About Maxime

Your business already runs on WhatsApp: your leads, your clients, your team. What's missing is the system to capture it all and act on it.

I design and operate AI systems on WhatsApp that are in production today:

- An AI chief of staff for an American investment fund ($80M in assets): every WhatsApp conversation captured, CRM built automatically, daily brief to associates.
- An AI client assistant for a business coach: onboarding, automation of forms to Notion, follow-ups, 100% hands-off.
- The growth stack for my own online publishing house: subscriptions, referrals, and revenue reporting driven by agents.

My method: every project starts with a fixed-price Automation Audit. I map your processes, identify where hours and leads are slipping away, and provide you with a prioritized and costed plan. If we build together, 100% of the audit fee is credited towards the build.

Stack: Claude / GPT agents, WhatsApp (Official API & Baileys), Node.js, Python, Supabase/Postgres, Notion, Stripe, data encrypted at rest.

I respond with a concrete plan for YOUR situation, not a template.
