About
Built by a small team for the
small businesses tired of missing calls.
Human Add AI was started in 2025 to give small service businesses the same 24/7 phone coverage that enterprise call centers take for granted. The team builds each AI voice agent by hand for the specific vertical (HVAC, plumbing, dental, legal) so the conversation sounds like a senior receptionist, not a chatbot. The platform powers thousands of conversations per month across fifty US metros.
Human Add AI started in 2023 with a simple observation: most small businesses lose revenue not because their service is bad, but because the phone rings while everyone is already busy serving customers. We built a 24/7 AI voice receptionist that answers, qualifies, and books , on the first ring, every ring.

Founder · Human Add AI
I started Human Add AI because I watched too many small businesses lose revenue from missed calls , not because the work wasn’t there, but because the people doing the work couldn’t pick up the phone.
We build on Retell AI’s low-latency voice infrastructure and layer on a custom-trained knowledge base for each business , their services, their pricing, their scheduling rules, their tone. The AI sounds human, handles unlimited concurrent calls, and books appointments straight into the customer’s CRM. No per-minute fees. No contracts. Live the day you sign up.
“If your phone rings 100 times today and you only answer 70 of them, we’re the cheapest way to capture the other 30.”
The story
In 2023 we started building voice AI agents one customer at a time , a dental practice that needed appointment rescheduling without a front desk on weekends, an HVAC company drowning in after-hours emergency calls, a plaintiff law firm whose paralegals were taking intake calls instead of working cases.
Each one taught us the same lesson: the AI has to know the business better than a temp would after a week of shadowing. Generic call scripts and one-size FAQ bots fail the moment a real customer asks something specific. So we built a deeper customization layer , an AI that scrapes the customer’s website, ingests their pricing and scheduling rules, and trains on their actual voice and brand , and wrapped it in a 5-minute self-serve setup.
Today Human Add AI runs in 13 industries across the United States. Our customers include solo trades, multi-location practices, and a few enterprise deployments where the AI handles thousands of calls a day. We ship pricing, the comparison page, and the demo number publicly because we believe small business owners can decide on their own whether the product fits.
What we believe
Transparent pricing.
Pricing is on the website. No “contact us for a quote.” $497/$997/$1,997 with a $10 trial activation. If you can read the number you can decide whether the product fits.
No contracts.
Month-to-month. If we’re not driving more bookings than we cost, you cancel. We don’t lock anyone in.
Transfer to human.
When the AI hits its knowledge edge, it transfers , not pretends. The fastest way to lose a customer is to fake an answer.
Real ownership.
Each customer gets a dedicated phone number, full call recordings, transcripts, and lead data. Your data, exportable, anytime.

Plans and pricing
If you are reading about the people behind Human Add AI because you want a phone answered while you work, the plan that suits you depends on how many calls your business takes. A one-line owner can begin on Starter at $497 a month (up to 200 calls, one assistant, one business number), while a busier team that wants unlimited calls and up to 3 assistants would look at Professional at $997 a month, with Enterprise from $1,997 a month. Because we are a Massachusetts company, you can hear the AI for yourself before choosing: the 7-day free trial has a $10 activation fee credited to your first bill, and a 30-day money-back guarantee backs it, with no annual contracts. Compare tiers on the pricing page or call the demo line at (617) 812-5251 to talk with it live.
The operator-side decision math in 2026
Service-business operators making purchase decisions on phone infrastructure in 2026 typically run the math three ways before committing. Way one: monthly recurring cost compared to monthly recovered missed-call revenue, where the platform earns its keep inside the first week for any business handling more than about 100 inbound calls per month. Way two: total cost of ownership over a 12-month horizon including outbound usage, integration setup time, and the operator time spent on phone qualification that the platform now handles automatically. Way three: opportunity cost of not installing the platform, calculated as missed-call revenue lost during the months of delay while the operator evaluates options.
All three calculations land in the same place for almost every service-business profile: a single-location operator with 100 to 1,500 monthly calls and an average ticket size of $250 or more breaks even on the platform inside the first week and runs net positive for every week after that. The exception is a business with very low call volume (under 50 calls per month) or very low ticket size (under $100 per booked job), where the recovered-revenue math gets thinner.
For every other profile, the answer the math gives is to launch fast and let the platform compound. The same-day go-live means the operator can be live by the end of the week and start recovering missed-call revenue immediately. Every week of delay costs real money in lost bookings, and the operator can always cancel later if the platform underperforms the recovered-revenue model.
