Our Values & Culture

we’ve built a client-focused culture around our five key values

1. Integrity

We’ll always be honest with you and with ourselves, even if that sometimes means sharing bad news.

2. Discipline

Great code requires rock-solid discipline. Our work will always be to the best of our ability.

3. Adaptability

No situation is the same. We adapt our processes and techniques to optimise our service to you.

4. Responsiveness

We respond quickly to messages and changes so no one has to sit idle when there is work to do.

5. Accountability

We take our commitments seriously and keep our promises. If we ever make a mistake, we fess up quickly and clearly.

Our Story

App Sapiens was founded in 2019 by longtime collaborators and best friends Tom Riglar and Charles Killer.

Tom has a background in leading solution design and implementation. He's worked with enterprise clients such as Vodafone, the BBC and Channel 4 and consulted for pioneering startups including Cutover and Ownable.

Charles' history is as a principle developer and software architect. He's contributed code to Expo's core and to the Arctic Code Vault. His previous client roster includes Mitie, Disney and the Discovery Channel.

Tom & Charles built a vision around a core modern principle:

Pioneering businesses use innovative apps to outpace their competition.

Today, our expert-led, fast-growing company has helped dozens of clients transform their vision into high-value digital products and market-beating software strategies.

Perhaps we can help yours too?
