Gatekeeper

What it is

Gatekeeper is a vendor and contract lifecycle management (VCLM) platform built for the buy side: the contracts, renewals, compliance documents, and risk records that come with suppliers, not the paper your sales team sends to customers. It is London-based and has been backed by Vista Equity Partners since a growth investment from Vista’s Endeavor Fund announced on 17 October 2023. The vendor pitches it as the only platform that handles third-party compliance, contracting, and spend together. Whatever you make of “only”, the pitch describes the product shape accurately: a contract repository, a supplier record, a workflow board, and a third-party portal sharing one data model.

The 2026 release notes set the current buying case. In February, any workflow phase could be paired with an AI agent that posts a briefing note, with human sign-off still required. In April, agents gained Form Update: they write values into workflow form fields, such as pulling company details from a vendor registration document, with every value logged in the card history. July added Gatekeeper Chat on all plans, a Word add-in that drafts tracked changes, and a Claude connector over MCP that reads contract metadata and, where permitted, creates workflow cards. On 19 September 2026 the LuminIQ and Lumin AI brands were retired in favour of plain “Gatekeeper Agents”, “Gatekeeper Chat”, “Extract”, and “Enrich”. The rename changed nothing functional, so read older reviews that mention LuminIQ as the same product.

Why it shows up in Legal Ops stacks

• Supplier-first data model. A vendor is a first-class record with its own documents, risk scores, scorecards, and spend, and contracts hang off it. Sales-side CLMs treat the counterparty as a field on a contract. When the question is “which suppliers renew next quarter and which of them have an expired SOC 2”, Gatekeeper answers it from one view.
• The third-party portal does the chasing. Suppliers log in to upload certificates, update bank or address details, and, since February 2026, open workflow requests themselves. That takes the email loop out of onboarding and annual reviews.
• Agents with an audit trail. Agents run in three modes: Approve/Reject (can be fully autonomous), Review (recommendation only), and Form Update (fills fields; a user still submits). Gatekeeper’s own example agents are an Invoice Validator, a SOC2 Reviewer, and a Vendor Tiering Agent, which tells you where it expects the work to be.
• Finance integration that is real. NetSuite is a native two-way SuiteApp (Gatekeeper was NetSuite Partner of the Year 2024), and the integrations page lists Sage Intacct, Workday, Dynamics 365, QuickBooks, Xero, ServiceNow, Jira, Slack, and Teams, with a “1,700+ integrations” claim built by Gatekeeper’s own team.

Pricing

Gatekeeper publishes plan structure but not prices. Three tiers (Pro up to 250 third parties, Enterprise up to 750, Enterprise Plus above 750) are priced on third-party count, workflow count, integrations, and feature access. All three include unlimited users, unlimited contracts, unlimited e-signature licences and senders, agents, the AI suite, API access, SSO, the supplier portal, and the spend module. RBAC and SCIM start at Enterprise. Implementation is a separate professional-services Statement of Work.

The one public price list comes from HyperStart, a competing CLM vendor, in an article dated 1 January 2026. It shows $1,245/month for an entry tier and $2,995/month for Pro, billed annually, under plan names that no longer match Gatekeeper’s page. Treat it as a rough band, not a quote: roughly $15K/year at the bottom, $35–65K/year for an Enterprise-sized supplier base, before services. The pricing unit is the thing to model. Because users are unlimited and suppliers are metered, Gatekeeper gets cheaper per head as more of finance, procurement, and IT log in, and more expensive as the vendor list grows.

Best for

A legal ops or procurement lead at a 200–3,000 employee company with 100–750 active suppliers, a finance team on NetSuite or Sage Intacct, and no dedicated procurement suite. That is the scoped case Gatekeeper wins: vendor onboarding, renewal control, and supplier compliance in one place, at a price that does not scale with the number of colleagues who need access.

Do not buy it as your sales-contract CLM. If most of your volume is customer paper originating in Salesforce, the buy-side model works against you.

Versus the alternatives

• Ironclad: the market-share leader for in-house CLM. Pick Ironclad when the bottleneck is legal review of commercial paper and supplier management is a secondary job.
• Icertis: the other top incumbent. Pick Icertis when supplier contracts run into the hundreds of thousands under SAP or Oracle governance; Gatekeeper’s tiers top out in a different weight class.
• Sirion: pick Sirion when post-signature obligation and invoice reconciliation at supplier scale is the main problem and you will pay enterprise prices for it.
• Agiloft or Malbek: pick either when one platform must serve both buy-side and sell-side contracts with heavy custom logic.
• ContractWorks: pick it when you need a searchable repository with alerts and nothing else; it costs less and asks less of you.
• Zip and Omnea: the fastest-growing entrants on the buy side, both selling procurement intake orchestration. Pick one when the problem is purchase requests and approvals before any contract exists; Gatekeeper starts after the vendor is chosen.
• The full field is in best-clm-platforms.

Watch-outs

• Plan and feature lists disagree with each other. The July 2026 release note says the MCP connector is on every plan except Starter and ContractNow, two plans that do not appear on the pricing page, and the pricing page itself lists MCP as included on all tiers in one table and as an Enterprise Plus feature on the plan cards. Guard: get the exact plan name, its feature list, and MCP availability written into the order form, not the proposal.
• The supplier quota drives the renewal. Pipeline suppliers count toward the limit; only archived ones do not. A company that onboards aggressively can cross from Pro (250) to Enterprise (750) mid-term. Guard: archive inactive vendors before the quota check, and negotiate the overage price per additional block of third parties at signing.
• Autonomous approvals are a control decision, not a feature toggle. Approve/Reject agents can move a card without a human, and a mis-scoped Invoice Validator or SOC2 Reviewer approves the wrong vendor quietly. Guard: run every new agent in Review mode for 30 days, compare its recommendations against human decisions in the card history filter, and only then switch it to Approve/Reject.
• AI savings numbers are vendor-calculated. The AI Savings Report compares agent-delivered savings against your subscription cost, using Gatekeeper’s own method. Guard: track a baseline before go-live, such as renewals missed and hours per supplier review, and judge the agents against that.
