Deep research for class action law firms

Kalinda helps class action law firms qualify potential cases in minutes with AI. The nature of class action/mass torts involves thousands of cases for a single lawsuit. For every plaintiff (injured person), law firms involved in these cases compile everything from the products they used to the injuries they have. This data is extensive, granular, and buried deep in thousands of pages of medical, financial, and employment records and others. Kalinda extracts, summarizes, and aggregates data from these records for attorneys with AI. When scaled across an entire litigation, Kalinda works tirelessly and in parallel—turning a process that once took months into just a few hours. Kalinda provides firms with the equivalent manpower of hundreds of paralegals and legal nurses, allowing them to quickly determine which claimants are eligible and helping them file faster and in greater volume. To date, we’ve processed 600k pages of records and are live with 2 of the largest plaintiff law firms in the U.S!

TL;DR: Kalinda helps class action law firms qualify potential cases in minutes with AI — giving plaintiff law firms the equivalent manpower of thousands of paralegals and legal nurses.

Hey YC! We’re Sayan and Sohil. We’re brothers and the co-founders of Kalinda.







The Problem:

  • Millions of people every year join class action and mass tort lawsuits, hoping for justice and compensation.
  • For the law firm, this means verifying proof of usage and liability for each person—information often buried across thousands of pages of medical, pharmaceutical, and product records.
  • This compounds to several months of work for law firms just to determine who qualifies and who doesn’t.

Our Solution:

Kalinda…

  • Extracts proof of use, proof of injury, and other critical data points
  • Aggregates and correlates this data against lawsuit criteria
  • Generates a single report so plaintiff attorneys instantly know if a case is valid to file

All while doing this for each case, working tirelessly and in parallel.

When scaled across an entire litigation this turns a process that once took months into just a few hours.

As the lawsuit progresses and criteria change, we also help attorneys filter, categorize, and score to surface their strongest cases.

Where we’re at:  To date, we’ve processed 600k pages of records and are live with 2 of the largest plaintiff law firms in the U.S!

The Why & The Vision:

The plaintiff side of class actions and mass torts have struggled for decades now with what’s often called the “Field of Dreams” problem. Thousands of clients sign up for a lawsuit looking for restitution - only to leave the law firm buried in records, missing deadlines, and filing bad cases. When courts throw out these bad cases, it weakens the plaintiff side’s leverage in settlement negotiations.

With Kalinda, class action & mass tort law firms can now file valid cases faster and file more of them — fundamentally changing for the first time in 172 years not only how many people can get justice against corporate negligence, but how fast it’s delivered.

The Team:

  • Sayan (Co-founder & CEO) - did AI research at UC Davis’s LUKA Lab in instruction tuning optimization.
  • Sohil (Co-founder & CTO) - did AI research at Pacific Northwest National Lab

We’ve been collaborators together since Day 1 and even co-founded and scaled a STEM non-profit together to 7000 students worldwide.

Our Ask:

If you either have

  1. Been a part of a class action or mass tort in the past
  2. Know a friend or family who’s been a part of a class action or mass tort
  3. Know any attorneys, paralegals, associates at class action/mass tort law firms.
