Honestly, this looks like a breath of fresh air. We are constantly drowning in SIG and CAIQ requests, and the usual enterprise tools are just too heavy and expensive for our small team. The fact that FillQuestionnaire works directly in Excel without forcing us into a weird portal is huge. I love that it keeps the formatting intact, especially for HECVAT where tabs matter. The founding price is a steal too. It seems like exactly what we need to stop bottlenecking our CISO on repetitive questions. Definitely going to give this a try since the team seems focused on making this easy for sales and security folks who just want to get the job done without a six-week implementation.

The native Excel integration solves the formatting issues that plague other tools. It is a clean, focused solution for teams who need speed over complex portals.
From an analytical perspective, FillQuestionnaire addresses a specific pain point in the vendor security assessment lifecycle: the mechanical burden of data entry and formatting. By targeting the Excel-native workflow, it bypasses the friction associated with proprietary portals used by competitors like Loopio and Responsive. The claim that AI fills eighty percent of the questionnaire while flagging low-confidence answers for human review suggests a hybrid model that balances speed with accuracy. This is particularly relevant for organizations managing an average of thirty-seven assessments per month, where the time spent on manual entry can total nearly two hundred hours monthly. The pricing model is also analytically sound for small to mid-sized SaaS teams, locking in a founding rate of seventy-nine dollars per month compared to the twelve to fifty-five thousand dollar annual ranges of established players. The constraint of only twenty-five founding members creates a scarcity that may limit scalability, but for a team of one to fifty people, it offers a direct line to the creator and early feature input. The support for multi-tab files and the specific handling of HECVAT requirements indicate a deep understanding of the technical nuances that often cause errors in other systems. Overall, the platform appears to be a highly efficient tool for reducing the administrative overhead of security questionnaires.
The ability to drop in custom spreadsheets and get cell-perfect returns is exactly the convenience I needed for handling multiple weekly requests without losing my mind.

FillQuestionnaire is an Excel-native software tool designed to help SaaS companies respond to vendor security questionnaires such as SIG, CAIQ, and HECVAT. Users upload an existing Excel-based questionnaire and receive it back filled out in the same file, with answers drawn from a reusable answer library that builds over time. The service targets roles such as account executives, sales engineers, CISOs, security leads, and founders at small to mid-sized SaaS companies. A founding membership tier is offered at a discounted monthly price, limited to a set number of members, with prospective users asked to provide their role, company size, and questionnaire frequency before being contacted for a call.
