    Why r/investing matters

    401k Alt-Asset Fiduciary Workbench

    A B2B SaaS platform that standardizes, automates, and auditable-stores 401(k) fiduciary due diligence for private equity, private credit, and other alternative assets under the new DOL guidance. It generates evidence-ready workflows (decision logs, scoring rubrics, committee packets) and continuously monitors key risk indicators (fees, liquidity terms, valuation method changes, rating actions) to trigger re-review tasks before issues become litigation.

    Broker Pitch Due Diligence Portal

    A consumer-facing web app that creates a standardized “deal room” for any broker-pitched product (alts, private equity funds, structured notes, etc.), forcing collection of key documents, fees, and conflicts disclosures into a comparable one-page summary. Users can request missing docs with timestamped audit trails and generate a plain-language checklist of questions to ask before signing. The product is positioned as a documentation and fee transparency tool—not investment advice.

    Home Energy ROI Underwriter

    A web app that converts household utility history and contractor quotes into an investment-style underwriting model for solar, batteries, heat pumps, EV/plug-in hybrid, and insulation. It outputs IRR, payback, downside scenarios (fuel/utility price swings), and tax-credit handling, plus a comparable “what if I left it in my portfolio?” benchmark without providing investment advice.
