Nick and Lily first met as students at Oxford. In 2023, they left their jobs to build Jack Fertility together.
Nick is a former diplomat turned consumer marketer, with experience across cigarettes, alcohol, coffee and fast food. All the really good-for-you stuff. Now he’s putting that same consumer obsession into something his mum can actually be proud of.
Connect with NickLily is originally from the USA, with a career spanning public health, law, banking and AI drug discovery. She brings the scientific, operational and strategic discipline that turns Jack from a good idea into something that actually works.
Connect with LilyJack’s core values were developed with the Oxford Character Project at the University of Oxford.
There will be a better way to test, a way to help people improve their health & create a family
Everyone with sperm deserves control over their fertility data
Messy problems need fresh thinking. Taboos need smashing.
Elegant and clear solutions to make everything as easy as possible
Less isn't a compromise when it's a design choice.
Samples and health data handled with absolute care and discretion
Nick, Jack’s co-founder, is a dad of two. He knows first-hand what it feels like to wonder about fertility, and how quickly men can be left out of the conversation.
Jack was built to change that: clear, trusted sperm health information, made easier to access, easier to understand and easier to act on.
Jack is a proudly British innovation, designed, developed and tested in-house at the Wood Centre for Innovation.
We built SpermShield™ from scratch because nothing on the market did what postal sperm testing needed. We designed the collection system around real life, not a clinic. From the test tube to the packaging, every detail has been built for accuracy, discretion and ease.
We spent over two years in R&D because we refused to compromise. Our preservative. Our lab. Our analysis. Our dashboard. We control the whole chain because that is how we protect the result.
If the experience puts someone off before they even open the kit, the science never gets a chance to matter.
