The short answer: a GTM engineering agency builds the machinery behind pipeline: the signals that pick which accounts to work, the enrichment and scoring that rank them, the CRM fields and routing that move them, and the sending setup that reaches the person. Some firms hand that system over; others build it and then run it with you. Of the ten below, five print a price on their own site, two list one only on Clay's partner directory, and three quote every engagement.
Valley is an AI outbound platform that finds the people most likely to buy from you - from live buying signals, natural-language search, or your own lists - qualifies them against your ICP, researches each one, and sends personalized messages across email and LinkedIn that get 15-45% reply rates, against a category average of about 2%.
Key takeaways
Systems built in your own CRM at a published price: The GTM Engineering Company, $5,000 or $7,000 a month, seed to Series B B2B SaaS, a written runbook with every system.
The system and the selling, for technical seed to Series A founders: QC Growth, an embedded GTM team at $12,000 to $20,000 a month on its service pages.
Lowest published entry: GTM Walnut, from $2,500 a month, with most engagements between $2,500 and $6,000.
Fastest dated launch: ColdIQ, a first play in market by day 14 and three by day 45, all in accounts you own.
Series B and later, with inbound to route: The Kiln, now part of 2X, listed on Clay's directory from $10k a month with a three-month minimum.
Before any call: decide whether you are buying a system or a team. That one question sorts this list in half.
How this comparison was checked
Each firm's own website was read on October 19, 2026, and only what is printed there is recorded: services, stated stage focus, any published price or minimum term, named clients, and the results each firm states about itself. Where a price appears only on Clay's partner directory, the entry says so. None of these services was bought for this comparison, so every figure is the firm's own, and each sentence says whose it is.
The first draft of this comparison came from The GTM Engineering Company team. It was rewritten and every claim was checked against each firm's own site, with anything that did not match corrected or removed. QC Growth, at number 2, is also a published client of The GTM Engineering Company. Valley makes outbound software, not agency services, and is not ranked here.
What a GTM engineering agency actually does
It builds the parts of go-to-market that sit between your tools: a signal layer that spots accounts worth contacting (see buying signals, ranked by how close the buyer is), enrichment and scoring that decide the order, CRM fields and routing rules that move an account to the right person, and the email and LinkedIn sending that reaches them. Most firms here build on a similar stack: a signal source (compared in the best B2B intent data tools), Clay or a comparable enrichment layer (Clay's pricing and credits, explained), HubSpot, Salesforce or Attio as the system of record, and separate email and LinkedIn senders.
Two models share the label. A GTM engineering firm builds the system and hands it over, usually inside your own accounts. A full GTM agency, sometimes called a fractional GTM team, builds the same machinery and then works the accounts with you. The second costs more and needs less of your own staff afterwards.
Who needs one
Founders still running every deal: pipeline moves when they are on calls and stops when they go back to the product.
Heads of growth who inherited a stack nobody owns: a CRM, two senders and a Clay workspace with nothing connected. The gap is plumbing, and plumbing has an end point.
Lean sales teams scaling LinkedIn and email: signals have to reach the right rep the same day, and sending has to run across accounts without tripping limits.
Technical founders at devtools and AI companies: they need a partner who knows who evaluates, who blocks on security, and which product signals mean budget is coming.
If none of these describes your week, a GTM engineering agency is probably the wrong purchase this quarter. If the gap is meetings rather than systems, compare B2B lead generation agencies instead; if it is an AI product, see AI development companies for startups.

Give your sales team
an unfair advantage.
The ten are ordered by how well they fit a seed to Series A team that needs a system and someone to work it. Each entry follows the same pattern: what the firm states, what it charges, what to watch for, and when to choose it.
Firm | Best for | Stated focus | Published pricing |
|---|---|---|---|
1. The GTM Engineering Company | Systems built inside your CRM, then handed over | Seed to Series B B2B SaaS | $5,000 or $7,000/mo; enterprise custom |
2. QC Growth | Technical founders who need the system and the selling | Seed to Series A, past product-market fit | $12,000 to $15,000/mo (systems and ops); $15,000 to $20,000/mo (full service) |
3. GTM Walnut | A fast build and run at a low monthly fee | Seed to Series C B2B SaaS and services | From $2,500/mo; most $2,500 to $6,000 |
4. ColdIQ | Proven ICPs that need plays live quickly | Generalist B2B | Scoped per client; 90-day initial term |
5. The Kiln (a 2X company) | Series B and later with inbound to route | Post Series B to enterprise (Clay directory) | Not on its site; Clay directory lists $10k+/mo, 3-month minimum |
6. RevDash | Enterprise outbound run by dedicated BDRs | Infrastructure, security, devtools, open source | Flat monthly fee per dedicated employee; rate not published |
7. Automate RevOps | Large CRMs with no readiness scoring | B2B marketing teams | Free Demand Map; custom quotes (Clay directory lists $5k+/mo) |
8. Arise GTM | HubSpot-based SaaS and fintech | B2B SaaS and fintech | Assessment £10,000; £25,000 per GTM motion |
9. CIENCE | Managed SDR teams at a visible price | 250+ industries | $2,000/mo team + $499/mo platform + SDRs from $1,750/mo each |
10. memoryBlue | Proven motions entering a new market | B2B technology and professional services | Not published (outcome-based or retainer) |
1. The GTM Engineering Company: systems in your own CRM, at a published price
The GTM Engineering Company builds RevOps, enrichment and outbound systems inside the client's own CRM, for B2B SaaS teams from seed to Series B. Founder Jorge B. Macías was BrainHi's second sales hire, moving from SDR to Account Executive to Revenue Operations, then sold at Reprise and Offsite. Every system ships with a written runbook, and every tool is bought and owned by the client, never resold.
Its case studies carry numbers: a 2,062-company ABM audience live on LinkedIn ads for Fluint, 11 meetings in a week for trumpet, and 48,703 of 65,107 open leads enriched with three live scores for Slate. Named logos include webAI, Opsera, NodeSource and SimpleClosure. It says a typical engagement runs three to six months at five to ten hours a week, with quick wins in the first two to four weeks.
Pricing: Starter $5,000 a month, Growth $7,000 a month (its recommended tier), Enterprise custom (published on its site).
Watch for: it is founder-led, with only the founder named. Its case-study results are meetings, records and hours saved rather than revenue. HubSpot and Salesforce are the only CRMs it names.
Choose it when you have a CRM, someone who will own the system afterwards, and you want the price before the first call.
2. QC Growth: an embedded team for technical founders
QC Growth is an embedded GTM team for seed to Series A B2B software founders past product-market fit, working across developer tools, healthcare, deep tech and AI. A pod of a GTM lead, a GTM engineer and outbound and ops support runs inside the client's CRM, covering strategy, outbound infrastructure, messaging, campaigns and reporting.
The team has sold what its clients sell: Luke Bivens held key roles at Gatsby (acquired by Netlify), Shane O'Connor was the founding commercial hire at Scalar, and Kori Bivens, a former VP at RVO Health, leads healthcare GTM. Portfolio work includes Netlify, Gatsby, Turso, Mastra AI, ZeroEntropy, Grafbase, Arcjet and Eraser.io, and Grafbase and Eraser.io's founders credit it with their first enterprise customers. Signals include GitHub activity, funding and web visits; enrichment runs on Clay, records live in Attio, HubSpot or Airtable, and sending runs on HeyReach and Email Bison. On October 1, 2026 it acquired The DevTool GTM Company.
Pricing: GTM Systems and Ops at $12,000 to $15,000 a month, Full Service GTM at $15,000 to $20,000 a month, starting with a three-month sprint; most engagements run 8 to 18 months, with no equity on the services. Its own comparison puts a senior in-house GTM team at $57,000 to $81,000 a month plus 1.25% to 2.75% equity. (One of its blog posts quotes $7,500 to $25,000; this page uses the service pages.)
Watch for: it is built for seed to Series A, so a company with a senior in-house team gets less from it. It is not an appointment-setting shop measured in meetings a month.
Choose it when your product has traction, the motion still runs through the founder, and you want one team to build the system and work the accounts.
3. GTM Walnut: a fast build and run, from $2,500 a month
GTM Walnut builds AI-native GTM systems for seed to Series C B2B SaaS and services companies and states 40+ clients. Founders Prashant Mantri (revenue operations at two unicorns and a Series B startup) and Soumya Surabhi (head of demand generation at Y Combinator and Sequoia-backed startups) work directly with each client. The stack covers website visitor identification, LinkedIn buying signals, waterfall enrichment through Clay, orchestration in n8n, Claude Code and Clay, Instantly for email and LinkedIn multi-sender campaigns, with a person approving each send in Slack.
It states a 30-day average to a live system, two weeks from contract to first send, and $320M+ in pipeline across its clients. Its default is build and run: it writes the messaging and runs the campaigns, not only the plumbing.
Pricing: a fixed monthly retainer from $2,500 a month; most engagements land between $2,500 and $6,000.
Watch for: the pipeline total is self-reported with no published method. The focus is broad B2B rather than one vertical.
Choose it when you want a working system quickly and a lower monthly fee than a full embedded team.
4. ColdIQ: dated launch milestones, in accounts you own
ColdIQ builds and runs email and LinkedIn outbound and states 300+ companies helped. Launch is a dated milestone: a controlled play in market by day 14 and three plays running by day 45. Everything runs in accounts the client owns, on dedicated secondary domains and mailboxes with SPF, DKIM and DMARC set up, and the prompts and playbooks stay with the client.
Its AirOps case study reports $7.83M in qualified pipeline, $1.52M closed-won and 164 deals in 10 months. ColdIQ has also moved into software: its homepage now sells a GTM data API for Claude Code and AI agents.
Pricing: the managed service is scoped per client, with ColdIQ's fee kept separate from third-party software, on an initial 90-day term. The data API is a separate purchase, from a free tier to $4,999 a month.
Watch for: it is outbound-centric, with little positioning or category work. Messaging to technical buyers needs testing.
Choose it when your ICP is proven and the bottleneck is getting plays live.
5. The Kiln: Clay-native systems for Series B and later
The Kiln builds inbound, outbound and RevOps systems with a team that includes early Clay employees, and it was acquired by 2X in January 2026. Named clients include Windsurf, Browserbase, Loxo, Sendoso and T-ROC; its T-ROC case study reports more than $40m in pipeline, and its Crescendo case reports $14M in four months.
Pricing: not on its own site. Its Clay partner directory profile lists $10k+ a month with a three-month minimum, so a first engagement starts at $30,000 or more, and names its best fit as post Series B to enterprise B2B teams.
Watch for: the stated stage is a mismatch for seed and Series A. Clay sits at the centre of its work, although its toolstack page recommends many other tools.
Choose it when you are past Series B with inbound volume worth routing and scoring properly.
6. RevDash: dedicated BDR teams for enterprise outbound
RevDash, based in White Plains, New York, builds and executes outbound GTM strategies and staffs dedicated BDR and SDR teams across email, calling and LinkedIn. It works with enterprise software, AI, infrastructure, security, developer tools and open-source companies, including US and EMEA expansion. Founder Gent Dedushi started it in 2019 after 15 years of enterprise sales at companies including Google, IBM, VMware, Elastic and CoreOS.
Published logos include SUSE, Isovalent, Authzed, Daytona, Flux, AKKA and Broadleaf Commerce. It says a team can be fully ramped in four to six weeks.
Pricing: a flat monthly subscription per dedicated employee, covering strategy, management and reporting; the rate is not published. It claims 40-50% savings compared to competitors and in-house BDR teams, without a source.
Watch for: the site publishes no quantified client results. Ask for two references at your stage.
Choose it when you sell infrastructure, security or developer tools into enterprise and want people running the outreach.
7. Automate RevOps: readiness scoring for marketing-owned pipeline
Automate RevOps, founded in 2025 in Brooklyn by David Moreira and Marcos Stubrin, scores every account in a market on awareness and readiness for B2B marketing teams. Work starts with a free Demand Map delivered in 48 hours, moves to a custom-quoted diagnostic of five to ten days, then a 90-day build. If the diagnostic cannot identify three meaningful leaks, the client does not pay, and the fee is credited toward the build. Fees are flat, never a percentage of spend. It is a Clay partner and publishes its method as a book, The Demand Compass.
Its case studies are anonymized but detailed. One AI trust and safety platform went from about 27,800 accounts to 4,176 scored, 747 in market and 51 routed over four months, at a 0.8% bounce rate, with 14 positive replies; the study notes none of it was booked pipeline yet. It also publishes the cohorts that produced nothing.
Pricing: custom quotes on its own site; its Clay directory profile lists $5k+ a month with a one-month minimum.
Watch for: no named clients, so none of the numbers can be checked with a reference call.
Choose it when your CRM is full, your scoring is empty and marketing owns the pipeline number.
8. Arise GTM: HubSpot-native RevOps for SaaS and fintech
Arise GTM is a London AI GTM and RevOps consultancy for B2B SaaS and fintech. Founder Paul Sullivan wrote Go-To-Market Uncovered (Wiley, 2025), and the firm states 9+ years as a HubSpot partner. It pairs product marketing with RevOps, business intelligence and AI, and deploys a pre-built revenue operating system customised to the client in 30 days or less.
In its HubX case study, a fintech platform used by major banks, outbound rep productivity rose 20% and admin time fell 40% after a RevOps rebuild.
Pricing: a full assessment at £10,000, deducted if you proceed, then £25,000 per GTM motion before a scoped retainer.
Watch for: the delivery it shows is HubSpot; its Salesforce work is migration to HubSpot. Outbound execution is not the centre of the offer.
Choose it when you run on HubSpot and the problem is misaligned data and reporting, not message or volume.
9. CIENCE: managed SDR teams with a visible price
CIENCE runs appointment setting and lead generation with managed SDR teams, cold email and calling, and builds a revenue system before running it. Its assets were acquired by graph8, and execution runs on the graph8 platform. It states clients across 250+ industries and lists meetings booked for Okta, Microsoft, Google, Uber, Salesforce, Segment and Airbnb, with 115+ case studies.
Pricing: a campaign team at $2,000 a month and the graph8 platform at $499 a month, plus SDRs from $1,750 (offshore), $2,500 (Europe) or $3,500 (US) per SDR per month, a performance bonus and a one-time setup fee. Month to month. A 60-day revenue system build is quoted separately.
Watch for: a system built on a vendor's own platform does not transfer cleanly. Ask what you keep before signing.
Choose it when you want outbound handled at a price you can model before the first call.
10. memoryBlue: enterprise sales development at scale
memoryBlue has run outsourced sales development since 2003 and states 650+ dedicated SDRs, ADRs and AEs across seven offices, including London and Singapore, in 30+ native languages. Clients include UiPath, Wiz, Palo Alto Networks, Splunk, Adobe, Couchbase and CrowdStrike, and a Gainsight case study reports 170% quota attainment. Its audition-to-hire model lets proven reps move onto the client's own team, and it says 85% of the meetings it books come from the phone.
Pricing: no single published rate; it works on outcome-based or retainer models. It puts a fully loaded in-house SDR at roughly $140,000 a year.
Watch for: it expects 70-80% confidence in the ICP and is not built for finding product-market fit from zero.
Choose it when you have a working motion and need more of it, especially in a new market or language.
Whichever firm builds the system, the message is what the prospect sees.
Give your sales team
an unfair advantage.
Decide whether you are buying a system or a team. If nobody on your team will own the system in 60 days, a build on its own becomes a well-documented thing nobody runs.
Check the stage the firm says it serves. The Kiln's directory profile says post Series B; QC Growth says seed to Series A. Read the firm's own stated fit before the call.
Ask what stays in your accounts. A system built in your CRM and sending accounts is yours; one built on a vendor's platform leaves with the vendor. Get it in the agreement.
Ask about the signal layer, not the tool list. Every firm here names Clay. Ask which signals trigger outreach for a company like yours, and what happens when an account fits the filters but has no trigger.
Match the commitment to your runway. Terms here run from month to month (CIENCE) through a 90-day initial term (ColdIQ) and a three-month sprint (QC Growth) to a three-month minimum at $10k+ a month (The Kiln, per Clay's directory).
Ask for two clients at your stage. Named companies, your category, and what the first two quarters produced.
Agency or software: where Valley fits
Agency or software? An agency rents you people and a process; software rents you the process and leaves the people to you. Agencies win when nobody on your team can run outbound or when phone is the channel. Software wins when one person can own it, when your buyers are on LinkedIn and email, and when you want the list, the research and the messages to stay in your own accounts.
Where Valley fits (Valley's own product). Valley is software for the signal-to-message part that several of these firms build by hand: it finds people showing buying signals or matching a natural-language search, qualifies them against your ICP, researches each one and drafts a personalized message in your voice. You approve every message, or let them flow. Starter is $199 a seat a month, or $149 billed quarterly, for LinkedIn; Plus, at $299 ($249 quarterly) through a demo, adds 1,000 emails a month. There is a 7-day trial. The longer comparison is lead gen agency vs outbound software, and agencies running this for clients can read LinkedIn outbound for GTM agencies.
FAQ
What is a GTM engineering agency? A firm that builds the systems behind pipeline: signals that pick accounts, enrichment and scoring that rank them, CRM fields and routing that move them, and the email and LinkedIn sending that reaches the person. Some hand the system over; others also run it.
What is the difference between a GTM agency and GTM engineering? Who works the accounts after the system goes live. A GTM engineering firm builds and hands over, often with documentation; a full GTM agency, or fractional GTM team, builds and then runs the motion with you.
How much does a GTM engineering agency cost? On the firms' own sites: GTM Walnut from $2,500 a month (most $2,500 to $6,000), The GTM Engineering Company $5,000 or $7,000 a month, QC Growth $12,000 to $20,000 a month for an embedded team, and CIENCE $2,000 a month plus $499 for its platform plus SDRs from $1,750 each. Arise GTM charges £10,000 for an assessment and £25,000 per GTM motion. Three of the ten publish no price for the service.
Is a GTM engineering agency worth it for a seed-stage startup? When the founder is the only person who can run a deal and the tools are bought but not connected, often yes. The risk is buying a build nobody will own, so pick an engagement that leaves a runbook or one that includes people to run it.
Which GTM agencies work with developer tools and technical buyers? QC Growth (Netlify, Gatsby, Turso, Mastra AI, Grafbase, Arcjet, Eraser.io), RevDash (SUSE, Isovalent, Authzed, Daytona, Flux) and The Kiln (Windsurf, Browserbase), although The Kiln's stated fit is Series B and later.
Can a GTM engineering agency run LinkedIn outbound? Yes. QC Growth and GTM Walnut both build LinkedIn sending into the systems they install, ColdIQ runs LinkedIn and email plays, and RevDash staffs reps who do the outreach. If you want your own team sending, confirm the agency hands over the sequences and the sending accounts.
Agency or software: which should a team choose? Hire an agency when nobody on your team can own outbound for the next quarter. Use software when one person can, and you want the list, the research and the messages to stay with you.
