UX design

Good design is mostly invisible: people find what they came for and do what they meant to do. We get there by watching how your users behave, then designing around it.

  • A design system with reusable components, colors and type

A good fit if

People drop off before converting, your product feels confusing, or you want to validate an idea before building it.

Organic search keeps sending visitors long after an ad budget runs out. We fix what holds your site back, then build content and authority that search engines and AI answers want to cite.

Common questions

Anything else? Email us at hello@oseie.com.

How much does a website cost?

It depends on what the site needs to do. A small business website and a custom web application are very different projects. After a short call or a few emails about your goals, we send a fixed quote with the scope written out, so you know exactly what you are paying for before we start.

How long does a project take?

A focused business website usually takes a few weeks from kick-off to launch. Larger sites, web apps and mobile apps take longer and are delivered in stages. You get a timeline with clear milestones in your proposal.

Can you work on an existing website or app?

Yes. We regularly take over existing projects to fix performance, redesign key pages, improve SEO or add new features. We start with a review so we understand what is there before changing anything.

Will I be able to update the website myself?

Yes, if you want to. We set up a content management system suited to your team and show you how to use it. If you would rather not touch it, we can handle updates for you.

Do you offer maintenance after launch?

Yes. We offer ongoing support for updates, security, backups, performance and SEO, so your website or app keeps working well after launch.

Do you work with clients remotely?

Yes. We work with clients by email and video call, and share progress on private staging links you can check at any time.
