Document automation, templates aware of the matter, versions the audit team can defend.
Law firms run on documents. Engagement letters, NDAs, motions, closing binders. We build the automation layer that pulls matter data into branded templates, ships them through e-sign, and tracks every version with an audit trail a reviewer can defend.
What we build
Matter-aware templates, not generic mail merges
Templates pull from the matter's structured data, parties, jurisdictions, fee structures, defined terms, and render the right clauses for that matter type. New matter types are template authoring, not code changes.
Clause libraries with provenance
Reusable clauses live in a versioned library with author, approval date, and last review. Templates reference clauses by ID; a clause update propagates with a one-click batch re-render of dependent drafts.
E-signature through DocuSign + HelloSign
Single integration layer abstracting the e-sign provider; firms keep their existing vendor or switch without re-platforming. Signing status webhooks land in the matter timeline; bounced sends route to fee earners with the reason.
Audit trail per document, per clause
Every edit is a versioned diff with actor + timestamp. Approval workflows for partner sign-off run inside the system; the audit log shows who reviewed and when, not 'who probably approved this'.
PDF pipeline that handles redaction
Redactions are real (the text is removed, not just black-boxed), pagination respects pleading rules, exhibit numbering renumbers automatically when documents are inserted or removed.
Matter portal for clients
Clients see only their matter's documents, sign through a branded portal, get notified of status changes. The portal respects per-matter access lists so co-counsel and opposing parties see different slices.
Where this fits
Your fee earners are spending three to five hours per matter copy-pasting between Word templates and the case management system.
Engagement letters and NDAs go out inconsistently because every partner has their own version of the template.
Your firm is hitting the scale where 'the paralegal who knows the templates' has become a single point of failure.
