AI agent systems for plumbers, electricians, HVAC shops, and general contractors. Missed-call booking, estimate follow-up, memberships, reviews, and crew briefings. Live at https://agentichacks.ai.

AgenticHacks is trades-only: plumbers, electricians, HVAC shops, and general contractors or remodelers. Each hack is a build guide with cited pain stats, a workflow, a trigger, data sources, numbered steps with branches, tools, a rough monthly cost, difficulty, setup time, an ROI formula, and caveats. Figures come from the October 15, 2026 research brief. Vendor stats are labeled. Dollar tool prices that were not in the brief are marked unverified. Grok Voice (grok-voice-3.0, alias grok-voice-latest) is the recommended voice layer on the missed-call and speed-to-lead hacks, at xAI's published $0.08/min plus $0.004 per text input; Retell and Vapi stay alternatives. Grok Speech to Text ($0.10/hr REST, $0.20/hr streaming) is the recommended transcription on the change-order hack. Those xAI rates are cited to https://docs.x.ai/developers/pricing and are not marked unverified. /for/realtors redirects to the home page. Sponsor names in the ticker are fictional.

Founding sponsorship is $299/week for the first 3 slots (a logo in the site-wide ticker, plus a mention in each daily hacks email that week). The price rises after each sale. The audience is owners of plumbing, electrical, HVAC, and remodeling companies. Book a slot by emailing AgenticHacks@gmail.com with the subject "AgenticHacks sponsorship".
