- TMRW
Led · Seed · Mar 2026
TMRW is creating a proactive clinical environment that leverages deep biomarker analysis to optimise patient health and longevity. Whereas most platforms report roughly 30 blood metrics, TMRW’s system interprets around 1,700 data points, giving members far richer insight into their physiology. The company has secured an exclusive Australian partnership with U.S. epigenetic leader TruDiagnostic to offer world-class biological age testing alongside its own diagnostics. CEO Mark Britt champions “building with patients,” using data to strengthen human connection and keep members in control of their health journey. Fresh seed capital will fund expansion of TMRW’s clinical footprint and refinement of its patient experience as the business evolves beyond diagnostic tools into a comprehensive care model. Many investors are already active users, signalling early alignment between product and backers.
- Operata
Led · Series A · Feb 2026
Founded in 2019, Operata develops a SaaS platform that captures and analyzes live interaction data across telephony networks and cloud contact center systems, helping operations teams quickly surface performance issues and improve customer experience. The software is tailored for fragmented, multi-vendor contact center stacks and delivers end-to-end, real-time observability. Fortune 500 companies already rely on the product, and the company now operates primarily from the United States despite its Melbourne origins. With new capital, Operata plans to deepen integrations with the major contact-center platforms and extend support for emerging AI-driven customer-service tools. It also intends to scale go-to-market and customer success teams across North America, Asia-Pacific, and Europe. The latest round values the business at $100 million, indicating strong investor confidence in its growth trajectory.
- Checkbox
Participated · Series A · Jan 2026
Checkbox offers an AI Legal Front Door that captures legal requests directly from tools such as email, Slack, Teams, Salesforce, and company intranets, then routes or automates those matters through intelligent, no-code workflows. The platform’s AI agents let business users self-serve common tasks—from drafting contracts to approving conflicts—while escalating complex, high-risk issues to legal staff. By centralizing intake and providing real-time visibility into demand, workload, and cycle times, Checkbox helps corporate legal teams improve resource planning and showcase their value to the business. More than 100 enterprise organizations, including SAP, PepsiCo, and multiple Fortune 500 firms, already use the product. Hitachi reports that 83 % of routine legal and compliance requests are now partially or fully automated with Checkbox, freeing attorneys for higher-value work. With fresh capital, the company plans to deepen AI capabilities, expand integrations across the tech stack, and drive wider adoption of its platform as the industry standard entry point for legal services.
- SecurePII
Led · Seed · Nov 2025
SecurePII develops an AI-powered, cloud-native platform focused on PCI compliance and data privacy within voice interactions. Its flagship product, SecureCall, instantly redacts sensitive details—such as credit-card numbers or other personally identifiable information—without pausing the conversation or storing call audio. By anonymising voice data on the fly, the technology lets enterprises safely feed transcripts into AI and analytics tools while remaining compliant with evolving privacy regulations. This capability reduces risk and preserves a seamless customer experience, tackling what the company calls one of the last unguarded compliance gaps in voice payments. The business intends to channel new capital into product development, deeper AI functionality, and broader sales coverage. Management also aims to forge new partnerships and accelerate the firm’s international expansion, particularly across the Americas.
- Refold AI
Participated · Seed · Aug 2025
Refold AI provides a platform that automates complex enterprise integrations using autonomous agents that learn system interactions and adapt to software changes. Its three-layer architecture supports engineers and business teams with Workflow Code Agents for engineering-created logic, MCP Chains for natural-language workflow generation, and an Embedded Integrations Platform for SaaS teams to offer native integrations. The platform handles use cases such as ERP-to-CRM synchronization and financial automation; its agents have automated financial reconciliations and established real-time data syncs in days. Refold emerged from stealth with $6.5 million in seed funding to expand its engineering team and enhance product offerings. The company works with over 30 enterprise customers, including Incorta and Naehas, supports more than 1,500 active users, and processes over 30 million API calls monthly. Founders previously created JustDoc and position Refold as a replacement for brittle, consultant-driven integration work.
