# Errorseal

*/Startups/Errorseal*

## Startup Overview

This system intercepts and halts malformed data payloads before they execute at the database layer. By operating directly in the execution path, it guarantees that only structurally sound, validated queries reach critical storage infrastructure. It acts as a rigid barrier against corrupt or unexpected inputs that cause application crashes and database pollution.

Database reliability and backend engineering teams deploy the engine to eliminate downtime caused by bad downstream requests. Rather than relying on fragile, in-house validation scripts, teams enforce strict, automated data contracts right at the database boundary. This removes the manual operational burden of rolling back corrupted tables and investigating payload-induced outages.

Unlike legacy API gateways that enforce rules at the network edge or reactive observability tools that only flag failures after the data is written, this approach is entirely inline-enforcing. It operates with zero latency in the execution path, catching and dropping malformed queries instantly. This shifts fault management away from post-incident triage and into strict, frictionless prevention.

## Startup Founding Hypothesis

**Approach**: that intercepts and halts malformed payloads before database execution
**Competitors**:

- [reactive observability tools](/Competitors/reactive_observability_tools)
- [in-house validation scripts](/Competitors/in-house_validation_scripts)
**Differentiator2x2**: inline-enforcing rather than post-incident, and zero-latency in the execution path

## Startup Offer

**Proof**:
- Targeting mid-market fintechs aiming to eliminate schema-mismatch database rollbacks.
- Aiming for sub-millisecond p99 latency overhead on critical path transactions.
- Designed to reduce incident-response engineering hours related to bad data payloads by up to 90%.
**Tiers**:
- Name: Developer · Price: Free up to ~50k requests/mo · Inclusions: Baseline schema validation rules, intended for local development and staging environments.
- Name: Production · Price: ~$0.10–$0.25 per 1,000 processed payloads · Inclusions: Unlimited staging and production environments, custom validation schema support, and real-time payload rejection alerts.
- Name: Enterprise · Price: ~$1,500–$4,000/mo minimum commitment · Inclusions: Volume discounting, intended dedicated VPC deployment, and sub-millisecond latency SLA guarantees.
**Guarantee**: If Errorseal fails to halt a malformed payload that explicitly violates your active strict schema, resulting in bad database writes, we will refund that month's usage fees.
**Business Function**: ProvideService
**Objection Handlers**:
- Won't this add latency to our core API? -> Errorseal is designed to run locally within your infrastructure, targeting negligible sub-millisecond execution overhead.
- We already use an API gateway. -> Gateways handle coarse-grained auth and rate-limiting; Errorseal performs deep schema inspection right before the database write.
- What if the validation service crashes? -> Errorseal is engineered with a configurable fail-open or fail-closed toggle, letting you prioritize uptime or strict data consistency during an outage.

## Startup Proof Points

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

**Pilot Goals**:
- Target: A 14-day shadow-mode deployment in a staging environment to successfully log and flag 100% of malformed payloads without interfering with the existing write path
- Target: A 30-day production pilot running in fail-open mode, aiming to validate the sub-millisecond p99 latency SLA on high-volume API requests
**Target Metrics**:
- Target: <1ms p99 latency overhead on critical path payload validations
- Target: 90% reduction in engineering hours spent remediating bad data writes
- Target: 0 database rollbacks caused by schema-mismatch errors in production
- Target: 100% halt rate for payloads explicitly violating active strict schemas
**Target Case Studies**:
- Target: A mid-market fintech processing high-volume ledger transactions, transforming their operation by eliminating database rollbacks caused by schema-mismatched payloads
- Target: A B2B SaaS platform handling webhooks from third-party integrations, using Errorseal to halt undocumented payload mutations before they corrupt downstream analytics tables
- Target: An enterprise healthcare data provider, demonstrating how deep schema inspection blocks non-compliant patient data entries without adding latency to the critical API path
**Testimonial Targets**:
- Target: A VP of Engineering praising how strict schema enforcement catches breaking API changes from third-party webhook providers before they corrupt the internal database
- Target: A Lead Database Administrator expressing relief that schema-mismatch incident response and manual rollback operations are entirely eliminated from their weekly workload
- Target: A FinTech Chief Technology Officer confirming that deep payload inspection runs with sub-millisecond latency and never disrupts critical payment transaction flows

## Startup Top Risks

**Risks**:
- Severity: existential · Description: False positive payload interceptions drop legitimate production database transactions, causing catastrophic downtime and immediate customer churn. · Mitigation Status: in-progress
- Severity: high · Description: The inline interception agent introduces unacceptable latency spikes under high-throughput traffic, violating the core performance guarantee. · Mitigation Status: unmitigated
- Severity: high · Description: Enterprise security teams veto the deployment because the tool requires decryption and inspection of sensitive database payloads in memory. · Mitigation Status: in-progress
- Severity: moderate · Description: Complex proprietary ORMs and non-standard data serialization formats bypass the interception rules engine. · Mitigation Status: in-progress

## Startup Story Brand

**Hero**:
- **Need**: to be the architect of an unbreakable system, not the firefighter fixing rollbacks
- **Want**: to prevent malformed payloads from corrupting production databases
- **Identity**: the backend engineering lead at a mid-market fintech
**Plan**:
- Step: Upload schema · Detail: Submit your OpenAPI or JSON Schema specifications to define your strict production requirements.
- Step: Check traffic · Detail: Verify that every inbound payload matches your rules before it ever touches your database driver.
- Step: Enforce integrity · Detail: Activate inline-rejection to automatically block invalid writes and receive real-time alerts.
**Guide**:
- **Empathy**: When a third-party webhook sends a string where your schema expects an integer, your engineering team loses hours to manual data cleanup.
**Problem**:
- **Villain**: schema-mismatch rollbacks
- **External**: Invalid JSON payloads bypass your legacy API gateway and trigger cascading database errors in PostgreSQL or MongoDB.
- **Internal**: You feel anxious every time a new partner integrates with your API, fearing a single bad field will crash your weekend.
- **Philosophical**: API infrastructure was built for connectivity, not for becoming a dumping ground for malformed data.
**Success**: Your database remains pristine with zero-latency enforcement, blocking every malformed request before it can cause a single write error.
**One Liner**: Instead of reactive observability tools, Errorseal blocks malformed payloads before they reach your database — eliminating schema-mismatch rollbacks forever.
**Positioning**:
- **So That**: halt malformed data before it causes database corruption
- **Unlike**: legacy API gateways
- **For Whom**: backend engineering leads at mid-market fintechs
- **Category**: Inline payload enforcement for fintech
**Call To Action**:
- **Direct**: Deploy validation node
- **Transitional**: Download schema validator
**Failure Stakes**:
- Corrupted database records requiring manual SQL fixes
- Engineering hours lost to post-incident rollbacks
- Production downtime during critical transaction windows
**Transformation**:
- **To**: enforcing data integrity instead of cleaning up production corruption
- **From**: a lead engineer writing reactive validation scripts
**Controlling Idea**: Data validation belongs at the edge of the database, not in the post-mortem.
