SaaS web design
A SaaS web design agency for B2B teams who need the site to sell
We design and build marketing sites for B2B SaaS companies. Clear positioning, pages drawn from your real product, and a CMS your team can run without waiting on a developer.

Sound familiar?
Signs your website is holding the business back
Most SaaS teams come to us with at least two of these. None of them get fixed by a new colour palette.
-
Every change needs a developer
A new landing page or a pricing tweak sits in the engineering queue for weeks.
-
The site looks smaller than the product
Buyers see a template, then a great demo. The site should do the product justice.
-
Nobody can say what you do in one line
The homepage lists features instead of the problem you solve and who it's for.
-
It's slow on a phone
Heavy scripts and huge images push people away before the page even loads.
-
It barely shows up in search
No structure, no metadata, and nothing AI assistants can quote back to buyers.
-
You can't tell what's working
Traffic comes in, demos don't, and there's no data on where people drop off.
GTM intelligenceKeyplay's team now ships pages without engineering
- What they needed
- Their site was static and hard-coded, so every content update waited on engineering.
- What we did
- Rebuilt the site on a modular block design system with a CMS, so the marketing team builds new pages from ready-made sections.
- What changed
- Keyplay launches pages and campaigns on demand, and we keep shipping improvements as their go-to-market changes.
Siguro are a rare service provider that understands startup life and can deliver at your pace.

Everything a B2B SaaS website needs, from one team
Strategy, design and code in one place. What you approve in design is exactly what goes live.
-
Positioning and messaging
We start with who you sell to and why they switch, then write the page structure around it.
-
UX and page structure
Homepage, product, pricing, demo and use case pages, each built to move a buyer one step closer.
-
Design drawn from your product
Real UI, clean product shots and a system that makes every new page look on brand.
-
Built on Astro
Fast static pages, no plugin sprawl, and code any developer (or AI agent) can pick up.
-
A CMS your team can run
Edit copy, add pages and launch campaigns yourself. Every change is saved to git.
-
Fast and ready for search
WebP images, structured data, clean sitemaps and redirects handled at launch.
Siguro's speed and technical expertise blew us away. They built our website from scratch in no time, and they were super responsive throughout the process.
Melanie MillsFounder / CEOHow it works
How a SaaS website project runs with us
The homepage comes first. Once its style is right, every other page follows fast.
- 01
Kick-off call
We learn who you sell to, what's not working and what the site needs to do.
Week 1
- 02
Homepage first
We design the homepage until the style and message feel right, and you sign it off.
Weeks 1 to 2

Roll out the rest
Product, pricing and use case pages follow the same system, so they move quickly.
Weeks 2 to 4

Product adoptionChameleon's new brand, live in time for their $13M Series A
- What they needed
- A brand refresh rolling out across the website, paid ads and illustrations, all consistent before the Series A announcement.
- What we did
- Redesigned key pages and ad creatives around the new brand, then A/B tested variations using Hotjar session replays and Mixpanel funnel data.
- What changed
- A consistent brand across every touchpoint at launch, and a demo page rebuilt to answer the questions prospects had before booking.
They move super quickly and we're able to be very lean, test and iterate effectively.

Chameleon's Series A, announced on the site we redesigned
Chameleon case study
Arvow went from hardcoded pages to a site the team can grow
- What they needed
- Their site was a static Next.js build, hardcoded and hard to manage as the product matured and rebranded.
- What we did
- Restructured the site, designed a new modular system for the rebrand, and moved every page onto a CMS.
- What changed
- The team makes updates without code, and the site finally matches the polish of the product.
Part of building a brand is taste in design, which influences the brand's perceived value a lot. Jamie's designs did that for us. We don't look like a cheap brand, we look trustworthy and worthy of a scroll.

Questions about SaaS web design
What does a SaaS web design agency actually do?
We plan, write the structure for, design and build your marketing site. For SaaS that means explaining a product people can't touch yet, showing the real UI, and making pricing, demo and trial pages easy to act on.
What do you build SaaS websites on?
Astro, with our own CMS on top. Pages are static and fast, the code lives in your git repo, and your team edits content without touching code.
Can our marketing team edit the site without a developer?
Yes. Every page is built from reusable sections, so your team can change copy, add pages and launch campaigns themselves.
Will a redesign hurt our SEO?
Not if it's done properly. We keep the URLs that rank, set up 301 redirects for anything that moves, and ship a clean sitemap and structured data at launch.
Do you work with early-stage startups?
Yes. Most of our clients are venture-backed B2B SaaS teams, from early startups to companies announcing a Series A.
How does pricing work?
We work on a monthly plan rather than a fixed-scope project, so you can keep shipping after launch. See our plans for the details.
