Manual lease review doesn’t scale to deal timelines
Portfolio acquisitions create compressed diligence windows. The legal team gets handed 200, 500, sometimes 2,000+ leases and asked to surface deal-killer terms before the LOI expires. Manual abstraction at attorney and paralegal billing rates either blows the budget or blows the timeline — usually both.
The conventional response is to throw associates at it. The better response is to throw AI at it — but only if the output is defensible.
The engagement workflow
From kickoff to defensible deliverable, built around how diligence engagements actually run.
Engagement setup
We help you scope the engagement — portfolio size, required fields, deliverable format, timeline. Set up a dedicated workspace for the matter. Configure a custom field template tuned to the diligence questions specific to the deal.
Bulk upload and concurrent extraction
Upload the full document set — leases, amendments, addenda, acknowledgements. Abstria processes documents concurrently. A portfolio of 500 leases is hours to first-pass extraction, not weeks.
Surface the terms that matter
Configure portfolio-level queries to surface what the deal team needs: change-of-control restrictions, exclusivity provisions, kick-out rights, renewal options, percentage rent, gross-up clauses, signage commitments, parking allocations. Run portfolio-level reports across every extracted lease.
Defensible work product
Every extracted field traces back to the exact PDF location and surrounding clause text. Confidence scores guide review priority. Export the full diligence dataset to Word, Excel, or the format your downstream deal-team systems expect.
Three things diligence work product has to be
AI speed only matters if the output holds up after the deal closes. Abstria is built so it does.
Accurate
60+ CRE-specific fields with 95%+ extraction accuracy. AI-generated, attorney-verified. The dual-panel editor lets your team verify any field against source in one click.
Traceable
Every field links back to the exact lease, exact page, exact clause text. Source traceability isn’t an afterthought — it’s the architecture. When a counterparty asks where you got a term, you have the receipt.
Auditable
End-to-end version history. Every action attributed to a user with timestamps. Status workflows (Under Review → Reviewed). Full change history. Built for the post-close audit, the regulator inquiry, or the deposition that comes later.

Diligence-specific questions
What’s the largest portfolio Abstria has handled?
Talk to us about scale — bulk-processing capacity is one of the design points, and we’ve worked across portfolio-acquisition-scale engagements. Most realistic engagements fit comfortably within current capacity; we’ll confirm scope on your specific matter.
How long does setup take for a new engagement?
Setup is hours, not weeks. The custom field template, workspace provisioning, and user access can be configured the same day we kick off.
Can we configure custom fields specific to the deal?
Yes. Custom field templates let you add deal-specific extraction questions on top of the 60+ standard CRE fields. Useful for matter-specific clauses, jurisdiction-specific provisions, or special-situation diligence.
How does Abstria handle international leases?
The AI model is trained primarily on U.S. commercial lease language. International leases (UK, Canada, Australia) generally work well; jurisdictions with materially different lease structures may need custom configuration. Talk to our team about your specific portfolio mix.
Who at our firm owns the Abstria workspace?
Whoever you designate. Most firms put the engagement partner or the diligence lead as workspace owner, with paralegals and associates added as contributors. Roles are configurable and can change matter-to-matter.
Can we use Abstria for one diligence engagement, or do we have to commit to a subscription?
Both work. We support engagement-scoped pricing for firms running one-off diligence sprints, and subscription pricing for teams that run diligence regularly. Talk to our team — we’ll structure something that fits.
