Glean is enterprise search with an AI layer on top. FellowHire is a team of role-specific AI fellows that take action inside Slack and Teams. Different jobs. Here is the honest comparison.
You want AI that does the work — drafts the proposal, qualifies the lead, updates the CRM, writes the brief. You need a specialist for one role, living inside Slack or Teams, with deep tool access.
You are a large enterprise where finding information across many tools is the bottleneck. You have thousands of employees and millions of documents. You want one search bar over everything.
You are big enough that company-wide search is a real problem AND you want fellows doing role-specific work. They do not overlap. Glean indexes; fellows act.
| Capability | FellowHire | Glean |
|---|---|---|
| Primary job | Do the work | Find the answer |
| Where it lives | Inside Slack and Microsoft Teams | Web app, browser extension, Slack/Teams plugin, mobile |
| Output | Drafted emails, updated CRM records, completed tasks, PDFs | Search results, summarized answers, citations |
| Specialization | Custom-built per role (Sales, Paralegal, Support, etc.) | One generalist search assistant across all your tools |
| Best fit team size | Small to mid-market teams that need work done | Mid-market to enterprise — typically 500+ employees |
| Setup time | About a week to build a fellow | Weeks to months (connectors, permissioning, indexing) |
| Pricing | Predictable annual per fellow | Per-seat enterprise pricing; sales-led |
| Self-serve signup | Paid pilot scoped over a call | Sales-led, contract-driven |
| Action capability | High — fellows execute multi-step workflows in your tools | Low — Glean Agents emerging but core product is retrieval |
| Knowledge depth | Trained on your role-specific playbook, ICP, tone, processes | Indexes everything you connect; depth comes from your documents |
| Tool integrations | Deep, role-specific (CRM, ticketing, legal, etc.) | Broad connector library across enterprise SaaS |
| Permissioning model | Fellow operates with scoped credentials per task | Inherits permissions from connected systems (key strength) |
| Security posture | Pilot-stage; SOC 2 roadmap | SOC 2 Type 2, ISO 27001, enterprise-grade |
| Whole team usage | Yes — anyone in Slack can ping the fellow | Yes — every employee gets a seat |
| Customization | Fellow is custom-built per customer | Configuration over connectors and prompts; not custom-built |
| Best for | Teams that want a junior specialist, hired and trained | Enterprises drowning in their own documents |

Glean's job is to surface the right answer from across your tools. FellowHire's job is to take the action that follows the answer. A Sales fellow does not just find the prospect's last reply; it drafts the follow-up, updates the CRM, and schedules the meeting. Different problem, different bet.
This is not a subtle distinction. Search-first AI assumes the bottleneck is finding information. Action-first AI assumes the bottleneck is doing the work. For teams where the answer is already obvious but nobody has time to act on it, action-first wins. For enterprises where the answer is buried across a hundred systems, search-first wins.
Glean is built for the enterprise where information sprawl is the headline pain. FellowHire is built for the small or mid-market team where the headline pain is 'we need another junior on this role and cannot hire one'. The buyer profile is different. So is the price tag.
If your company has thousands of employees generating documents across dozens of tools, the retrieval problem is real and Glean solves it well. If your company has 20 to 200 people and the problem is that your sales team cannot keep up, your support queue is growing, or your paralegals are buried — a fellow is a more direct answer.
Glean takes time to deploy because indexing and permissioning across an enterprise is genuinely hard. Connecting dozens of data sources, respecting per-user access controls, and building a reliable search index over millions of documents is serious infrastructure work. Weeks to months is normal.
FellowHire takes about a week because we are building one fellow for one role on the tools that role uses. Faster start, narrower scope. You are not boiling the ocean — you are solving one role's workflow problem and putting a specialist in Slack to handle it.
Enterprise-wide retrieval, mature security and compliance posture, permissioning fidelity across hundreds of connected systems, the ability to serve 10,000-employee organizations. If that is your problem, Glean is a strong choice and we will tell you so.
Glean's permission model — inheriting access controls from every connected system — is a genuine technical achievement and a key strength for regulated enterprises. Their SOC 2 Type 2 and ISO 27001 certifications matter for procurement teams. We are honest about where we are on that journey.
Taking action on a defined role, predictable annual pricing without per-seat math, depth on a single role versus breadth across all of them, fitting inside an under-100-person company without an enterprise sales cycle.
A FellowHire fellow does the work. It drafts the proposal, qualifies the lead, triages the ticket, reviews the contract. It does not find the answer and hand it to you — it acts. For teams where the bottleneck is execution, not information retrieval, that is a fundamentally different product.
Not really. Glean answers questions; fellows do work. Buyers sometimes evaluate them in the same shopping trip because both get filed under 'AI for work', but the jobs are different. Some teams will end up using both.
A fellow can read from the tools it is connected to and pull what it needs to do its job. It is not a company-wide search engine. If 'find anything anyone in the company has ever written' is your problem, Glean is the right tool for that.
Glean has been moving toward agents and actions, but the core product is retrieval. Fellows are built action-first. If your buyer pain is 'we need the work done', the action-first product is a closer fit.
Glean is enterprise per-seat pricing, typically negotiated. FellowHire is annual per fellow. A 1,000-person Glean deployment is a different financial decision than hiring three FellowHire fellows for three roles.
Probably FellowHire, honestly. Glean's value compounds at scale; at 50 people, the indexing problem is usually solvable with better Slack search and tighter Notion habits. A specialist fellow gives you a clearer ROI.
Tell us the role. We'll scope the fellow.
