Responsive (the rebranded Loopio, post the 2024 RFPIO + Loopio merger) is the enterprise-standard tool for proposal-content-library management. If your sales motion is enterprise SaaS RFPs across commercial accounts, Responsive is probably already on your team’s radar — and rightly so. This page exists because we get asked how WinAContract compares, and the honest answer is: we’re built for an adjacent but different problem.
What Responsive does very well
Responsive’s core competency is the answer library — a structured, versioned, searchable repository of every previous RFP/RFI/security-questionnaire answer your team has ever written, with assigned subject-matter experts, review workflows, and integrations to Salesforce, Slack, MS Teams, and the major proposal tooling. For a 50–500 person company that responds to dozens of commercial RFPs and security questionnaires a month, the time savings on "is there already a good answer to this question somewhere?" are enormous and real.
They have mature collaboration, granular permissions, SOC 2 compliance, the works. The product has been live for over a decade. For commercial-enterprise sales teams handling RFPs at scale, Responsive is the right choice — there’s a reason it’s the category leader.
Where WinAContract differs
Three places: federal specificity, opportunity discovery, and price.
On federal specificity: Responsive is industry-agnostic. It does not know what Section L and Section M of a federal solicitation are. It does not understand the compliance-matrix discipline that federal proposals demand. It does not generate first-draft narratives tuned to federal evaluation criteria. WinAContract is federal-native — the AI drafting engine is trained specifically on how federal solicitations are structured and evaluated.
On discovery: Responsive starts when you already have the RFP in hand. It does not help you find federal opportunities — that’s not its problem domain. WinAContract is search + drafting, end to end. Find the RFP, draft the response, all in one tool.
On price: Responsive is enterprise-tier, typically $15,000–$50,000+ per year depending on team size and modules. WinAContract is $1,500 list / $999 once for founding members. Different tiers, different ICPs.

Pick Responsive if…
You sell commercial enterprise SaaS, your average deal cycle involves a 200-question RFI plus a security questionnaire plus a final RFP, and you have a 5+ person proposals/RevOps team who maintains the content library. At that scale Responsive’s answer-library reuse leverage is the right ROI call regardless of price.
Pick WinAContract if…
You bid US federal contracts, you need help generating actual narrative drafts (not just retrieving pre-written answers), and you don’t have a 50,000-answer library to draw from in the first place. We’re the right tool for the first 50 federal bids of your company’s life; Responsive becomes more relevant when you’re bidding commercial enterprise deals at higher volume.
Can you use both?
Yes. A growing federal services firm with both federal and commercial business might use WinAContract for the federal pipeline and Responsive for the commercial answer library. They don’t functionally overlap.
