Responsive Alternative

We are a small SaaS team looking at RFP and questionnaire tools, and Responsive.io came up a few times, but our setup is a bit specific: sales needs fast first drafts, security wants clear citations, and leadership cares about overall win rate. Exploring alternatives that can handle this mix without a heavy rollout

1. Inventive AI: AI‑first RFP workspace that drafts from our existing docs with citations and a confidence score so SMEs can review instead of starting from scratch.

2. Tribble: Slack‑first agent that helps with RFP and security questions directly in channel so stakeholders can respond without changing tools.

3. Sifthub: knowledge hub that keeps technical and product information consistent so responses across different deals do not drift.

if you have used Responsio.io and then switched, would be keen to hear what you moved to and why it fit better
