Below is a practical comparison between Warrant and Haast, two platforms that address marketing compliance, but through fundamentally different models.

Warrant positions itself as a compliance review tool for financial services, and real estate, with a strong emphasis on pre-publish checks powered by a large rule library. 

Haast, by contrast, is built as an enterprise compliance operating system - embedded with bespoke policy enforcement, global governance, and continuous monitoring of live content across channels.

Top Features Comparison

Implementation and Set-Up Comparison

Warrant’s implementation is rule-library led. Teams deploy a broad set of pre-configured policies (1000+ as per their website) derived from regulatory enforcement actions and industry best practices. Administrators can toggle rules on or off and add a limited number of custom policies to extend coverage.

This enables fast setup and immediate pre-publish reviews. However, the underlying enforcement logic remains generic by design. Risk is assessed against a shared rule corpus, not against the organization’s full internal governance model. Product nuance, internal risk tolerance, and market-specific interpretations aren’t embedded.

Haast takes a fundamentally different approach. Implementation is bespoke from day one. Over an 8–12 week period, Haast’s legal implementation team works directly with your General Counsel and compliance leaders to translate internal policies line-by-line across products, channels, and jurisdictions.

There is no default rule library layered on top. Your governance framework is the system.

The result is AI that mirrors how your lawyers actually review content - and applies that logic consistently before publication and across all live channels.

Where Warrant standardizes compliance for speed, Haast builds compliance infrastructure for accuracy and scale.

Support and Onboarding Comparison

Warrant provides structured onboarding focused on activating its rule library and configuring pre-publish workflows. 

Haast’s legal implementation team works directly with internal stakeholders to encode your policies, precedents, and risk posture into enforceable AI frameworks. A dedicated Customer Success Manager then supports rollout across teams, markets, and brands.

Training Requirements Comparison

Warrant requires minimal training due to its template-driven model, meaning reviewers can begin quickly. 

Haast requires more upfront training because the AI enforces your policies, not a generic rule set. Over time, the system learns from legal decisions, exceptions, and escalations - becoming progressively more aligned with your organization’s governance standards.

Integration and Workflow Comparison

Warrant integrates with Google tools, Slack, and Webhooks - sufficient for pre-publish review workflows in narrow use cases.

Haast integrates across the full enterprise content lifecycle, natively embedding into creative tools, approval environments, and monitoring systems. These integrations enable continuous oversight of live websites, social channels, and partner content.

Warrant helps you check what’s about to go live. Haast helps you govern what’s about to go live, what's already live - and what changes tomorrow.

Warrant

Teams in financial services or real estate seeking fast, pre-publish compliance checks using a broad, generic rule library.

Haast

Best for enterprise organizations that need:

• Compliance bespoke to their internal policies - not generic rules. AI that mirrors how your in-house lawyers review content within ~12 weeks

• True enterprise scale - unlimited users, teams, brands, and markets without re-templating

• Full compliance coverage - pre-publish checks and continuous monitoring of live content across channels

If compliance varies by product, market, or risk tolerance,  and if live content matters, Haast is built for that reality.

Bottom Line

Both Warrant and Haast offer AI-assisted compliance review. They are not built for the same problem.

Choose Warrant if you want:

• Fast pre-publish checks

• A large, generic rule library

Choose Haast if you want:

• Compliance bespoke to your organisation from day one

• Pre-publish and post-publication monitoring
