FAIRNEX · Daegu, Korea

AI software for people who run the whole job alone.

FAIRNEX builds practical AI tools for one-person teams in Korea: the solo online seller and the solo general-affairs manager. Every product starts from work we have done ourselves.

Products

Three subscription products for two underserved roles. Each one replaces a stack of spreadsheets, outsourcing quotes and guesswork with a single tool.

NEXFIT

Live

For Coupang sellers

AI sourcing analysis and product detail page generation in one SaaS.

  • A Chrome extension collects competitors’ 28-day sales, reviews and shipping type.
  • Keyword scoring, competitor clustering and margin calculation feed a sourcing list.
  • A six-agent pipeline (analysis, research, copy, design, image, editing) builds a 24-section product page in under 10 minutes.
  • A canvas editor for final adjustments.
Web SaaS · monthly subscription

GA Workspace

Launching Oct 2026

For solo general-affairs managers

A Windows app that runs a company’s general-affairs work from one screen.

  • Contracts, payments and receipts; vendor settlements; inventory and supplies; vehicles, rentals and insurance.
  • A morning dashboard ranks today’s work: overdue payments, notice deadlines, missing receipts.
  • One-click one-page reports as PDF and as Excel with live formulas.
  • Local-first: business data and vendor bank details stay on the user’s PC and work offline.
Windows 10 · 11 desktop · monthly subscription

GA-ATLAS

Beta

For general-affairs teams

A knowledge map and AI assistant for every general-affairs task.

  • 162 tasks across 11 domains, each with procedures, checklists and templates.
  • AI answers cite the source manual. On legal and tax questions it explains what the answer depends on and where to confirm, instead of guessing.
  • Phone numbers and emails in questions are masked before sending; questions are not used for AI training.
  • Templates in DOCX, XLSX and Markdown (HWPX in beta), plus 11 fill-in document studios.

Built with Claude

Claude models from Anthropic run inside our products, and Claude Code is how we build them.

Claude Sonnet

Copy and judgment

In NEXFIT, Claude Sonnet writes the product-page sales copy and product names, and analyzes keywords and competitor clusters behind each sourcing decision.

Claude Haiku

High-volume tasks

Claude Haiku handles the frequent, fast steps: matching products to marketplace categories and reading text from product images.

Claude Code

How we ship

We build, test and maintain all three products with Claude Code, which lets a founder-led team ship and support them.

FAIR + NEXT

Our name combines a fair standard with the next step. That shows up in how the products behave.

01

Grounded, not guessed

NEXFIT starts from real competitor sales data. GA-ATLAS answers point to their source and say plainly when an expert must confirm.

02

Private by default

GA Workspace keeps company data on the user’s own PC. GA-ATLAS masks personal details and does not train on questions.

03

Built from the job

Our products come from eight years of hands-on general-affairs work and our own online selling since 2023.

Company

FAIRNEX began in 2023 as an online seller. Running a store alone showed how much time goes into finding products and making listings, which led to NEXFIT.

Our founder also spent eight years as a general-affairs manager, tracking rentals, vehicles, vendor contracts and supplies across ten separate spreadsheets. GA Workspace and GA-ATLAS are the tools that job always needed.
