The Comparison
Message testing at startup speed.
TestSynthiaThe Old Way
B2B message testing is prohibitively expensive.
The Price Barrier
Wynter charges $500-1,000 per message test. For early-stage teams, that's a week's worth of ad spend or a month of tools — just to test one headline.
Slow Turnaround
Even after paying premium prices, you wait 24-48 hours for results. When you're iterating on launch copy, that delay kills momentum.
Limited Volume
At $500 per test, you can only afford to test your top 2-3 variations. What if the 4th variation was the winner? You'll never know because you couldn't afford to test it.
