About RODMEN/A
Building durable software platforms for mission-critical work.
Our Mission
RODMENA LIMITED is a London-based software company that builds production-grade software platforms — workflow orchestration, distributed systems and the tooling around them.
Our flagship product, Highway Workflow Engine, represents years of experience building reliable, fault-tolerant systems. We've distilled lessons from data infrastructure at scale into a workflow engine that provides bank-grade reliability without the complexity.
We believe workflow automation should be simple to implement, impossible to break, and built on technology you already trust. That's why Highway is PostgreSQL-native: if you run Postgres, you're ready for Highway.
Beyond Highway, we provide consulting and implementation services using proven technologies like Python, Erlang/Elixir, PostgreSQL, and AWS.

What we build
Durable, mission-critical software platforms — workflow orchestration, email infrastructure, container execution, and human-in-the-loop control.
Highway
Bank-grade durable workflow orchestration, powered by PostgreSQL.
Bank-Grade Atomicity
Application data and workflow state commit in the same PostgreSQL transaction. Never partial failures.
PostgreSQL-Native
Single source of truth. No Kafka, no Redis, no external queues. Zero infrastructure overhead.
Durable Execution
Workflows survive crashes and restarts. Automatic resumption ensures no work is ever lost.
Python DSL
Define complex workflows with simple, readable Python. No boilerplate, no complexity.
Event-Driven
Human-in-the-loop workflows, webhooks, and fan-out/join patterns out of the box.
Circuit Breakers
Automatic failure detection and recovery. Prevents cascading failures in distributed systems.
Multi-Tenant
Complete data isolation with row-level security. Enterprise-ready from day one.
Audit Trails
Immutable event logs for compliance. Time-travel queries for historical state.
MailApi
Multi-tenant outbound email API with templates, campaigns, webhooks, scheduling, and MCP server.
Transactional & Marketing
Send transactional, notification, marketing and legal email with calendar-enforced scheduling and full lifecycle tracking.
Jinja2 Templates
Sandboxed Jinja2 templates with strict rendering — missing variables block the send, not silently blank.
Bulk Campaigns
Create and manage bulk campaigns with suppression lists, calendar compliance, and real-time status tracking.
AI-Native MCP Server
AI agents send email directly via the MCP protocol — no glue code, no SDK, one endpoint call.
Webhooks & Lifecycle
Full email lifecycle webhooks with HMAC-SHA256 signing, exponential backoff retry, and delivery history.
Inbound Email
Receive, retrieve and manage inbound email with attachment support and acknowledgment marking.
RunFlow
Governed execution sandbox for running Docker containers remotely — with full lifecycle control, DAG workflows, and MCP-native access.
Hardened Sandbox
Dropped capabilities, read-only rootfs, no-new-privileges, and per-job network isolation — safe for untrusted code.
Freeze & Resume
Pause a live computation mid-flight preserving in-memory state — resume exactly where it left off, no checkpointing code needed.
DAG Workflows
Fan-out/fan-in pipelines with conditional branching, retries, JSON data passing between nodes, and human approval gates.
Live Observability
Streaming logs, real-time CPU/memory/network utilisation, and full state-transition history for every run.
Queue & Schedule
Jobs queue with position and ETA when at capacity; schedule for future time or defer to business hours.
41 MCP Tools
Every operation exposed via MCP — AI agents connect by URL and API key, no SDK or glue code needed.
Futex
Multi-tenant control plane for AI agents to request policy-driven human decisions — durably, asynchronously, at scale.
Policy-Driven Approvals
Multi-stage approvals, quorum (n-of-m), separation of duties, and SLA escalation — all defined per policy, not hard-coded.
Non-Blocking Architecture
Agents request a decision and get an ID back immediately — poll or receive a webhook when a human reviews it.
Human Review Surface
Reviewers get an email with a secure link to approve, reject, delegate, or escalate — no dashboard login required.
Delegation & Escalation
Out-of-office delegation reroutes tasks automatically; SLA breaches trigger escalation to senior reviewers.
Durable & Audited
Transactional outboxes, idempotent decisions, and every action audited with acting_as and timestamp.
Multi-Tenant Isolation
Hard tenant boundaries with keys scoped to tenant plus principal. Fail-closed on auth outages.
reTunnel
Free, open-source unified ingress platform — expose local servers behind NATs and firewalls to the public internet over secure tunnels.
Single-Command Tunnels
Expose a local server in one command — `retunnel http 8080`. No sign-up required for basic usage, no boilerplate.
Encrypted by Default
All connections are encrypted end-to-end. Serve public HTTPS URLs from your local machine without managing certificates.
HTTP, HTTPS & TCP
Tunnel web services and raw TCP — SSH, databases, custom protocols — from behind NATs and firewalls to a public endpoint.
Webhook Debugging
Inspect and replay inbound webhook events from Stripe, GitHub, Slack and more. Develop and test integrations in real time.
Subdomains & Auth
Reserve a custom subdomain and protect any tunnel with HTTP Basic Auth — via CLI flags or a declarative retunnel.yml config.
Self-Hostable & Open Source
Run your own reTunnel server for full control, or use the managed platform. MIT-licensed, built on asyncio with a Typer CLI.
