Hello! There are two spots left Saturday at ▍
[ 04 / Work ]

Each project learns a trade.

02HR · Field RecruitingRafaReactSupabaseAgents IA

An advertising platform built for recruiting. Rafa turns a job opening into a Meta and Google campaign, produces the creatives, publishes a careers page and scores every application. The loop closes on HR data: it optimizes for interviews attended, not clicks.

03Sales · Multichannel OutreachBeaufixeNext.jsSupabaseClaude

B2B outreach software where four named AI agents do the work: the Strategist sets the course, the Scout finds and scores prospects, the Quill writes the messages, the Lookout reads the replies. Email, LinkedIn and WhatsApp in a single sequence, connected to a CRM and a visual pipeline.

04AI · Expert AgentsForticheNext.jsPostgreSQLClaude

A platform where people who know their trade (a coach, a lawyer, a chef, an accountant) put their method into an AI agent and publish it. You ask your question, the agent answers the way they would: it makes a call instead of listing five options. Subscribers pay the author every month.

05Family · Co-parentingNOUSNext.jsSupabaseTailwind

A mobile matching app for co-parenting projects. Profile and values, matching on the questions that matter (education, organization, finances, life plans), parenting quizzes and a completion gauge to move forward calmly through a journey built on trust.

06Finance · Family officeWealth reportingPythonNode.jsOpenAI

A reporting engine for a family office. It reads monthly statements from banks and insurers (PDF), fills in the reporting workbook, reconciles every total and produces a client report of about twenty pages. It learns portfolio by portfolio, from the months done by hand.

07Finance · Mergers & AcquisitionsNovaltNext.jsTailwindSupabase

Premium showcase website and digital tools for an M&A advisory firm. Transaction presentations, prospect qualification, secure data room. AI agent for incoming file pre-scoring.

08Real Estate · PropTechLoqrReactNode.jsPostgreSQL

Real estate infrastructure management platform. Technical intervention tracking, maintenance planning, multi-site dashboard. AI agent for automatic technician dispatch and emergency prioritization.

09Tech · DataAlgo MangoReactNode.jsPostgreSQL

Custom algorithmic platform. Personalized recommendation engine, intelligent scoring, data flow automation. AI agent for continuous performance analysis and optimization.

[ How it runs ]

Four steps, with dates.

The same sequence for a custom tool as for an agent. Every step comes with a duration announced before we start, not discovered along the way.

  1. Scoping

    We look at your business, your users, your constraints. You leave with a scoping document that becomes the project’s reference. Nothing starts before you sign off.

    1 week
  2. Mockups & architecture

    Clickable screens, data model, stack decisions. You see exactly what we are going to build before the first line of code.

    2 to 4 weeks
  3. Build in sprints

    One or two-week cycles, a demo at the end of each. You test, you validate, we adjust. No three-month tunnel with no news.

    4 to 12 weeks
  4. Production & handover

    Deployment, monitoring, training for your team. We stay reachable for the first thirty days in production, fixes included.

    30 days included

[ 05 / The studio ]

We prefer doing two things well over doing ten poorly. Zero outsourcing: we code every line ourselves, we configure every agent ourselves, and we say no to projects we couldn't deliver.

[ The frame ]

What we don’t do.

Saying no early costs everyone less than a project we would have done badly. Here is where we stop.

  • We don’t put AI everywhere

    Plenty of tasks are solved by a simple automation, or by changing a process. When that is the case, we say so — even when it shrinks the invoice.

  • We don’t subcontract

    Every line is written by one of the two of us. No junior on loan, no relay agency, no code we would be discovering at the same time as you.

  • We don’t run ten projects at once

    Two serious builds at a time, no more. If the schedule doesn’t work, you hear it in the first conversation rather than in the third month.

  • We don’t lock you in

    The code is yours, it runs on your infrastructure, and we train your team to take it over. Leaving has to stay possible without buying anything back from us.
