Contracts are submitted via Slack, AI agents gather context and prep work, a licensed attorney reviews everything, and pricing is quoted upfront (around $500 per contract). Founders and AI commentators on social media praised the turnaround time (3-6 hours versus days) and claimed 70%+ savings versus traditional firms, with commercial-contract spend reportedly growing from $15K to $500K across funding rounds. Most of the enthusiasm and figures come from the company itself and its founder-fan base, with open questions about whether the human-sign-off model scales and how incumbent firms will respond. ## Content The pitch from the startup crowd is blunt: legal is the last department still running on email and dread, and Arceus is the fix. The company launched an AI-plus-attorney law firm for commercial contracts and, per @rohanpaul_ai, raised $17M to do it. The mechanics are simple. You drop a contract into Slack. AI agents gather business context and speed up the grunt work. A licensed attorney reviews everything and stays responsible for it. You approve a flat price before anything starts. Arceus says it handles review, redlines, drafting and negotiation of MSAs, DPAs, NDAs, order forms and vendor agreements. ## The founder horror-story chorus @kloss_xyz set the tone: "almost every founder I know has a law firm horror story." The old way, in his telling, is email only, no price until the invoice, "we'll circle back Monday," and a five-figure bill. The new way is a Slack message, $500 flat per contract quoted upfront, and an answer in hours. @trikcode went further: "we have automated code, emails and design," yet legal "still takes 5 days and on top bills you more for being slow." Their number for Arceus is 4 to 6 hours. @omarsar0 puts contract reviews at 3 to 5 hours on average. Nobody is quite agreeing on the clock, but everyone agrees it beats days. ## The business-model angle The sharper take is about incentives. @rohanpaul_ai points out that law firms sell time, so software that saves time eats directly into revenue. A flat fee quoted up front removes the incentive to let a review run long. He relays Arceus's claim that customers cut legal spend by 70% or more versus traditional firms. That is the company's number, not an independent one. He also notes that commercial contracts are the fastest-growing category, with annual spend rising from $15K-$60K at Series A to $150K-$500K at Series D. ## The bigger bet @omarsar0 sees a pattern: "I expect more AI companies to run the service themselves and sell the outcome." Not software you license, but the work, delivered. @svpino calls it inevitable that AI and real, licensed attorneys would team up, and stresses the part that matters for trust: the same human attorney remains responsible for the work. That last detail is what separates this from a chatbot with a legal disclaimer. The AI does the prep. A person with a license signs off. ## Questions this post answers ### How much does Arceus charge for a contract review compared to traditional law firms?
