Rel Labs brings legal tech innovation is now live, as Relativity — a global leader in legal technology — formally announces Rel Labs, an investment arm and innovation hub to accelerate transformation in legal data intelligence. This initiative seeks to expand the capabilities of its core platform, RelativityOne, while fostering partnerships with startups and existing developer partners.
The hub will work closely with The LegalTech Fund (TLTF) to identify and support the most promising legal tech startups. As part of this effort, Relativity is enhancing its Developer Program (launching a new structure in 2026) to provide clearer growth pathways, increased support, and stronger collaboration opportunities for its developers. With over $170 million earmarked for research and development (R&D) across 2025, the company aims to back both seasoned software vendors and breakthrough entrepreneurs. PR Newswire+1

Developer Program Revamped
Under Rel Labs, Relativity is revamping its Developer Program for 2026. Developer partners will be classified into three categories:
- Innovators — independent developers building applications or extensions for RelativityOne.
- System Integrators — groups that deliver custom implementations and workflows.
- Strategic Partners — those co-developing solutions with Relativity itself. PR Newswire+1
This new structure aims to provide clearer benefits and growth paths, helping devs scale solutions and align more closely with what customers need. The developer community, counting over 50 existing partners, stands to gain more resources, better support, and enhanced access to Relativity’s platform and AI tools. PR Newswire
Investment and Ecosystem Growth
Rel Labs is not just an internal hub — it involves capital investment, startup backing, and ecosystem building. The company will fund new strategic partnerships, strengthen current ones, and support startups via TLTF. This approach promises to deepen the impact of innovations and ensure that RelativityOne stays at the forefront of legal tech trends. PR Newswire+1
Relativity’s $170M+ R&D spend for 2025 underscores that this initiative is well-resourced. That budget supports both platform development and the growth of new features, including AI-powered capabilities, better data intelligence, and tools for compliance and breach investigations. PR Newswire
