# Eloster

*/Startups/Eloster*

## Startup Overview

This schema management system automatically propagates data structure changes across decoupled event streams. Data engineering teams use the platform to prevent breaking changes when upstream data formats evolve.

Distributed architectures rely on continuous event streaming, but altering a single payload structure often breaks downstream consumers. Engineers typically rely on manual coordination or hardcoded downstream migrations to keep systems aligned. This friction delays deployments and increases the risk of data loss or pipeline failures.

Unlike Confluent Schema Registry or Snowplow, the architecture makes data contracts version-controlled by default and integrates them directly into existing CI/CD pipelines. When a developer commits a schema alteration, the platform automatically validates the change and updates downstream configurations before code reaches production. This guarantees strict compatibility across the event mesh without requiring manual intervention.

## Startup Founding Hypothesis

## Startup Offer

**Proof**:
- Aiming to eliminate unhandled downstream pipeline breakages for enterprise data engineering teams.
- Targeting a reduction in manual schema migration tasks from weeks to automated CI/CD approvals.
- Designed to perform schema validation via edge-cached resolution with a target of sub-5ms latency.
**Tiers**:
- Name: Developer Stream · Price: ~$0–$50/mo · Inclusions: Up to 10 active schema definitions and 100 million validation events per month, designed for staging and local development.
- Name: Production Propagator · Price: ~$500–$1,200/mo + ~$0.05 per 1M events · Inclusions: Unlimited schema definitions, automated CI/CD gating checks, and designed to generate pull requests for up to 50 downstream consumer repositories.
- Name: Enterprise Fleet · Price: enterprise: ~$4,000–$10,000/mo · Inclusions: Dedicated single-tenant infrastructure, custom downstream webhook propagation, and intended compatibility with high-throughput Apache Kafka architectures.
**Guarantee**: If an unhandled schema evolution merges into production without triggering a blocked CI build or a generated downstream pull request, Eloster refunds the month's platform usage.
**Business Function**: ProvideService
**Objection Handlers**:
- We already use Confluent Schema Registry for this. -> Confluent stores schema state; Eloster natively gates breaking commits in your CI/CD pipeline and actively propagates the updates.
- Downstream consumers need control over when they adopt new schemas. -> Eloster is designed to open automated pull requests to downstream repositories, allowing them to review and merge at their own pace.
- Inline validation will bottleneck our high-volume event streams. -> The platform relies on asynchronously updated, edge-cached local validators intended to prevent network round-trips during runtime.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- 14-day staging pilot: Implement Eloster's CI/CD gating on a single core schema to prove the platform successfully intercepts and blocks simulated breaking commits before they merge.
- 30-day downstream propagation pilot: Configure Eloster across one producer and three consumer repositories to validate that automated pull requests generate correctly and allow consumers to adopt schema changes at their own pace.
**Target Metrics**:
- Target: 0 unhandled downstream pipeline breakages caused by schema evolution
- Aim: Reduction in manual schema migration task duration from an average of 2 weeks to under 1 hour
- Target: Sub-5ms runtime schema validation latency via edge-cached resolution
- Aim: 100% automated pull request generation for up to 50 downstream consumer repositories per schema update
**Target Case Studies**:
- Target: A mid-market SaaS data engineering team transitions from coordinating manual Jira tickets for schema updates to using automated downstream PR generation, eliminating unhandled data pipeline outages.
- Target: An enterprise fintech infrastructure team integrates Eloster into their high-throughput Apache Kafka architecture, utilizing CI/CD gating to block 100% of breaking schema changes before production deployment.
- Target: A high-growth consumer application startup implements edge-cached validators, successfully processing over 100 million monthly validation events while maintaining sub-5ms latency and zero network bottlenecks.
**Testimonial Targets**:
- Lead Data Engineer: Expresses relief that breaking schema commits are caught and blocked natively in the CI/CD pipeline instead of triggering midnight production incident alerts.
- Downstream Application Developer: Shares appreciation for receiving automated, reviewable pull requests for schema adoption, giving their team control over when they adopt new schemas.
- VP of Cloud Infrastructure: Validates that the edge-cached local validators maintain high-volume event stream throughput without adding network round-trip bottlenecks.

## Startup Story Brand

**Hero**:
- **Need**: to be the architect of a resilient data mesh, not a firefighter patching broken consumers
- **Want**: to propagate schema changes across decoupled streams without breaking downstream pipelines
- **Identity**: the lead data engineer at an event-driven enterprise
**Plan**:
- Step: Define · Detail: Commit your updated schema definition directly to your version-controlled repository.
- Step: Inspect · Detail: Review the automated CI/CD gating check that validates your change against all registered downstream consumers.
- Step: Propagate · Detail: Approve the generated pull requests sent to downstream repos to synchronize the entire fleet.
**Guide**:
- **Empathy**: When a breaking change merges into a producer stream, downstream data pipelines crash before you even receive the Slack alert.
**Problem**:
- **Villain**: schema drift
- **External**: Updating a central event definition in Confluent Schema Registry often causes silent failures in downstream Python, Go, and Java consumers.
- **Internal**: You feel like you are walking through a minefield every time you merge a pull request to the event-producer repository.
- **Philosophical**: System-wide structural integrity belongs in the deployment pipeline, not in reactive manual migration tickets.
**Success**: Schema evolutions flow from producers to consumers automatically, ensuring every pipeline stays green while your event-driven architecture scales.
**One Liner**: Schema drift costs data teams weeks of manual migration debt. Eloster automates schema propagation so downstream pipelines never break on a merge.
