Why Bad Tech Kills Startups

Real data. Real consequences. Don't let this be your story.

63% Tech Debt Rate

Most startups suffer significant tech debt from skipping quality practices

42% Time Lost

Developers waste nearly half their time managing debt instead of shipping features

$1.52 Trillion Cost

Annual economic impact of technical debt in the US economy alone

10-100x Cost Multiplier

Fixing bad architecture later costs exponentially more than building it right

30-50% Valuation Drop

Weak tech foundations destroy due diligence and tank startup valuations

70% User Abandonment

Slow, buggy systems drive users away in seconds—bad tech kills growth
