Trigger.dev's code-first jobs bet: v3 pivot, then a $16M Series A
Open-source TypeScript jobs platform pivots from Zapier alternative to durable AI-agent runtime; 250M executions/month and a $16M Series A by Dec 2025.
Trigger.dev
What the business is
Trigger.dev is an open-source platform for building and deploying AI agents and workflows in TypeScript: durable long-running tasks with retries, queues, human-in-the-loop approvals, observability and elastic scaling, runnable on its cloud or self-hosted; operated by API Hero Ltd in London.
Starting capital：$3M seed (Aug 2023) with Y Combinator and dev-tool founders including Supabase's Paul Copplestone and Ant Wilson, Raycast's Thomas Mann and Dropbox's Arash Ferdowsi; $16M Series A led by Standard Capital (Dec 2025).
How it started
Founded in 2022 in London by Matt Aitken, Eric Allam, James Ritchie and Dan Patel, who previously built JSON Hero. The team went through YC W23 with an idea that never quite clicked, then launched Trigger.dev as an open-source TypeScript background-jobs framework and raised a $3M seed in August 2023 after the repo passed 4,000 stars.
What happened
In 2024 the team made a key shift: instead of merely orchestrating jobs, Trigger.dev v3 builds and deploys user code to an elastic, serverless runtime with no timeouts (beta April 2024, GA September 2024; v2 EOL January 2025). The shift coincided with AI agents becoming a real category, and usage accelerated — Icon.com, MagicSchool and DavidAI run agent pipelines on it. In December 2025 Trigger.dev raised a $16M Series A led by Standard Capital (Dalton Caldwell, Paul Buchheit, Bryan Berg), with YC and earlier investors participating.
How it ended up
Still running and scaling: post-Series-A plans include MicroVM sandboxes for untrusted code, context-engineering tooling and faster run starts; the open-source repo remains actively maintained (v4.5.15 released by Sept 2026) with self-hosting via Docker and Kubernetes.
Background
Trigger.dev is an open-source platform for building and deploying AI agents and workflows in TypeScript — durable long-running tasks with retries, queues, human-in-the-loop approvals, observability and elastic scaling. It was founded in 2022 in London by Matt Aitken, Eric Allam, James Ritchie and Dan Patel, who previously built JSON Hero, and went through YC's Winter 2023 batch with an idea that never quite clicked.
Launched as the 'open source Zapier alternative', Trigger.dev raised a $3M seed in August 2023 with YC and dev-tool founders like Supabase's Paul Copplestone and Raycast's Thomas Mann. In 2024 the team made the decisive shift: instead of merely orchestrating background jobs, Trigger.dev v3 builds and deploys user code to an elastic, serverless runtime with checkpoint-restore and no timeouts (beta April 2024, GA September 2024).
The pivot coincided with AI agents becoming a real category. By December 2025 Trigger.dev reported over 30,000 developers and hundreds of millions of agent executions a month — customers include Icon.com, MagicSchool and DavidAI — and raised a $16M Series A led by Standard Capital, the new firm from YC partner Dalton Caldwell, Paul Buchheit and Bryan Berg. The team plans MicroVM sandboxes for untrusted code and a suite of context-engineering tools next.
What has to be true
- Writing tasks in plain TypeScript in the developer's own repo fit existing workflows, unlike visual no-code automation.
- No timeouts and checkpoint-restore removed the biggest pain of serverless for long AI jobs, a real differentiator against Lambda-class platforms.
- The v3 pivot from orchestrator to executor moved Trigger from a niche category to the runtime under agent pipelines.
- The AI-agent wave supplied the demand; the pivot supplied the timing, so growth came from a standing start.
What can be applied
The wedge was the programming model, not the label: shifting from orchestrating jobs to executing users' code on a no-timeout runtime put Trigger in the path of the AI-agent wave.
Aftermath
As of September 2026 Trigger.dev is scaling post-Series-A from its London base: the roadmap calls for MicroVM sandboxes to execute untrusted code, a suite of context-engineering tools and faster run starts. The platform remains open source with self-hosting via Docker and Kubernetes, the GitHub repo is actively maintained (v4.5.15 visible by Sept 2026), and the Series A post frames the mission as giving every developer a way to build production-grade AI agents without designing an orchestration system from scratch.
