Class certification requires proving what's common. That means processing everything.

Class action lawsuits require establishing commonality across thousands of plaintiffs. That means processing terabytes of data — employment records, financial documents, communications, contracts. Firms specializing in class action law deal with massive data volumes to establish a class.

Employment Records

847,000 files

Pay stubs, performance reviews, job descriptions, termination letters

12 different HR system formats

Financial Documents

1.2M records

Payroll data, commission structures, benefits records, expense reports

Spanning 8 fiscal years

Communications

2.1M messages

Emails, Slack, internal memos, policy announcements

Across 47 departments

Plaintiff Coverage Gap

Records reviewed manually 8%
Plaintiffs with full analysis 3%
Commonality patterns identified Incomplete

Manual review can only cover a fraction of class action data, leaving certification arguments based on sampling rather than comprehensive analysis.

Manual review can only sample the data. With thousands of plaintiffs and millions of records, review teams cover a fraction of the total — and class certification arguments are built on incomplete analysis. Opposing counsel knows this.

Every month spent on manual review delays class certification — and gives defendants more time to challenge commonality. The faster you can demonstrate what unites the class, the stronger your position.

Time to Class Certification Analysis

Manual Review 6–12 months
Millions of records across thousands of plaintiffs Sample-based analysis — incomplete coverage
With Overstand Days
Every record, every plaintiff — analyzed comprehensively Full-class analysis ready for certification

From millions of records to class-ready evidence.

Overstand processes class action discovery the way the best litigators think — by finding what's common across every class member, not just a sample.

Build Class Certification Evidence

Structured evidence packages demonstrating numerosity, commonality, typicality, and adequacy — the four pillars of Rule 23.

Numerosity

Comprehensive class size analysis with demographic breakdowns, geographic distribution, and statistical evidence that joinder is impracticable.

Source-attributed to HR databases and employment records

Commonality

Specific shared questions of law and fact identified across the class, with evidence showing uniform policies and practices applied to all members.

Cross-referenced across all class member records

Typicality

Data-driven comparison showing named plaintiffs' claims arise from the same course of conduct and are typical of the class as a whole.

Named plaintiff claims compared to full class data

Adequacy

Evidence that named plaintiffs' interests align with the class, with no conflicts identified across the damages analysis.

Conflict-of-interest analysis across all class members
