After gaining early access to GPT-4, Jake Heller and his team realized its transformative potential for the legal industry. Within 48 hours, they decided to shift all 120 employees to focus entirely on building a new product, Co-Counsel, leveraging GPT-4. This decision was driven by the technology's ability to perform tasks that previously took a full day in just a minute and a half, offering a significant competitive advantage.
Case Text's valuation skyrocketed from $100 million to $650 million within two months of launching Co-Counsel, a product built on GPT-4 technology. This rapid increase in valuation led to a successful acquisition by Thomson Reuters.
Case Text had been investing in AI and natural language processing for over a decade, building close relationships with research labs like OpenAI. This groundwork allowed them to quickly recognize the potential of GPT-4 and pivot their entire company to leverage the technology, giving them a significant head start in the market.
Convincing the team to pivot to GPT-4 was challenging because many employees had seen previous pivots fail. Jake Heller led by example, building the first prototype himself and involving customers early to demonstrate the technology's potential. Seeing customer reactions during Zoom calls helped change skeptical minds quickly.
Case Text implemented a test-driven development framework, creating thousands of tests for each prompt to ensure accuracy. They broke down complex legal tasks into step-by-step prompts, ensuring the AI could handle nuanced legal work without hallucinations. This rigorous approach made Co-Counsel reliable enough for mission-critical legal tasks.
Vertical AI agents, like Case Text's Co-Counsel, are tailored to specific industries, offering deep domain expertise. Case Text's focus on the legal industry allowed them to build a product that significantly improved legal workflows, leading to their $650 million acquisition by Thomson Reuters. This success highlights the potential of vertical AI agents in creating billion-dollar SaaS opportunities.
Case Text's experience with earlier models like GPT-3.5, which often hallucinated and lacked precision, taught them the importance of rigorous testing and prompt engineering. When they gained access to GPT-4, they applied these lessons, breaking down tasks into smaller, testable prompts to ensure accuracy and reliability in their legal AI assistant, Co-Counsel.
Startups can learn the importance of early investment in AI, the value of test-driven development, and the need to pivot quickly when transformative technology emerges. Case Text's success also highlights the potential of vertical AI agents in creating significant market opportunities by solving specific industry pain points.
As LLMs continue to improve, it's clear that vertical AI agents are key to the next generation of billion-dollar SaaS opportunities.
In this episode of the Lightcone, we sat down with Jake Heller, the co-founder and CEO of Castext— which sold to Thomson Reuters for $650 million in 2023— to discuss what it takes to build a successful vertical AI company.
