Raising, April 2026

Contracts are one of the oldest human agreements, creating rights and obligations that both parties promise to uphold. In practice, tracking and enforcement are manual, so breaches are caught after the fact.

Contract Execution Infrastructure

Contracts make promises.
Nebula makes sure they're kept.

Nebula is the automated system that manages the contract from signature to close, enforcing obligations, protecting rights, and ensuring compliance without the admin of chasing.

The Gap

Billions have been spent on contract software.
It stops at reading.

Across every industry where two parties sign an agreement, the work of executing that agreement is still done by hand. Someone reads the document, writes down what each side owes, watches the calendar, chases the person responsible, and records whether the work was done. When a dispute arises, each side builds its own version of what happened.

Software was built to help with the first step. Sirion, Ironclad, Icertis and DocuSign have raised close to $1.5B between them. Their products read the contract and produce a list of obligations, then send alerts when deadlines approach. After that, the work returns to the humans. A list in a dashboard does not chase a late deliverable. An alert does not apply a penalty. A reminder does not prove a delivery happened. Everything that turns a contract from a document into a delivered outcome is still done by people, the same way it was done before the software existed.

Why Now

The layer does not exist yet.
The market is waking up to the fact that it should.

Across construction, commercial software, AI commerce, and public procurement, the same shift is underway in different forms. Commitments between two parties are no longer assumed to be honoured on trust. They are expected to be tracked, enforced, and proven. Every one of these forces is moving the market toward a layer that does not exist yet, and Nebula is the only party building it end to end.

2024 – 2026

Disputes are at record levels, and inadequate contract management is one of the reasons

Across a single year, disputed sums on construction projects reached US$84B globally. On the projects that went to claim, cost overruns averaged one third of the original budget and schedules slipped by sixteen months. The primary cause on the record is inadequate contract management. Industry consensus in early 2026 is that labour shortages and tighter contracts will push dispute volumes higher through the year. The cost of tracking commitments by hand is no longer theoretical. It is being measured, and it is large enough to threaten the viability of the projects themselves.

Q1 2026
Sirion Ironclad Workday DocuSign

The contract software industry is moving in Nebula's direction, and is nowhere near arriving

In the first three months of 2026, every major contract management vendor publicly committed to what they call agentic CLM. Sirion rebranded on an agentic architecture. Ironclad launched a legal-review assistant named Jurist. Workday shipped Workday CLM with a contract negotiation agent. Every announcement is in the same part of the contract: drafting, extracting, reviewing, signing. None of them touch what happens after the signature. None of them enforce a deadline, prove a delivery, or build a reputation that follows a party across projects. The industry is signalling, in public, that the post-signature layer is where the next value sits. Nebula has been building it for two years, holds twelve patent families across every part of it, and is the only company that starts at enforcement instead of racing toward it.

April 2026

The contract framework itself is breaking under AI agents

In early April, Morgan Lewis published that the software-as-a-service contract framework is no longer adequate for agentic AI, because the assumption that a human stands between the system and every consequential decision has collapsed. Gartner is forecasting that by 2028, ninety percent of business-to-business buying will be intermediated by AI agents, moving more than fifteen trillion dollars a year through agent-to-agent exchanges. When an agent signs on behalf of a company, there is no human on either side to chase a late deliverable or to claim a right before it lapses. The enforcement has to live in the system, or it does not happen at all. No incumbent has started building this. Nebula already is.

Feb – April 2026

Verified delivery is becoming the procurement standard

The United States Department of Defense released version 4.1.4 of its Supplier Performance Risk System in March, and added Vendor Threat Mitigation procedures to its instructions in February. The European Commission published model contractual clauses for the EU Data Act in April. Commercial procurement research for 2026 names persistent verified performance data as the defining shift, replacing questionnaires and self-reported slogans. Pre-qualification is moving from paperwork on file to performance in the field. Someone has to generate that proof at the contract level, across every party, in a form that travels between buyers and auditors. Nebula's Verify and Certify engines were designed for this moment.

Four forces. One missing layer. Every force in this section is pushing the market toward infrastructure that does not exist yet, and the companies large enough to build it are still busy catching up to the previous era. Nebula is the only party running at the layer directly. The capital raised in this round is what turns a category-defining head start into an unassailable position before the incumbents finish turning their ships.

The Nebula System

Seven engines.
One loop.

Each engine automates a step that the two parties to a contract currently run by hand. Together they carry the agreement from signature all the way to a portable delivery reputation, the verified record of how each party honoured what they signed, which then travels with them to every future agreement the way a credit history travels with a borrower. Along the way, every action taken is cryptographically anchored. Cryptographic anchoring is a mathematical seal placed on each entry at the moment it is made, so that years later the record is provably the same record that existed at the time, and neither side can rewrite it.

01 / WHERE YOU START

Extract

Upload a contract. AI reads every obligation and every right from the natural language of the document. What each party owes, what each party is entitled to claim, the deadline, the clause reference, the consequence. No counterparty required to get started.

Replaces: reading the contract by hand and typing every clause into a spreadsheet.

94%
Accuracy
02

Accept

Nebula presents the full register to both parties. Either side can propose adjustments, raise concerns, or push back on a clause before anything is locked. When both parties have mutually agreed, the register becomes the single shared source of truth, timestamped and binding. Neither side can later claim a different version.

Replaces: email chains, redlining, and weekly status meetings held to agree on what was already agreed.

Differentiator
03

Enforce

From the locked register, Nebula generates self-executing rules that run continuously on a 15-minute cycle. When an obligation slips its deadline, the consequence fires automatically. When a condition is met, the dependent right becomes exercisable on the spot. Everything runs as agreed, without anyone having to remember, chase, or escalate.

Replaces: humans chasing status, applying penalties by hand, and losing entitlements because nobody noticed the trigger.

Only Nebula
04

Adapt

When a delay is genuine and both parties agree, the register adjusts automatically. The contractor's right to claim time is preserved without a dispute. The client's right to challenge is not silently surrendered either. Anti-gaming checks sit over the top: Nebula detects collusion between parties, backdating of pardons, reciprocal rubber-stamping, and sudden changes in patterns that do not match the project's history. Flexibility is real, but it cannot be abused.

Replaces: contested variations, manufactured excuses, and extension-of-time disputes that consume months of both sides' attention.

Only Nebula
05

Prove

Every obligation fulfilled and every right exercised is recorded the moment it happens and cryptographically anchored. The record is immutable. Months or years later, what both parties see is provably the same record that existed at the time.

Replaces: both parties producing their own version of events when a dispute arrives, and lawyers reconstructing the timeline from email archives.

Only Nebula
06

Verify

A running score built from the verified record of how a party has honoured its obligations and respected the counterparty's rights across real agreements. The score follows the party from one project to the next, portable the way a credit file is portable. Like a credit score, but for whether you keep the agreements you sign.

Replaces: a delivery record that disappears the moment the project closes and has to be rebuilt from references on the next tender.

Only Nebula
07

Certify

Certify is the formal rating of each party in Nebula, earned from their verified record across every agreement the platform has seen. It is the answer, on-platform, to the question every counterparty asks before signing: have they delivered in the past. The rating stands on its own. Its use in procurement, insurance, and lending is what it enables downstream, not what it is.

Replaces: pre-qualification checks that verify paperwork on file, not performance in the field.

Only Nebula

Across twelve weeks on a live project, Nebula tracked 347 commitments between a contractor and its counterparty. Thirty-eight were heading for breach. Nebula surfaced every one of them before the deadline. On most projects, a breach like this is not noticed until weeks after it has happened, when the counterparty raises a claim or an invoice arrives with numbers nobody recognises.

By then, the cost is already set. What could have been a phone call is a legal letter. What could have been a variation settled in a meeting is a dispute that takes months to close. What could have been a right exercised in time is a right that has quietly been lost.

The manual version of this work takes hours every week and still misses what matters. When the project closes, the file disappears into a folder nobody will open again. Nebula runs the same work continuously, catches the things that would otherwise be missed, and leaves behind a record that follows both parties into every agreement they sign next.

Start with one contract. Upload it. See every obligation and every right in one place, before the first meeting. No counterparty required.

The Moat

You cannot encode a process
the industry has never automated.

A funded team can build a contract-reading model in six months. They cannot encode what the industry has learned over decades of running live agreements by hand. Every design decision inside Nebula is drawn from the practice the industry has already worked out on real projects: how an obligation is classified, when a consequence should fire and when it should pause, what counts as a valid confirmation of delivery, how a right is preserved when a delay is genuine. Nebula is the first system to translate that practice into software. The rules exist. From here, every new agreement that runs through the system sharpens them further.

Embedded Practice

Decades of accumulated industry practice on how live agreements are actually run, translated into the rules the system runs on. A new entrant does not start with a blank model. They start behind the entire industry.

Data Gravity

Every agreement that runs through Nebula sharpens the rules, deepens the proof ledger, and extends the reputation record. A competitor starting today begins with zero historical data. The history is the asset, and it compounds every month.

Patent Stack

Twelve patent families cover every layer of the system: extraction, enforcement, adaptation, proof anchoring, reputation scoring, and certification. Any team that wants to build this territory encounters Nebula's filings first.

Reputation Lock-in

A verified record of how a party has honoured its agreements follows them from one project to the next. Leaving Nebula means leaving that record behind. The cost of switching grows every time the party signs something and keeps it.

Day One

Upload a contract. Know what you owe. Claim what you're owed.

Before any counterparty joins. Before compliance starts. On day one, you upload a contract and Nebula gives you the full register: every obligation you carry and every right you can claim, with clause reference, deadline, responsible party, and consequence of breach. Most parties have never seen the full picture. Nebula surfaces it before the first meeting.

The Difference

Enforcement is usually one-sided.
Nebula is the first system fair to both.

Every contract system built until now has been something one party deploys against the other. The principal watches the contractor. The buyer watches the supplier. The client watches the consultant. The reader of this site has probably been on the wrong end of one. The register gets used as a liability list, the record gets written by the stronger party, and the weaker party signs up to a system whose job is to catch them out. Nebula is the first system that writes the record from both sides of the agreement at once. It sees when a party delivered on time, when they absorbed a delay caused by the other side without complaint, and when they honoured an obligation the other side had already forgotten. The same system that catches a breach also catches the professionalism that goes unrewarded everywhere else.

Both sides agree to Nebula because Nebula is the first record that can clear them, not just convict them. A Nebula score is proof of professionalism, not a liability register.

Intellectual Property

The Ask

A head start this cheap does not come twice.
$380K to hold the layer before the industry catches up.

Nebula is the only company building contract execution infrastructure. The incumbent contract software industry has publicly committed, in the last three months, to racing toward the same layer, and has not arrived. Twelve patent families sit across every part of the territory they are walking into. The eighteen months this raise funds are the months where a category-defining head start becomes an unassailable position.

We enter through construction, because construction is where the cost of bad contract execution is already measured. An $84B-a-year dispute industry is the proving ground. Once the engines are running on live projects at scale, the same architecture carries into energy, government, defence, professional services, and every other industry where two parties sign an agreement and need it to work. The entry is one vertical. The market is every contract.

Founder full-time

Nebula has been built to its current state alongside a full-time engineering role. On close, that ends. The founder goes full-time on Nebula the day the SAFE closes, and stays there.

Convert the eleven Australian provisionals into full international filings before the priority window closes. The patent stack is the defensive geography that makes the territory expensive to contest.

The incumbents are turning their ships. This round is what arrives at the layer before they do.

Vision

Every agreement in the world
runs on the same rails.

If Nebula works, the infrastructure for running a contract becomes as standard as the infrastructure for sending a payment. Every commitment between two parties, in any industry, in any jurisdiction, sits on a system that reads the agreement, enforces the deadlines, records the proof, builds the reputation, and carries it into the next deal. The question a buyer asks before signing is no longer "do I trust this supplier". It is "show me their Nebula record".

Reputation becomes a portable asset the way credit became a portable asset a century ago. A party with a verified record of honouring its agreements moves through the market faster, borrows cheaper, insures lower, and wins more work. A party without one is the one asking for the meeting. The cost of keeping a promise falls. The cost of breaking one rises. Commerce runs at the speed of verified trust.

Payment rails moved money. Nebula moves the record of what was actually done.
