What is Cruxi?

Cruxi is a specialized AI platform built for medical device regulatory teams that streamlines the FDA submission process. Founded in 2024 and based in New York, the platform ingests FDA regulations, guidance documents, product codes, standards, MAUDE adverse event data, recalls, and prior 510(k) submissions to power intelligent regulatory workflows.

The medical device regulatory process is notoriously complex and time-consuming. A typical 510(k) submission can take months of preparation and tens of thousands of dollars in consultant fees. Cruxi aims to compress this timeline dramatically by automating the most labor-intensive steps: device classification, predicate device identification, substantial equivalence analysis, and submission document generation.

The platform supports 14 regulatory services spanning FDA, EU MDR, UKCA, Health Canada, and Australia TGA, making it a comprehensive solution for companies seeking regulatory clearance across multiple markets. With a 4.8/5 rating from 150 reviews and a team of 11-50 employees, Cruxi has quickly established itself as a serious player in the regulatory technology space.

Key Features

1. AI-Powered Device Classification

Cruxi's AI analyzes your device description and automatically identifies the correct FDA product code and regulatory pathway. The system cross-references the FDA's device classification database, recent submissions, and guidance documents to recommend whether your device requires a 510(k), De Novo, PMA, or other pathway.

2. Intelligent Predicate Device Finder

Finding the right predicate device is one of the most critical and time-consuming steps in a 510(k) submission. Cruxi's AI scans the entire FDA 510(k) database to identify substantially equivalent devices, analyzing intended use, technological characteristics, and performance data to suggest optimal predicates.

3. Automated Refuse-to-Accept (RTA) Checks

Before you submit, Cruxi runs automated RTA validation checks against your submission package. This pre-flight check catches the common errors that cause FDA to refuse submissions, saving weeks or months of delays. The system validates completeness across all eSTAR sections.

4. eSTAR Editor with Intelligent Drafting

The built-in eSTAR editor provides a professional submission authoring environment with AI-powered drafting assistance. The AI generates initial drafts for each section based on your device information, predicate analysis, and applicable standards, which regulatory professionals then review and refine.

5. Compliance Advisor

Cruxi's AI-powered compliance advisor provides real-time guidance on regulatory requirements. It cross-checks your submission against applicable FDA guidance documents, standards (IEC, ISO), and recent enforcement trends to flag potential compliance gaps before they become problems.

6. Global Regulatory Support

Beyond FDA, Cruxi supports EU MDR Technical Documentation, UKCA Dossiers for the UK market, Health Canada Medical Device Licence applications, and Australia TGA ARTG registrations. This multi-market capability eliminates the need for separate tools or consultants for each jurisdiction.

Sign up at cruxi.ai with your email. No credit card required to start. The platform offers a free start option to explore the interface and basic features.

Step 2: Describe Your Device
Enter your device description, intended use, and technological characteristics. The more detail you provide, the more accurate the AI's classification and predicate recommendations.

Step 3: Get AI Classification and Pathway
Cruxi analyzes your device and recommends the regulatory pathway (510(k), De Novo, PMA, etc.) with the appropriate product code. Review the AI's recommendation against your own understanding.

Step 4: Find Predicate Devices
The AI identifies and ranks potential predicate devices from the FDA database. Review the substantial equivalence analysis and select the most appropriate predicates for your submission.

Step 5: Build Your Submission
Use the eSTAR editor to build your submission package. The AI drafts initial sections, and you refine them. Run RTA checks throughout to ensure completeness before final submission.

Pricing Plans

Plan	Launch Promo	Regular Price	Includes
Full Workflow	$100	$1,000	All 14 services, complete submission
Per Service	$20/service	$200/service	Individual service access
Free Start	$0	$0	Explore platform, no card required

Cruxi's pricing is remarkably competitive for regulatory technology. The current launch promotion (valid through May 21, 2026) offers 90% off for the first 3 months, bringing the full workflow cost to just $100 versus the regular $1,000. Individual services can be purchased at $20 each (vs. $200 regular). Compared to regulatory consultant fees of $15,000-$50,000+ per submission, even the regular pricing represents massive cost savings.

Pros and Cons

Pros

✓ Dramatically reduces 510(k) preparation time
✓ 14 regulatory services across FDA and global markets
✓ AI predicate finder searches entire FDA database
✓ Automated RTA checks prevent costly submission rejections
✓ 90% launch discount makes it extremely affordable

Cons

✗ Still requires regulatory expertise to validate AI outputs
✗ Young company (founded 2024) with limited track record
✗ Regular pricing ($1,000/workflow) is steep for startups
✗ Niche market limits user community and third-party resources
✗ AI classification needs human verification for novel devices

Cruxi	$100-$1,000	FDA 510(k) AI	This review
Rimsys	Custom	Regulatory information mgmt	Enterprise regulatory teams
RegDesk	Custom	Global regulatory intelligence	Multi-market regulatory strategy
Traditional Consultants	$15K-$50K+	Full-service regulatory	Complex or novel device submissions

Rimsys (Custom pricing) provides a comprehensive regulatory information management system for larger teams managing multiple products and submissions simultaneously.

RegDesk (Custom pricing) focuses on regulatory intelligence across 120+ markets and is ideal for companies with complex global regulatory strategies.

Traditional Consultants ($15K-$50K+) remain the gold standard for complex or novel device submissions where AI assistance may not be sufficient.

Final Verdict: Is Cruxi Worth It?

Cruxi represents a genuine breakthrough in regulatory technology for medical device companies. The platform does in minutes what typically takes regulatory professionals months: device classification, predicate identification, and initial submission drafting. At the current launch pricing of $100 for a full workflow, it is an extraordinary value compared to consultant fees that routinely exceed $25,000.

The key caveat is that Cruxi augments rather than replaces regulatory expertise. The AI outputs still require validation by experienced regulatory professionals, especially for novel or complex devices. But for standard 510(k) submissions, the time and cost savings are substantial. Early adopters who lock in the launch pricing will get exceptional ROI.
