Company profile

researched Sep 2026

Lingco Language Labs, Inc. is a Delaware-incorporated company based in Lansing, Michigan, that operates a cloud-hosted software platform for language education in schools. The platform combines a library of pre-built content and activities with course-building tools, allowing instructors to assemble and adapt courses rather than sourcing materials themselves, and to track learner progress across the learning journey.

The company positions its technology as adaptive: courses adjust to an individual student's level and learning style, and analytics are used to surface potential learning gaps and content recommendations that help teachers direct classroom progress. Its stated approach also emphasizes cultural immersion content and an "I can" method of working with vocabulary and the relationships between learned items to improve retention. Because the software processes student education records, the company operates as a "school official" with legitimate educational interests under FERPA and commits to using student information only to fulfill its customer agreements.

Founding story

Co-founder and CEO Seth Killian studied computer science with a French minor and had taken three years of high school French without gaining speaking ability. A study-abroad term in Paris, where courses were taught exclusively in French, moved him from beginner to advanced and shifted his view of language learning. Observing that existing language apps neglected learner proficiency level and cultural immersion, and drawing on his software background with personalization algorithms, he set out to apply a comparable adaptive approach to language classrooms.

Business model

Lingco sells access to its hosted software to educational customers under subscription orders. Its terms of service set out per-term subscription fees invoiced to customers, with payment due within 45 days of invoice receipt and no refunds.

Subscription fees paid per order term for access to the cloud-based Lingco platform.

Traction

Market position

Positions itself within school-based language education as an adaptive learning provider, contrasting its teacher-facing, classroom-integrated approach with consumer language learning apps that it says do not tailor instruction to learner level or emphasize cultural immersion.

Stated differentiators include adaptivity to individual students in a school setting, tools intended to reduce teacher workload and enable differentiated instruction, an "I can" approach to vocabulary and concept relationships for retention, and culturally focused content.

Technology

A cloud-hosted web and software platform accessed remotely. It applies adaptive technology and artificial intelligence to tailor courses to each student's level and learning style and to derive insights such as learning gaps and content recommendations for teachers. The company maintains a public GitHub organization with documentation (MDX) and a TypeScript editor repository.

Go-to-market

Direct sales to schools and districts, supported by pilots and demo requests through the company website. As of 2023 the company had validated the product in a handful of districts through pilots and sales and identified building a broader distribution strategy as its next milestone.

Foreign language teachers, world language programs and K-12 school districts; the company reports reaching some of the largest school districts in the United States.
