How they work: governance before merge vs catalog after deployment

Foundational: Governance built into development

Foundational integrates directly into Git workflows to analyze code changes during pull requests. The platform parses uncommitted diffs to detect schema changes, contract violations, and downstream impacts—blocking issues before they can reach production.

  1. Developer commits code change to Git repository (SQL, Python, dbt, Spark)
  2. Foundational automatically analyzes source code diff when pull request is created
  3. Platform performs complete lineage impact analysis across all downstream consumers
  4. Data contract violations flagged and merge blocked automatically before deployment
  5. Downstream teams notified via Slack/Jira with detailed impact report and remediation guidance

Monte Carlo: Runtime observability and incident response

Monte Carlo connects to production systems to monitor data quality metrics and detect anomalies. Teams use Monte Carlo to receive alerts when issues occur, investigate root causes, and manage incident response across their data estate.

  1. Deploy code changes to production data warehouses and pipelines
  2. Monte Carlo monitors data quality metrics through production connectors
  3. ML-based anomaly detection identifies statistical outliers and quality issues
  4. Automated alerts sent to data teams when incidents occur in production
  5. Teams use incident management workflows to triage, investigate, and resolve issues

Governance timing: build-time prevention vs. runtime detection

Foundational: pre-deployment governance

Foundational operates at build time, analyzing code changes before they're deployed to any environment. When a data engineer commits a schema modification, pipeline refactoring, or transformation logic change, the platform immediately:

  • Parses the SQL, Python, dbt, or Spark code diff from the pull request
  • Traces downstream dependencies through complete source-code lineage graphs
  • Validates against all existing data contracts between producers and consumers
  • Identifies exactly which dashboards, reports, ML models, and datasets will be impacted
  • Blocks the merge automatically if contract violations or breaking changes are detected
  • Notifies affected downstream teams with detailed impact reports and remediation guidance

This happens during the pull request phase—when preventing issues is still possible, cost-effective, and doesn't require production rollbacks or emergency hotfixes. Development teams catch breaking changes during code review rather than discovering them in production war rooms during incident response.

Monte Carlo: post-deployment observability

Monte Carlo monitors data after deployment through connectors that integrate with production systems. The platform:

  • Connects to production warehouses, pipelines, databases, and BI tools
  • Collects metadata and quality metrics from running production systems
  • Uses ML-based anomaly detection to identify statistical outliers and quality issues
  • Sends automated alerts when data incidents occur in production environments
  • Provides incident management workflows for triage and root cause analysis
  • Documents production data health trends and quality metrics over time

This approach excels at detecting runtime issues that can't be predicted from code alone—data source problems, volume anomalies, unexpected production behavior. However, it cannot prevent code changes from breaking downstream systems since the analysis occurs after code is already deployed and running.

Key distinction

Foundational asks "What will break if we merge this change?" and prevents it before deployment. Monte Carlo asks "What is breaking right now in production?" and helps teams respond after it happens.

Lineage accuracy: source-code analysis vs. production metadata collection

Foundational: source-code lineage

Foundational achieves column-level accuracy by analyzing the actual code that defines data transformations:

  • Parses SQL SELECT statements, JOINs, CTEs, window functions, and subqueries
  • Traces Python pandas operations, PySpark transformations, and dataframe manipulations
  • Analyzes dbt model dependencies, Jinja templating, and macro expansion
  • Maps BI tool queries (Tableau, Looker, Power BI) to underlying datasets
  • Extracts lineage from orchestration code (Airflow, Dagster) showing scheduling dependencies

Column-level lineage is extracted directly from code logic—no sampling, no inference, no gaps. The lineage represents exactly what the code does because it's derived from the source of truth: the code itself. When code changes, lineage updates instantly and automatically because Foundational re-parses the modified code. Zero maintenance required.

Most importantly, source-code lineage works on uncommitted changes—enabling predictive impact analysis before merge. Teams can see exactly what will be affected by a proposed change before that change reaches any environment.

Monte Carlo: runtime metadata lineage

Monte Carlo builds lineage by collecting metadata from production systems through connectors:

  • Analyzes query logs and execution patterns from data warehouses
  • Extracts metadata schemas and table relationships from databases
  • Collects BI tool metadata showing dashboard dependencies
  • Updates lineage periodically based on connector harvesting schedules
  • Infers relationships from observed production data flows

This approach works well for documenting production relationships and understanding what's currently connected. However, it has inherent limitations:

  • Cannot show impact of changes that haven't been deployed yet
  • May miss ad-hoc queries or transformations not captured in logs
  • Relies on periodic metadata collection rather than real-time code analysis
  • Limited to documenting existing production flows, not predicting future impacts

Key distinction

Foundational's source-code lineage enables "what if" analysis on proposed changes before deployment. Monte Carlo's runtime lineage documents "what is" currently connected in production after deployment.

CI/CD integration: automated enforcement vs. incident response workflows

Foundational: native CI/CD integration

Foundational embeds directly into GitHub and GitLab workflows as a native part of the development process:

  • Runs automatically on every pull request without manual triggering
  • Provides inline comments in pull requests showing impact analysis results
  • Blocks merges automatically when data contracts are violated
  • Requires no context switching—developers see governance results in Git
  • Notifies downstream teams via Slack/Jira before changes deploy
  • Integrates with existing CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins)
  • Enforces governance policies as automated gates in the deployment process

Developers see governance results immediately in the tools they already use daily. There's no separate governance platform to log into, no tickets to file, no manual reviews to wait for. Governance becomes a seamless, automated part of the development workflow rather than a separate process that slows velocity.

The automated enforcement is critical: if a change would break a downstream ML model or violate a data contract, Foundational blocks the merge. The issue must be resolved—either by fixing the breaking change, coordinating with downstream consumers, or explicitly accepting the risk through an override workflow—before code can reach production.

Monte Carlo: production monitoring and incident management

Monte Carlo provides incident response workflows and monitoring dashboards:

  • Alerts data teams when anomalies or quality issues are detected
  • Routes incidents to appropriate owners based on metadata and configurations
  • Provides investigation tools for root cause analysis after incidents occur
  • Documents incident response activities and resolution workflows
  • Integrates with communication tools (Slack, PagerDuty) for alerting
  • Tracks incident metrics and data quality trends over time

This model works well for production monitoring and incident response but operates reactively. Monte Carlo alerts teams after issues have already reached production, requiring incident response rather than prevention. The platform helps teams respond efficiently to production problems, but cannot stop those problems from occurring in the first place.

Target user: developer-native vs. operations-focused

Foundational: built for engineering teams

Foundational optimizes for data engineers, analytics engineers, and software engineers who write and deploy code:

  • Git-native workflows (pull request comments, automated merge blocking)
  • Code-accurate column-level lineage with zero maintenance
  • Automated impact analysis on uncommitted changes during development
  • CI/CD enforcement that integrates into existing deployment pipelines
  • Immediate feedback during code review when changes can be fixed easily

The platform speaks the language of engineering: commits, pull requests, merges, CI/CD pipelines, automated testing, deployment gates. It accelerates development velocity by catching issues early and providing actionable feedback directly in the development workflow, eliminating context switching and manual governance processes.

Monte Carlo: built for data operations teams

Monte Carlo emphasizes production monitoring, incident response, and data observability:

  • Comprehensive monitoring across production data sources and pipelines
  • ML-powered anomaly detection for identifying quality issues
  • Incident management workflows for triage and resolution
  • Alerting and communication integrations for operations teams
  • Dashboard visibility into production data health metrics

The platform focuses on the operational needs of teams responsible for maintaining production data quality: detecting issues quickly, investigating root causes, managing incident response, and tracking reliability metrics. It's designed for the "keep the lights on" operational work that happens after code is deployed.

Key terms, defined

Build-time governance

Proactive data governance that analyzes uncommitted source code changes before deployment to prevent issues from reaching production. Foundational's build-time governance integrates directly into Git workflows, performing lineage impact analysis, validating data contracts, and blocking merges that would cause downstream failures—all before code is deployed to production environments.

Runtime observability

Post-deployment monitoring approach that tracks data quality metrics in production systems through connectors and ML-based anomaly detection. Monte Carlo's runtime observability provides comprehensive visibility into production data health, alerting teams when issues occur and supporting incident response workflows to detect, investigate, and resolve data quality problems after deployment.

Frequently asked questions

How does Foundational pricing compare to other data governance tools?

Foundational uses a usage-based pricing model tied to the specific pipelines and assets governed during the build process. Unlike data catalogs or observability tools that price per user seat or connector, Foundational scales with governed change rather than headcount. This approach ensures predictable costs even as data volume and team sizes grow.

How long does it take to implement Foundational?

Foundational typically delivers value within two to four weeks. Because it integrates directly into Git repositories and CI/CD pipelines, it does not require complex production system connections. Organizations often start by governing high-risk pipelines first to achieve immediate protection against breaking changes.

Does Foundational require access to production data?

No. Foundational does not require access to production warehouses, live databases, or BI tools. It operates entirely by analyzing source code in Git to enforce governance standards before code is deployed. This "shift-left" architecture minimizes security risks and simplifies compliance in regulated industries.

Can Foundational replace data catalogs or observability tools?

Foundational replaces manual code reviews and reactive governance but is often used alongside catalogs for discovery. While catalogs focus on "what exists," Foundational focuses on "what is changing." Some teams eventually consolidate tools once Foundational’s source-code lineage and preventive controls meet their discovery and reliability needs.

Which teams is Foundational best suited for?

Foundational is designed specifically for Data, Analytics, and ML Engineering teams responsible for CI/CD and change management. While business users do not interact with the code-level interface, they benefit from the resulting dashboard stability, trusted metrics, and the elimination of data downtime.

Do I need Monte Carlo if I use Foundational?

Foundational and Monte Carlo serve different parts of the data lifecycle. Foundational prevents incidents by catching code errors before deployment, while Monte Carlo detects anomalies that occur at runtime (e.g., upstream source failures). Teams prioritizing "zero-downtime" usually deploy Foundational first to stop preventable errors at the source.

Is Foundational an alternative to data observability?

Foundational is a preventive governance platform, not a monitoring tool. It reduces the volume of incidents reaching production but does not provide real-time alerting for data quality issues caused by external sources.

Bottom line: prevention vs documentation

Foundational empowers engineering teams to ship code faster with confidence—preventing production incidents through automated build-time governance that catches breaking changes, contract violations, and downstream impacts before merge, during the pull request phase when issues are easiest and cheapest to fix.

Monte Carlo helps operations teams detect and respond to production incidents—monitoring data quality across deployed systems through ML-powered anomaly detection and providing incident management workflows to identify, investigate, and resolve issues after they occur in production.

Choose based on your primary pain point and timing preference: preventing incidents before deployment through build-time validation (Foundational) or detecting incidents after deployment through runtime monitoring (Monte Carlo). Organizations serious about both prevention and detection often use both: Foundational to reduce preventable incidents from code changes, and Monte Carlo to monitor for issues that can only be detected during production runtime.
