How Many Startup Ideas Are Actually Viable? The 2026 Benchmark (39,952 Ideas Scored)
The median startup idea founders submitted to our free validator scored 5/10. Only ~5% — about 1 in 20 — scored 7 or above. 22.8% scored below 5/10 — the score display's red band.
Based on 39,952 idea-descriptions founders submitted to DimeADozen (a random sample of the 100,000+ submitted — 40,000 drawn, 99.9% parsed cleanly), each scored on one instrument: our free 4-dimension validator, 1–10. For context, a comparable published idea-check benchmark covers ~4,000. Updated 2026; re-scored as more ideas come in.
How many startup ideas are actually viable?
The validator doesn't label ideas "viable" — it scores each 1–10 and flags a red band below 5, so the honest answer is the distribution: across 39,952 founder-submitted ideas in 2026, the median scored 5, 22.8% fell in the red band (below 5), and only ~5% scored 7+. Most land squarely in the middle (5–6).
What percentage of startup ideas score in the bottom band?
22.8% of the 39,952 ideas (9,118) scored below 5/10 — the validator's red band. 76.9% landed in the middle band (5–7, amber), and just 0.30% (120 ideas) scored 8–10 (green).
What is the average startup idea viability score?
Across 39,952 ideas, the median viability score was 5 and the mean 5.11 on a 1–10 scale (p25 = 5, p75 = 6).
What percentage of startup ideas are actually strong?
Only ~5% — about 1 in 20 — scored 7 or higher. Just 0.30% (120 of 39,952) scored 8 or above. A strong score is the exception, not the rule.

Score-by-score (1→10): 518 · 684 · 1,175 · 6,741 · 15,422 · 13,429 · 1,863 · 96 · 23 · 1. The mass sits at 5 (38.6%) and 6 (33.6%).
Why so many ideas score middling — and what it means
The median idea scores 5/10, with the mass at 5–6 and only ~5% scoring 7+ — a middling score is the norm, not a red flag on your specific idea. A 5/10 isn't a verdict that your idea is doomed; it's a map of what an independent read flags to fix, before you commit a year to building.
How we scored 39,952 startup ideas (methodology)
- Corpus: 39,952 idea-descriptions founders submitted — a random sample of the 100,000+ (40,000 drawn, 99.9% parsed); descriptions on file, length/detail vary; a self-selected idea-stage population, not "all startup ideas."
- One instrument, un-floored: the same free 4-dimension validator, native 1–10 raw scale — not the normalized number on a purchased report.
- Threshold: "below 5" is the validator's own live display band (red pill); the UI shows a number + color, no verdict-word, so we apply none. Full distribution shown so the finding holds regardless of any cut.
- Purity control: we also scored the 479 raw one-liner inputs typed directly into the scorer — central tendency consistent (median 5, mean ~5.0–5.1 both); below-5 runs ~5pp higher on raw one-liners (27.8% vs 22.8%), i.e. more-elaborated descriptions score marginally higher; the median finding is robust to input style.
- Aggregate + anonymized · 2026 · re-scored as more come in.
- Cross-sectional snapshot: ideas scored as submitted, at one point in time — a base-rate distribution, not a measure of how any idea changes with iteration. No claim about why the ~5% score high or how any score evolves.
Why we publish honest odds when others won't
Most tools make money when you decide to build — so they're built to keep you optimistic. We make money whether the answer is build or don't, so we've no reason to inflate the odds. If the median idea scores 5/10 and only ~5% score 7+, a founder deserves to see the real distribution before sinking a year in.
