How it works

From question to decision
in four steps

Define what you're looking for. OpportunityOS does the research, scores the evidence, and tells you whether the opportunity is worth pursuing.

01
Define your goal
Tell OpportunityOS what you're looking for — a market, a geography, a type of business, a budget. Or bring a specific idea you want to validate in a new market.
~2 minutes
02
Agent researches
AI agents scan Reddit, G2, Flippa, Product Hunt, search data, and acquisition marketplaces. Real signals — not training data. Every source is logged.
Agentic pipeline
03
Evidence scored
Raw signals are structured into evidence items and scored across 8 dimensions: market demand, competitor weakness, reachability, willingness to pay, and more.
8 validation gates
04
GO / NO-GO report
You receive a ranked report with a clear recommendation, supporting evidence, identified risks, and suggested next steps. A negative result is as valuable as a positive one.

The founder passed. The opportunity was real — the agent correctly identified a genuine market gap with zero competitors. But at €0.6–2.0M realistic ARR, the market was too small for the founder's ambitions. Decision made in under 15 minutes. Without OpportunityOS, the same conclusion would have required days of manual research across Spanish app stores, industry databases, and competitor analysis — followed by the same answer.

Why not just use ChatGPT

Generic AI gives you ideas.
We give you evidence.

The difference isn't the answer — it's what's behind it.

ChatGPT / Claude
× Works from training data, not live market signals. Doesn't know what's on Flippa today.
× Produces plausible-sounding answers without traceable evidence.
× Every conversation starts from zero. Nothing accumulates.
× No structured scoring. Can't compare two opportunities on equal terms.
× No rejection criteria. Everything sounds like it could work.
OpportunityOS
✓ Live data from Reddit, G2, Flippa, Product Hunt. Real signals, not memory.
✓ Every recommendation traces back to specific sources, timestamps, and scores.
✓ Persistent evidence store. Each run builds on the last.
✓ 8 scored dimensions. Opportunities are comparable and rankable.
✓ GO / NO-GO with evidence. A well-reasoned no saves more than a vague yes.
