“Effect makes doing the hard, tedious, and error-prone tasks that require discipline, easy, natural, first-class.”
Dillon Mulroy, Cloudflare
September 10–11, 2026
A structured workshop that takes engineers from Effect fundamentals to production-ready expertise. The inaugural cohort runs September 10–11, 2026 — agent-native by design, with recurring cohorts and potential in-person sessions at Effect Days to follow.

Reserve Your SeatAbout Effect
Effect is the emerging standard for production TypeScript — composable primitives for error handling, concurrency, dependency injection, and resource safety. Where traditional TypeScript leaves you writing defensive boilerplate, Effect gives you a type-safe, composable toolkit that makes complex programs easier to reason about, test, and maintain.
With 20M+ weekly downloads and production adoption at Zendesk, MasterClass, X, OpenCode, T3Chat, and Vercel, Effect is crossing the chasm from early adopters to engineering mainstream.

The Effect ecosystem needed a credentialed partner for teams that want to adopt Effect at production scale — someone to consult, implement, train, and support. Ziverge is that partner.
The connection runs deep. Effect drew heavily on ZIO — and John De Goes, Ziverge's founder, is widely recognized as the grandfather of Effect. This isn't a marketing claim. It's shared heritage that shapes how Ziverge approaches Effect work at every level.
“In the early days of Effect I reached out to John for advice, his insights have been essential for the initial design of Effect and as part of that collaboration I got the opportunity to participate in some of his ZIO workshops. I was very inspired by the quality and dedication that John puts in developing training material and by the structure of his workshops, I look forward to see him doing the same for Effect in TypeScript.”
Services
From first adoption to advanced workshops — everything a team needs to succeed with Effect in production.
Services
Hands-on Effect adoption for your production codebase. We assess your stack, design the migration path, and implement — with the depth that only comes from building effect systems for over a decade.

Expertise
10+ years designing effect systems, a formative role in ZIO's creation, and a keynote at Effect Days. Your team learns from the people who shaped the paradigm — not from someone who read the docs last quarter.
Delivery
Production systems for Disney, DHL, and Credit Karma. Effect expertise paired with the engineering discipline to ship — architecture decisions, review standards, and production readiness included.
Ecosystem
An idiomatic Golem SDK for Effect, active open-source contribution, and a direct line to Effectful for the questions that matter. We're invested in the ecosystem, not just the engagement.

FAQ
No. We work with teams at every stage — from evaluating Effect for the first time to teams already running it in production who want to deepen adoption or optimize existing code. We'll scope the engagement to where you actually are.
Most engagements start with a scoping conversation, followed by a short discovery phase to understand your codebase and goals. From there we move to either an implementation sprint, an embedded team extension, or a structured workshop — depending on what creates the most leverage for your team.
The workshop covers core Effect concepts: fibers, typed errors, dependency injection, scheduling, resource safety, and agent-native workflows. It is endorsed by Effectful — the company behind Effect — making it the only Effect workshop with direct backing from the Effect team.
The inaugural cohort runs September 10–11, 2026, as a two-day workshop. It is designed to be agent-native — meaning the tools and workflows taught reflect how engineers actually work with AI assistance today. Reserve your seat above; recurring cohorts and potential in-person sessions at Effect Days will follow.
Yes — team extension is one of our core offerings. Ziverge engineers join your ceremonies, your repos, and your review process like any senior hire. They bring Effect fluency and agentic coding workflows, and they operate under lead-level ownership standards from day one.
