around how you actually work.
What we build
- →Micro apps. One job done properly: a calculator, configurator, quote tool or audit widget.
- →Custom applications. Full builds wired into your CRM and marketing stack, replacing a manual process.
- →Websites. Conversion-focused, fully responsive sites in Webflow or custom code. Structured data (schema) is built in from the start, so search engines and AI answer engines can read them.
- →Progressive Web Apps (PWAs). Installable, fast and usable offline, with no app store gatekeeping the release.
- →Sales funnels, landing and bridge pages. The full path from ad click to booked call, with bridge pages that carry intent between the two.
- →AI knowledge bases. Structured, source-backed knowledge bases built from your websites, documents and product data, so answer engines and your own assistants can read and cite them.
What it costs

€5,000 fixed base build50% (€2,500) upon kickoff, 50% (€2,500) upon staging sign-off prior to production deployment · full PWA site conversion included · optional hosting & maintenance €295/mo- Built around your actual workflow and wired into the CRM and marketing stack you already use
- Discovery, architecture and conversion copy included, not quoted as extras
- Full ownership of the code, copy and architecture on final invoice settlement
Full PWA site conversion, included in every build:
- Your existing site as an installable app on the home screen, with no app store review
- Works offline and on weak connections, so a dropped signal doesn't end the session
- One build that runs on iOS, Android and desktop
- Push notifications enabled, so you can reach people after they've left the site
- Faster repeat visits through cached assets
- Your hosting stays where it is — nothing has to move
Optional hosting & maintenance, €295/mo, covers:
- Hosting, deployment and SSL
- Ongoing technical support — direct, no account manager in between
- Updates, maintenance and security patching
- Live push notifications
- Monitoring and uptime checks
Website Design & Build
€5,000 fixed base build50% (€2,500) upon kickoff, 50% (€2,500) upon staging sign-off prior to production deployment · optional hosting & maintenance €295/mo- Conversion-focused site in Webflow or custom code, fully responsive on phone, tablet and desktop
- Structured data (schema) integrated from the start, not bolted on after launch
- Discovery, architecture and conversion copy included, not quoted as extras
- Full ownership of the front-end, styling and copy on final invoice settlement
Optional hosting & maintenance, €295/mo, covers:
- Platform hosting included — the Webflow site plan or equivalent sits inside the €295, so there is one infrastructure invoice
- Deployment and SSL
- Ongoing technical support — direct, no account manager in between
- Updates, maintenance and security patching
- Monitoring and uptime checks
Websites and apps are priced the same way. Optional hosting and maintenance is €295/mo per property, billed from launch. App builds include a full PWA conversion of your existing site rather than quoting it separately. Micro apps, funnels and landing pages sit inside the same engagement and are scoped after discovery.
Add-On: Custom Claude Skills (SKILL.md)
A Claude Skill is a deterministic recipe that teaches an AI assistant to do one job your way, every time. Examples: answer support questions in your tone, draft proposals to your structure, or follow an internal SOP. We build them from your own PDFs, SOPs, brand books and documentation, so the output is grounded in your material.
They drop into your Claude workspace, Claude Code or your own agent, and they're yours to keep. Three are included free in month one of the flagship AI SEO engagement and in M2 and M3 packages.
How the process works
- Discovery & systems audit. We map your CRM, marketing stack and the specific workflow or conversion problem to solve.
- Architecture & copy. Scoped against a real goal. The words are written alongside the structure, because placeholder copy converts like a placeholder.
- Build. Custom development, integrated with your existing marketing and sales stack.
- Ship, host & support. Deployed after your staging sign-off. On the optional €295/mo retainer, fully hosted with ongoing technical support.
What's included
- →Everything listed under What we build, scoped after discovery
- →Optional Custom Claude Skills (from €300)
- →Conversion copywriting, written by a person
- →Marketing automation and internal tooling
- →Hosting, deployment, SSL and ongoing technical support on the optional €295/mo retainer
- →Published pricing: anything outside the scope above is quoted in writing before it starts
- →Direct access to the person doing the work, not an account manager
- →Full ownership: code, copy and architecture transfer to you upon final invoice settlement, with no proprietary vendor lock-in
How we write and check
AI speeds up research, first drafts and boilerplate, but nothing ships unread. Every page of copy is written or rewritten by a person who understands the offer. Everything is checked three times before launch: for accuracy, for the words, and on a real device.
Larger builds are delivered with a vetted network of specialist partners, each chosen for one discipline. You're told upfront who is doing what on your project.
Common Questions
Do you build websites as well as apps?
Yes. Websites are priced exactly like app builds: €5,000 fixed, 50% (€2,500) upon kickoff and 50% (€2,500) upon staging sign-off prior to production deployment. Optional hosting and maintenance at €295/mo per property includes the platform hosting itself (the Webflow site plan or equivalent).
What counts as a "custom app"?
Anything from a focused micro app that does one job well to a full custom application or an installable PWA that works offline. Funnels, landing pages, bridge pages and AI knowledge bases count too, all scoped to your actual workflow.
Can you convert my existing website into a custom web/mobile app?
Yes. Every custom build includes a full PWA conversion of your existing site, plus custom workflow integrations and native-feeling app features. It installs on iOS, Android and desktop without App Store fees or review delays.
Is hosting and maintenance included?
No, not in the €5,000 build. Hosting and maintenance is optional at €295/mo per property: hosting, deployment, SSL, updates, live push notifications, monitoring and direct technical support. Your existing web host can stay where it is, because the PWA and custom app layer sits on top of your current website. If you would rather host and maintain the build yourself, the code is yours on final invoice settlement.
Do you integrate with our existing CRM/marketing tools?
Yes. Your existing CRM and marketing tools are the starting point of the discovery phase, and the build is designed around what you already use.
Can you redesign an existing tool instead of building new?
Yes. Discovery covers what already exists, so a rebuild or extension of a current tool is scoped the same way as a new build.
What is a Custom Claude Skill?
A Custom Claude Skill is a deterministic instruction file that teaches an AI assistant to do one job your way, every time. We build them from your own PDFs, SOPs and documentation. €300 for one, €750 for five, €1,250 for ten. Three are included in month one of the flagship AI SEO engagement, and the M2 and M3 packages each include three custom Claude Skills.
Is the copy written by AI?
No. AI assists with research and first drafts; the copy that ships is written or rewritten by a person, then checked three times before launch. We tell you plainly where AI was used in a project.
