How Insight Assurance Helped SIGQ Build Early-Stage SOC 2 Trust

How Insight Assurance Helped SIGQ Build Early-Stage SOC 2 Trust
About SIGQ Inc.

SIGQ Inc. is an early-stage Japanese startup building an AI-powered incident management platform. With a team of seven, they serve large enterprises and financial institutions in Japan, where customers and investors expect strong security practices and recognized frameworks such as SOC 2 and ISMS.

From the beginning, CEO Takaaki Kanetsuki wanted security to be part of SIGQ’s foundation. Having led SOC 2 efforts three times at a previous company, he decided SIGQ would pursue SOC 2 at a very early stage, even before fully releasing the product, so the company could speak credibly with security and procurement teams from day one.

The Challenge

SIGQ’s customers include listed companies and banking-backed venture capital firms. These stakeholders ask detailed questions about information security, but young startups often need help providing structured, audit-ready evidence.

In Japan, SOC 2 audits are often expensive and delivered through traditional, email-heavy processes. For a seven-person team, that model would have been difficult to support. SIGQ needed an independent audit firm that could move at startup speed and work comfortably with their existing tools without overloading engineers.

The Solution

SIGQ first met Insight Assurance at a Vanta community event in Japan. After that in-person introduction, they selected Insight Assurance based on three factors: cost, a Slack-based communication model, and an audit timeline that fit startup realities.

Using Vanta as their compliance platform, SIGQ worked with Insight Assurance to prepare the documentation and evidence required for the SOC 2 examination. According to Kanetsuki, the team was able to follow the roadmap without trouble, and they encountered no major issues during the audit itself.

Most communication took place on Slack, with only a few online meetings. This matched how SIGQ’s engineers already worked and kept context in one place. Kanetsuki highlighted how quickly Insight Assurance responded, often within about an hour, which helped the team address audit questions while balancing feature development and preparation activities.

Technology Environment

SIGQ used Vanta as part of its internal compliance tooling. Insight Assurance worked within SIGQ’s existing environment, maintaining a platform-agnostic approach throughout the audit. The engagement did not require SIGQ to adopt new tools or change its core systems. This ensured that the audit could be completed within the company’s existing operational structure.

The Results

SIGQ successfully completed its SOC 2 audit at a very early stage, giving the company a concrete way to demonstrate its security posture to demanding enterprise customers and security-focused investors. Before the audit, SIGQ had no formal method to present its security level; with the SOC 2 report, they can now share clear, third-party-validated evidence.

The work also strengthened internal practices. SIGQ aligns device protection, deployment flows, and day-to-day engineering habits with SOC 2 expectations, helping employees internalize security requirements as the company grows.

Externally, the impact is already visible. Most of SIGQ’s customers are listed companies and their subsidiaries, and some do not yet have their own SOC 2 reports. When SIGQ presents its report, customers are often surprised that such a young startup has reached that level of assurance, and security reviews progress more smoothly.

The experience has shaped SIGQ’s roadmap as well. The company is preparing for SOC 2 Type II and has begun work on ISO/IEC 27001, ISO/IEC 27017, and AI-focused ISO/IEC 42001. Kanetsuki plans to introduce Insight Assurance to other startups building AI platforms and intends to continue partnering with the firm as SIGQ scales.
