Latest opportunities

Fintech infrastructure

Invoicing API for Vertical SaaS Platforms

A developer-first invoicing API that lets vertical SaaS platforms embed compliant, white-labeled invoicing for their end customers — tax handling, numbering rules, PDF rendering, dunning, and payment-link generation behind a handful of endpoints. Sold usage-based to platforms serving trades, clinics, and studios that currently bolt together PDFs and payment links by hand.

Marketplace

Marketplace for Vetted Vertical AI Agent Templates

A two-sided marketplace where automation consultants sell production-tested agent templates (intake bots, quoting agents, follow-up sequences) for specific industries, and SMBs buy them pre-configured for their stack. Takes a transaction cut plus a hosting subscription — the "theme marketplace" model applied to working agents rather than code.

Consumer SaaS

AI Personal Admin Agent for Busy Households

A consumer agent that handles household administration end-to-end: disputing bills, cancelling subscriptions, booking appointments, chasing insurance claims, and renewing documents — acting via email and phone with user approval gates. Sold as a monthly membership to dual-income households who currently let this work pile up.

B2B SaaS

AI Regulatory Compliance Monitoring Agent

A monitoring agent that watches regulatory feeds, agency guidance, and enforcement actions for one regulated niche (e.g., cosmetics labeling, med-spa advertising, or crypto marketing), then maps changes to a client's actual policies and flags concrete gaps. Replaces the "junior associate reads the Federal Register" workflow at a fraction of the cost.

B2B SaaS

AI Bookkeeping Agent for Service Businesses

An autonomous bookkeeping agent that categorizes transactions, chases receipts over email, reconciles accounts monthly, and produces accountant-ready books for service businesses (agencies, trades, clinics). Positioned between DIY QuickBooks neglect and a $400+/month human bookkeeper, with a human-review layer on low-confidence entries.

B2B SaaS

AI SDR Agent for Niche B2B Verticals

An outbound prospecting agent that researches accounts, drafts genuinely personalized first-touch emails, and manages follow-up sequences for one narrow vertical (e.g., logistics SaaS or dental-practice software) instead of trying to be a horizontal SDR replacement. Sells to founders and first sales hires who cannot yet justify an SDR salary.

Ten signals, one rubric

Every opportunity is assessed on the same ten qualitative factors, and every one is graded on a single scale: Favorable, Mixed, or Unfavorable. The two measured market dimensions — Competitive Intensity and Disruption Risk — keep their Low/Medium/High reading visible alongside the grade (low intensity or risk reads Favorable). No fake precision, no black-box scores — just consistent editorial judgment you can compare across opportunities.

SignalWhat it measures
Marketing-channel feasibilityHow accessible and proven are the channels needed to reach customers?
Gross-margin potentialWhat is left after direct delivery costs at scale?
Time to first revenueHow quickly can this business realistically produce its first paying customer?
Stickiness / retentionOnce acquired, how likely are customers to stay and keep paying?
Build / technical complexityHow difficult is the product to build and maintain?
Founder interaction / service postureHow much ongoing founder-led service does the model demand?
ScalabilityHow well does the model grow without proportional cost or headcount?
Customer EconomicsUnit economics headline: margin, payback period, and LTV shape.
Competitive IntensityHow many credible direct competitors currently operate in this space? Measured Low / Medium / High — low intensity grades Favorable.
Disruption RiskLikelihood that technology, regulation, or market shifts could erode this opportunity. Measured Low / Medium / High — low risk grades Favorable.
