# Kota Embed — Health insurance enrollment, embedded inside other companies' platforms.

> A multi-tenant .NET service behind an embedded enrollment flow: employers offer health insurance to their employees without leaving the software they already use, while the backend integrates with nine insurers across three regulatory regions.

## Overview

Kota Embed lets employers offer health insurance to their employees without leaving the software they already use — the enrollment flow runs embedded in a third-party platform, backed by a multi-tenant .NET service that integrates directly with insurers.

## Stack

- .NET
- PostgreSQL
- EF Core
- AWS
- OpenTelemetry
- Multi-tenant
- Webhooks

## Highlights

- Multi-tenant by construction: platform → employer → employee → group, isolated per tenant.
- Group setup, enrollment, quoting, amendment, renewal, policy import, and dependant management, each as its own workflow.
- Eligibility computed from provider rules rather than stored as a flag.
- Policy and plan data aggregated across insurers into a single response.
- A versioned public API and signed webhooks for the platforms doing the embedding.
- Insurer integrations over both HTTP APIs and scheduled SFTP file exchange.
