How it works

From brief to delivery

A simple, transparent flow built around your guidelines and your quality bar.

Brief

You share goals, languages or dialects, volume and guidelines under NDA.

Recruit & test

We source native Bangla talent and run a screening task built from your rubric.

Pilot batch

A small paid batch to calibrate quality, speed and guideline understanding.

Scale with QA

Reviewers audit samples, flag drift and retrain the team as guidelines change.

Report

Agreement rates, issue notes and delivery summaries, on a schedule you choose.

Iterate

Feedback loops to refine rubrics and keep quality steady over time.

Our working principles

  • NDA first, project-scoped access, no sharing of client material
  • Evaluators are never charged to join
  • Quality over speed, and honest reporting when something is off

About

Careful judgment, clearly explained

Pesible was started by Abdur Rahim Hossain, an AI model evaluator based in Narayanganj. After four months of speech and multimodal evaluation work, he saw how much Bangla needs native human review and set out to build a team that can provide it.
