Tendarix

Tendarix presents the broadest free feature set in this batch: hybrid matching, buyer intelligence, renewal radar, collaboration, bid drafting, CSV and API access. Its main weakness is not feature breadth but operational proof: the live council-coverage page shows a small active subset and many broken or pending sources, while identity, renewal, security and service-level methods remain thinly documented.

Normalized features

Capability-by-capability evidence

Yes means the complete normalized capability is available in at least one current plan. Partial means the implementation is adjacent, incomplete or materially narrower. Missing public evidence defaults to not offered.

AI or semantic matching

Yes

Each tender is scored against a company profile, geography, capacity and past performance using advertised hybrid keyword and semantic matching.

Tendarix home ↗

Buyer profiles

Partial

A buyer page is said to aggregate award history, top suppliers, average deal size, SME share and renewal timing across notices, but the reviewed pages do not establish canonicalisation, deduplication or entity-resolution investment for buyer identities.

Tendarix home ↗

Supplier profiles

Not offered

Buyer profiles show top suppliers and competitor tracking is advertised, but structured standalone supplier, incumbent or winner profiles are not established on the reviewed public pages.

Renewals

Yes

Renewal Radar is advertised on buyer profiles and is said to flag likely rebid windows six to nine months before a subsequent notice.

Tendarix home ↗

Similar contracts

Not offered

Past performance influences matching and buyer award histories are available, but the reviewed pages do not say that comparable historical contracts are surfaced against a notice or profile.

Buyer document corpus

Not offered

The reviewed pages do not establish buyer plans, strategies, minutes, budgets or other buyer-authored document intelligence beyond procurement notices.

Buyer requirements

Partial

A limited free tender summariser advertises an eligibility checklist, key dates, complexity rating and bid/no-bid score from a supplied tender URL; platform-wide structured requirements coverage is not described.

Tendarix home ↗

Requirements planning

Partial

The eligibility checklist, bid/no-bid score and pipeline support basic qualification and preparation, but no full requirements-gap or evidence-planning workflow is documented.

Tendarix home ↗

Award history

Yes

Buyer profiles include award history and suppliers; the service also advertises buyer award history for renewal research.

Tendarix home ↗

Frameworks

Partial

Tendarix says it watches framework call-offs, but the reviewed pages do not document a dedicated framework, DPS or dynamic-market intelligence module.

Tendarix home ↗

Competitor tracking

Yes

Competitor tracking is listed in the free plan, alongside buyer top-supplier and award-history data.

Tendarix home ↗

Exports or API

Yes

The free plan lists CSV export and API access; consultancy workspaces also advertise webhooks and an API.

Tendarix home ↗

Team workflow

Yes

The service advertises saved searches per client, shared comments, a pipeline board, assignments, multi-profile workspaces and Slack alerts.

Tendarix home ↗

Bid writing

Yes

The free plan advertises unlimited bid drafts and AI summaries and bid scoring.

Business and product

Legal identity and maturity

Strong evidence

Tendarix's terms and footer identify Unique Evolution Limited as operator. Companies House records UNIQUE EVOLUTION LTD, company 14243073, as active and incorporated on 19 July 2022; the operator's studio site identifies Tendarix as a Laravel and Meilisearch product with live search, AI analysis, buyer profiles, bid pipeline and a readiness module.

Tendarix terms ↗Companies House: Unique Evolution Ltd ↗Unique Evolution studio and Tendarix case entry ↗

Target customer and use case

Strong evidence

The homepage explicitly targets UK SMEs, sole traders, internal bid teams and bid consultancies. It positions onboarding as a ten-minute company profile that narrows tender feeds, supports renewal prospecting and creates shared multi-client bid workflows.

Tendarix home ↗

Commercial model

Strong evidence

The current Tendarix Member plan is explicitly free, with no card and no trial, and advertises unlimited searches, alerts and bid drafts plus full buyer intelligence, competitor tracking, CSV and API access. Terms reserve the right to add, change or remove features. Public pages do not state user limits, fair-use controls, API quotas, advertising economics or a future paid model; the privacy policy permits Google AdSense on public content pages.

Tendarix pricing ↗Tendarix terms ↗Tendarix privacy policy ↗

Security, support and onboarding

Moderate evidence

The privacy policy identifies Unique Evolution Limited as controller and describes account, business-profile, usage, device, location and cookie data. The homepage promises ten-minute setup and priority support, but no security-control page, DPA, named subprocessor schedule, hosting region, fixed retention periods, certification, status history, backup objective or service SLA is public. The terms provide the free service as-is without uninterrupted availability.

Data and discovery engine

Sources and coverage method

Moderate evidence

Tendarix explicitly names six national feeds: Contracts Finder, Find a Tender, Public Contracts Scotland, Sell2Wales, eTendersNI and TED. It separately claims more than 400 buyer portals and publishes a 394-council coverage table with vendor labels including In-tend, Bravo and ProContract, but the table's active, broken and pending states materially limit the breadth implied by the headline.

Tendarix home and national feeds ↗Tendarix council coverage ↗

Ingestion and freshness

Moderate evidence

The homepage shows live counts, source links and a next-update timer and claims national and local feed monitoring. The coverage page is unusually transparent about scrape status, but at research time showed only 31 active of 394 tracked councils, four contracts indexed and 52 successful scrapes in the preceding 30 days. The site does not explain validation, deduplication, failure recovery or why it uses both twelve-hour and hourly refresh claims.

Tendarix home ↗Tendarix council coverage and scrape status ↗Tendarix terms and source verification ↗

Matching and qualification

Strong evidence

Tendarix describes hybrid keyword and semantic search, scoring each tender against company profile, geography, capacity and past performance. Onboarding accepts CPV codes, geography, team size and past performance and extracts company data from Companies House; results include match score, urgency and a plain-English brief. No model evaluation or false-positive benchmark is public.

Tendarix home and match engine ↗

Historical and award depth

Moderate evidence

Buyer profiles include award history, suppliers, spend and average deal size, and competitor tracking is advertised. The reviewed pages do not publish the award date floor, completeness by feed, winner normalization, relationship accuracy or direct comparable-contract surfacing.

Tendarix buyer and award intelligence ↗
Deep audit

Intelligence depth

Buyer entity investment

Moderate evidence

Buyer pages aggregate award history, top suppliers, average deal size, SME share, spend and renewal timing across records. This is useful structured cross-notice intelligence, but the reviewed pages do not establish canonicalization, aliases, deduplication, organizational hierarchies or entity-resolution controls, so normalized buyer profiles remain partial.

Tendarix buyer intelligence ↗Unique Evolution Tendarix case entry ↗

Supplier entity investment

Not found

Buyer pages expose top suppliers and the free plan advertises competitor tracking, but no canonicalized standalone supplier entity, alias-resolution method, cross-buyer supplier profile or supplier correction process is established in the reviewed first-party material.

Tendarix home ↗

Renewal-signal method

Weak evidence

Renewal Radar is presented as a complete product feature and the homepage claims it flags a rebid window six to nine months before the next notice. The public pages do not explain whether that timing comes from published end dates, contract duration, historical cycles, machine prediction, extension records or confirmed pipeline notices, and no accuracy evidence is provided.

Tendarix renewal radar ↗

Requirements-planning method

Moderate evidence

A limited summarizer produces an eligibility checklist, key dates, complexity rating and bid/no-bid score, while the platform offers a bid pipeline and the operator's case entry names a readiness module. No public workflow shows durable requirement records with gaps, evidence needs, owners, remediation actions, deadlines and tracked readiness, so the normalized capability remains partial.

Tendarix home and tender summarizer ↗Unique Evolution Tendarix case entry ↗

Workflow and integrations

Strong evidence

Tendarix documents saved searches with email and Slack alerts, bookmarks, shared comments, assignments and a pipeline board. Consultancy use adds multi-profile workspaces, and the free plan lists CSV export and API access while the consultancy section also names webhooks; public limits and integration documentation are not stated.

Limitations, contradictions and questions

Material limitations

  • The live council table materially narrows the 400-plus-portal claim: only 31 of 394 tracked councils were active at research time, with many entries broken or pending and very low recent scrape and indexing counts.Tendarix council coverage ↗
  • Buyer profiles are structured but lack published identity-resolution evidence, while standalone supplier entity investment is not established.Tendarix buyer intelligence ↗
  • Renewal Radar gives a six-to-nine-month commercial signal without disclosing its source fields, prediction method, extension handling, confidence or back-tested accuracy.Tendarix renewal radar ↗
  • The readiness and summarizer material does not establish a complete durable requirements workflow with evidence gaps, owners, actions and readiness state.Tendarix home ↗Unique Evolution Tendarix case entry ↗
  • The free plan advertises unlimited AI, team and API features, but no fair-use, user, API, data-export or support limits are published and the terms permit feature changes without a paid service commitment.Tendarix pricing ↗Tendarix terms ↗

First-party contradictions

  • The homepage claims more than 400 buyer portals and says every portal is watched, while the live coverage page listed 394 councils with only 31 active and many broken or pending sources. The operational table does not support treating the headline as fully active coverage.Tendarix home ↗Tendarix council coverage ↗
  • The homepage says feeds are updated every twelve hours near the source list but later says every portal is watched every hour. A source-specific cadence or explanation for the two figures is not published.Tendarix home ↗
  • The operator's studio site repeatedly says established in 2000, while Companies House records the named legal operator as incorporated in 2022. The earlier date may refer to personal or predecessor experience, but that distinction is not stated.Unique Evolution studio ↗Companies House: Unique Evolution Ltd ↗

Questions to ask

  1. Which of the 394 listed council sources are currently production-active, what proportion of their notices is ingested, and how are broken scrapers detected and repaired?
  2. Why do public pages state both hourly and twelve-hourly monitoring, and what measured publish-to-index latency applies to each national and local source?
  3. How are buyer names canonicalized, deduplicated and corrected, and is there a supplier entity layer behind competitor tracking?
  4. What data and model produce the six-to-nine-month rebid window, how are extensions and confirmed successor notices handled, and what back-tested precision is achieved?
  5. Can the readiness module assign owners, actions, evidence and deadlines per requirement and maintain an auditable readiness state?
  6. What fair-use, user, API, export and AI limits apply to the free plan, and what continuity or migration commitment applies if pricing or features change?
  7. Can Tendarix provide a DPA, named subprocessors, hosting and retention details, security controls, penetration assurance, backup objectives and support or uptime commitments?
