A web application for an ad-tech company that connects brands with opinion leaders, analyzes influencers' followers for authenticity, and runs influencer campaigns with full automation.

## Case study facts

- **Client:** Startell
- **Industry:** Startups
- **Project type:** Web application
- **Services:** Software Product Engineering, Web & Mobile App Development, API Development

## What NPCoding delivered

- Matches companies with relevant influencers and opinion leaders
- Analyzes influencers' followers, including authenticity checks
- Runs influencer campaigns with full, precise automation

## The client

Startell is a company with technological capabilities in advertising. Its influencer system connects companies with opinion leaders to create leading campaigns in every field. Startell operates in Israel and abroad and has raised funding from international investors.

## The brief

Influencer marketing has a trust problem: brands need to know whether an influencer's audience is real and relevant before spending money. Startell's product vision was a system that **finds the right influencers, verifies their audiences and runs campaigns automatically** — replacing a slow, manual process with software.

## What we built

We built the **web application for managing influencer campaigns**.

### Matching brands with opinion leaders

The system connects each company with influencers suited to its campaign, turning a spreadsheet-and-DM process into a structured workflow.

### Audience analysis and authenticity checks

For every influencer, the platform performs **precise analyses** — including **checking the authenticity of their followers** and **analyzing who those followers are** — so brands invest in genuine reach.

### Campaign automation

Once the match is made, companies can run influencer campaigns with **full and precise automation**, from launch to tracking.

## How we worked

Product-engineering projects like this one hinge on a few early decisions: which data sources power the analysis, how results are presented to non-technical marketers, and which steps are safe to automate. Getting those right is what turns an idea into a platform people trust.

## The outcome

Startell operates a platform that lets brands in Israel and abroad find, vet and activate influencers with automation instead of guesswork. We also built the site for [OverCat](https://npcoding.ca/portfolio/overcat/), a PR company based in Canada, including a password-protected media hub for suppliers.
