Koala

Koala positions itself as an online classroom platform for teachers and their students, featuring a gamified, kid-friendly environment with a co-browser, interactive whiteboard, and invoicing built into the workflow. It emphasizes teacher controls, 3D avatars, and a marketplace for activities, backed by Y Combinator. The product aims to replace traditional Zoom-style classes with an all-in-one teaching space.

Koala Go provides a browser-based classroom with teacher controls over student permissions (drawing, interacting with the co-browser), a co-browser, whiteboard, 3D avatars, and interactive games within the browser. Teachers can upload PDFs and PowerPoints, link to external websites and tools (Wordwall, Raz Kids, Genially), and manage invoicing through Koala Go. The platform supports a marketplace for activities, supports invoicing in multiple currencies, and offers a marketplace revenue model with a Koala Go fee structure. Invoices can be sent even if not teaching, and Stripe Express accounts are integrated for payments and payouts. It is designed to handle worldwide invoicing and parental payments, with guidance and tutorials available for onboarding. Koala also runs weekly live demos and training sessions.

Who it’s for: K-12 teachers and tutors who run online classes and may monetize activities or tutoring sessions, particularly those seeking an all-in-one classroom with invoicing options and marketplace access.
