What do we mean by giving power back to clients, and joy back to lawyers?
The legal sector is stuck in the Jurassic era. Companies, individuals, and governments collectively spend vast sums on legal fees each year to fight disputes. Many law firms bill by the hour, which incentivises them to produce a high volume of work over a long timeline—leading to disputes that can drag on for years.
Large case files make manual analysis, research, and drafting inefficient, so clients often feel overcharged and under-heard, while lawyers burn out. Law firm profit margins can be as high as 80%, signalling a sector ripe for disruption.
Thanks to AI, clients can regain control over a case’s speed, cost, and outcome, while lawyers – freed from the heavy lifting – can focus on strategy and rediscover the joy in their work.
Sisu is more than a legal AI platform—it’s your ally in transforming disputes into faster, better outcomes. Ready to see how it works?
