Company profile

researched Aug 2026

Gain Life builds software intended to help people and organizations return to health, work, and productivity. Its claims automation platform is used by self-insured organizations, insurance carriers, and third-party administrators to reduce claim costs and improve the claims experience across multiple lines of business including workers' compensation, general liability, commercial auto, and disability.

The company's platform is presented publicly as Crosstie, described as one workflow platform for the full property and casualty claims lifecycle. It comprises eight modular solutions: intelligent document processing that extracts details from documents and routes work; intelligent voice that automates claim calls and escalates complex cases; claimant experience messaging and self-service updates; insurance-native ETL for ingesting and standardizing claims data; claim intelligence that surfaces insights and anomalies for adjusters; a customer portal for exchanging documents and updates; multimodal intake automating first notice of loss across voice, text, web, and email; and loss control for managing inspections and field data.

Additional capabilities described include configurable rules for personalized customer communication, continuous monitoring that flags potential delays or issues, and AI-generated next-best-action suggestions for adjusters. The platform emphasizes role-based permissions and guardrails for sensitive data, multilingual communication, and configurability without IT involvement.

Founding story

Founder and CEO Sean Eldridge traced the company's origins to his early career at Johnson & Johnson, where he worked on co-founding a metabolic consulting business serving medical and surgical weight loss practices. Interviewing patients there led him to conclude that lasting change came from an identity shift rather than the procedure itself, which shaped his focus on behavior change. Gain Life was founded by three alumni of Procter & Gamble's Future Works division and repurposed behavioral science techniques used in consumer packaged goods marketing to help people change their lives; the company later pivoted from weight loss to disability and return-to-work.

Business model

Gain Life sells its Crosstie platform to insurance organizations as configurable, modular software. Buyers can begin with a single workflow module addressing their most pressing operational bottleneck and expand across additional modules covering the claims lifecycle over time. The platform is positioned as an overlay to existing claims, policy, and RMIS systems rather than a replacement, and as a consolidation of multiple point vendors onto a single platform.

Software sold to insurance carriers, third-party administrators, and self-insured organizations, with adoption structured around modular solutions that customers can add over time.

Traction

The company reports enterprise deployments among large carriers, TPAs, and self-insureds. Publicly stated customer outcomes include identifying claims headed for litigation three or more weeks early, hours saved per adjuster per week, higher claimant engagement than standard portals, and independently analyzed customer data showing 25% cost savings on medical-only claims and $18,997 in savings per complex lost-time claim. MassMutual Ventures lists the company in its portfolio.

Market position

Gain Life positions itself as an enterprise-proven claims workflow platform used by large carriers, TPAs, and self-insureds, operating in the insurance automation segment alongside broader industry trends the founder described, including chat bots taking over mundane insurance tasks and algorithms gaining economic impact in insurance.

Crosstie is positioned as a single configurable platform spanning intake through settlement, replacing multiple point vendors, and built specifically for insurance workflows. Marketed differentiators include integration with existing claims, policy, and RMIS platforms without rip-and-replace, configuration of workflows and rules without IT bottlenecks, a stated 4-6 week go-live, role-based permissions and guardrails for sensitive data, multilingual support, and handling of enterprise claim volumes.

Technology

The platform applies AI and automation to claims workflows: document extraction and routing, voice automation for claim calls, multimodal first notice of loss intake across voice, text, web, and email, insurance-native ETL that ingests and standardizes claims data across systems, and claim intelligence that analyzes documents, messages, and calls to surface delays, missed steps, anomalies, and early risk signals. AI monitors workflows continuously to flag potential delays and provides next-best-action suggestions to adjusters. Access is governed by role-based permissions and guardrails so users and agents see only permitted data.

Go-to-market

The company sells directly to enterprise insurance organizations, using demo requests as the primary website conversion path and encouraging customers to adopt a single high-friction workflow first before expanding across the claims lifecycle. It cites independently analyzed customer outcome data and enterprise references among large carriers, TPAs, and self-insureds as supporting evidence.

Insurance carriers, third-party administrators, and self-insured organizations, across workers' compensation, general liability, commercial auto, and disability lines.

Geography

Headquartered in Boston.

History

The company was founded in 2014 by three alumni of Procter & Gamble's Future Works division, with Sean Eldridge as founder and CEO and David Merrill also named among its leaders. It initially built digital behavior change programs aimed at health outcomes such as weight loss, then pivoted toward disability and return-to-work applications, where its business grew through insurance customers. Its offering has since been presented publicly as Crosstie, an AI and automation platform spanning the property and casualty claims lifecycle.
