As answered by people managing FirstHelm and SEMRush.
FirstHelm's answer
FirstHelm is a control plane, not just a monitoring tool. Existing platforms show you what your AI agents did — FirstHelm decides what they're allowed to do. It combines live monitoring, guardrails and human-in-the-loop approvals in one place, and uniquely generates audit trails and compliance exports mapped to six frameworks (EU AI Act, ISO 42001, SOC 2, UK GDPR, NIST AI RMF, FCA) from your own live data. It's also framework-agnostic: the same control plane supervises agents built on n8n, OpenAI, Anthropic, CrewAI, LangChain, Copilot Studio, Vertex AI, Bedrock, Agentforce and more.
FirstHelm's answer
Observability tools (LangSmith, Langfuse, Helicone) trace what happened after the fact. FirstHelm intervenes before the fact: expensive, risky or irreversible actions are held for a human decision, and unanswered approvals expire safely — silence is not consent. So while competitors give developers dashboards, FirstHelm gives compliance teams proof: 38 controls, readiness scores computed live, and exportable reports an auditor actually accepts. And you keep your existing stack — FirstHelm supervises it, whatever it's built on.
FirstHelm's answer
Two groups. Developers and technical teams running autonomous AI agents in production (on n8n, LangChain, OpenAI and similar) who need visibility and a safety net. And the people holding them accountable: founders, compliance officers and operations leads in regulated or EU-exposed businesses who must evidence oversight under the AI Act and ISO 42001. FirstHelm is the bridge between them — one system both can point at.
FirstHelm's answer
FirstHelm was built in 2026 by a solo founder watching businesses deploy AI agents faster than they could govern them. Tracing tools could tell you what an agent had already done — but nothing could stop it doing the wrong thing, or prove to a regulator that someone was steering. With the EU AI Act fully enforceable since August 2026, that gap became a legal problem, not just an engineering one. FirstHelm is the answer: the helm for a fleet that was sailing itself. Bootstrapped, UK-built, live today.
FirstHelm's answer
Cloud SaaS built on the Base44 platform (frontend, backend, hosting, Postgres-backed data layer), with a REST API and Python SDK for agent integration. Payments and subscriptions via Stripe. Email infrastructure on IONOS. The product itself integrates with 13+ agent frameworks via HTTP endpoints — n8n, OpenAI, Anthropic, CrewAI, LangChain, AutoGen, Copilot Studio, Agentforce, Vertex AI, Bedrock, Azure AI Foundry, watsonx, or any custom agent.
