Where the vendor descriptions differ
- Where the firm's knowledge comes from: Kantiv says it unifies proposals, project narratives, resumes and client history from drives, inboxes and old proposals into an AEC data model of people, projects, clients and pursuits. Workorb says its Knowledge Hub connects to CRM, ERP and document systems and that AI agents organize and clean past proposals, project sheets and team bios, with no manual uploads.
- Drafting: Kantiv describes uploading an RFP for a structured first draft built from the firm's past wins, with technical staff contributing directly. Workorb describes RFP summaries, suggested past projects and team members matched to the requirements, and first drafts of proposals and fee letters in the firm's writing style.
- Compliance and review: Kantiv lists requirement tracking, addendum syncing and compliance checks before submission. Workorb says its AI acts as an evaluator that checks the submission against the RFP requirements, proofreads it and critiques the draft.
- Go/no-go: Kantiv describes win and loss visibility by client to inform go/no-go calls. Workorb says it can evaluate RFPs against the firm's own Go/No-Go scorecard.
- Other features: Kantiv lists SF-330 completion, resume generation and Image Hub, which auto-tags photos by what is in them. Workorb's pricing page lists a Proposal Assistant, a Document Assistant and brand voice and tone on its Enterprise plans.
- Integrations and security: Kantiv says it integrates with Deltek, SharePoint and Egnyte, and its homepage describes it as SOC 2 Type II certified. Workorb shows connections to Deltek Vantagepoint, Unanet CRM, SharePoint and OpenAsset; we did not record a security certification on the two Workorb pages we read.
- Pricing (checked Oct 19, 2026): Workorb lists the RFP & Proposal AI Evaluator at $175 per user per month on a monthly commitment or $149 on an annual one, with no credit card required to try it; Workorb Enterprise and Enterprise with Knowledge Hub are custom pricing. Kantiv's Pricing & ROI page is an ROI calculator with no plan prices.
- Vendor claims (not verified): Kantiv cites 200+ AEC teams, $2.4B+ in proposals submitted and 50% less prep time; Workorb claims a structured first draft in about 30 minutes, most firms running in about 48 hours, and no hallucinations. Not measured the same way; neither tool has been tested by Means & Methods Lab.
Paraphrased from the sources listed above. Vendor claims are reported as claims.
What we can't tell you yet
Which tool is better for your work. That needs testing on the same package with a verified answer key. Planned measures for this comparison:
- Share of drafted sections a proposal manager keeps after review on the same RFP
- Requirement misses in each tool's compliance check against a hand-built compliance matrix
- Outside Means & Methods Lab's current benchmark scope.
