The 50x price difference matters
Loopio starts at ~$30,000/year — that's $2,500/month for RFP response management. FillBase starts free and scales to $599/month. For a startup doing 3–5 DDQs per month, Loopio's annual contract costs more than some teams' entire security budget.
RFP-first vs. DDQ-first
Loopio was built for RFP response — long, complex proposals with collaborative editing, approval chains, and content libraries. DDQ/security questionnaire automation is supported but secondary. FillBase is DDQ-first: grounded answers from your SOC 2 and policies, Slack workflow, source citations. Different problems, different tools.
Frequently asked questions
Can FillBase handle RFPs, not just DDQs?
FillBase handles structured security questionnaires (DDQ, SIG, CAIQ, HECVAT, VSAQ). For narrative RFP sections, Loopio or a writing-focused tool may be better.
We're growing fast. Should we start with FillBase and switch to Loopio later?
That's a common pattern. Start with FillBase while the team is small. If you grow to 10+ response staff doing 50+ RFPs/month, evaluate Loopio at that scale.
Does FillBase have a content library like Loopio?
FillBase has an AI knowledge base that learns from your documents and past responses. It's not a manually curated library — it's an AI that compounds accuracy over time.
