Seattle-based data-infrastructure startup Gable announced a $20 million Series A on March 31, 2025, led by Crane Venture Partners. The company is building a platform that uses data contracts and CI/CD checks to identify potentially breaking changes before they reach warehouses, dashboards, machine-learning systems, and other downstream consumers.
Gable’s approach is aimed at a familiar engineering problem: an application can continue working after a field is renamed or its meaning changes, while the data products that depend on that field fail later. Gable wants those compatibility checks to happen during development instead of primarily after a production incident.

Gable said it will use the capital to accelerate product development and expand its engineering, product, and customer-success teams. The company has named Glassdoor, Grab, and x15ventures among its customers or early users. It also said its community exceeded 15,000 data practitioners, a company-reported engagement figure rather than an independently audited user count.
#1 Best Overall
Gable was founded by former Convoy data leaders. Its principal founders and early leaders are CEO Chad Sanderson, CTO Adrian Kreuziger, CPO James Frost, and founding engineer Daniel Dicker. The company says the founding group has more than 50 years of combined data-platform experience. More details are available on Gable’s About page.

What Gable actually sells
Gable describes its product as a Data DevOps or “shift-left” platform. The central product concept is a data contract: an explicit, API-like specification for a data asset.
Recommended Free Tools
A contract can describe:
- field names and data types;
- required and optional fields;
- business meaning and descriptions;
- ownership and version information;
- compatibility expectations;
- links to a repository or commit; and
- known downstream assets or consumers.
Gable’s documentation explains that proposed changes can be compared with registered contracts to identify possible violations before code is merged or deployed. The platform is therefore not merely a catalog or a dashboard. Its key value proposition is making data compatibility part of an engineering workflow.
How a data change can break a business
Consider an application that emits customer events. The application team changes customer_id from a required string to a nullable integer. The application may still build, pass its own tests, and run normally.
Downstream systems may not be so fortunate:
- A warehouse model expects the old type.
- A dashboard joins the field to a customer table using string values.
- An ML feature pipeline rejects nulls.
- A finance workflow silently drops records it cannot match.
- The failure is discovered only after data has been ingested or consumed.
The same problem can arise when a field is renamed, removed, or given a new business meaning. A field called status might originally mean “payment status” but later be repurposed to mean “account status.” The schema still looks valid, yet the data is no longer compatible with the consumer’s assumptions.
Gable’s model asks the producer to communicate the change before deployment. A contract check in a pull request or CI pipeline can flag the potential break while the owning engineering team still has context and can coordinate a migration.

How the platform works
Gable’s documented workflow includes registering data assets, defining or generating contracts, storing and serving those contracts through an authenticated API, and checking proposed changes through the Gable CLI or GitHub Actions.
Documented asset and format support includes:
- PostgreSQL, MySQL, and Microsoft SQL Server;
- Protobuf, Avro, and JSON Schema;
- Python objects, PySpark, and TypeScript;
- S3 assets; and
- other asset types listed in the API schema, including Snowflake, BigQuery, dataframes, Kotlin, Swift, PHP, and Go.
The last group should be treated carefully: appearing in an API schema is not necessarily the same as being a fully documented or generally available product capability. Buyers should confirm current support for the specific systems they use.
Rank #2
A basic installation begins with the documented Python package:
pip install gableFor relational databases, Gable documents a proxy-database or local/test-database workflow. The proposed migration is applied to a test environment, and the resulting asset is checked against registered contracts. This can reduce the need to query ordinary production tables directly.
Gable’s documentation includes an illustrative command using gable data-asset check, but the example combines a PostgreSQL proxy container with MySQL source options and port 3306. It should therefore be adapted to the customer’s actual database rather than copied as a universal production command.
For source-code and schema checks, the relevant repository must be available locally or in the CI/CD runner. Gable documents GitHub Actions and API-key authentication for its platform integrations.
What “shift left” means
In data management, “shift left” means moving checks earlier in the development lifecycle:
- from production dashboards to application code;
- from incident response to pull requests;
- from downstream discovery to upstream ownership; and
- from repairing broken pipelines to reviewing compatibility before deployment.
Gable’s argument is that software teams should treat the data produced by their services as part of the product. If other teams depend on that data, the producer needs visibility into those dependencies before changing the source.

Gable’s descriptions of itself as the first or world’s first Data DevOps platform are company positioning claims, not independently established industry facts.
What data Gable accesses
Enterprise buyers will need to examine Gable’s deployment and security model closely. According to the company’s documentation:
- the CLI processes only files explicitly provided to the registration command;
- relational-database checks collect metadata such as table names, column names, field types, and constraints;
- the product does not require ordinary
SELECTaccess to production table data; and - a proxy, test, or staging database can be used for proposed relational changes.
Gable says contract definitions and metadata are sent through an authenticated API. Its documentation also says static analysis may bundle selected code for analysis without persisting the code on Gable’s servers. That is different from saying Gable never receives source code during processing, and the company’s current security and retention policies should be reviewed before deployment.
For a serious evaluation, buyers should ask about encryption, retention, deletion, data residency, intellectual-property protections, whether analysis can run entirely inside the customer’s environment, and how contracts can be exported if the customer leaves.

Gable is not a complete replacement for data observability. Observability platforms such as Monte Carlo, Soda, and Bigeye generally focus on detecting problems in data that is already moving through pipelines or stored in analytical systems.
Gable’s differentiating pitch is earlier intervention: checking the producer’s proposed schema or code change before it reaches those systems. In a mature data organization, both approaches may be useful. Contract checks can prevent known compatibility failures, while runtime monitoring can catch freshness, volume, distribution, pipeline, and other problems that contracts cannot predict.
dbt and similar transformation tools may be a better fit when most quality problems begin inside the warehouse or transformation layer. Internal teams can also implement contracts themselves using Protobuf, Avro, JSON Schema, Git-managed files, and custom CI checks. Gable’s value proposition is packaging contract management, asset registration, change detection, API access, and collaboration into a managed product—not making data contracts impossible to build without it.
Important limitations
Contracts can become stale
A passing schema check does not prove that the data remains semantically correct. Units, event timing, null behavior, allowed values, deduplication rules, and business definitions can change without an obvious schema change.

Gable can identify dependencies only when assets are registered, contracts are defined, and relevant repositories and deployment paths use the checks. Unregistered datasets, ad hoc queries, spreadsheets, third-party SaaS data, and bypassed pipelines can remain outside the protection boundary.
Checks can produce false positives or false negatives
Strict rules may block harmless additive changes, while a schema-compatible change may still cause a business failure. Teams need compatibility policies, versioning, and a process for deciding which changes are blocking and which are advisory.
The proxy model adds operational work
A proxy database can limit production access, but migrations must accurately reproduce the proposed schema. Differences between local, test, and production environments can undermine the result.
It does not solve every data incident
Gable is not designed to automatically fix bad source data, late-arriving data, unrelated pipeline outages, incorrect business logic, unauthorized access, or consumers that were never registered. It aims to catch a specific class of contract and compatibility problems before deployment.

What evidence supports the pitch?
In its financing announcement, Gable said early adopters saw incident-resolution time improve by up to 70% and development cycles for data-dependent features accelerate by 50%.
Those are company-reported figures. The announcement does not provide a sample size, measurement period, baseline, control group, customer-by-customer breakdown, or definitions for “incident resolution” and “development cycle.” They should be read as reported outcomes, not independently verified performance benchmarks.
Gable’s public changelog shows development around data-asset statistics, S3 registration, asset changelogs, contract subscriptions and notifications, contract archiving and unpublishing, and contract generation from data assets. The latest dated public update identified in the supplied materials is November 7, 2025, for generating contracts from data assets; that should not be treated as proof that no later updates exist.
Who should consider it?
Gable may be a strong fit for an organization where application teams produce event or operational data consumed by many downstream teams, schema changes are frequent, and engineering teams already use GitHub, CI/CD, test databases, or infrastructure-as-code workflows.
It may be a poor fit for a small team with few producers, an organization without reliable ownership of upstream services, or a company whose main need is runtime freshness and anomaly monitoring. It is also less useful when most important data comes from third-party systems that the organization cannot modify at the source.
Before buying, teams should ask:
- Which integrations and asset types are generally available today?
- Can validation be blocking, advisory, or configured by repository?
- How are additive, breaking, and semantically breaking changes classified?
- How are downstream consumers discovered?
- What happens when a consumer is outside the platform?
- What are the retention, residency, encryption, and deletion policies?
- Is fully local static analysis available?
- Does pricing depend on users, assets, repositories, checks, environments, or data volume?
- Can contracts be exported?
- Which customer outcomes can be independently validated?
Gable’s public product materials direct prospects to request a demo rather than publishing a public price list, so pricing should be treated as sales-led unless the company confirms otherwise.
The larger significance of the round
The financing matters less because it creates a new kind of data contract and more because it signals continued investor interest in moving data reliability closer to the systems that produce data.
Data contracts can be implemented with open standards and internal tooling. The difficult part is organizational: identifying owners, documenting meaning, mapping consumers, enforcing checks, and resolving changes before they become incidents. Gable is trying to turn that process into a routine software-development control.
Whether the strategy delivers depends on adoption and coverage. A contract that runs on every relevant data-producing service can prevent expensive surprises. A contract that covers only a small, unowned portion of the estate becomes another piece of documentation. That distinction—not the funding headline alone—will determine how meaningful Gable’s shift-left approach is for buyers.
