[ Overview ]

eBay isn’t just an e-commerce site, it’s a dynamic global marketplace where pricing, competition, and demand shift by the minute. Sellers relying on instinct fall behind. We built Indications, a full-scale intelligence system that tracks live trends, detects emerging competition, and reveals untapped opportunities, helping brands, power sellers, and investors act with data-driven precision.

The Challenge

Millions of listings. Constant price changes. No clear advantage.

For eBay sellers, staying competitive is tough. The platform evolves constantly - search rankings shift hourly, competitors tweak prices mid-day, and product listings vary wildly in format and quality. APIs offer limited access. eBay’s anti-bot systems block most external scrapers.

For power sellers and brands, the result was the same: opportunity blindness. They couldn’t track trends, monitor competitors, or optimise pricing - at least, not in real time.

Sellers needed a way to:

  • Track live search ranks, pricing, and stock

  • Understand competitor portfolios and sales velocity

  • Avoid being blocked or detected

  • Turn raw listing data into insights

That’s where Indications comes in.

Below is our brief value proposition video

Our Approach

We built Indications, a stealth-grade, high-scale eBay intelligence platform.

It does three things exceptionally well:

  1. Extracts market data at scale - listings, ranks, prices, stock, and sales

  2. Structures and cleans it - using AI to normalise messy attributes

  3. Delivers insights in real time - through dashboards, alerts, and reports

The platform was designed to stay invisible to detection systems, scale with demand, and offer sellers a crystal-clear view of their market - instantly.

What We Delivered

Stealth Scraping Infrastructure

  • Tiered scraping across search, product, and storefront views

  • Real-time tracking of ranks, pricing, and inventory

  • Automated crawling with session-aware IP rotation

  • Proxy blending, fingerprint spoofing, and anti-captcha

Smart Parsing & Normalisation

  • Attribute alignment across inconsistent listings

  • Detection of fast-moving SKUs and price changes

  • Cross-seller product mapping for apples-to-apples comparison

Seller Enablement Tools

  • Alerts for pricing shifts, rank drops, and competitor activity

  • SKU performance scoring and margin insights

  • Category trend detection and early-mover signals

  • Portfolio optimisation recommendations

User Experience That Works

  • Responsive, mobile-friendly dashboards

  • Clean UI designed in Figma

  • Embedded API access for advanced users

  • Seamless frontend in Webflow and React

Growth Strategy

We didn’t just build a tool - we scaled an ecosystem. To help Indications reach power sellers, we launched a multi-channel go-to-market strategy:

  • SEO content targeting seller search intent

  • Email campaigns powered by real eBay data

  • Ad retargeting tied to live demos

  • YouTube partnerships with eBay sellers and consultants

Tech Stack Overview

  • Backend: Python, Scrapy, PostgreSQL, Redis, Airflow

  • Anti-bot stack: ISP/residential proxies, spoofing, ML-based captcha solving

  • Frontend: React, Webflow, Figma

  • Growth: Google Ads, HubSpot, Email automation

The Impact

From Guesswork to Command.

Sellers using Indications report:

  • Double-digit ROI via smarter pricing and SKU strategy

  • Faster time-to-insight - from weeks to seconds

  • 90-day trend reports by product and seller

  • Real-time decision making - no more guesswork or lag

Indications helped eBay sellers do what they couldn't before:

  1. See the market clearly.

  2. React to it instantly.

  3. Win more often.

Building and Evaluating RAG Systems the Right Way

This article breaks down how RAG (Retrieval Augmented Generation) systems work and shows why most failures come from retrieval, ranking, or evaluation gaps rather than the model itself. It offers a clear framework that helps teams diagnose model drift, strengthen reliability, and scale enterprise-grade RAG systems.
