The best company brain software for agencies and consulting firms depends on who needs to use the brain. If only your team will query it, an internal tool like Glean or Claude Projects can work. Keyword being "can". If you want your clients to use your firm's expertise between calls, Gia (getgia.ai) is built for that: a company brain for agencies and consulting firms that they deploy to their own clients, white-labeled, through Slack, Microsoft Teams, browser or MCP (directly in their own Claude or GPT so they can ask your firm's AI").
A company brain is one living system that holds what your firm knows: playbooks, SOPs, call notes, Slack threads, CRM history, and the reasoning behind past decisions. Generic AI tools already know everything public. What they've never seen is how your firm diagnoses a problem, which is the part clients pay you for.
Most "best company brain" lists, including the well-researched comparison of 10 company brain architectures from Slite, judge tools on how well they serve employees. That's the right test for a software company. For an agency or consultancy, the client is the second user, and that changes the ranking.
Other tools build an internal knowledge base or a public chatbot. Gia builds a private brain the firm hands to its clients as a paid product.
Every tool below was checked against its own site in November 2026. "Not listed" means the site didn't say, so treat it as unconfirmed rather than missing.

Gia connects to the tools your firm already runs on (Slack, Google Drive, SharePoint, your CRM, call recordings) and builds a brain from them: SOPs, decisions and the evidence behind them, client wins and pitfalls. From there you create a workspace per client and pick exactly which folders and sources it can see, so one client never reaches another client's data or your internal files.
Clients reach it where they already work. That might be a white-labeled Slack bot in their workspace, Microsoft Teams, a browser extension that answers inside a Google Doc or HubSpot, a branded portal on your own site, or an MCP connector so their team can use your expertise inside Claude or ChatGPT. If you want the background on that last one, I wrote about why every firm will need an MCP.
Gia lists SOC 2 Type II, per-client isolation and role-based access, and client data is never used to train models. When the brain doesn't know an answer, or a question touches pricing or scope, it hands off to a human. Setup takes about a day, and a native Stripe integration lets you charge clients monthly or by usage.
The weak spot is that Gia is newer than most tools on this list, and it doesn't publish prices. If you only need an internal search tool, you'd be paying for client features you won't use.
Glean is an enterprise AI platform with 275+ connectors, an assistant, and an agent builder, aimed at departments from engineering to legal. It's strong at helping employees find things across a big company. Its site doesn't mention deploying to outside clients or white-labeling, and pricing is by demo. For a 15-person agency it's usually more platform than you need, pointed at the wrong user.
A lot of the agency owners I talk to already run one Claude Project per client with brand guidelines, tone of voice, and past work loaded in. It's a fine way to start. Per Anthropic's help article on Projects, sharing is limited to members of your own Team or Enterprise organization. So the brain stays inside your firm, you upload files by hand, and there's no way to brand it or bill a client for it.
Chatbase builds AI support agents across chat, email and voice, with integrations like Zendesk, HubSpot and Intercom on paid tiers. It's good at answering a business's customers. According to Chatbase's pricing page, removing its branding is a $99/month add-on and full white-labeling sits on Enterprise. It's built around a public-facing bot rather than a private brain per client.
CustomGPT.ai turns websites, PDFs and videos into agents that cite sources and try hard not to make things up. Slack is on every plan, and branding removal starts at Premium. It works well for a knowledge base anyone can query. It doesn't list per-client workspaces or a way to charge clients.
DocsBot trains chatbots on docs and help desk tickets, with a free tier and an MCP server from the Standard plan. Unbranded widgets and per-bot roles for reselling come on the Business plan. It's a solid support tool and a lighter fit for sharing judgment as opposed to documentation.
Stammer is built for AI agencies that sell chat and voice agents to businesses: lead capture, appointment booking, call handling. White-labeling and client dashboards come on the $99/month plan, and you set your own prices. The agents mostly serve your client's customers. That's different from giving the client a brain that holds your firm's expertise.
Pickaxe lets you build prompt-based agents and sell them through Studios with Stripe subscriptions, white-labeled on every plan. If your offer is one sharp tool, like a proposal grader or an audit form, it's quick to ship. It doesn't build a brain from your firm's calls, Slack and CRM, so you're writing and maintaining each tool's knowledge yourself.
Delphi builds a digital version of one person from their podcasts, writing and videos. It's a good fit for a creator or a single expert. Its site describes a personal clone and doesn't mention a firm-wide option, so for a consultancy that wants the whole team's thinking in one place, it covers the founder and nobody else.
Start with one question: will a client ever log in? If not, pick the internal tool your team will actually open. If yes, check four things.
Then start small. My advice to every firm I onboard is to pick one named client and one use case, test the brain with questions that client has actually asked you in Slack or email, and expand once it's answering well. Firms that try to roll it out to every client at once stall for weeks on trust.
This is the objection I hear most, and it's fair. My answer is that the brain handles the "how do I" questions at 11pm and between sessions, and your calendar stays for the judgment calls and taste you can't productize. It works alongside your team. A HubSpot implementation firm we work with leaves a brain with clients after the project so they can ask why the forecast was built a certain way, and the firm stays the first call when something bigger comes up.
Firms I talk to package it three ways: a lower-priced self-serve tier for clients who can't afford the full retainer, a premium bundle on top of the retainer, or a leave-behind subscription for clients who finish a project or pause. I go deeper on the pricing side in how to monetize client-facing AI and how to productize agency services.
It's a single AI system trained on your agency's own knowledge: SOPs, call notes, Slack, CRM history, and past decisions. Your team uses it to answer questions the founder used to answer. A client-facing company brain goes one step further and lets clients query a scoped, private version of that knowledge.
Glean is a company brain for large enterprises and their employees. Its site doesn't mention deploying to outside clients or white-labeling, which is what most agencies and consulting firms need once clients are involved.
Claude's own documentation describes sharing Projects only with members of your Team or Enterprise organization. If you want clients to use your expertise inside Claude, an MCP connector from a tool like Gia is the usual route.
For a private brain per client that carries your brand and can be billed, Gia is built for that use. Stammer AI and Pickaxe also white-label, but they're designed around chat and voice agents or single sellable tools, not a brain built from your firm's history.
Look for per-client workspaces where you choose which folders and sources each one can see, plus role-based access and audit logs. In Gia, each client brain is isolated from the others and from your internal files.
Public prices on this list run from free tiers to several hundred dollars a month, with enterprise plans quoted on request. Glean, Gia and Delphi don't publish prices. With a client-facing brain, the better question is what you'll charge for it, since many firms price access as its own subscription.
Already working with a few B2B marketing agencies on this. If you run an agency or consultancy and want your clients using your expertise between calls, book a 30-minute demo and I'll show you what one client's brain would look like with your own material.
