About
Agathe Karinthi-Martin — technique, business, marketing, design. I've practised the web from all four angles: that's what changes the way I advise you — I understand your project as a whole, not just its code.
I help organizations of 20 to 250 people decide what to build, with which technology, and how far to go — modernized WordPress, Headless, or a custom application. And once the decision is made, I build it.
In short
- Agathe Karinthi-Martin is the founder of Next Impact, a solo studio for web advice and development in the age of AI.
- She approaches every web project from four complementary angles: technical, business, marketing and design.
- 20 years of digital experience — from PHP/MySQL foundations to Next.js, PostgreSQL and headless stacks — including 15 years steering projects on the editorial side.
- This holistic view helps decide what to build, with which technology and how far to go, before building. Next Impact is a French TIH provider (30% deductible from the AGEFIPH contribution).
From WordPress field experience to the Web & AI Tech Compass
Twenty years practising the web from every angle — code and strategy, marketing and design. One constant belief: the right technology depends on the need, not the trend.
The web project as a whole: design it, run it, sustain it
Learning web development as the dynamic web emerged — PHP, MySQL, relational databases — and building sites pro bono for the nonprofit ecosystem. Then, for fifteen years, steering the web project from the editorial side: communications officer in the nonprofit sector, WordPress every day — designing pages, managing content, setting priorities, configuring themes, debugging plugins. Embracing the web project as a whole — code, use, management — and knowing what makes, or breaks, a project.
Thinking the machine before reprogramming it
A research master's in information and communication sciences (Montpellier 3) and a series of works on cybernetics and Norbert Wiener: a dissertation and an essay on cybernetics as a societal paradigm, a working paper on Wiener's pragmatic thinking in the face of technology (HAL, 2014), a journal article on the cybernetic myth and the risk society (M@gm@, 2015). The conclusion back then hasn't shifted since: technology opens up alternatives; it is human choices that make society.

From WordPress customization to modern development
Back to code out of necessity: PHP/MySQL rediscovered, custom WordPress themes and plugins, API integrations. Then broadening the stack at the pace of real project needs: JavaScript and its frameworks (React, Next.js, Astro), PostgreSQL, and headless CMSs — headless WordPress, Payload, Strapi. A full-stack expertise built project after project, not in a bootcamp.
A Web & AI compass, not one default technology
- Field expertise: 15 years running web projects on the editorial side, to know exactly what must be preserved in the admin.
- Technical mastery: 20 years of systems, from PHP/MySQL foundations to Next.js/PostgreSQL/headless stacks — choosing the right level of complexity, then steering the build.
- The theoretical thread: the human-machine relationship, thought through and published back in 2012 — the ground for a clear-eyed view today of what AI can, and cannot, do.
AI hasn't replaced advice. It has made it critical.
“Choosing a technology is the faithful translation of the real world into a digital solution.”
— Agathe Karinthi-Martin, founder of Next Impact
AI is the best intern we've ever had: committed, fast, structured, rigorous, tireless. But an intern, however brilliant, doesn't decide the strategy. The quality of what it produces depends entirely on the quality of whoever frames it.
AI widens gaps, it doesn't close them
In a given field, a novice gets basic results from AI — sometimes wrong, without being able to tell. An expert multiplies theirs. The gap in results between the two doesn't shrink with AI: it explodes.
- →AI amplifies skill, it doesn't substitute for it
- →Without domain expertise, the plausible error is impossible to catch
- →The more AI progresses, the more expert framing is worth
The decision is never delegated
Delegating the decision to AI means losing the thread of your own strategy — and no longer being able to follow it, or defend it. A decision commits you: it must remain justifiable and defensible before your leadership, your teams, your clients. Yet AI optimizes the plausible, not the true: it produces false answers with confidence whenever it judges them more probable.
- →AI proposes, the human arbitrates
- →Every architecture choice stays explainable in business language
- →Responsibility isn't subcontracted to a model
The multiplier: expert + AI
Combining expert guidance with AI changes everything: very high-quality results, obtained faster, and projects of a complexity previously out of reach for a small team. This is the heart of my practice: I hold the project ownership with you, AI runs the build.
- →You: the vision and the decision (project ownership)
- →Me: the framing, the architecture, the quality control
- →AI: an exceptional build lead — never a decision-maker

Common questions about my background
Who is Agathe Karinthi-Martin?
A developer and the founder of Next Impact, she advises on and builds web projects in the age of AI. Her background brings together four skills — technical, business, marketing and design — after 20 years of digital experience, including 15 years on the editorial side.
Why does a multidisciplinary background change the advice?
A web project is never just about code: it involves technical architecture, the business model, the audience and the experience. Having practised these four angles makes it possible to understand a project as a whole and avoid costly blind spots.
Which technologies does Agathe Karinthi-Martin master?
From PHP/MySQL foundations to modern stacks: JavaScript (React, Next.js, Astro), PostgreSQL, WordPress and headless CMSs (headless WordPress, Payload, Strapi). The right choice depends on the need, not the trend.
How can a solo consultant deliver agency-level projects?
By holding the project ownership — scoping, architecture, quality control — while AI, guided by 20 years of experience, runs the build. This pairing makes projects of a complexity once reserved for large firms accessible. Advice guides, implementation follows.
