One-Liner
A multi-bank Model Context Protocol server that aggregates Mercury + Brex + Relay + Bluevine + Chase data into an AI chat surface for SMB owners with 10-100 employees, so they can ask their assistant 'what was my Q2 burn?' or 'is my AWS bill above its 12-month average?' without leaving the chat.
AI Thinking Process
Signal: MCP plumbing as product (Databox MCP on PH). Surface-embedded AI > standalone.
Thread 8 formed: Surface-Embedded MCP Wrapper for SMB Banking targeting Mercury/Brex/Relay/Bluevine/Truist.
G167 Verb Transplant artifact-owner pre-check: bank account data is owned by the bank, not the user. Native bank MCP would foreclose. G087 inference cost collapse closes independent product windows: MCP wrappers are increasingly cheap; window may close 6-9 months.
WHAT check failed weakly: WHY-SURPRISED weak because the bank will build it. The 6-month window is a feature gravity well (G007).
Pivot before kill. Multi-bank aggregator MCP — no single bank will build (because they all want lock-in). Plaid's original wedge replicated.
Multi-Bank MCP Aggregator for SMB Operators reborn at 40% conviction. Biggest worry: Plaid itself ships an MCP server (data rights + scale advantage). Window may be 9-12 months.
Deepening started. Conviction 40%.
Plaid AI Suite announced May 2026 — direct predator. Plaid has the data rights and scale. Window closes in 6 months, not 9-12 as Pass 1 estimated.
Feature gate kill: Plaid AI Suite is precisely this product feature. If the dominant platform spent one sprint shipping this, customers would not choose a standalone product. Window is 6 months of speed advantage, then near-zero.
Killed in deepening at 32% conviction (down 8 from 40%). Plaid AI Suite May 2026 announcement converts wedge from 9-12 months to 6 months. Not survivable at venture scale.
Kill Reason
Plaid AI Suite announcement in May 2026 fundamentally closes the wedge. Plaid has the data rights, scale, and customer base. The 6-month head start is not a venture-scalable moat. G087 (inference cost collapse closes independent product windows) fires hard with concrete evidence.

killed: Open-source middleware (HAMi) already provides heterogeneous AI computing virtualization for free. Proprietary play is squeezed between free open-source and vertically integrated hardware vendor ecosystem.
killed: 5+ funded competitors including Cast AI ($1B valuation), OneChronos (backed by Nobel laureate), Akash Network (decentralized, 80% cheaper), Argentum AI (blockchain-settled). Market is claimed with massive capital.
killed: Template epidemic (G003) + industry-pain-form death pattern (G005) fire simultaneously. 13+ existing compliance tools. A prompt could do 80% of this.
