Upfront, Predictable Pricing

Arceus eliminates the uncertainty of billable hours by providing a flat fee for every engagement before any work begins. Clients receive a clear, fixed price quote in under 60 seconds, and that quote is the final price. There are no hourly tracking, no surprise invoices, and no hidden costs. This pricing model allows fast-growing companies to budget for legal expenses with confidence and focus on closing deals rather than monitoring legal costs. The commitment to transparency extends to the guarantee: if Arceus misses its promised deadline, the service is provided at no charge.

Fast, Guaranteed Turnarounds

Speed is a core tenet of the Arceus model. The firm leverages AI-assisted workflows and dedicated attorney teams to deliver contract reviews in hours, with a median turnaround time of just 8 hours. For urgent matters, rush options are available to ensure that time-sensitive deals do not stall. This rapid pace is made possible by a streamlined process that eliminates traditional bottlenecks like intake forms and introductory calls. Clients can simply send a contract and receive expert redlines and feedback within the same business day, enabling them to maintain momentum in negotiations.

Collaborative Review Workspace

Arceus provides a centralized, shared thread for every contract engagement. Clients, their internal teams, and the assigned Arceus attorneys can comment, redline, and make decisions in one place. This eliminates the chaos of forwarded email chains, version control issues, and disjointed communication. The workspace is designed for clarity and efficiency, allowing stakeholders to track changes, ask questions, and approve revisions in real time. This collaborative approach ensures that everyone stays aligned and that the contract moves forward without confusion or delays.

Comprehensive Negotiation Support

Arceus does not stop at initial review. The firm stays at the negotiating table through every round of redlines and counterpositions until the contract is fully executed. Clients receive ongoing support to navigate complex negotiations, respond to opposing counsel, and secure favorable terms. This end-to-end service ensures that fast-growing companies have consistent legal backing from the moment a contract is submitted to the moment it is signed. The combination of AI efficiency and human attorney expertise allows Arceus to handle the full lifecycle of commercial agreements with precision and responsiveness.

Accelerating Customer Contract Closures

Sales teams at fast-growing companies often face delays when customer contracts require legal review. Arceus streamlines this process by reviewing and redlining customer agreements, MSAs, and SOWs within hours. The upfront pricing allows sales leaders to predict costs, while the fast turnaround prevents deals from cooling off. With Arceus, companies can shorten their sales cycle, reduce friction with prospects, and close more revenue-generating contracts without sacrificing legal quality or risk management.

Streamlining Vendor and Supplier Agreements

Managing a growing roster of vendors involves reviewing numerous NDAs, DPAs, and service agreements. Arceus handles this volume efficiently by providing quick, consistent reviews across all vendor contracts. The collaborative workspace allows procurement teams to share context and negotiate terms directly with Arceus attorneys. This use case is particularly valuable for companies scaling their operations, as it ensures that vendor relationships are established on solid legal footing without creating a backlog that slows down business operations.

Supporting Fundraising and Corporate Transactions

When a company is raising capital, issuing term sheets, or negotiating employment offers, speed and accuracy are critical. Arceus provides dedicated support for these high-stakes documents, delivering expert review and drafting in hours rather than weeks. The upfront pricing model gives founders and CFOs certainty over legal costs during a period of significant financial activity. By handling the legal intricacies of fundraising and corporate transactions, Arceus allows company leadership to focus on investor relations and strategic decisions.

Managing Contract Renewals and Amendments

Existing contracts often require periodic review, renewal, or amendment. Arceus simplifies this ongoing legal work by providing a repeatable, fast process for handling modifications to current agreements. Clients can send renewal terms or amendment requests and receive updated redlines with clear explanations of changes. This use case ensures that companies maintain compliant, up-to-date contracts with customers and vendors without dedicating internal legal resources to routine administrative tasks. The predictable pricing makes it easy to budget for recurring legal needs.

How does Arceus guarantee its turnaround time?

Arceus commits to delivering contract review within the agreed-upon timeframe, which is typically measured in hours. If the firm fails to meet that deadline for any reason, the service is provided free of charge to the client. This guarantee is a core part of the value proposition and reflects the confidence Arceus has in its AI-powered workflows and attorney team. Clients receive a clear deadline at the outset, and the platform tracks progress to ensure accountability.

What types of contracts does Arceus handle?

Arceus covers a wide range of commercial contracts that fast-growing companies encounter regularly. This includes NDAs, MSAs, SOWs, vendor agreements, customer contracts, DPAs, term sheets, employment offers, renewals, and amendments. The firm is designed to handle both routine agreements and complex, high-value deals that define a company's quarter. If a contract type is not listed, clients can inquire, as the firm's AI-native approach allows for flexibility across many commercial legal documents.

Is Arceus a replacement for a general counsel or in-house legal team?

Arceus is designed to complement and extend the capabilities of a company's existing legal function, not necessarily replace it. For early-stage startups without in-house counsel, Arceus serves as a primary legal resource for contract work. For more established companies with a legal department, Arceus acts as an on-demand, scalable partner that handles overflow work, accelerates turnaround times, and provides cost certainty. The service is particularly valuable for high-volume contract tasks that would otherwise create bottlenecks.

How does the pricing work if a contract requires multiple rounds of negotiation?

Arceus provides upfront pricing for the entire engagement, which includes support through multiple rounds of redlines and counterpositions until the contract is signed. The flat fee quoted at the start covers the full lifecycle of that specific contract review and negotiation. There are no additional hourly charges for subsequent rounds of revisions or for extended negotiation periods. This approach ensures that clients know the total cost from the beginning and can proceed with negotiations without worrying about escalating legal fees.
