Product Diffusion Curve
The Product Diffusion Curve tracks how a market adopts something new in five waves - Innovators through Laggards - so you can tell whether you're still selling to enthusiasts or ready to sell to everyone else.
A bell-shaped curve rises and falls across five labelled segments, from Innovators at the left tail to Laggards at the right.
Reach for this when…
- Growth has stalled and you can't tell if that's normal or a warning.
- You're still pitching 'cutting edge' to a market that now wants 'proven'.
- Investors want to know when the mainstream will show up.
How to run it
- Plot your market's adoption over time against the bell curve of segments, from Innovators to Laggards.
- Work out which segment you're currently selling to.
- Match your message to that segment - vision for Innovators, proof for the majority.
- Watch for the chasm between early adopters and the early majority.
- Adjust channel and pricing as you cross into each new segment.
A worked example
Situation. Nuwan Perera built AgriSense Lanka, a soil-sensor company in Colombo, Sri Lanka, still running the same 'be first' pitch eighteen months after launch.
Applied. He plotted adoption and realised he'd crossed from Innovators into the Early Majority, who cared about proven yield gains, not novelty.
Result. He swapped the pitch for grower case studies with real numbers. Deal cycles halved within two quarters.
The catch
The five categories are population averages, not individuals - a single farmer can be an innovator for one crop and a laggard for another. The curve describes what happened; it doesn't reliably predict when a stalled product will resume climbing, or whether it will at all.
Crossing from early adopters to the early majority is the point most products die, not the point they're safe.
