    Toyo
    2024 (founded); public seed announcement 17 February 2026

    AI-agent platform co-founded by Damien that runs agents continuously on a secure cloud computer to research, write, conduct outreach, update websites, read metrics, and operate connected business tools. Official sources describe it as an AI agent/platform for founders: https://toyo.ai/ and https://toyo.ai/blog/seed-round-announcement.

    Jelly
    28 September 2026 (initial public release)

    Open-source local-first workspace for persistent multi-bot agents, built with Bun, React, SQLite, and the Pi agent harness. It runs on a Mac, Linux box, or VM and provides a local web UI, browser control, shell tools, subagents, MCP connections, uploads, images, and artifacts: https://github.com/dctanner/jelly.

    Layercode

    An AI voice-infrastructure product co-founded by Damien, Stuart Bowness, and Aidan Hornsby before the team pivoted to Toyo after about ten months (https://betakit.com/toyo-raises-seed-funding-to-further-develop-openclaw-for-founders-tool/).

    Market Position

    Damien's work spans two complementary positions: Toyo is described as an OpenClaw-for-founders tool that makes agentic business operations accessible to non-technical operators through a secure cloud computer, while Jelly is a local-first, self-hosted alternative for users who want direct control of agent workspaces. The relevant comparison set includes OpenClaw and other agentic workflow/orchestration tools; Toyo differentiates on delegation, sandboxing, browser/app access, and founder-oriented workflows, while Jelly differentiates on local ownership and extensibility (https://betakit.com/toyo-raises-seed-funding-to-further-develop-openclaw-for-founders-tool/ and https://github.com/dctanner/jelly).

    Leadership

    Executive Team

    DT

    Damien Tanner

    CEO and Co-founder, Toyo

    Serial founder who previously co-founded Pusher, MediaCore, New Bamboo, and Panda; Pusher was acquired by MessageBird and MediaCore by Workday. Toyo's official About page lists him as CEO and co-founder: https://toyo.ai/about.

    Founding Story

    Damien describes a career that began with building applications for the Linux GNOME distribution on the HP iPAQ (LinkedIn search result: https://uk.linkedin.com/in/dctanner). He went on to co-found New Bamboo, Panda, Pusher, and MediaCore, and later started Toyo after the founding team realized that the AI agents they were using to run their voice-AI company were more interesting than the original product; Toyo's official announcement says they replaced their CRM, email automation, and website tools with agents.

    Business Model

    Revenue Model

    Toyo is presented as a paid replacement for business SaaS workflows, but public sources reviewed do not state its pricing or billing model. Jelly is MIT-licensed open-source software; running it requires the user's ChatGPT subscription or OpenAI API key (https://github.com/dctanner/jelly).
