We believe teachers are the most overworked, underpaid professionals on earth. We built TeachShield to give you your evenings back.
Charles's sister is a teacher. We watched her spend weekends buried in grading, lesson plans, and admin work. Thirty essays on a Sunday night. Progress reports due Monday. No time left for the parts of the job that actually matter.
So we built TeachShield. Not another corporate EdTech tool that promises the moon and hands over a complicated dashboard. A straightforward platform that handles the repetitive work: grading, lesson planning, worksheet generation, classroom games. So teachers can focus on the part that matters. Teaching.
TeachShield is a product of Obsidian Clad Labs LLC, a husband-and-wife team in Tennessee. We believe software should solve real problems for real people. Simple. Affordable. On your side.
