We’ve seen it happen too many times. You’ve invested in a new app or website for your business. The team are excited and everyone’s ready to launch. Then six months in, your budget has been blown, key features don’t work the way users need them to, and the project that was supposed to transform your business is now back at square one.

It happens too often, and we’ve been doing some thinking about why. Have a read. 🔗 Link in bio.

February Wrapped 📸

Another busy month here at Si HQ. Here’s a quick look back at what February had in store for us.

In 2019, we launched something that designers really connected with ✨

A set of 10 usability heuristic posters, free to download, print, and hang up in your workspace. Five years later, we’re still getting messages asking about them.

So we’ve given them a fresh look 🎨

These posters bring Jakob Nielsen’s usability principles to life, covering everything from system visibility to error prevention. Perfect for your studio wall or as a daily reference.

We’re back in the swing of things after Christmas and New Year. Check out what we’ve been up to this month 🎞️

📞 We woke up in the 00’s today. We’ve been tidying up the office the last couple of weeks and found a few retro devices in the cupboards. A total throwback for a lot of us. We used to test on these devices back in the day! What was your favourite retro phone brand?

Conference day ✨

We were at Shaping Portsmouth 2026 on Friday, listening to some genuinely inspiring people talk about the future of our city. Plus, Steve got his moment in the spotlight 🎤

Fresh Pantone guides just landed on the desk 🎨

There’s something satisfying about cracking open fresh colour swatches for a brand project. These new guides are helping us lock down the perfect palette for a client who’s going through a complete rebrand.

The best part of a brand job? Getting to build brands from the ground up.

December Wrap-Up 📸

It’s nearly Christmas, and as we shut down for the festivities, we thought we’d share some of our favourite moments from 2025.

Have a merry Christmas and a happy New Year! See you all in 2026 🎉

The office is all dressed up for Christmas and we’re feeling the festive vibes already! Who else has their decorations up? 🎅🏼🎁

November Wrap-Up 📸

It’s been a busy one with projects kicking off, conferences, and so much more…

14/11/2025

⏱️ We had a great day Agency Hackers Clockwork conference at the British Library. It’s always good to get some time away from the office (and learn some new things along the way).

Already looking forward to next year 👀
