Prajwal Kumar is the founder and CEO of HulloDesk. He built HulloDesk after a firsthand experience that most entrepreneurs recognize immediately: calling 14 different trade contractors and reaching only 2 of them.
That experience revealed a massive, systemic problem — trade contractors lose revenue every day not because they lack skills, but because they cannot answer the phone while on a job. HulloDesk is the solution: an AI voice agent that answers every call, qualifies every lead, and books jobs 24/7 without a human receptionist.
HulloDesk is based in San Francisco, CA and serves HVAC, plumbing, electrical, roofing, and other trade contractors across the United States.
