The way businesses communicate has changed faster than the tools built to preserve those communications. For legal, compliance and records teams, eDiscovery workflows centred on email and static repositories are no longer fit for purpose. Relevant evidence now sits in persistent chat, voice and video calls, meeting transcripts, screen shares, file attachments and, increasingly, AI interactions.
According to Theta Lake, the answer lies in a modern approach to eDiscovery and legal hold that brings unified preservation, deeper investigation and Early Case Assessment (ECA) to every channel.
Organisations have always had to preserve information when litigation, regulatory probes or internal audits arise. What has shifted is the evidence itself. Platforms such as Microsoft Teams and Zoom, along with AI assistants including Microsoft Copilot, Zoom AI, OpenAI and Anthropic, have reshaped workplace communication. A single decision might begin in an email, continue in chat, move into a video call, generate a transcript and finally be summarised by AI.
Reviewing these records in isolation strips away context, while surging volumes make collecting everything before establishing relevance both costly and inefficient.
AI has also created an entirely new class of enterprise record. Prompts, responses, generated content and summaries often capture business decisions, internal advice and confidential information. Because generated or inferred content needs extra context during an investigation, legal teams must treat it with the same rigour as traditional communications.
Legacy legal hold processes create clear gaps. Collaboration platforms offer native retention tools, but each manages preservation independently, leading to fragmented oversight, licence dependencies and heavier administrative workloads. Siloed records make it harder to reconstruct a full narrative.
Meanwhile, older workflows often require exporting vast datasets into downstream platforms before teams know what matters, adding hosting costs, data movement risk and processing fees before ECA has even started.
Theta Lake argues a modern solution should provide a single system of record with an investigation workspace, unified custodian and group holds across all modalities, and automated holds triggered by content and metadata rules at the point of capture. Communications should be preserved and replayed in their native format rather than converted into email threads.
Granular search using more than 100 filters, connection graphs mapping relationships between individuals, and targeted exports in Concordance.dat format with native files and extracted text enable smooth handover to review tools such as Relativity and DISCO.
Crucially, modernisation does not mean abandoning established review platforms. Instead, firms should build a centralised preservation and investigation layer: unifying capture across collaboration apps, automating matter and hold management, conducting ECA before downstream review, and exporting only vetted collections.
In a fast-moving, multi-channel and AI-driven environment, fragmented holds and premature bulk exports leave organisations exposed to rising costs, compliance gaps and lost context. A centralised approach allows legal teams to preserve with confidence, surface insights quickly and export only what truly matters.
