Ethical Web Designers Based in Leeds


The Main Cast


The driving force behind Sentiva and the one who oversees operations and keeps us all organised, Kat is equally suited to creative ideas and tactical business thinking, and loves simplicity and efficiency, so she always gets straight to the point and makes things as clear and straightforward as possible.


Iwona heads up the website department, consulting with new clients and supporting them as their website goes from strength to strength. She brightens up the office with her sunny, smiley disposition and is always happy to go the extra mile. Friendly and patient, Iwona will be your first point of contact and will support you as we work together to create your perfect product.


Tim is the team’s data guru, the analytical technical guy who can see the big picture as well as all the little cogs. He manages our software development projects and the transfer of data between systems. A whizz at imaginative problem-solving, he always seems to know all the answers (but in a supportive and helpful way!) His one weakness is his love of a good pun...


The strong, silent type, Chris is a self-confessed pedant, but when it comes to the technical side of things he’s also the man who makes it all happen. Analytical, methodical and a great chess player, Chris is a focused perfectionist who won’t stop until he’s 100% happy with the product he’s working on.


Slightly hairier than the rest of the team, Caleb shows less aptitude for web design but considerably more interest in a bowl of Pedigree Chum. With noble good looks, he barks a good bark, but in reality Caleb wouldn’t say boo to a goose.


Our ethos

In short, we care. We care about giving great customer service, about the quality of our work and about doing our bit for society and for the environment.

Ethical behaviour is important to us, so you can trust that we’ll always be honest about what we can do for you and what it will cost.

Our size allows us to be professional but responsive, and when you need to contact us you’ll always be talking to either Iwona or Kat. 

Happy to help

We want to be a positive force within our local community, so we do what we can to help charitable causes. If you’re a non-profit organisation, we’ll offer you a 20% discount on our prices.

And if you’re a local community group that could really benefit from a simple website but doesn’t have the budget for it, we’d love you to get in touch and have a chat with us – we might be able to create one for you free of charge.
