About Archipelo

Archipelo develops Salmon, Execution Verification Infrastructure for establishing cryptographically verifiable execution history and state lineage. Archipelo builds Salmon for autonomous multi-actor software systems. Archipelo, Inc. is the company developing and stewarding Salmon.^[1][3][4][5]

Archipelo states that autonomous agents, tools, runtimes, and controllers increasingly perform consequential actions themselves. Archipelo states that the resulting state alone cannot show which execution occurred, in what order, or how each state transition derived from the ones before it. Archipelo develops infrastructure that makes autonomous multi-actor software execution independently verifiable. Archipelo states that safe and reliable agents need verifiable evidence of their execution history.^[4][5]

Archipelo points to Git as showing the value of persistent, linked source code history. Archipelo says Execution Verification Infrastructure addresses a different problem, which is establishing a verifiable record of state transitions and the resulting state.

Archipelo describes execution as represented by a cryptographically signed event with explicit context. Archipelo states that Salmon captures execution as it occurs upstream within supported environments, not downstream after the event has already taken place. Archipelo states that Salmon does not visually or structurally manufacture execution continuity when execution continuity has not been established.

Archipelo states that agent generated changes can involve delegated execution, tools, subprocesses and multiple state transitions. Archipelo states that execution history provides a durable record of supported execution relationships to verify outcomes. Archipelo states that during incident investigation, teams need to work backward from a consequential state change toward the execution associated with it, to determine what caused the outcome.

One principle is that downstream systems should not be forced to establish execution history solely through retrospective inference where it can be captured during supported execution. Archipelo states that what an actor was permitted or instructed to do is distinct from what it actually executed. Archipelo states that machine-speed software systems require execution evidence that other software systems can consume and verify. Archipelo describes identity, policy, observability, security, engineering, and governance systems as solving adjacent problems.^[5]

Archipelo describes itself as a deep tech company building foundational infrastructure for verifiable autonomous systems.^[1][3][4][5]

About Prime Security

Prime Security sells an AI security review platform designed for software development lifecycles. Prime Agents learn an organisation's architecture, code and risk history. Prime Security describes one platform covering the SDLC before the code, in the code and after the code. Prime agents work autonomously inside the customer environment, mapping every application, policy, resource and data flow. Prime agents live inside the development lifecycle and understand designs, code, cloud and policies.^[1][2][3][4]

Prime Security says AI agents, multiple stacks and complex development processes have created an attack surface that no existing security tool was built to handle. Prime Security states its aim as connecting architecture, code and cloud to find every exploitable attack vector before attackers do. Prime tracks every asset as it moves from design to deployment. Prime learns an organisation's architecture, past decisions and risk profile, and each review builds on the last one.^[3][4][5]

Autonomous design reviews use AI agents to review specs, architecture and data flows to uncover security risks before code is written. Prime checks every design, scores every risk and validates every fix in code. Prime can produce a threat model, and Prime combines design-level analysis with actual code. Prime Security covers architecture reviews, threat modeling, documentation analysis, and security analysis tied to tickets and code changes. Prime finds vulnerabilities and logic flaws in AI-generated and human-written code. Prime checks every PR the moment it opens, whether a developer or an agent wrote it. Prime checks each pull request for approved auth flows, encryption methods, architecture patterns and framework requirements. Prime reviews every PR against the policies that apply to that repo, validates each finding and hands the agent the context to fix it. Prime logs every review, finding, validation and fix.^{[1][2][3][4][6]}

Prime sets security guardrails for agents like Cursor and Claude Code, catching insecure code at the PR before it merges. Prime Security embeds security policies directly into AI coding workflows. Prime inventories every package in the dependency graph, direct and transitive, and matches it against known CVEs and the license policy. Prime identifies vulnerable packages accessible to attackers with proven attack paths. Exploitable findings arrive with the full attack path, and unreachable ones arrive marked as noise, with the reasoning attached. Prime checks every dependency against the license policy in the same scan. Prime runs continuous attack path analysis with source, architecture and controls. Prime maps how services talk, where data flows and how an attacker would chain it all together. Prime evaluates multi-step attacks the way an attacker plans them.^[1][3][4][7]

Prime delivers a tailored fix wherever the work happens, with the PR, Slack or a Jira ticket for developers. For dev agents, Prime delivers context over MCP, so mitigation runs with no human in the loop. Prime proposes mitigations built for the codebase, delivers them to developers and agents and validates the fix landed in code. Agents run continuously across planning and development workflows without requiring custom engineering from the customer team. Prime integrates with Github, Gitlab, Claude Code, Cursor, Jira, Confluence, Google Drive, Azure DevOps, Linear, and Git Issues.^[2][3][4]

Prime Security supports Product Security Engineers and Security Architects. MX adopted Prime Security. MX is a financial data platform that powers secure data access, analytics, and personalized money experiences for banks, fintechs, and financial institutions. Oscar Health adopted Agentic Security Architect from Prime to automate security reviews and proactively identify risk across all engineering work. Oscar Health is a healthcare technology company that combines digital experiences with health insurance services. ThoughtSpot adopted Agentic Security Architect from Prime to scale security reviews and threat modeling across its expanding engineering surface area. ThoughtSpot is an analytics platform that enables organizations to explore, analyze, and act on data at scale.^{[1][4][8][9][10]}
