Detailed breakdown

FillBase

What it does: AI-powered DDQ completion with source-cited answers. Upload your SOC 2, policies, and past responses. Submit a DDQ in any format — get it back completed with citations.

Standout features:

• Answers grounded in your actual documents — no hallucinations
• Source citation on every answer (e.g., "SOC 2 Type II, Section 3.4")
• Learning agent that improves with every DDQ
• Confidence scoring — know which answers need human review
• Slack bot workflow — @fillbase + attach DDQ, done in minutes
• Consistency engine — same answer across all DDQs

Pricing: Free (200 req/mo), Starter $149/mo (500 req), Growth $599/mo (3,000 req)

Best for: Series A–C SaaS companies that want accurate, fast DDQ completion without buying an entire compliance platform. CTOs who are tired of being the DDQ department.

Limitations: Newer player, smaller customer base than Loopio or Conveyor.

Conveyor

What it does: Trust center + AI questionnaire automation + customer-facing security portal. Raised $19M (Series A + B).

Standout features:

• Trust center (public-facing security page)
• AI-assisted questionnaire responses
• NDA workflow built-in
• Customer portal for self-serve security info
• Browser extension for portal filling

Pricing: Custom, typically $1,000+/month. Need to talk to sales.

Best for: VC-backed startups (Series B+) that want a complete trust/security platform, not just DDQ automation.

Limitations: Expensive for early-stage. The trust center is the core product — DDQ automation is one feature among many. Overkill if you just need DDQs completed.

AutoRFP.ai

What it does: AI-powered RFP and DDQ response generation. Bootstrapped to ~$660K ARR with zero funding and 6 employees.

Standout features:

• GPT-based response generation
• Quick setup
• Affordable pricing
• Growing fast (42% MoM traffic growth)

Pricing: Starts at $69/mo, goes up to $899/mo

Best for: Budget-conscious teams, solo founders, companies just getting started with automation.

Limitations: GPT-based (not grounded in your specific documents to the same degree as specialized tools). Less enterprise-grade than Conveyor or Loopio.

Loopio

What it does: Enterprise RFP response management platform. $34.2M ARR, 1,000+ customers, 300+ employees. The incumbent.

Standout features:

• Massive library and template system
• Team collaboration workflows
• Enterprise-grade security and compliance
• Integrations with CRMs (Salesforce, HubSpot)
• Magic AI for auto-answering

Pricing: Starts around $30K+/year. Enterprise sales process.

Best for: Large companies (500+ employees) with dedicated RFP/proposal teams handling 50+ questionnaires per month.

Limitations: Overkill and overpriced for startups. Long implementation. Built for RFP teams, not CTOs filling out DDQs on a Friday night.

Vanta (Built-in DDQ feature)

What it does: Compliance platform (SOC 2, ISO 27001, GDPR) with questionnaire automation as an add-on feature.

Standout features:

• AI-generated responses, reportedly 80% auto-answered
• 95% acceptance rate on AI answers
• Integrated with your compliance data (since Vanta already has it)
• Trust center included

Pricing: Vanta platform costs $10K–$50K/year. DDQ feature included.

Best for: Companies already paying for Vanta who want "good enough" DDQ automation without adding another tool.

Limitations: You're buying an entire compliance platform to get DDQ automation. If you only need DDQ completion, that's like buying a car to use the cup holder. The DDQ feature is an add-on, not the core product — it gets less engineering focus.

Drata (Built-in feature)

What it does: Similar to Vanta — compliance platform with security questionnaire automation included.

Standout features:

• Included in Foundation and Advanced packages
• Integrated with Drata's compliance data
• Auto-mapping to frameworks

Pricing: Included in Drata platform pricing.

Best for: Existing Drata customers.

Limitations: Same as Vanta — you're buying a compliance platform. DDQ automation is a feature, not the focus.

The bottom line
