What we do
Toy Design
Concept through production-ready design, from first sketch to factory hand-off.
Pitch Pages
Sell sheets and sizzle materials built to get a concept greenlit in the room.
3D Prototypes
Printed, finished models that let buyers hold the idea instead of imagining it.
Inventor Relations
Submission strategy, licensing guidance, and navigating the toy company pipeline.
Who we are
Secret Level Toys is a boutique toy design studio built on one idea: great toys come from people who have actually shipped them. We work as a design partner to toy companies and as an invention house pitching original concepts — and the two feed each other.
Our founder
Harrie Sivanander has spent 20 years in the toy industry, with product credits including Bitzee, Hatchimals, Tech Deck, and Primal Hatch, and over $500 million in retail sales across his career. He founded Secret Level Toys to bring that experience to independent inventors and companies who need senior design thinking without a senior headcount.
Our network
Behind the studio is a curated global network of designers, sculptors, CAD developers, model makers, and engineers, assembled per project. You get the right specialist for the job rather than whoever happens to be on staff.
