Stacksi

Stacksi operated as a cloud-based platform providing tools for sales security questionnaires before its acquisition by SafeBase in September 2023. Founded in 2020 by Joseph Metzinger and led by CEO Emre Murray Mangir, the San Francisco-based company emerged from the Y Combinator accelerator program, securing $125,000 in a seed round in 2021. Both Stacksi and its acquirer, SafeBase, were part of the Y Combinator program, fostering a shared commitment to customer-centric solutions for streamlining security reviews.

The company's core business focused on automating the often complex and time-consuming process of completing cybersecurity audits and security questionnaires required in B2B sales cycles. Stacksi targeted fast-growing enterprise startups that needed to establish robust cybersecurity policies to close deals but often lacked the dedicated resources. Its platform leveraged Artificial Intelligence (AI) and Natural Language Processing (NLP) to analyze a company's existing security documentation and automate responses to security questionnaires. This process helped identify gaps against security standards and assisted clients in improving their overall security programs.

The service functioned by allowing users to upload security questionnaires and policies, which the system would then analyze to populate answers automatically. For any remaining questions, the platform facilitated collaboration by tagging employees across different departments, such as sales and engineering, to provide the necessary information directly within the interface. This workflow was designed to reduce the back-and-forth communication that typically slows down the security review process. By acting as a single source of truth, Stacksi aimed to save its clients time and money, accelerate sales, and allow engineering teams to focus on other critical tasks.
