Nimbus Marlowe vs Clio Grow: Which Fits a PI Firm?

Clio Grow and Nimbus Marlowe both help law firms turn prospects into clients, but they solve different halves of the problem. Clio Grow is the intake and client relationship manager in the Clio ecosystem. It organizes leads, sends intake forms, and moves prospects through a pipeline, and Clio now sells AI phone, web, and email agents for Grow, billed per matter hired. Nimbus Marlowe is the AI operations layer for personal-injury law firms, starting with intake. It answers the phone. An AI intake coordinator picks up every call 24/7 by voice, qualifies the caller, and books the consult, so the lead never has to find a form or wait for a callback.

For a solo or small personal-injury firm, that difference decides whether a 9pm car-accident call becomes a signed case or a voicemail the caller never leaves.

What is Clio Grow?

Clio Grow is the intake and CRM half of Clio's product line. It gives firms online intake forms, a lead pipeline, scheduling links, e-signature, and automated follow-up email. It connects to Clio Manage, Clio's case-management system, so a qualified lead can flow into a matter. Grow is included in Clio's Elite plan and sold as an add-on for the Core and Signature plans, which start at $49 per user per month. Clio Grow is built for general legal practice across many practice areas, not specifically for personal injury.

Clio's pricing page now lists AI phone, web, and email agents for Grow, billed per matter hired with Grow AI's help. Firms that want a person on the line can add a receptionist service through an integration such as Smith.ai or CallRail, on a separate bill. Ask Clio for the per-matter rate before you compare the two.

What is Nimbus Marlowe?

Nimbus Marlowe is the AI operations layer for personal-injury law firms, starting with intake. Instead of waiting for a prospect to find a form, the Nimbus intake coordinator answers every inbound call 24/7 by voice, asks the qualifying questions a PI firm needs, and books the consultation on the calendar. From there the same layer extends into case preparation, contract and document review, demand letter drafting, and collections follow-up. The research assistant sits alongside those roles, giving your team in-app research and drafting help on a live matter; it is included with the app rather than billed per completed unit.

Nimbus sits in front of your existing practice-management system. It does not replace Clio, Filevine, or whatever you already use to run matters. It handles the front door, the part where speed decides who signs the client, and hands clean, qualified intake into the system you already trust.

Every output is a draft a licensed attorney reviews and adopts. The intake coordinator qualifies and books; it does not give legal advice or decide the merits of a claim. Where a potential conflict shows up, the system flags it and the attorney reviews and decides.

Why speed matters for personal-injury firms

Personal-injury work runs on contingency. A missed lead is not a smaller invoice, it is the entire fee walking to the next firm on the search results.

The numbers are stark. 39% of calls to law firms go to voicemail, and over half of firms never return a voicemail within 72 hours (Clio Legal Trends Report ghost-shopper study). Meanwhile, responding in 5 minutes instead of 30 makes you 21x more likely to qualify the lead (Lead Response Management study).

A CRM helps you organize the leads you already caught. At 9pm the question is whether anything answers the phone when no one is at the desk. Both products now say theirs does, so compare how each one charges and what it covers after the call ends.

Pricing: per user vs per completed unit

Clio Grow sits inside Clio's per-user plans, which start at $49 per user per month, and its AI agents are billed per matter hired.

Nimbus prices differently. The CRM is free and never invoiced. You pay flat, published rates per completed unit of work: qualified intake around $18, contract review $65, case preparation $95, a demand letter draft $170, and collections follow-up at a flat per-unit rate. No seats, no quotes, and never a percentage of any recovery, settlement, or judgment. For firms that want volume discounts there is a committed option with lower rates and a $500 per month floor realized as a true-up, nothing prepaid and nothing that expires.

Put it against the alternative: a full-time intake specialist runs $3,000 to $4,000 per month before benefits. Nimbus charges only for completed work, and the CRM costs nothing.

Which one fits your firm?

Choose Clio Grow if you are already committed to the Clio ecosystem and want intake inside the same system that runs your matters.

Choose Nimbus Marlowe if you are a solo or small personal-injury firm, missed after-hours calls are costing you cases, and you want the phone answered and the lead qualified before a competitor gets there. Many firms keep their existing CRM and put Nimbus in front of it for the intake layer.
