## Glean

Glean addresses a problem most enterprises hit after their first wave of AI adoption: models are powerful but isolated from the context of the business. The platform builds an enterprise context layer by indexing and understanding content across the tools a company already runs on, then uses that grounding to improve both answer quality and efficiency. Because fewer irrelevant tokens need to be sent to a model, the same question costs less to serve.

The product surface spans four areas: enterprise search, an AI assistant for everyday work, an agent platform for automating long-running processes, and Glean Protect for security and governance. Administrators also get model routing and an AI gateway, letting them decide which models handle which requests without rebuilding integrations. Everything inherits the access permissions of the source systems, so answers stay within each employee's existing rights.

Glean serves large organisations across finance, healthcare, retail, technology, and government, with published customers including Booking.com, Zillow, and Ericsson. It holds SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR, and TX-RAMP Level 2 attestations, and reports 275+ connectors, 40+ supported language models, and 99.9%+ uptime on core services.

**Pricing & Plans:** Contact for pricing. Glean is licensed to organisations based on seats, connectors, and deployment scope, and is evaluated through a demo rather than self-serve purchase.

- **Permission-aware enterprise search:** Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
- **Agent builder and orchestration:** Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
- **Model routing and AI gateway:** Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
- **Grounded content and analysis:** Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.
- **Governance and observability:** Administrators get usage controls, spend visibility, audit logging, and compliance-ready governance for every AI interaction.

**Strengths:** Answers cite source systems and inherit their permissions, which removes the main blocker to enterprise-wide rollout; One platform covers search, assistant, and agents instead of three separate vendors; Model routing and token efficiency directly reduce the cost per AI query at scale; 275+ pre-built connectors shorten integration work considerably

**Limitations:** Enterprise pricing is quote-based, so budget planning requires a sales conversation; Full value depends on connecting many internal data sources, which takes IT effort; Smallest teams may find the platform more than they need

## Spike

Spike reimagines email as a chat-style feed instead of a stack of threads. You can connect an existing Gmail, Microsoft, or other account and use Spike as your daily client, or create a new business email on a custom domain hosted by Spike. Conversations group by person, attachments and files appear in one place, and a unified inbox pulls every account into a single view so you stop jumping between apps.

AI is woven through the experience. Smart sorting surfaces important messages first, AI summaries give instant snapshots of unread mail and long threads, and contextual drafting helps you compose quick replies or brainstorm with AI in your own voice. Built-in translation handles messages you receive or write, and natural-language search helps you find emails and files fast.

For teams, Spike adds shared inboxes for customer email, channels and groups for discussion, collaborative docs and notes, tasks that live inside the inbox, and one-click audio or video meetings. Non-Spike recipients still receive a normal email, so external contacts need no special setup. A free tier is available alongside paid plans, and the company also promotes iGPT, an email intelligence API that powers AI agents and automations with email context.

**Pricing & Plans:** Offers a free plan plus paid tiers; exact pricing and per-seat limits for teams change over time, so check the official pricing page for current numbers.

- **AI summaries and smart sorting:** AI snapshots unread mail and long conversations so you can catch up in seconds, while priority inbox surfaces the messages that matter first.
- **Context-aware AI drafting:** Draft quick replies, contextual responses, and brainstormed messages with AI assistance directly inside the composer.
- **Conversational email and unified inbox:** Threads are grouped by person like a messenger app, and every connected account lands in one inbox with file management and powerful search.
- **Team collaboration tools:** Shared inboxes, channels and groups, collaborative docs and notes, tasks, and one-click audio and video meetings all live inside your mail workspace.
- **Works with your existing email:** Use Spike with an existing Gmail or Microsoft account, or create a business email on a custom domain with Spike's email hosting.

**Strengths:** Conversational, chat-like interface makes long email threads easier to follow; AI summaries and drafting cut time spent catching up and replying; Consolidates mail, chat, docs, tasks, and meetings into one workspace; External recipients still get standard email, so no one else has to switch

**Limitations:** Best experience requires adopting Spike as your primary mail client; Advanced team features sit behind paid tiers, so costs scale with seats; Feature breadth can feel overwhelming for users who only want a simple inbox
