These are the 8 agencies in the directory closest to The Kiln on category, industries, stack, team size and starting price, most similar first.
The Kiln ranks #4 in AI Sales Agencies. It publishes a starting price of $10,000. Its best fit, in our words: Companies with $10,000 a month to commit to GTM architecture and CRM transformation, and no objection to the firm now sitting inside a larger marketing services group.
Best forBuyers who want both a revenue system and people to work it, and who will specify in the contract how much of each they are paying for.
Also ranked in AI Sales Agencies; works with SaaS companies, healthcare organizations and financial services firms; both build on Clay and Salesforce.
FullFunnel is a genuine hybrid, and that is neither a criticism nor an accident: a company that needs a system built and has nobody to run it can get both from one vendor here, on a one-month commitment that is unusually short for this tier.
The main cautionSells white-labeled SDR and AE teams next to its engineering work, with Clutch putting 15% of the business in sales outsourcing, so a buyer expecting a system can be sold sellers

Pricing
From $5k$5,000+/month with a one-month minimum (Clay partner directory and HubSpot's directory), the shortest commitment among Clay's top-tier partners
Best forSaaS revenue teams that need the lead-to-opportunity path, data model and reporting rebuilt inside Salesforce, with no outbound sending involved.
Also ranked in AI Sales Agencies; works with SaaS companies, healthcare organizations and financial services firms; both build on Clay and Salesforce.
This is the systems end of the category. Go Nimbly builds and repairs the machinery inside a client's CRM and leaves it there, and the roster behind that claim is one of the two strongest here.
The main cautionTwo Clutch reviews for a firm founded in 2013, so the public evidence is almost entirely self-published

Pricing
From $5k$5,000+/month with a three-month minimum (self-declared on Clay's partner directory); Clutch instead shows a $50,000+ minimum project size and $150-$199/hr
Best forCompanies that need SDRs working next month and want the CRM, workflow and reporting behind them built by the same firm.
Also ranked in AI Sales Agencies; works with SaaS companies and healthcare organizations; both build on Clay and Salesforce.
If the problem is that there is nobody to make the calls, demandDrive is a reasonable answer, and a better one than most staffing-shaped vendors because it can also build the CRM, workflow and reporting layer the sellers work inside. That combination, plus HubSpot Diamond status and operating history back to 2011, makes it the best evidenced firm in the outsourced group here.
The main cautionThe core business is recruiting, training and renting out SDRs, so the AI framing overstates how much of delivery is software

51-200
Pricing
From $5k$5,000+ minimum project size (Clutch-displayed); nothing published on its own site
Best forTeams that want GTM engineering and outbound run as an ongoing subscription and do not need to own the system at the end of it.
Also ranked in AI Sales Agencies; works with SaaS companies and healthcare organizations; both build on Clay and Salesforce.
The engineering menu is credible and the tooling is more serious than the category average, with Snowflake and n8n sitting alongside the usual Clay and Apollo stack.
The main cautionPublishes no statement that the client owns what gets built, unlike its closest peers here

RevPartners is the clearest buy in this category for a company that wants a revenue system rather than rented sellers.

Frontal is the cleanest answer in this ranking to the question a buyer should be asking, which is whether they end up owning anything.
The main cautionEvery published result is the agency's own unaudited figure, and its Clutch profile carries no reviews

Martal is the most explicitly headcount based firm in this ranking, and that is a description rather than a complaint.
