What Eslbase does

Eslbase is a UK-based private online TEFL (Teaching English as a Foreign Language) marketplace and content resource founded in 2005 by Keith Taylor, operating from Bristol, United Kingdom with 1-10 employees and serving users in more than 100 countries. The platform connects three customer groups: TEFL teachers and job seekers, language schools and employers recruiting teachers, and accredited TEFL/TESOL course providers. Its core product, Eslbase.com, combines a TEFL job board (free and premium listings at £50 per six-week cycle), a directory of 298 accredited training centers across 82 countries, a searchable CV database of teacher candidates monetized via CV credits, and a free teaching resource library covering worksheets, lesson plans, flashcards, and grammar reference content for English language teachers.

The technology stack is built on WordPress with Google Analytics for usage tracking, Google reCAPTCHA for spam protection, and PayPal, Stripe, Lemon Squeezy, and Paythen as payment gateways. Premium job listings integrate with Google for Jobs. There is no proprietary AI, no API exposure, and no disclosed mobile application; the product is a self-serve web platform without sales intervention. The affiliated sub-brand School of TEFL offers accredited TEFL courses and is cross-promoted on the Eslbase homepage with explicit affiliate disclosure.

Eslbase's business model is a hybrid marketplace plus content monetization structure. Revenue is generated from six streams: premium job adverts (£50 per six weeks), CV credit bundles (£15 to £110), premium language school listings (£98 per year), sponsored placements in the course and school directories, affiliate commissions on outbound clicks to course providers, and recruitment referral fees when candidates placed via Eslbase are hired. Pricing is publicly disclosed on the site, primarily pay-as-you-go with no required subscriptions, and the editorial/advertising disclosure policy maintains a separation between paid and free placements. The company has remained bootstrapped with no disclosed venture or private equity investment, and operates as a single owner-operator team under founder Keith Taylor.

Expansion highlights4 records

Direct peers

• TEFL.com: TEFL.com operates one of the largest TEFL job boards and TEFL course directories globally. It is the most directly comparable marketplace competitor, connecting teachers with jobs and accredited training courses in a similar dual-sided model.
• Dave's ESL Cafe: Dave's ESL Cafe is one of the oldest ESL/TEFL job boards and teacher forums. It competes for the same teacher and employer audience with job listings, discussion forums, and ESL teaching resources, making it a direct marketplace peer.
• TEFL.net: TEFL.net provides TEFL job listings, course reviews, and teaching resources aimed at prospective and current English teachers. It is comparable to Eslbase as a content-and-marketplace hybrid serving the same teacher job-seeker persona.
• ESL Job Feed: ESL Job Feed aggregates ESL/TEFL teaching jobs from across the web. It overlaps with Eslbase's job board functionality by serving teachers searching for international and online ESL positions.
• BusyTeacher: BusyTeacher is a large free resource library for ESL teachers offering worksheets, lesson plans, and printables. It competes with Eslbase's free teaching resources as a content destination for the same teacher audience.
• ISL Collective: ISL Collective is a major ESL worksheet and resource-sharing platform with a global teacher community. It overlaps with Eslbase's free resource library as a comparable content-driven destination for ESL teachers.

Broad incumbents

• TEFL Org: TEFL Org is a large, established TEFL training provider that also lists jobs and produces teacher resources. It overlaps with Eslbase in teacher resources and job listings but is primarily a course provider rather than a neutral marketplace.
• i-to-i TEFL: i-to-i is a long-running TEFL/TESOL course provider offering certifications, teaching resources, and job guidance. It competes with Eslbase's School of TEFL sub-brand and shares the same teacher-training content category.
• LinkedIn: LinkedIn is the dominant professional networking and jobs platform increasingly used for ESL/TEFL recruitment. As a broad incumbent with overwhelming employer adoption, it represents the most significant indirect competitive threat to Eslbase's job board.

Emerging players

• GoOverseas: GoOverseas is a marketplace for teach-abroad and work-abroad programs, including TEFL placements. It is comparable as an emerging marketplace intermediary in the international English-teaching hiring category.
