Who are we?

At Byld, we don’t just build businesses—we create impactful ventures in collaboration with top-tier corporations. Since 2017, we’ve been designing, validating, and launching companies that merge the best of entrepreneurial agility and corporate muscle to scale innovative, sustainable solutions.

Our newest venture, Nesty, was born to simplify parenthood and promote conscious consumption. Through a flexible rental model, Nesty allows families to access premium baby gear without the hefty upfront investment—helping them save money, reduce waste, and embrace a more sustainable lifestyle.

Parenting is expensive, short-term needs change fast, and unused gear often clutters homes or ends up in landfills. Nesty challenges this model by offering convenience, flexibility, and circularity to today’s families—bringing them the freedom to rent what they need, when they need it.

Join us to redefine the parenting experience and lead the way in circular consumption!
