Saddle Up AI is a digital marketing agency built for the trades. We work exclusively with MEP contractors (plumbing, HVAC, and electrical companies) and help them turn online searches into booked calls. What we do: - AI-built websites designed to turn visitors into calls - Google Ads and Local Services Ads (LSA) - Meta (Facebook & Instagram) Ads - SEO and local search visibility Contractors are great at what they do, but most don't have time to run their own marketing. We handle it end to end so owners can focus on running jobs while we keep the phone ringing. We're a remote team and we're growing. If you like working with small business owners, selling real results, and getting rewarded for performance, we'd love to hear from you.

Ohana Helps is building the technology layer for the home-services industry. We’re starting with handyman services, but this is much more than a handyman marketplace. We’re building a platform for both customers and independent service professionals: guided quoting, real appointment booking, payments, service history, scheduling, customer management, marketing tools, reviews, promotions, vendor business tools, AI, voice technology, automation, and more. There is significantly more technology behind Ohana than most people would expect. We already have a substantial product and codebase in place. Now I’m looking for the right CTO / Technical Cofounder to help turn it into a category-defining company. I’m not looking for someone who simply wants a developer job. I want a partner who wants to build, ship, lead, solve hard problems, recruit a strong engineering team, and take real ownership of the technology. Over the next 12–18 months, we need to strengthen the existing platform, dramatically improve the customer and vendor UI/UX, launch major new features, expand our AI and automation capabilities, improve infrastructure and reliability, and prepare the product for expansion throughout the U.S. Our goal is to build quickly enough and prove enough growth to put Ohana on a Series A trajectory next year. This is a genuine founding-level opportunity with up to 25% equity, depending on experience, commitment, role, and final structure. We are currently pre-funding, so this is not a salaried CTO opportunity today. It is for someone who wants meaningful ownership and wants to help build the company, not simply work for one. I bring the industry experience, operating knowledge, business model, customer understanding, and vision. I’m looking for the technical partner who can help me build the technology and team capable of taking Ohana nationwide. If your reaction is, “I want to help build that,” we should talk.

We are building conversational AI agents for businesses.
