Haithem Kchaou
Founder of Callab AI, AI voice agents for on-prem telephony stack.
Company
Haithem Kchaou is listed as a founder of Callab AI. 58% of the $400B call center industry runs on on-prem phone systems, and until now bringing AI voice automation to them meant ripping out their entire infrastructure first. That's the largest unserved segment in the market. Callab AI connects directly to legacy PBX systems like Avaya, Cisco UCM, and Mitel, and automates up to 70% of call volume with zero migration needed. We plug into these environments without requiring a rip-and-replace. We serve clients across three continents, including brands like Dunkin Donuts.

for a startup to succeed, there needs to be speed (which correlates with long working hours) & the right direction.

we need a startup positivity movement on x for founders not adding 1M ARR every 2 days. ( just like body positivity on IG) "your sales pipeline doens't define your worth" "every ARR is high and beautiful in its own way." "Arr is just a social construct invented by VCs"...
