Today vs tomorrow

Outgunned today. A factory tomorrow.

Today

You're outgunned.

The opposing party has 5 senior associates billing 80 hours each on the claim. You have you, two juniors, and a partner running three other matters. Excel and Outlook. 47 active matters. The math doesn't work — you lose on volume, not on argument.

Friday at 5pm: deadline closing on a forfeiture you only just spotted in a buried email thread.

With Vonbuild

You have 1,000 workers.

Vonbuild isn't a chatbot. It's a factory. You don't get a new dashboard — you get an elastic workforce that operates inside your existing DMS, Outlook, and matter folders. When 400 documents need reconstructing, 412 workers spawn. The factory scales to the matter.

Monday 8am: chronology, evidence chain, draft response on your screen. Friday: you walked into mediation prepared.

The cross-functional superpower

You don't get a calculator. You get the whole firm.

AEC problems don't live in silos. A variation order is a Legal problem, an Operations problem, AND a Procurement problem. Vonbuild gives you access to every Master — they work together on one matter.

Master Legal

Reads the variation order. Flags the deadline.

A new Variation Order #47 lands in the matter folder. Master Legal extracts the contractual reference (CCAG Art. 9.2), identifies the 15-day notification window, drafts the contractual position. Trigger: 9am Monday.

Master Operations

Pulls the site events that triggered it.

Legal calls Operations. Operations queries the project's daily reports, RFIs, and site photos — identifies the 12 events between Feb 4 and Apr 15 that constitute the chain of causation. Returns the evidence pack to Legal. Elapsed: 8 minutes.

Master Procurement

Quantifies the cost exposure.

Procurement cross-references already-ordered materials against the new scope. Quantifies what's recoverable vs unrecoverable. Drafts the cost recovery quantum. Returns the number to Legal. Elapsed: 12 minutes total.

Result · 4 hours across 3 Masters

vs. 2 weeks of solo associate time

A bulletproof claim file. Built once. Across three departments.

Contractual position (Legal) + evidence chain (Operations) + cost quantum (Procurement) — assembled into one filing-ready claim file. €2.1M recovery defensible. You spend the morning reviewing the file and the strategy, not assembling it. Friday: filed, defensible, on time.

Live process · Legal cascade

One command. Five legal agents. Contract analyzed.

A direct instruction to Master Legal spawns five specialized agents in parallel. Ninety seconds from command to a signed risk report. Two deadlines auto-tracked.

Signal

An event arrives at 14:32.

Any source can fire it: a file dropped in OneDrive / Google Drive / any drive, an email landing in Outlook, a scheduled task firing, or you pressing a button. In this scenario, an event arrives via YOU.

Routing

MASTER LEGAL routes.

It classifies the impact across 21 semantic categories and dispatches to the 5 specialized agents concerned. No human in the loop. No meeting scheduled.

5 specialized agents dispatched · 312 ms

Parallel reaction

5 specialized agents. In parallel.

Each agent accesses its own toolset — apps, browsers, MCP connectors, project documents and company knowledge — and produces a structured output. Concurrently, not sequentially.

Convergence

Outputs return. One narrative.

The 5 specialized agents return their outputs to MASTER LEGAL. It reconciles them into a single decision card.

1 reconciled decision

Validation

Handed to you. One click.

MASTER LEGAL presents the consolidated decision to you. Full evidence chain, all sources linked. Three minutes after the signal landed. One approval. One trace ID. Action executed.

Self-scheduled trigger

T+14 DAYS. The system wakes itself up.

During the parallel phase, a agent scheduled a follow-up task on its own. T+14 DAYS — without you, without a meeting, without a reminder email — MASTER LEGAL wakes itself, dispatches the right agent, and executes autonomously. You delegated the mental load.

How to sleep at night.

You're the one whose signature goes on the work. Four guarantees that hold up in front of a judge — and in front of your CFO.

Guarantee 1 · No made-up numbers

Zero hallucination on technical outputs.

If the agent uses a tool, it extracts the real number. If it can't find what it needs, it reports back — never invents. Every clause cited is traceable to source document + page + hash.

Guarantee 2 · The evidence chain

Hashed. Logged. Dispute-ready.

Every claim file ships with a SHA-256 document hash, per-action audit log (timestamp · user · model version · approval chain), and JSON export for discovery platforms. Drops straight into your firm's case management.

Guarantee 3 · Human in the loop

The AI drafts. You sign.

Vonbuild does the brute force. You hold the keys. The agent drafts the €500K claim file — but it never sends an external email. You review, adjust the tone, click Send. Your signature stands. Liability stays human.

Guarantee 4 · Tenant-resident

Your privilege boundary doesn't move.

Tenant-resident execution inside your existing Microsoft 365 or Google Workspace. Your data never trains foundation models. Attorney-work-product handling preserved end-to-end. DPA on request.

Live demo · Guarantee 3 in motion

This is what "you sign" looks like.

The €500K claim file is drafted. The opposing counsel's address is pre-filled. Then the modal blocks. Your click is the only thing that sends it. The AI prepares. Liability stays human.

Conversations

For your CFO conversation

How to justify Vonbuild to your board.

Don't tell your CFO you bought an AI tool. Tell them you bought a margin-recovery engine. Three bullet points, ready to repeat.

Bullet 1 · Cost avoidance

€50K+

per missed forfeiture

"We never miss a notification window."

Industry average: 2–3 forfeitures missed per portfolio per year, each averaging €50K+ in lost entitlement. With the always-on workforce: zero. The cost of one missed deadline exceeds an annual Company-tier subscription.

Bullet 2 · Capture rate

0.5–3%

of project value

"We file claims that were previously written off as too late or too small."

Industry pattern: typical claim capture is 0.5–3% of project value. Higher with proper prep. Workforce model compresses preparation time, raises capture rate, expands the matters per associate. A single 2% recovery on an €85M project pays for the platform for years.

Bullet 3 · Overhead

2×

matter throughput

"We get the output of a 10-person commercial team with existing headcount."

Senior associate output amplified. Same team, more matters per quarter, judgement time freed up for the work only a senior can do. The conversation moves from "we need to hire" to "we're absorbing the workload with the team we have."

Numbers are industry benchmarks (Monograph 2025, Part3 2025, claim-recovery industry consensus). Calibrated to your firm in the demo.

Start with the file you've been dreading.

Take that 500-page FIDIC contract. Or that variation file you've been postponing. Or the dispute that's been simmering for three months. Drop it into Vonbuild. See the output by lunch.
