Cleiton Sena — Public Wiki¶
AI-Native Revenue Architect · Fractional · B2B SaaS · 🇧🇷 🇪🇸 🇩🇪
I design and build AI agent departments for B2B SaaS revenue teams. Currently fractional at Soilytix — running revenue ops + building the agent system that automates them, on a managed-SaaS-only stack (Anthropic + Gemini + Langfuse). EU agritech soil intelligence. €0→€600k ARR plan.
Soilytix is one client + my live case study. I have capacity for 1-2 additional B2B SaaS engagements. If you're building or scaling a revenue function and want to add an AI agent layer, let's talk.
This wiki is the public-safe subset of my internal "second brain" (Karpathy pattern). What's here is what's safe + interesting to share. The Soilytix-confidential parts (pipeline, pricing, customer specifics) stay private.
What's here¶
Concepts — frameworks for AI-native operations¶
- Agent Management Architecture — 8 layers of agent management decomposed, Soilytix track + Personal track, managed-SaaS-only Stack C decision

Work with me¶
Currently engaged 3 days/week with Soilytix. Capacity for 1-2 additional B2B SaaS fractional engagements (typically 2 days/week, 60-90 day initial scope). Best fit:
- B2B SaaS post-PMF, scaling revenue ops
- Want to add an AI agent layer (not "AI tools") to revenue function
- EU residency / GDPR compliance matters
- Have ICP clarity — execution is the gap, not strategy
