The Kiln review
Builds and runs it · Brooklyn, New York, United States
The Kiln builds go-to-market systems in Clay. Its homepage describes a team of automation experts, data scientists and early Clay employees, working across three areas: sales and outbound, marketing and growth, and RevOps. Most of what it publishes is about architecture, meaning how accounts get scored, how data gets cleaned and how a signal reaches a rep, rather than meeting counts.
Since 6 January 2026 it has been owned by 2X, a marketing services firm backed by Recognize Partners and Insight Partners. The announcement, linked from a banner still marked new on The Kiln's homepage, says 2X brings nearly 1,300 staff across the US, Malaysia and the Philippines. It names co-founders Patrick Spychalski and Mathias Powell and says nothing about prices, terms or staffing for existing clients.
The work is part build, part run. Some case studies describe The Kiln launching and scaling campaigns itself: email and LinkedIn outreach for T-ROC, and a three-day Dreamforce campaign in Smartlead for Clientell. Others describe systems handed over, with Daxko's team trained to own and operate what was built and a Bunker testimonial crediting detailed SOPs left for use after the engagement.
The evidence is concrete. Ten case studies name the client and quote a named person, and several describe the build in enough detail to judge it: AdRoll's five shared Clay functions feeding more than ten signals, Crescendo's 1-to-100 scoring model run across 50,000 companies, and the Salesforce checks that cut accidental prospecting of Daxko's own customers.
Nothing commercial is published. There is no price, no rate, no minimum and no term, and the way in is a 30-minute call booked through the contact page. The homepage says its GTM engineers work with only a few clients at a time, which is a statement about capacity rather than a price signal.
Our scorecard
Scored 1 to 5 on how specific each commitment is on the company's own site, from 5 for published and specific to 1 for nothing said. It does not score the quality of the work, which only clients can see.
The Kiln publishes deep build detail in named case studies, and no commercial terms at all.
- Price transparency1/5
No price, rate or minimum appears anywhere on the site.
- Ownership on exit3/5
Case studies describe client teams trained to own and run what was built, but no general term is published.
- Definition of a result2/5
It sells builds, and no page states what a build includes or how its success is judged.
- Evidence you can check4/5
Ten case studies name the client and a quoted person, though the AdRoll page still shows unfilled placeholders.
- Build depth5/5
Several case studies document the architecture, down to shared Clay functions, scoring models and suppression rules.
- Commitment flexibility1/5
Nothing is published about minimum terms, notice or engagement length.
An editorial read of what the company publishes, not an aggregate of user reviews, and deliberately kept out of this page's structured data.
Who The Kiln is for
B2B revenue teams that already use Clay, or plan to, and need someone to build the scoring, enrichment, routing and signal plumbing behind their outbound and inbound. The published clients are mostly software and technology companies with in-house sales teams, such as Hologram, AdRoll, TwelveLabs and Azuga.
Several case studies end with the client's team trained to operate what was built, which matters to a buyer who wants to run the system afterwards. A buyer shopping on price gets less, because nothing about cost is published before the call.
Strengths and limits
What it does well
- Ten case studies name the client and quote a named person, with figures such as T-ROC's $40M+ pipeline and Crescendo's quarterly pipeline rising from $21M to $35M.
- Several case studies show the architecture, such as AdRoll's five shared Clay functions and Crescendo's 1-to-100 scoring run across 50,000+ companies, so the build can be judged as well as the result.
- Case studies describe training client teams and leaving documentation so they can run the systems themselves, as with Daxko and Sendoso.
- Covers inbound and RevOps on the same data as outbound: the TwelveLabs case study describes a dozen inbound sources consolidated into one scoring and routing engine.
- The homepage says its GTM engineers work with only a few clients at a time.
Where it falls short
- No price, rate, minimum or term is published anywhere on the site; scope and cost are set on a call.
- The 2X acquisition announcement describes 2X's enterprise delivery but says nothing about pricing, staffing or what changes for existing Kiln clients.
- The AdRoll case study still carries unfilled placeholders, '[X rows]', '[Y companies]' and '[Z contacts]', where its figures should be.
- Ownership of what it builds is described in case studies, not stated as a term of engagement.
- Links on its tool stack page carry referral codes, such as ?via= on the Clay, Instantly and Smartlead links, and the page does not mention them.
The Kiln pricing
The Kiln publishes no pricing. There is no pricing page, no rate card and no minimum, and the contact page is a calendar embed for a 30-minute call. The monthly dollar figures on its tool stack page are the software vendors' own prices, not The Kiln's.
The case studies hint at the shape of an engagement rather than its cost. Daxko's ran for more than eight months, TwelveLabs replaced a group of contractors with it, and Clientell was an existing client when a three-day campaign was added. Whether that work is billed as projects, retainers or hours is not stated, and the 2X announcement does not address pricing either.
How an engagement runs
- 1Book a 30-minute call through the contact page; no price or scope is published beforehand
- 2Audit the existing stack, advise on tools and implement them, with Clay as the central orchestration tool, as described for Hologram
- 3Build the data layer: TAM mapping, 1-to-100 account scoring, contact scoring and enrichment waterfalls, as described for Crescendo and Loxo
- 4Set up deliverability and clean the CRM, including Salesforce checks so existing customers are not prospected, as described for T-ROC and Daxko
- 5Launch and scale campaigns across email, LinkedIn and signal plays, testing a channel before adding volume, as described for T-ROC and Clientell
- 6Train the client's team and document the system so it can be run internally, as described for Daxko and Sendoso
What it claims, in its own words

The unit of a result
Sells the build itself
This records what The Kiln publishes about itself, read in September 2026. It is not an assessment of what the company does in practice.
Limits and exclusions
- The homepage says its GTM engineers work on only a few clients at a time
- The work is built around Clay, and nearly every case study is a Clay implementation
- No published price, minimum, term or client fit criteria; everything is set on a call
- Owned by 2X since January 2026, whose announcement describes the combined offer as aimed at enterprise clients
What people say on Reddit
Reddit mentions of The Kiln are about the people rather than the service: co-founder Patrick Spychalski named among Clay voices, an AMA with its head of GTM engineering that was organised by Clay's partner programme, and one passing remark on its process. No comment found describes being a client, and many hits for the name are about pottery kilns.
“Agencies like the Kiln make the copy first and then proceed with the table.”

Verdict
Clay users, or teams about to become one, who need the scoring, enrichment, signal and routing layers designed and their people trained to run them are The Kiln's clearest fit. The named case studies with architecture detail give you specific builds to ask about on the call, and they show both handover and hands-on campaign work.
Nothing here suits a buyer who needs a price before a call, a pay-per-meeting arrangement, or a small fixed-scope project with published terms. Also weigh the 2X ownership: the announcement points towards enterprise delivery, so a smaller team should ask directly who would do the work and what it costs.
The Kiln FAQ
What happened when 2X acquired The Kiln?
2X announced the acquisition on 6 January 2026. The release says The Kiln's GTM engineering joins 2X's delivery team of nearly 1,300 people across the US, Malaysia and the Philippines, aimed at enterprise clients, and that co-founders Patrick Spychalski and Mathias Powell lead The Kiln. It says nothing about pricing, terms or changes for existing Kiln clients.How much does The Kiln charge?
It does not publish a price, a rate or a minimum. The contact page books a 30-minute call. The monthly prices shown on its tool stack page belong to the software it recommends, not to The Kiln's own services.Does The Kiln run outbound campaigns or only build them?
Both, going by its case studies. It ran email and LinkedIn outreach for T-ROC and a three-day Dreamforce campaign in Smartlead for Clientell, while the Daxko and Sendoso case studies describe building systems and training the client's team to run them.Will we own what The Kiln builds?
The site has no general statement on ownership. Its case studies describe work inside clients' own Clay and Salesforce instances, and the Daxko study says The Kiln trained the team to own and operate the systems long-term. Confirm workspace and account ownership in the contract.Does The Kiln only work with Clay?
Clay sits at the centre of nearly every case study, and the homepage says the team includes early Clay employees. The builds also connect Salesforce, HubSpot, Smartlead, Instantly, SalesLoft, HeyReach and Gong, and its tool stack page says the team uses n8n for nearly all of its own automation.What results does The Kiln publish?
Named results in its own case studies, which are unverified: Crescendo's quarterly pipeline rising from $21M to $35M, T-ROC's $40M+ pipeline, Azuga's 640+ hours of manual work saved per week and Hologram's 30-40% of pipeline from the systems built. The AdRoll case study still contains unfilled placeholders where some figures should be.
Others worth a look
This is an independent review. The Kiln is not a client or a partner, we have no affiliate relationship with them, we earn nothing if you hire them, and nobody pays for placement in the directory. Prices were read from the company's own pages in September 2026 and change without notice.
