We would like to congratulate Beth Bishop on her wedding over the weekend.

From all of us at Castus, we are wishing you both a lifetime of happiness, laughter and love.

…. And yes this is the only photo we managed to get of some of the Castus team 😅

Our team day out in the Peak District yesterday.

We made it to the top of Mam Tor... and couldn't see a thing thanks to the fog!

Typical that as soon as we got back down, it cleared and the blue skies came out 😂

Still, it was a great day out, plenty of laughs and a nice chance to catch up away from the office. Here's a few photos from the day.

A rare week where the whole team is in the office!

With Tomas and Mark flying in for the week, our daily stand-up is finally an actual stand-up instead of everyone asking, "Can you hear me?" 😂

We’re proud to sponsor Josh Layton and support a local athlete putting in the work every single day. 🥊

The dedication and discipline shown day in and day out is exactly what we admire.

We're excited to follow the journey and see what’s ahead.

The Hidden Knowledge Gap Between Your Business and Your Development Agency | Castus Custom Software 22/04/2026

Are you unknowingly losing value from your development projects due to a hidden gap between your business and your agency?

This “knowledge gap” can lead to misaligned expectations, unclear communication, and ultimately, projects that don’t deliver the full value they should. In many cases, it’s not a lack of expertise, it’s a disconnect in understanding, priorities, and how technical work translates into real business outcomes.

We’ve written a short blog exploring where this gap comes from, the signs to look out for, and how to bridge it to get better results from your digital projects.
