Role 01 · AI Engineering
Multi-Persona Investor Engine
Five investors. One pitch. Every objection before the real room.
Context

Jeff Pro is JustStartUP's AI co-founder, shipped inside the Startup Suite. Its Investor mode lets founders pitch and get grilled. Today a single model plays every investor and the personas blur into each other. We're rebuilding it as a Supervisor / Worker orchestration: one pitch, five isolated investor agents evaluating in parallel, one synthesised verdict.

The Five Investor Agents
The Contrarian

Funds only 0-to-1 paradigm shifts. Judges the founder's core secret and monopoly potential; rejects incremental, horizontal plays.

The Mathematician

Cash flow, margins, CAC, downside protection. Never validates burn-to-scale; pushes royalty-style deal structures.

The Operator

Sales cure all. Punishes outsourced core competencies, overhead and fluff; demands gross margin and lean execution.

The Brand Builder

Gut instinct and mass-market appeal. Judges D2C narrative, packaging and founder-market fit; ignores deep-tech complexity.

The Scaler

Business is a street fight. Transaction volume, penetration speed, habit formation; attacks corporate jargon on sight.

Requirements
  • Supervisor agent that normalises the raw pitch (text or JSON) and fans it out to all five workers concurrently; no shared context between workers, so evaluation logic never cross-contaminates.
  • Five worker agents, each with a modular system prompt (identity, evaluation criteria, output rules) plus global constraints: no filler openers, no congratulations, verdict first.
  • Schema-enforced output per worker: verdict (Yes / No), primary_critique (1 sentence), actionable_demand (1 command), plus a 0–10 score per evaluation criterion.
  • Weighted scoring in code, not in the prompt: criterion scores × persona weights computed server-side, so verdicts are consistent and auditable.
  • Persona voice lock: hidden few-shot mock pitches per agent. Evaluate whether per-agent temperature / logit-bias tuning is supported on the chosen model; if not, enforce vocabulary through prompt + few-shot. Recommend the model with evidence.
  • Synthesis engine: Supervisor reads all five verdicts; on a split decision it generates a consensus summary naming who would fund, who would walk, and why.
  • Matrix View in the Jeff Pro UI: five persona cards (verdict, critique, demand, score) with the synthesis on top. Mobile-first, matching the existing Jeff Pro interface.
  • Cost control: each pitch = 6 model calls. Per-user daily pitch cap, timeouts, and graceful partial results if a worker fails.
  • Plugs into the existing Jeff Pro backend: auth, Startup Suite gating, session memory, and PDF / Excel export must cover Investor mode results.

Role 02 · Growth
Business Development Lead
100 paid Jeff Pro users in 60 days. Straight commission.
Mission

Own Jeff Pro user acquisition end-to-end: identify stuck early-stage founders, run first-touch outreach with Jeff Free as the hook (never lead with paid), and convert to the Startup Suite (Jeff Pro included) at $18/month.

Requirements
  • Prospect across X, Reddit, LinkedIn, Instagram using our existing lead-qualification framework (provided on onboarding).
  • First-touch must offer Jeff Free before any mention of Jeff Pro or JustStartUP.
  • Weekly pipeline report: leads contacted, demos, conversions.
  • Comply with each platform's anti-spam norms — brand integrity over volume.
Compensation

30% commission on every Jeff Pro conversion you close, paid monthly. Plus certificate, LOR, and conditional full-time offer on target completion.

  • Formal written employment offer — role title, responsibilities, and salary range defined in writing, contingent on seed round close.
  • Letter of Recommendation on JustStartUP letterhead.
  • Verified digital certificate of contribution.
