The short version

[ VERDICT ]

Choose Tussell when the job is understanding the UK market: spend, frameworks and call-offs, analyst-verified signals and research. Choose Stotles when the job is working opportunities: a free entry tier, AI bid/no-bid reports, native CRM sync and an MCP connector.

  1. 01Both are UK-focused. Stotles lists UK and Irish portals plus TED; Tussell is UK only. Neither covers NATO agencies or continental national portals.
  2. 02Both hold spend and contact data, measured differently: Stotles cites 200m+ buyer invoices and 3m+ buyer contacts; Tussell 81,000+ decision-maker contacts across 4,500+ UK buying organisations, plus framework lot intelligence.
  3. 03Stotles has generative AI: bid/no-bid reports over uploaded documents, Q&A and first drafts. Tussell uses AI to flag buying signals that analysts then verify, and documents no generative assistant.
  4. 04Stotles syncs natively with Salesforce and HubSpot and has an MCP connector. Tussell feeds CRMs and BI tools through a paid daily file API.
  5. 05Stotles publishes entry prices and auto-renews contracts unless given 45 days’ notice. Tussell is quote-only, on an annual subscription.

The differences that matter

[ 04 POINTS ]

Data depth

Tussell is the stronger research dataset: tenders, awards, frameworks and call-offs, framework lot intelligence, spend and early opportunities from central government, local government and NHS documents, each verified by an analyst. It publishes widely cited trackers, including a UK defence procurement tracker, and offers bespoke analyst research.

Stotles covers similar UK ground with a sales lens: pre-tenders, expiring contracts, buyer documents, invoices and contacts, organised around buyer profiles and competitor tracking. Tussell’s framework and call-off detail is the clearest gap between them.

Workflow and AI

Stotles runs two studios. Sales Studio handles the feed, buyers and outreach; Bid Studio produces AI bid/no-bid reports from uploaded tender documents, answers questions about them, and keeps a content library for first drafts. Its platform page still lists automated bid drafting as coming soon, so check what your plan includes.

Tussell documents no pipeline or bid workflow. Its model is data plus people: a named account manager, analyst-verified signals and research on request.

Integrations

Stotles syncs notices and contacts to Salesforce and HubSpot, posts to Slack, lists Teams, SharePoint and Google Drive, and since August 2026 offers an MCP connector for Claude, ChatGPT and Microsoft 365 Copilot on paid plans. We found no public REST API.

Tussell’s paid API delivers daily files on AWS S3, which it uses to feed HubSpot, Salesforce, Dynamics, Power BI, Tableau, Slack, Teams and others. Web app data downloads as CSV. We found no MCP connection.

Contract terms and trials

Stotles’ terms extend the agreement automatically by the original term unless you give 45 days’ notice. Its free tiers act as an open-ended trial.

Tussell sells annual subscriptions. Its G-Cloud sample order form sets a 12-month minimum with no auto-renewal and no cancellation mid-term, and its trial runs seven days with one page of results and no export. Downloaded data carries a 364-day licence. See the export guides for Stotles and Tussell.

Where Defense Explorer fits

[ THIRD OPTION · OUR PRODUCT ]

We sell a product in this category. This section is ours; the rest of the page is about the two products above.

Both products are UK-focused. If your bids also go to NATO agencies such as NSPA or to continental defence ministries, Defense Explorer covers those sources and adds defence relevance and clearance classification, cited briefs and recorded bid decisions. It has no contacts or spend data, so it complements rather than replaces either product for UK account planning.
