Fishtank Learning

What Fishtank Learning does

Fishtank Learning is a privately held, Boston-based (Jamaica Plain) educational curriculum provider serving K-12 teachers, schools, and districts in the United States. The company operates Fishtanklearning.org, a web-based curriculum platform delivering standards-aligned English Language Arts (Kindergarten through 12th Grade) and Mathematics (2nd Grade through Algebra 2) instructional materials under a freemium model. The platform is governed by Fishtank Learning, Inc., a Massachusetts-incorporated entity, and maintains FERPA compliance for student educational records. As of the latest data, the company employs 32 people and operates from headquarters at 769 Centre Street in Jamaica Plain, MA, with an additional office in Brighton, MA.

The core product architecture consists of three tiers. Fishtank OER is a free tier offering 200+ full units and 4,000+ daily lesson plans under a Creative Commons BY-NC-SA 4.0 license, with content-aligned assessments and a free account that does not expire. Fishtank Plus is a premium subscription adding Unit Launches (on-demand professional learning modules with videos, readings, and reflection prompts), enhanced lesson plans, editable Google Slides and handouts, assessment answer keys, and sample student responses. Fishtank Student is a purpose-built digital student-facing application that enables online assignments and assessments and is included with school site licenses. The ecosystem also includes a Teacher Tools library covering ELA and Math instructional strategies, a Professional Learning service for implementation support, and integration with Google OAuth, Google Drive for editable ELA slides, and Wistia for embedded video.

Fishtank monetizes through three revenue streams. Individual teacher subscriptions are priced at $129 per course annually with auto-renewal and credit-card-only purchase. School site licenses are priced at $12-$21 per student annually, depending on package, and include unlimited Fishtank Plus subscriptions for all teachers and staff plus an implementation support package, orientation, onboarding, and ongoing professional learning; purchase orders are accepted. The free OER tier serves as a customer acquisition funnel. Go-to-market is dual-track: self-serve for individual teachers via website registration, and a dedicated school partnerships team handling district-level sales with custom quotes. Distribution is direct through the website, with case studies demonstrating measurable student outcomes at urban and rural public schools across Massachusetts, New York, and Wisconsin. The company has no disclosed external funding and no parent or subsidiary structure.
