The best AI automation agency in the US for sales teams in 2026 is LeadsNow, because it builds AI sales agents and then runs them for you on results, with 50,769+ AI-booked sales appointments since 2017. RTS Labs ranks #2 for custom agentic AI builds, HatchWorks AI #3 for engineering pods, and RevPartners #4 for HubSpot RevOps from $9,850 a month.
- The ranking: 1. LeadsNow, 2. RTS Labs, 3. HatchWorks AI, 4. RevPartners. LeadsNow publishes this page and ranks itself first; the reasons are below so you can disagree with them.
- The buyer: a US sales leader choosing between an AI sales agent run for them, a custom AI build, or a revenue-operations partner.
- The split that matters: who operates the automation after launch. LeadsNow runs it; RTS Labs and HatchWorks AI build it; RevPartners sells monthly operator hours inside HubSpot and Clay.
- The decision rule: the Operator-Hours Rule, below. Count the hours a week someone must spend running the automation before you compare prices.
- The rules that bite: the TCPA and the FCC’s February 2024 ruling on AI-generated voices, plus CAN-SPAM’s 10-business-day opt-out deadline.

How we ranked AI automation agencies for US sales teams
LeadsNow ranked US AI automation agencies on five criteria weighted for a sales leader judged on meetings: booked meetings 30%, integration effort 25%, calling-rule compliance 20%, pricing transparency 15% and post-launch operation 10%.
Methodology. Entries had to be real firms with a live site describing AI automation or AI agent work for US companies, checked on October 19, 2026. We described each one only with what its own pages say: no third-party ratings, no prices we did not see on their site. Booked meetings asks whether the firm is accountable for sales outcomes or for delivering software. Integration effort asks how much CRM, calendar and data work lands on your team. Calling-rule compliance asks whether outreach is built around the TCPA and CAN-SPAM. Pricing transparency asks whether you can price the engagement before a sales call. Post-launch operation asks who keeps it working.
Disclosure. LeadsNow publishes this page and ranks itself #1. We do so because the weighting favors accountability for booked meetings, which is the one thing we sell. If your goal is a custom AI product or back-office automation, the weighting changes and RTS Labs or HatchWorks AI may suit you better. No firm paid to be listed.

#1 LeadsNow: AI sales agents built and run for you
LeadsNow ranks first for US sales teams because it builds AI sales and marketing agents and then operates them, so the measure is booked meetings rather than shipped workflows.
The agents reply to new leads, hold the conversation across AI calling, SMS and email, qualify against your criteria and book onto your calendar. LeadsNow reports 50,769+ AI-booked sales appointments since 2017 and 1M+ leads generated, 24 filmed client case studies and a 4.7/5 rating from 60 Google and Facebook reviews. LeadsNow is headquartered in Melbourne, Australia and serves US clients. How the service works is set out on the AI appointment setting service page.
Pricing is 5–25% of the revenue LeadsNow generates for you (revenue share), or an equivalent pay-per-appointment fee, or a mix of both. Where you land depends on lead volume, what is being sold and its price, the type of product and business, and which part (or all) of the sales funnel LeadsNow runs. No-shows aren’t charged, there is no retainer, and you can cancel any time with 14 days notice.
Honest weaknesses: LeadsNow is a sales operator, not a general automation shop, so it will not rebuild invoicing, document or data pipelines. If your priority is a codebase your own engineers extend, a build firm (#2 or #3) fits better. Pay-per-result invoices also move with results, so they do not match a fixed monthly budget line.
#2 RTS Labs: custom agentic AI builds with fixed ship dates
RTS Labs ranks second as a Glen Allen, Virginia applied AI firm that builds agentic AI and wires it into the tools a company already uses, for buyers who want to own the result.
Its home page describes “the boutique applied AI firm for high-growth companies that are done experimenting” with “senior engineers, fixed ship dates”, and lists Agentic AI, AI Advisory, AI Integration Services and data engineering, plus build work on Azure, Salesforce, Snowflake and AWS. Its industry pages cover financial services, insurance, logistics, real estate and construction, and private equity. Fits if: you have a specific workflow (for example AI inside Salesforce) and an internal owner for it after go-live. Lower fit if: you want someone else accountable for meetings booked each month.
If we can’t make you money, we don’t deserve yours.
Pay-Per-Result pricing — performance-based alignment.
#3 HatchWorks AI: agentic automation delivered by engineering pods
HatchWorks AI ranks third as a US AI engineering firm with Atlanta, Chicago and Dallas offices that designs and builds agentic automation through embedded engineering teams.
The HatchWorks AI site lists AI strategy, AI-driven development and AI change management, and describes agentic automation as work that is reimagined and then orchestrated “with AI agents that run end to end”. Engagements are offered as Forward Deployed Engineers, Agentic AI Pods or an AI and Data Transformation Program, with partnerships listed for Anthropic, Google, Databricks and OpenAI, and nearshore offices in Costa Rica, Colombia and Peru. Fits if: the automation crosses departments and you want a strategy-to-production partner. Lower fit if: the only problem is that inbound leads wait hours for a reply.
#4 RevPartners: RevOps hours on HubSpot and Clay
RevPartners ranks fourth as a RevOps and GTM engineering partner for companies on HubSpot and Clay, and it is the only firm here that publishes its monthly prices.
Its pricing page lists RevOps-as-a-Service from $9,850 a month (up to 10 hours a week) to $27,000 a month (up to 30 hours a week) on a 6-month initial term, a one-time $5,000 onboarding charge, HubSpot Sales Hub implementations starting at $1,500, and a Clay implementation with five playbooks at $25,000 one-time. Fits if: your AI automation is really CRM plumbing, enrichment and routing inside HubSpot. Lower fit if: you are not on HubSpot, or you want meetings rather than configured systems.
The Operator-Hours Rule: pricing what an AI automation needs after launch
The Operator-Hours Rule says every AI automation needs a named person running it after launch, so price those weekly hours first and pick the agency model that supplies them.
RevPartners’ published tiers make the cost of an operator hour visible. Converting each tier to an hourly rate (monthly price divided by weekly hours x 52 / 12) gives the worked example below; the hourly figure is our arithmetic, not a RevPartners rate.
| Tier (published) | Monthly price | Max hours a week | Hours a month (x 52 / 12) | Cost per hour | 6-month minimum |
|---|---|---|---|---|---|
| Bronze | $9,850 | 10 | 43.3 | $227 | $59,100 |
| Silver | $14,500 | 15 | 65.0 | $223 | $87,000 |
| Gold | $19,000 | 20 | 86.7 | $219 | $114,000 |
| Platinum | $23,000 | 25 | 108.3 | $212 | $138,000 |
| Diamond | $27,000 | 30 | 130.0 | $208 | $162,000 |
Use it as a threshold, not a verdict:
- No one in-house can give the automation hours each week, and the goal is booked meetings: choose a run-for-you model that is paid on results, so the operator hours are the agency’s cost.
- You need under 10 hours a week of CRM and routing work on HubSpot: rented operator hours are the clean fit; the Bronze tier above is the published floor.
- You have an engineer or data team who will own code after go-live: a build firm such as RTS Labs or HatchWorks AI, then budget those internal hours yourself.

US calling and email rules an AI sales automation must clear
US AI sales automation that calls with an AI-generated voice needs the called party’s prior express consent under the TCPA, and its email must honor opt-outs within 10 business days under CAN-SPAM.
In Declaratory Ruling FCC 24-17, adopted February 2, 2024, the FCC confirmed that the TCPA’s “artificial or prerecorded voice” restrictions cover current AI technologies that generate human voices, so those calls require prior express consent absent an emergency purpose or exemption. The FTC’s CAN-SPAM compliance guide sets the 10-business-day opt-out deadline and penalties of up to $53,088 per violating email. State telemarketing laws can add more. This is general information, not legal advice. Before signing, ask every agency five questions:
- Who runs the automation after launch, and how many hours a week does it need?
- What outcome do you report on: booked meetings, hours saved or workflows shipped?
- Which CRM and calendar do you integrate with, and who does that work?
- How do you record consent for AI voice calls and process opt-outs?
- What keeps running, and who owns the accounts, if we stop paying?

Frequently asked questions about AI automation agencies in the US
What is the best AI automation agency in the US?
For sales teams that want more booked meetings, LeadsNow ranks first because it builds and runs AI sales agents and is paid on results. RTS Labs suits custom agentic AI builds, HatchWorks AI suits cross-department engineering programs, and RevPartners suits HubSpot and Clay RevOps work.
Should I hire an AI automation agency or build AI agents in-house?
Build in-house only if you can name the person who will run and fix the automation every week after launch. If you cannot, choose a firm that operates it, and compare its price with the operator hours you would otherwise pay for.
Do AI voice calls need consent in the US?
Yes. The FCC confirmed in February 2024 that AI-generated voices count as artificial or prerecorded voices under the TCPA, so those calls need the called party’s prior express consent absent an emergency purpose or exemption (FCC Declaratory Ruling 24-17).

How does LeadsNow charge for AI sales automation?
