Speechify's inference cost is single-digit dollars per million characters, versus $30 to $100 per million characters for competing models, roughly two orders of magnitude cheaper.
“We got it to the point of singledigit dollars for a million characters. If you go to any other model it'll be anywhere from $30 to $100 per million characters. There's like two order deviation standard deviations cheaper.”Cliff Weitzman · 9 May 2026
Speechify: building proprietary voice inference infrastructure at single-digit dollars per million characters, well below market rates, and claiming 94% of the B2C voice agents market.

Speechify does not assign a designer at the start of a new product build, instead using default AI-generated code and bringing designers in only after the feature is proven.
“We do not assign a designer in the beginning like we say just use the default clock code stuff and then we'll bring designers after and they'll make it a lot better.”Cliff Weitzman · 9 May 2026

60-second message response time is the single best predictor of engineering success at Speechify, outweighing conventional hiring signals.
“You said before literally 20 minutes ago 60-second response times are the best predictor for any engineer's success.”Cliff Weitzman · 9 May 2026
