Caseflood.ai, a voice‑driven legal AI platform in Y Combinator’s Winter '25 batch, has secured $3.2 million in seed funding from a syndicate that includes Acquisition.com, Y Combinator, Rebel Fund, Four Cities Capital, Elevation Capital, and others. This capital will enable the company to scale its voice‑AI agents, build out its engineering team, and expand features aimed at helping law firms convert more inbound leads into signed retainers.

Automating Legal Intake with Voice AI and Human Support

At the heart of Caseflood’s product is Luna, a conversational voice agent capable of holding 30+ minute conversations to qualify leads, schedule consultations, send SMS follow-ups, and close retainers with conversion rates 30% higher than traditional staff. It operates 24/7, seamlessly transitions to human agents for escalation, and integrates into existing firm tools like Clio for automated case setup and billing.

Law firms using Caseflood.ai report cutting operational costs by one-third while increasing average case value by 20%, making it more than just a tool - it’s a new revenue driver.

Redefining Law Firm Operations Through Persistent Intake Automation

Most firms rely on fragmented admin teams and expensive human intake processes. Caseflood.ai reimagines intake not as a burden, but as a scalable revenue workflow. Its ultra-value insight: rather than digitizing existing clerk workflows, they replaced them with an always-on, AI-first system that never drops leads.

This is the kind of shift founders can study deeply: true defensibility comes from building a system that eliminates recurring, high-friction tasks rather than supercharging them. With Luna embedded at the lead generation and conversion touchpoint, firms don’t just save time - they unlock revenue they previously lost. That means Caseflood is no longer a cost center - it becomes a structural sales asset. Firms keep paying because it consistently adds client intake without additional headcount.

Generating Trust and Growth via Hybrid Human-AI Design

While Luna handles the majority of conversations, human closers refine the experience in tougher cases. This hybrid model ensures quality and control while scaling to high volume. Firms report streamlined case setup, reduced follow-up friction, and improved client satisfaction - all through an experience built for speed and reliability.

By offering a unified AI + human system with CRM integration and automation of follow-ups, Caseflood.ai helps legal practices treat lead intake and conversion as core infrastructure - not an add-on.

Backed by Investors Betting on the AI-Fueled Future of Legal Ops

Acquisition.com and Y Combinator lead the round, reflecting belief that voice AI agents will redefine law firm economics. Acquisition.com founder Alex Hormozi called Caseflood “the future for law firms in intake and case management” and emphasized the platform’s potential to reduce reliance on costly staff hires.

This backing is rooted in results: firms using Caseflood.ai often convert more leads with fewer admin overheads, driving efficiency and revenue growth across the board.

Momentum in YC’s AI-First Law Tech Wave

Caseflood.ai emerged from YC W25 alongside other AI‑powered startups focusing on vertical agents - from law to sales and beyond. As the company turns theory into practice, it’s already closing retainers and processing calls for firms nationwide.

Founding Team Bridging AI Research and Legal Domain Need

Founded by Ethan Hilton, Tolen Schreid, and Ayushman Srivastava, Caseflood.ai combines Carnegie Mellon-level AI expertise with first-hand understanding of law firm workflows. They designed Luna specifically to emulate human conversation with machine consistency, lifting conversion without compromising care.

Their hybrid approach - AI agents plus human closers - mirrors the best of both worlds: automation where possible, personalized handling when required.

What’s Next: Scaling Voice Agents and Expanding Legal Workflows

Funds will be applied to enhance Luna’s language capabilities, support multilingual conversations, scale outbound outreach, and onboard more engineering talent. The roadmap also includes expansions into related firm workflows like case status updates, billing, and client engagement automation.

Caseflood.ai aims to become the default intake system for legal practices nationwide - operating like a research lab that focuses on human parity in voice AI while fundamentally changing the economics of legal operations.
