In short
Altura and TenderRender both use AI across the bid process, and their feature lists overlap more than you might expect. Altura, according to its website, is bid management software for complex, multi-stakeholder bids: configurable AI workflows for solicitation, requirement and risk analysis, clarification questions and submission readiness, all synced in a shared Bid Book, with structured onboarding of several weeks. TenderRender is lighter and centered on the proposal itself: it analyzes the solicitation with a citation for every answer, drafts clarification questions, writes each answer from your own content library in your own voice, fills in required forms and scores your draft per evaluation criterion. Pick Altura if your main challenge is coordinating many contributors on large pursuits. Pick TenderRender if your main challenge is writing a strong, compliant proposal quickly with a small team.

What does Altura do?
Altura calls itself bid management software for complex bids, built to automate the lifecycle of multi-stakeholder pursuits. According to its website:
- Bid Book. A shared data table where every stage of the bid lives, kept in sync as documents and Q&A answers change.
- AI workflows. Solicitation analysis, requirement analysis with draft responses from your Knowledge Library, risk analysis against your own red flag criteria, clarification questions with reasoning and a recommended strategy, and a submission readiness check for forms, certificates, page limits and signatures. Every finding links back to the source.
- Platform. Opportunity Discovery, a Deal Board, a qualification tool and Bid Companion for asking, searching and writing.
- Custom workflows. Altura's team builds workflows for processes the standard ones do not cover, on its top plan.
- Onboarding. Structured onboarding of four to six weeks on Starter, six to eight on Professional and twelve on Advanced, plus bid manager training.
Altura states it is ISO 27001 certified, GDPR compliant, hosted in the EU and never uses customer data for training. For a mature bid office running many large pursuits with legal, finance and technical contributors, that depth is the point.
What does TenderRender do?
TenderRender focuses on getting from solicitation to a reviewed proposal:
- Analyze. The AI reads the full solicitation and answers your questions, with a citation that opens the right page.
- Clarification questions. TenderRender drafts questions for unclear or contradictory requirements, with its reasoning. We test these internally against real Q&A rounds.
- Submission checklist. A list per phase of every document you need to submit.
- Write. After a few targeted questions, the AI drafts full answers per evaluation criterion from your own library, in your own voice. Colors show where each passage comes from.
- Forms. Required forms are filled in with your company details. Anything it cannot support stays blank.
- Evaluate. A score per evaluation criterion with specific fixes.
TenderRender is ISO 27001 certified, stores data in the EU and does not train on customer data. Its opportunity search covers public bids in the Netherlands, Belgium and Germany only, so for US work you upload the solicitation yourself.

Who is each tool for?
Altura fits you if you run a mature bid office with many simultaneous pursuits and dozens of contributors from legal, finance and operations, and you are ready to invest weeks in configuration so the platform follows your process.
TenderRender fits you if you are a small or mid-sized proposal team, or BD staff who write proposals on top of other work, and your bottleneck is writing: getting from solicitation to a strong, compliant first draft and knowing where it will lose points.
Still unsure? Ask what slowed down your last proposal. If it was chasing SMEs and keeping versions in sync, you need process control. If it was the blank page and the final review, you need drafting and scoring.
How should you test both?
Run the same recent solicitation through both tools. Measure time to a usable first draft, whether every claim traces back to a source, how useful the review is to an experienced proposal manager and what your team still uses after a week. A longer feature list only matters if it removes work you actually do.
