Your agentic SaaS
in production in 4 days.

With your team — and they stay autonomous.

You've got an agentic product to ship and it's stalling. Not for lack of talent — for lack of method and agentic experience. That gap costs you time and money while competitors move.

Founder Sprint — four days to get you to autonomy. I put your AI-native foundation in place, productionizing your coding agents included. Then we settle the business decisions to bake in immediately, with no six-month discovery phase.

Pierre Tomasina, founder of dev3o

Every piece of software is becoming agentic.

After 15 years on systems from finance to SaaS startups, this is what I see everywhere — while most teams still build like it's 2021. I build them AI-native from the foundation, a discipline I call Vibe Engineering.

AI is now intelligent enough to run complex tasks end to end, unsupervised. We call these agentic systems. I help you build them natively into your own platform: not an AI feature bolted onto a static app, but agents doing the real work, at the core of the product.

This shift puts the whole software industry in question. Value no longer lives in features — an agent clones those overnight. It lives in sharp vertical expertise and method: what you do better than anyone, encoded into agents that run and scale it 24/7. The winners are the ones starting now, not the ones waiting for it to be obvious.

Founder Sprint: your agentic SaaS in production, in days.

Your team has an agentic product to ship and it's stalling. Not for lack of talent — for lack of method and focus. The Founder Sprint is the accelerator that unblocks it, and makes you autonomous.

Four intense days. You leave with the product moving and the method to keep going.

We do it together, in three moves:

  1. 1

    The foundation

    I lay the AI-native agentic foundation of your product, with RED — license included.

  2. 2

    The decisions

    Together we settle the calls that keep dragging and blocking the ship.

  3. 3

    The autonomy

    Your team leaves able to continue without me.

What you're actually buying

A product that finally moves.

What really costs you is every month it doesn't ship.

You leave with

  • An agentic SaaS in production
  • A working agentic dev environment
  • A clear roadmap
  • A follow-up call

Then the incubator, to stay at the edge.

4 days · RED license included

No team to build it yet? I bootstrap your MVP on an AI-native foundation, then hand off to your freelancers — or point you to a partner I trust. On quote.

They went AI-Native.

Founder Sprint · Done-With-You

2 months of deadlock, cleared in 48h

A SaaS team already mature on AI workflows, caught off guard by the agentic shift: two months stalling on their v2 with freelancers, for lower-quality output. In 48h, we laid the agentic foundations of the v2, production-ready — the primitives of an agentic SaaS in their own brand. Product features still had to be wired in, but on a solid base instead of a site that wasn't moving.

RED · external technical validation

When the prospect's CTO writes your pitch for you

The team at an AI media studio evaluated RED for their new SaaS. The verdict, from their own technical memo: RED's reference architecture is “nearly exact” to their product, and the SaaS base represents “3 to 4 months of development saved.” Proof written by the client, not by me.

After the Sprint: the dev3o incubator.

Agentic engineering moves every month: what worked yesterday is already outdated. The incubator is the continuity. Your teams apply the good practices daily and stay at the edge, long after the bootstrap — with or without me in the code.

  • Agentic Engineering course

    5 modules, 41 lessons, continuously updated. The method and the production discipline of the 90/10: specs, setup, security, system design.

  • Community + live sessions

    Monthly live sessions with replays (the key lessons, in action) and Gems of the Week.

  • Group office hours

    Collective pair-debugging and architecture reviews. For intensive one-on-one support, that's the dedicated retainer, on request.

  • Aporia soon

    Your product's memory: decisions, tensions, and the drift between what you wanted and what the agents produced. Early access and member pricing reserved for subscribers.

One seat for you, or the whole team.

RED isn't part of the incubator: the tool stays separate from the knowledge. The RED license is included only in the Founder Sprint.

The wall every agentic founder hits.

You've got the domain expertise and the product in your head. Then comes the plumbing — the part that has nothing to do with your idea, yet stands between you and production: auth, billing, multi-tenancy, the agent engine… 3 to 4 months before the first real feature.

RED is that wall, already cleared. The hardest primitives of an agentic SaaS, built and battle-tested across multiple projects:

  • Auth & multi-tenant

    Email, OAuth, passkeys, 2FA. Isolated organizations: members, billing, audit, API keys.

  • Built-in billing

    Stripe: plans, entitlements, metered usage, checkout. You charge from day one.

  • Agent engine

    Typed declarative tools, background tasks, results that flow back into the thread. Your agents do the work.

  • Reactive core

    State updates in the UI in real time, no polling. Built for collaborative workspaces.

  • Admin & audit

    Global admin portal, audit trail on sensitive actions. Serious B2B from the start.

  • Multi-provider AI

    AI SDK v6, multi-provider routing, Anthropic native. Swap models without a rewrite.

A team was building their AI-augmented writing SaaS on their own engine. They had the domain expertise — what they lacked were the primitives to take it to the next level. After evaluating RED, their own CTO's verdict:

“RED's reference architecture is “nearly exact” to our product. The SaaS base represents 3 to 4 months of development saved.”
CTO of an AI media studio — technical evaluation memo

AI writes 90% of the code. The last 10% — specs, agentic setup, security, system design — decides whether the product succeeds. RED covers the 90%. I take the 10% that actually counts.

I install it on day one of the Sprint: the days we spend together go straight to your product, never the plumbing.

What I build.

Proof in code: what I actually use and ship — public, open source, battle-tested daily. Not slides.

  • RED starter kit

    AI-native reactive backend, now a public starter kit. The engine behind every Sprint.

  • sandbox-shell open source

    Credential protection for agentic workflows. A malicious package doesn't read your keys.

  • Aporia soon

    Shared product memory for teams building in the age of agents.

devx-plugins open source

Claude Code plugins forged in daily use — opinionated, minimal, honest. Not vibe-coded experiments.

  • devx-qa a senior review pass as a skill: architecture analysis, code review, appsec, and React/skill audits.
  • secrets-guard blocks the agent from reading sensitive files — 70+ credential patterns, so a stray prompt never leaks your keys.

An agentic SaaS that won't ship?

We fix that together, in days — not months.
