For mid-sized law firms

Big-firm capability,
mid-sized budget.

Subsumio gives a 10-50 lawyer firm the knowledge infrastructure of a 200-lawyer firm — every matter, deadline and brief indexed and answerable, with confidentiality by architecture.

The mid-sized firm's challenge

Doing more with less

You compete with big firms for the same clients but have a fraction of the headcount. Every efficiency gain is a competitive advantage.

Knowledge is fragmented

Each lawyer maintains their own system — folders, notes, inbox rules. When someone's on vacation or leaves, their matters become black boxes.

IT is a constraint, not an enabler

No dedicated IT team for legal tech. You need tools that work out of the box, not projects that need a six-week implementation cycle.

Outsized impact for lean teams

One shared brain

Every lawyer's matters, briefs and notes in one indexed workspace. A new associate finds the 2023 brief in seconds, not by asking three people.

Deadline control for the whole firm

Centralized deadline calendar with per-lawyer views. Statutory computation per ZPO/BGB/ABGB — no more spreadsheet tracking.

Conflict check in seconds

New client or opposing party screened against the entire case base before acceptance — automated, not manual.

WhatsApp copilot for every lawyer

Time booking, document filing, voice notes from the phone. The tool your lawyers actually use daily, not another system they avoid.

Time, invoices & DATEV

Firm-wide time tracking, invoicing and DATEV export. Admin work that used to eat Friday afternoons, done in minutes.

EU-hosted or self-hosted

No US cloud, no US model provider. EU hosting with DPA, or self-host on your own hardware with your own keys.

The force multiplier your team needs

99.8% Recall@8 on LongMemEval (500 questions) means your team finds what matters — every time. When a 15-lawyer firm finds the decisive precedent in seconds, it performs like a 50-lawyer firm.

Questions, answered

A pilot with 2-3 lawyers takes a day. Full firm rollout typically takes a week — your team indexes existing matters at their own pace.

Firm is €999/month, can be canceled monthly and includes five users. Bulk ingestion, shared firm knowledge, roles and WhatsApp workflows are included.

Absolutely. Start with Pro for one lawyer, upgrade to Team when ready. All data carries over — no migration, no downtime.
