Quick Answer
A comparison of revenue or other metrics between the same period across two years.
Year-over-year growth (YoY) is the comparison of a metric (most commonly revenue) between the current period and the same period one year earlier, expressed as a percentage increase or decrease. YoY is the standard growth metric in venture capital because it controls for seasonality and provides a comparable baseline across different time periods. A company reporting $5M ARR this month versus $2M ARR the same month last year has 150% YoY growth. Early-stage investors typically expect 100%+ YoY revenue growth for Series A-stage companies, while growth-stage benchmarks vary by sector and company size.
In Practice
CloudKitchen, a restaurant technology platform, presented its growth metrics to Series B investors. Their MoM growth had been volatile — ranging from -5% to +25% — making it hard to assess the underlying trajectory. But their YoY numbers told a clear story: Q1 revenue grew from $1.8M to $4.2M (133% YoY), Q2 from $2.1M to $5.1M (143% YoY), and Q3 from $2.4M to $5.8M (142% YoY).
The consistent YoY growth rate, despite monthly volatility driven by restaurant industry seasonality, gave investors confidence that CloudKitchen had sustainable momentum. The YoY framing also revealed something MoM growth obscured: the company was accelerating on an absolute dollar basis (adding $2.4M, $3.0M, and $3.4M in incremental annual revenue each quarter), even though the percentage growth rate appeared flat. CloudKitchen closed a $30M Series B at a 20x ARR multiple.
Why It Matters
For founders, YoY growth is the metric that most directly determines fundraising success and valuation. Investors are trained to evaluate companies through a YoY lens, and presenting growth in this format makes it easy for them to benchmark your performance against portfolio companies and market comparables. Founders should track YoY growth across all key metrics and understand which ones are accelerating, decelerating, or holding steady.
For investors, YoY growth is the primary input into growth-adjusted valuation models. A company growing 150% YoY commands a very different multiple than one growing 40% YoY, even if their current revenue is identical. YoY trends also reveal the sustainability of growth: consistent YoY growth over multiple periods suggests durable demand, while volatile YoY numbers may indicate one-time tailwinds or inconsistent execution.
VC Beast Take
YoY growth is the lingua franca of venture capital, and like any widely used metric, it gets manipulated. The most common trick is cherry-picking the comparison period. A company that had a weak Q2 last year (maybe due to churn or a delayed product launch) can show astronomical YoY growth in the current Q2 simply because the baseline was artificially depressed. Smart investors always look at the absolute numbers alongside the percentage growth and examine multiple periods to ensure the YoY figures reflect genuine trajectory rather than base-rate effects.
The more subtle YoY insight is understanding the difference between percentage growth and absolute growth. A company growing from $1M to $3M (200% YoY) is adding $2M in incremental revenue. A company growing from $20M to $30M (50% YoY) is adding $10M. The percentage growth favors the smaller company, but the absolute growth favors the larger one. The best growth analysis considers both dimensions, because venture-scale outcomes require large absolute numbers, not just impressive percentages.
