Nexl vs InterAction: New vs Legacy - Which Wins?

If your firm is evaluating CRM platforms, InterAction is probably on the shortlist. It’s been a dominant large law firm CRM for decades, used by roughly three quarters of the Am Law 100 and a similar share of the largest firms globally. But dominance in the past does not automatically make it the right choice for your firm today.

Nexl is a newer platform for law firms that brings CRM, workspaces, marketing, and relationship intelligence together. Through tools, frameworks, and strategies, Nexl empowers firms to grow their business systematically and make growth a firmwide discipline.

Feature comparison

‍

How each platform approaches legal CRM

InterAction was launched in 1993 and acquired by LexisNexis in 2004. It is deeply established in the legal market, with strong contact management, relationship intelligence, and integration with LexisNexis content, including litigation analytics through Context.

The platform has historically been on-premises, with a cloud version (InterAction+) launched in 2023 targeting firms of 20 to 200 lawyers. While InterAction offers powerful data and analytics, it carries the weight of legacy architecture. Many firms report that lawyers find the interface cumbersome, and adoption remains a persistent challenge.

Nexl was built from the ground up as a cloud-native platform by former lawyers, marketers, and business development professionals. Its zero-data-entry CRM captures interactions automatically from email and calendar systems (without recording privileged information), removing the biggest adoption barrier in legal CRM. It also offers relationship intelligence, email marketing, event management, workspaces, and mobile as part of their platform.

Where Nexl pulls ahead

The core difference comes down to adoption and breadth. Nexl’s automatic interaction capture means lawyers benefit from the system without changing how they work. The “who knows who” feature maps connections across the entire firm, allowing opportunities to surface based on relationship data rather than manual input.

Nexl also includes built-in email marketing with drag-and-drop builders, event management with RSVP tracking, and collaborative workspaces for business development and marketing projects. InterAction typically requires third-party tools for email marketing and campaign management, adding complexity to the technology stack.

Implementation is another differentiator. Nexl deploys in weeks, while InterAction implementations, particularly for the on-premises version, can take months and requires dedicated IT resources, including a full-time CRM administrator.

Where InterAction holds its ground

InterAction’s strength lies in its depth of data and integration with the broader LexisNexis ecosystem. Firms already invested in LexisNexis research products benefit from seamless connections to litigation analytics, company intelligence, and news monitoring. For Am Law 100 firms with established InterAction deployments and dedicated CRM teams, the switching cost may outweigh the benefits of moving to a new platform.

InterAction+ also offers a cloud path for mid-sized firms, though the feature set and user experience are still catching up to fully cloud-native platforms.

Which firms should choose which

InterAction is best suited to Am Law 100 and large international firms that are deeply embedded in the LexisNexis ecosystem, have dedicated CRM administration teams, and can invest in ongoing maintenance and training.

Nexl is a better fit for medium to large enterprise firms that want high adoption from lawyers, fast deployment, and a single platform that combines CRM, relationship intelligence, email marketing, and collaboration. Mid-sized firms in particular will find Nexl delivers more capability at a lower cost.
