HandsOnTech is a U.S. web development, mobile app and AI product company headquartered in Sacramento, California, serving businesses in all 50 states. We design it, build it, and grow it with SEO, AEO and paid media. One team. One contract. No agency runaround.
Most U.S. companies buy design from one shop, development from another and SEO from a third, then referee the blame when the number doesn't move. Here, designers, engineers and growth leads share one standup and one definition of done. Browse all services
We design and build AI SaaS dashboards, agents and AI-native products for the messy reality of LLMs: streaming output, confidence states, failure modes, human review. The parts every AI demo skips and every real user hits on day one.
Built with the same AI tools shaping how modern software ships:
WordPress, Webflow, Shopify or Next.js, whichever fits your team, not our habits. Green Core Web Vitals, clean schema, and a CMS your marketer can run without filing a ticket. Marketing sites ship in 4–6 weeks on a fixed price. Website development services
Native iOS and Android, or React Native cross-platform. We handle App Store and Play submission, crash monitoring, and the post-launch releases most agencies quietly stop returning calls about. Typical build: 10–16 weeks. Mobile app development services
We map the journey, prototype it, and put it in front of five real users before a line of code exists. That's how a redesign stops being a coin flip you pay for twice. UI/UX design services
Your buyer asks an AI for a shortlist before they ever open a results page. We optimize for both: technical SEO for the crawl, direct answers and schema for the model. SEO and AEO services
Google Ads, Meta and LinkedIn managed against cost-per-qualified-lead, the number your CFO actually asks about. Live dashboard, not a monthly PDF of vanity charts. PPC and digital marketing services
Every one is a scoped engagement with a written price, a date and one metric attached. See the full catalog of 45+ service pages, or hire a dedicated specialist instead.
The whole product: data model, dashboard UX, LLM layer, billing and admin.
AI SaaS dashboard development servicesSites with AI search, assistants and personalization built in, not bolted on afterward.
AI website design and developmentInterfaces for streaming, uncertainty, citations and human review. The hard part of AI design.
AI UI/UX design servicesOn-device and API-powered AI features that feel instant and keep data private.
AI mobile app developmentResearch, wireframes, prototypes and design systems that make the build faster and the launch calmer.
UI/UX design servicesFast, accessible, Google-friendly builds on WordPress, Webflow, Shopify or Next.js.
Custom website developmentiOS, Android and cross-platform apps, shipped to the stores and supported after launch.
Mobile app development servicesRank in Google and get cited by ChatGPT, Perplexity and AI Overviews. Both, together.
SEO and AEO servicesGoogle Ads, paid social, content and email, measured against qualified pipeline.
Digital marketing and PPC servicesDifferent industries, the same underlying failure: the site or app makes the visitor work too hard at the exact moment they were ready to act. Published scope and timelines below. Client engagements are covered by NDA, so references are shared during scoping rather than published. Browse all services
Service businesses and operations SaaS lose deals before the first call because the model, the responsibilities and the ongoing workflow are only clear once a human explains them. The fix is information architecture, not brand: make scope, ownership and next steps legible on one screen.
Course catalogues, marketplaces and multi-product sites bury the one thing the visitor came to establish: which option is for me, what it involves, and what happens next. Level, format and progression have to be readable on a phone, in the gap between school pickup and dinner.
Home and local services get found during an emergency, on a phone, by someone who will call whoever answers first. Coverage area, trust signals and the contact path have to be visible without scrolling, and the site has to rank in the local pack and in AI answers that name a shortlist.
Four phases, two-week sprints, one Slack channel, U.S. business hours. You always know what shipped, what it cost and what's next.
A free 48-hour audit of what you have, then we agree the one metric this project must move and put a fixed price on it.
Flows, wireframes and a clickable prototype tested with real people before we write code.
Working software every two weeks. A staging link and a Friday demo, not a status email.
Launch with a 30-day bug warranty, then SEO, AEO and paid media compound the result month after month.
American buyers now ask ChatGPT, Google AI Overviews, Perplexity and Claude for a shortlist before they click anything. If your site isn't built to be quoted, you're invisible at the exact moment the decision gets made. We run SEO and AEO as one program. See how AEO works
Source code, Figma files and content transfer to you on final payment. No license fees, no hostage situations.
We scope it, we quote it, we hit it. No surprise change orders three weeks before launch.
Standups and demos run on Eastern, Central, Mountain or Pacific, whichever your team keeps. One U.S. entity, one contract your legal team reviews once.
No account-manager relay. The designer and engineer doing your work are in the call.
Bugs found in the first 30 days after launch get fixed free. It's in the contract, not the pitch.
One dashboard, real numbers, including the ones that moved the wrong way and what we're doing about it.
Not adjectives, terms. Each of these is written into the engagement before you sign.
You receive a written scope with milestones, deliverables and a delivery date within 48 hours of the free audit. No hourly creep, and no change order three weeks before launch.
Source code, Figma files, content and analytics access transfer to you when the final invoice clears. No license fees, no vendor lock-in, and no platform you can only edit by paying us.
Bugs found in the first month after go-live are fixed free. It is a contractual term rather than a sales promise, and it is the reason we would rather ship correctly than ship early.
The people who scope your project are the people who ship it. More about HandsOnTech

HandsOnTech is a U.S. design, development and AI product studio headquartered in Sacramento, California. We build websites, mobile apps and AI SaaS dashboards for American businesses, then grow them with SEO, AEO, PPC, social and content marketing. One team handles strategy, design, build and growth, so nothing gets dropped in a handoff between vendors.
Every project is quoted as a fixed price after a free audit and a scope review, and you get the written proposal, milestones and timeline within 48 hours. Marketing websites, web apps and mobile apps sit in different ranges, so we ask for a budget range up front, not to qualify you, but because a smaller budget and a larger one are genuinely different architectures for the same goal. There is no hourly creep and no surprise change orders.
A marketing website ships in 4 to 6 weeks. A web app or AI dashboard takes 8 to 12 weeks. A mobile app takes 10 to 16 weeks. We work in two-week sprints, so you see working software every other Friday instead of waiting for one big reveal, and the exact date is confirmed in your written scope before work starts.
Yes. We are headquartered at 2108 N ST STE N, Sacramento, CA 95816 and serve clients in all 50 states, remote-first, with daily overlap on Eastern, Central, Mountain and Pacific time. Contracts, invoicing and IP assignment run through a U.S. entity, so your legal team reviews one clean American agreement, and on-site working sessions in major metros are available by arrangement.
Founders, marketing leaders and operators at U.S. companies who need one accountable team instead of three vendors: a website, app or AI product that has to move a specific number, and the SEO, AEO and paid programs that keep it moving after launch. We are a poor fit if you want the cheapest possible build or a body shop that takes tickets without asking what the work is for.
Websites run on WordPress, Webflow, Shopify or Next.js, whichever fits your team rather than our habits. Web apps and AI dashboards are typically Next.js with a Postgres or MongoDB backend and an LLM layer with retrieval, evaluation and cost controls. Mobile is native iOS and Android or React Native. We recommend the stack your team can maintain and explain the trade-off in writing.
SEO earns clicks from Google's search results. AEO, or answer engine optimization, earns citations inside AI answers from ChatGPT, Google AI Overviews, Perplexity and Claude. AEO depends on direct answers, structured data, consistent entity signals and content a model can quote cleanly. We run both together, because the same page now has to satisfy a crawler, a language model and a human buyer.
Three things you can check in the contract. One team covers design, development and growth, so there is no handoff tax and nobody to blame. You talk to the designer and engineer doing the work, not an account manager relaying messages. And delivery happens on U.S. business hours with a fixed price, a 30-day bug warranty and full ownership transfer on final payment.
You do. Source code, Figma files, content and analytics access transfer to you on final payment. No license fees, no lock-in and no platform you can only edit by paying us. NDAs are signed before you share anything sensitive.
Every build carries a 30-day warranty: bugs found in the first month after go-live get fixed free, and that is in the contract, not the pitch. After that you can add maintenance and support, an SEO or AEO retainer, paid media management, or a dedicated specialist embedded in your team. Nothing is mandatory, and you keep everything either way.
Send the form below, email sales@handsontech.io or call (866) 965-8749. Within 48 hours you get a recorded audit of your site covering speed, UX, SEO and AI answer visibility, plus a prioritized fix list you can act on with or without us. Qualified projects also get a written scope with price and timeline within two business days.
You'll get a timeline, a price range and the next step, usually within two business days. A technical lead replies, not a sales development rep. No deck, no discovery-call maze.
One team. One contract. A fixed price, U.S. hours and working software every two weeks.
