# Echodeck

*/Startups/Echodeck*

## Startup Overview

This system captures live, stateful production API traffic and replays it on demand for development and testing environments. Engineering teams deploy it as a drop-in layer that observes actual requests and responses, recording the exact sequence of data mutations in real time. Instead of relying on static fixtures, developers run tests against identical copies of complex production workloads.

Software teams face massive friction when testing distributed applications because manual staging clusters are expensive to maintain and quickly drift from production reality. Traditional tools like WireMock or Postman Mock Servers require developers to manually write and update static response definitions, which fail to accurately mimic dynamic, sequential data changes. This leaves engineers guessing whether local code modifications will break multi-step workflows.

By remaining entirely state-aware upon replay, the architecture accurately simulates deep API interactions where subsequent requests depend on prior data states. The environment provisions with completely zero configuration, eliminating the need to author mock scripts or stand up staging databases. Developers instantly generate isolated replicas of production conditions, execute integration tests, and destroy the instances without touching underlying infrastructure.

## Startup Offer

**Proof**:
- Targeting 99.9% state-accuracy during complex multi-step API transaction replays
- Aiming to eliminate the need for manual staging cluster maintenance for microservice developers
- Intended to reduce stateful integration testing setup from days to completely zero-config
**Tiers**:
- Name: Team · Price: ~$150–$300/mo · Inclusions: Up to 25 million recorded production API requests per month, 7-day state retention, and baseline automated redaction rules for small engineering teams.
- Name: Platform · Price: ~$700–$1,500/mo · Inclusions: Up to 150 million recorded requests per month, 30-day state retention, cross-service transaction tracking, and advanced payload masking for platform engineering units.
- Name: Enterprise Grid · Price: ~$3,000–$8,000/mo · Inclusions: Unlimited traffic capture nodes, 1-year state retention, intended SAML/SSO integration, and designed for VPC-peered dedicated deployments.
**Guarantee**: If the replay engine fails to accurately recreate the exact sequential state of your captured API traffic during local testing, your team receives a full refund for that month of service.
**Business Function**: ProvideService
**Objection Handlers**:
- Security of PII in production payloads: Echodeck is designed to apply customizable payload masking and redaction rules before any captured traffic leaves your environment.
- Latency impact on live production services: The capture agents are built to process traffic asynchronously, targeting less than 2ms of overhead per request.
- Inability to handle downstream database mutations: Echodeck does not mock the database; it replays the exact sequential network calls to natively recreate the downstream state.
- Integration with existing CI/CD pipelines: The platform is intended to expose a headless API designed to trigger replays directly from standard GitHub Actions or GitLab pipelines.

## Startup Buyer Chain

**Chain**: Echodeck → Platform Engineering → Software Developers
**Gtm Motion**: Acquires users through bottom-up developer adoption when engineers seek zero-config local testing tools to unblock feature work. Expands revenue by converting individual users into team-wide deployments when platform engineering mandates the tool to decommission manual staging clusters.
**Agent Channel**: Designed to list in the Model Context Protocol (MCP) registry, allowing autonomous coding agents to discover the capability and provision stateful test environments during automated QA tasks.
**Primary Channel**: Technical search intent for 'stateful API mock server' and discovery via open-source repositories and developer-focused aggregators like Hacker News.

## Startup Proof Points

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

**Pilot Goals**:
- A 14-day local testing pilot with a microservices team aiming to capture 25 million production requests and replay them with zero state-accuracy errors.
- A 30-day CI/CD integration pilot with a platform engineering unit to prove headless replay execution directly from GitLab pipelines via the Echodeck API.
- A 60-day enterprise trial to validate customizable payload masking rules and 1-year state retention across VPC-peered dedicated deployments.
**Target Metrics**:
- Target: 99.9% state-accuracy rate during complex multi-step API transaction replays
- Target: <2ms latency overhead per asynchronous capture request on live production services
- Target: 0 hours of manual staging cluster maintenance required per month
- Target: 100% reduction in database mocking setup via native sequential network call replays
**Target Case Studies**:
- Target: A mid-sized fintech platform engineering team eliminates the maintenance of fragile shared staging clusters by replaying masked production API traffic locally for testing.
- Target: A startup microservices development group reduces stateful integration testing setup from three days to zero-config using sequential network call captures.
- Target: An enterprise SaaS DevOps department integrates headless API replays into standard GitHub Actions while verifying sub-2ms production latency overhead.
**Testimonial Targets**:
- Platform Engineering Lead: Expresses relief at eliminating the team's reliance on shared staging databases by successfully using exact sequential network replays.
- Senior Microservices Developer: Highlights the immediate ability to instantly replay complex production traffic locally without configuring downstream database mutations.
- Chief Information Security Officer: Confirms confidence in the local capture agents that apply masking and redact PII before payloads leave the environment.

## Startup Top Risks

- Severity: existential · Description: Production traffic capture inadvertently stores and exposes sensitive PII triggering immediate enterprise compliance failures. · Mitigation Status: unmitigated
- Severity: high · Description: Zero-config stateful replay fails to accurately simulate complex multi-database transactions forcing users back to manual staging clusters. · Mitigation Status: in-progress
- Severity: moderate · Description: Traffic capture introduces unacceptable latency overhead on the host application production API endpoints. · Mitigation Status: in-progress
- Severity: low · Description: Engineering teams default to extending existing Postman setups with internal scripts rather than adopting a new standalone testing tool. · Mitigation Status: unmitigated

## Startup Story Brand

**Hero**:
- **Need**: to lead a team that ships code with verifiable certainty instead of guesswork
- **Want**: to debug production-level failures without maintaining brittle staging environments
- **Identity**: a microservices lead at a high-growth platform engineering unit
**Plan**:
- Step: Capture Traffic · Detail: Deploy the asynchronous agent to record real production API flows with under 2ms of overhead.
- Step: Confirm State · Detail: Verify the captured sequence matches the multi-step transactions you need to replicate locally.
- Step: Replay Locally · Detail: Run the exact production traffic against your local dev environment to squash bugs instantly.
**Guide**:
- **Empathy**: Deployment windows are won in the local environment — but production-grade state is usually lost in the gap between services.
**Problem**:
- **Villain**: The Staging Cluster
- **External**: Maintaining manual staging clusters for microservices takes days of drift-fighting across Postman and Kubernetes while failing to catch stateful race conditions.
- **Internal**: You feel like a glorified environment janitor instead of an engineer, constantly fixing broken mocks that don't match reality.
- **Philosophical**: Engineering talent belongs in product architecture, not in the mimicry of production environments.
**Success**: You debug production failures on your local machine with zero-config replay, eliminating the need for staging maintenance forever.
**One Liner**: Every deployment, microservice developers struggle with broken mocks. Echodeck captures and replays stateful production API traffic so teams debug locally with 100% accuracy.
**Positioning**:
- **So That**: debug production failures locally without maintaining any staging environments
