Virtuoso QA
Virtuoso QA is a secure, agentic test automation platform for any browser-based application. Touchstone, our agentic assurance layer, turns your business requirements into tests, then runs, fixes and maintains them as your application changes. More than thirty specialised agents author, generate, triage and self-heal your functional and end-to-end tests, while a deterministic engine executes every run and your team approves every decision that matters. Every release comes with evidence of what was tested, what changed and who approved it. Release Insights shows execution risk and requirement coverage across every journey, and teams can export an Evidence Report in minutes rather than assembling one over weeks. That makes the platform a natural fit for regulated industries like financial services, insurance, healthcare, the public sector and more. The mission is to set the standard of proof for software releases. AI generates software. Virtuoso QA generates the evidence to trust it.

Checksum.ai
Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap. Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery. The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team. Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required. The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.
