Beloga
Beloga was an AI-powered knowledge amplification platform co-founded in February 2024 by Wilson Ler and Jerica Kuah. Built on Retrieval-Augmented Generation (RAG) and Large Language Models, it was designed to help individuals and teams more effectively capture, connect, and develop collective insights — a more active approach to knowledge management than existing tools offered. The platform launched as 2nd Product of the Day on Product Hunt and ran through January 2025.
Problem and Thesis
Knowledge management software has historically treated knowledge as a filing problem: put notes in folders, tag them with keywords, search when needed. Tools like Notion, Confluence, and Obsidian all operate in roughly this paradigm. What Beloga set out to do differently was treat knowledge as something that grows through connection — where the value isn't in any single note or document but in the relationships between ideas, and in a system that helps those relationships emerge actively rather than waiting to be manually mapped 1.
The company's name and its tagline "knowledge amplification" pointed at an ambition beyond note-taking: not just storing knowledge, but making people smarter through the way the system surfaces and connects what they know.
Technical Foundation
Wilson Ler led technical architecture and product development from zero to one. The stack was built around RAG — a technique that grounds LLM outputs in retrieved documents, preventing hallucination and keeping responses grounded in the user's actual knowledge base — alongside modern LLM APIs and a Next.js frontend 2.
The choice of RAG as a core technology was deliberate and well-suited to the use case: in knowledge management, users care deeply about accuracy and attribution. Generic LLM outputs that confabulate or blend sources are worse than useless for someone trying to build on their own prior thinking. RAG allowed Beloga to act as a genuine amplifier of what the user actually knew, not just a fluent generator of plausible-sounding text.
Launch and Reception
The founders built the MVP in six months and launched publicly. At launch, Beloga earned 2nd Product of the Day on Product Hunt — a significant signal for a self-funded, first-time product launch 2. Product Hunt's ranking reflects a combination of upvotes, comments, and community engagement on launch day, making a top-five finish competitive in a field of hundreds of daily launches.
Constructor's CEO, Eli Finkelshteyn — Wilson's former employer — publicly endorsed the launch, calling Wilson "one of the best engineers we had" and recommending Beloga to his network 3.
Building Between Ecosystems
In an October 2024 podcast appearance, Wilson and Jerica discussed the experience of building Beloga between Canada and Singapore — comparing those ecosystems to the US and Europe, and reflecting on what it meant to build an AI startup without a direct Bay Area footprint 1. The conversation touched on the product's thesis about the future of knowledge management and the structural challenges of shipping a consumer AI product in a market increasingly crowded with well-funded competitors.
Shutdown
Beloga ran through January 2025. Wilson's LinkedIn notes the company under a "Co-Founder" role from February 2024 to January 2025 — suggesting a clean wind-down after roughly 11 months of operation 2. Both founders moved on to new projects: Wilson returned to Constructor and joined the ODF23 fellowship cohort, while Jerica continued building with Musey.me and Nomit.dev.
Context: The Knowledge Management Wave
Beloga was one of many AI-native knowledge tools that emerged in the 2023–2025 wave of RAG-based productivity software. The broader category included products like Notion AI, Mem, Rewind, and numerous others, all competing to become the primary interface layer between a person's knowledge and LLM capability. The market proved to be intensely competitive and difficult to monetize at the consumer tier, with many similar products either shutting down or pivoting to enterprise by mid-2025.
