Five autonomous agents.
One lean team.
Built to maintain.
Your post asked the right question first — which agent platform fits your use case best, and why. This proposal answers it directly, then walks the architecture, the multi-agent orchestration, and the phased rollout from one trial agent to five working in coordination.
Three constraints that shape every decision.
Three things drive the platform choice and the build architecture for a 3-founder firm running a multi-region pipeline. Get any of them wrong and the agents become a liability instead of leverage.
Ops don't scale with headcount
12+ lender relationships, 30+ brokers, 6 regions. The bottleneck isn't strategy — it's the orchestration of repetitive, high-attention-to-detail tasks. That's exactly the work agents do well, and exactly why your scope is correct.
Platform choice locks in the cost curve
Pick the wrong agent framework and you're either paying for orchestration you don't need, or fighting visual-tool limits when you outgrow them. This is the most consequential decision in the project — which is why you flagged it as question one.
Founders need to maintain it
A 3-person team can't run a black-box agent system. Every workflow needs to be readable, debuggable, and editable without calling the developer back. That requirement rules out several of the platforms you researched — and points cleanly at one.
Click each platform. The recommended pick has a star.
You named seven platforms in your post. I've shipped production agents against most of them. Here's the honest comparison — strengths, weaknesses, and the verdict for your specific use case at your specific scale.
Same criteria. All seven platforms.

n8n as orchestrator. Claude as the brain.
Hover any node in the diagram to inspect what it does and why it's there. The architecture is intentionally simple — fewer moving parts means fewer things to maintain.
Same broker outreach template. Three regions. Zero rewrites.
This is what Claude does inside the Broker Outreach agent: take your master template plus the broker's region, company, and personalized outreach angle, and produce an email that reads like you wrote it. Click between brokers to see it shift live.
Hi Carlos,
I lead an aviation finance advisory firm in Miami — we specialize in cross-border business jet acquisitions across the US and Latin America, with 12 active lender relationships.
I've been watching GlobalAir's deal flow into the São Paulo market this year — particularly the mid-cabin transactions back to US-based owners. That's exactly the corridor where our LatAm cross-border financing expertise tends to add the most value for brokers.
Would you have 20 minutes for an intro call next week? I'd love to understand what your typical buyer profile looks like and where financing tends to slow your deals down.
Best,
[Your name]
One trial. Four follow-ons. One orchestrator.
Build the trial first. Validate against real broker outreach for one to two weeks. If it earns its place, agents two through five roll out one per week — each pulling reusable pieces from the trial's n8n workflows and Claude prompt library.
Broker Outreach & CRM
The trial agent — 30+ brokers across 6 regions
- Broker list ingested from Excel/CSV into Notion with region + outreach angle fields
- Personalized initial outreach via Gmail — founder approval gate before first send per broker
- 7 / 14 / 30-day follow-up cadence; reply detection halts the sequence automatically
- Open + reply tracking, Calendly link routed on positive response, weekly pipeline report
Client Document Chaser
Financing closes faster when docs land sooner
- Document checklist auto-sent to financing clients per deal
- 3-day follow-up cadence on outstanding items, reply detection halts cadence
- Notion tracking against a master checklist per deal
- Auto-flag when a package is complete — handoff signal to downstream agents
Lender Routing Assistant
12 lenders, ranked per deal, with reasoning
- Deal parameters ingested via Notion form — model, year, price, buyer profile, region
- Claude ranks all 12 lenders against your eligibility criteria with written reasoning per ranking
- Draft outreach emails generated per eligible lender — paste-ready or auto-send with approval
- All outputs reviewable in Notion before any send goes out
Marketing & Content Engine
LinkedIn, newsletter, conference prep
- LinkedIn post generation from deal news and industry signals in your founder voice
- Weekly email newsletter drafts pulling from active pipeline + market commentary
- Conference prep materials — briefing docs, target lists, talking points per event
- Always reviewed before publish — quality stays in your hands, volume goes up
Operations Coordinator
The orchestrator — agents talk to agents, founders see one view
- Cross-agent handoff orchestration — broker positive response triggers deal creation, which triggers Doc Chaser + Lender Router automatically
- Status monitoring across all 4 prior agents with failure alerts routed to founders in real time
- Consolidated weekly operations report — pipeline state across the entire agent fleet on one page
- Idempotent handoffs — duplicate triggers are detected and merged, no double-firing on the same broker reply
How the agents talk to each other.
Agent 5 isn't a separate intelligence — it's the connective tissue. When Agent 1 detects a positive broker response, the orchestrator creates a deal record, triggers Agent 2 to start chasing documents, and triggers Agent 3 to rank lenders. Founders get one consolidated view of everything moving.
What the agents cost to run.
You asked for the ongoing maintenance and cost profile. Move the sliders to model your specific outreach volume — and watch how it shifts.
Trial first. Validate. Then scale.
The trial agent runs the gauntlet for 1–2 weeks of real broker outreach before any other agent gets built. Once validated, the remaining four roll out at one per week. Total project window: 7 weeks end-to-end.
Fixed-fee by phase. No surprises.
Trial fixed at the top of your stated range — the platform recommendation doc is part of the deliverable and that thinking compounds across every subsequent agent. Phases 2–5 quoted on the back end so you only commit after the trial earns its place.
Broker Outreach agent built, deployed, and ready for your 1–2 week validation. Platform recommendation doc delivered Day 1.
- Broker list ingestion + Notion CRM structure
- Personalized initial outreach + approval workflow
- 7 / 14 / 30-day follow-up cadence with reply detection

Top of your stated $800–1,500 range. Each agent reuses ~60% of the trial's n8n workflows and Claude prompt patterns.
- Agent 2 · Client Document Chaser
- Agent 3 · Lender Routing Assistant
- Agent 4 · Marketing & Content Engine
- Agent 5 · Operations Coordinator
- Documentation per agent + handoff Loom
- Optional retainer for tuning + new use cases
Let's walk the platform recommendation together.
A 30-minute call where I share my screen, walk through the platform tradeoffs against the 6 you researched, and confirm trial agent scope. I'll bring n8n open in one tab and a sample broker outreach workflow ready to demo. Ready to start immediately on selection.
