Founded by Christina Castelli — a former senior editor at two major educational publishers who spent years managing content vendors from the publisher side, and built Inksplash after deciding there had to be a better way.

That origin shapes our unique approach to projects: We plan extensively before building, every project manager has genuine content expertise, and we raise problems proactively—not after delivery.

Every client who has worked with Inksplash has come back. That’s not an accident.

Does your current vendor make you feel like you’re managing them rather than having a true partner? We were built to solve that.
