Why Selleo

Do you need to scale your EdTech platform?

Selleo is a senior full-stack team that helps you turn an EdTech platform into a fast-growing learning product—without building everything from scratch. We start with short discovery, cut scope to what users truly need, and set a clear delivery plan.

Then we ship core learning features like courses, quizzes, progress tracking, certificates, and admin tools, plus the essentials around them: payments, analytics, SSO, and integrations when needed. You get realistic estimates, weekly demos, and early risk flags - so the product stays stable while you add features. Full code ownership, no vendor lock-in.

How We Work

Built to match your goals, ready to scale with your product.

DESIGN THAT DRIVES BUSINESS

UI/UX That Drives Learner Engagement.

UX Research Process

An EdTech platform is only as good as its completion rates.

Our designers craft intuitive learning paths that reduce cognitive load, boost learner retention, and make complex educational content effortlessly engaging.

  • We start by exploring user needs, pain points, and market context through interviews, surveys, and analytics. This ensures every design decision is grounded in real insights.

  • Creating clear, low-fidelity screen layouts that map out the structure, navigation, and functionality before investing in visuals.

  • Interactive prototypes allow us to simulate real user flows, test ideas early, and refine based on feedback before development begins.

  • Delivering polished, visually engaging interfaces that match your brand and delight your users, while keeping usability at the core.

  • Observing how users interact with prototypes or finished designs to identify barriers and optimize for clarity, efficiency, and engagement.

  • We design inclusively, following WCAG guidelines to make products accessible to people with diverse abilities, ensuring no one is left out.

12 Best Training Platform for Employees in 2026 (+ When To Go Custom)

The best training platform for employees is the one people will actually use, your admins can manage without friction, and your budget can support over time.

How to Outsource App Development Without Blowing Your Budget

Outsourcing app development is not a rate-shopping exercise. It is a control decision. In the data behind this article, 33% of SMB app projects cost less than $10,000, while 32% go above $50,000, so there is no useful “average app development cost” to follow. The real budget win comes from better scoping, cleaner ownership, and […]

Struggling with LMS scalability in your EdTech product?

A scalable LMS is not the one with the biggest user count claim, but the one that maintains speed, stability, and administrative control as concurrency, integrations, and complexity grow. That matters because research cited in the brief shows only 9% of organizations are fully satisfied with their LMS, while the UCL cloud migration case improved […]
