GTM Engineering for Early-Stage Software Companies

BEFORE YOU HIRE your next SDR

Your sales development reps (SDRs) open the CRM to qualified accounts, the right decision-maker, and a first draft ready to send. We build the system that does the research and list work, so they spend their day selling. Tested, documented, and yours to keep.

20 minutes. Three fixes you can use, whether or not you hire us.

GTM IS A
system

Most pipelines are a stack of tools nobody fully owns. We build go-to-market (GTM), the path from stranger to customer, the way good engineering teams build product: one source of truth, clear contracts between tools, evals before scale, and every decision written down.

01
DEFINE
Ideal customer profile (ICP), buyer personas, motions, and guardrails. Who we sell to, how they arrive, and what we will never do.
02
SOURCE & ENRICH
Accounts land in your database first, then flow through enrichment and back through a validated check.
03
RESEARCH & SCORE
AI agents find the right decision-maker with cited evidence. Transparent scoring explains every point.
04
SYNC & ROUTE
Qualified records sync to your CRM without duplicates and without overwriting edits your team made by hand.
05
ENGAGE
Personalized drafts, reviewed by a human, sent from protected domains with suppression honored.
06
MEASURE & LEARN
Funnel reporting straight from your database, plus notes from every sales, success, and product call turned into CRM data, so the system learns from what customers say.
Your data, your database
Your database is the source of truth. Enrichment tools, the CRM, and sequencers are views onto it, not the place it lives.
Evals before scale
Agents are graded against hand-labeled accounts before they touch the full list.
Humans approve the send
Nothing reaches a prospect without review. Accurate claims, compliant footers, unsubscribes honored.
Decisions written down
Architecture decision records, tests, and a setup guide your team can actually follow.

What We Build

GTM
services

Every engagement is scoped around the motion you actually run. Start with one piece, like enrichment or CRM hygiene, or have the full pipeline built end to end.

01
01
GTM DATA & ENRICHMENT
Define your ideal customer profile (ICP), then build the full list of accounts that fit it, your total addressable market (TAM), from sources whose terms allow it, and run it through enrichment waterfalls that check several data providers. Records live in your database with an append-only history, so you always know where a field came from.

02
AI RESEARCH AGENTS
AI agents that research each account, find the real decision-maker, and cite the page they found it on. Graded against labeled accounts, with spend logged per run so cost never surprises you.
Account Research Decision-Maker Discovery Evals Cost Controls

03
CRM & REVOPS
Revenue operations (RevOps) is the plumbing behind your sales team: customer relationship management (CRM) architecture, syncs that never duplicate records, lifecycle stages, scoring, and routing. Re-runs write nothing new, manual edits are never overwritten, and the funnel reports itself.
CRM Setup Lead Scoring Routing Funnel Reporting

04
OUTBOUND & LIFECYCLE
Sequencing infrastructure, sending domains, suppression lists, and human-reviewed drafts for outbound. Welcome flows, drips, in-app messages, and text messages for the people already in your product.
Sequencing Deliverability Lifecycle Email In-App Messaging
→
05
PRODUCT-LED GROWTH
Pricing and packaging, billing, plan gates, feature flags, analytics, and error monitoring. The plumbing that turns signups into paying customers and tells you why they did or did not convert.
Pricing & Packaging Billing & Plans Feature Flags Analytics

06
CONVERSATION INTELLIGENCE
Your sales, success, and product calls are already being recorded by your dialer or summarized by AI notetakers. We turn those notes into CRM data: pains, objections, competitors, feature requests, stakeholders, and next steps. Reps follow up faster, product gets a ranked list of what customers ask for, and targeting and messaging learn from what people actually say.

LAUNCH CONTENT & CREATIVE
The pipeline needs something worth clicking. Launch films, paid social creative, founder content, and product demos, shot and cut in house so the message and the system ship together.

THREE WAYS
to work together

No packages. Every engagement starts with a conversation about your motion, your stack, and what is breaking. Then we send a fixed-scope proposal.

TWO MOTIONS
one system

Let one kind of buyer come to you. Go find the other. Run both through one database, so every signal makes the next one smarter.

Automated stepHuman checkpoint
The SDR Math

LET THE SYSTEM RUN OUTBOUND
put your SDRs on inbound

A system can handle research, list building, and first drafts. Your SDRs get those hours back for inbound, the people who already want to talk.

Assumes the system takes over 70% of manual outbound work and a 2,000-hour work year per SDR. This is the value of the time freed, before the cost of the system, which we scope with you. Example numbers, not benchmarks.

SDR time freed for inbound, per year $0 0 hours a year, about 0 SDRs, with no new hires

Phased Rollout
PHASE 1
PROVE ONE MOTION

Launch the self-serve side first. Get real users and real results before you pitch anyone.

PHASE 2
OPEN THE SECOND

Start outbound on a small test list. Pitch with proof, not promises.

PHASE 3
SCALE WHAT WORKS

Expand what is working. Automate only the steps that have proven accurate.

Guardrails
SAFE TO SCALE

Guardrails are what make automation safe to run at volume. They live in the system itself, so they hold even when nobody is watching.

01
No cold outreach to consumers

Outbound targets businesses only. Individuals hear from you after they opt in, never before.

Enforced by: Targeting rules
02
No sensitive records as leads

Court filings, medical data, and similar records stay off-limits, even when they are technically public.

Enforced by: Source allowlist
03
Permitted data only

Every data source is checked against its terms of use before it enters the pipeline.

Enforced by: Source allowlist
04
A person approves every send

The system drafts and a person reviews and sends. Nothing goes out on autopilot.

Enforced by: Review step
05
Accurate claims only

No guaranteed outcomes and no invented stats. Every message is checked for accuracy before it goes out.

Enforced by: Review step
06
Compliance built in

Unsubscribe links, a physical address, and a suppression list checked before every send. Separate sending domains protect your main one.

Enforced by: Sequencer + suppression list
07
Decisions on record

Every tradeoff is written down, so your team knows why the system works the way it does.

Calls follow consent rules

Recording disclosures where state law requires them, calling hours honored, and no automated calls or texts to mobile numbers without consent.

WHAT WE MEASURE
and what it decides

Every build ships with a scoreboard. It ties each part of the system to the revenue lever it moves, so you can see what is working and we know what to change next. We baseline your numbers before we build, so growth is measured against your numbers, not ours.

William Mauro, Founder of Vantage Mode
WILLIAM MAURO
GTM Engineer
"Go-to-market is a system. I build it like software, then stay to make it better every quarter."

William Mauro is a GTM engineer and product builder with more than a decade of experience across software, go-to-market, and digital execution. He has worked everywhere from early-stage startups to Fortune 500 companies, so he knows what a growing team needs and what it can skip.

Before founding Vantage Mode, Will co-founded a commerce platform that let people shop directly from social content, building major retail partnerships along the way. He then led North American customer success at an enterprise content management company, managing accounts across fashion, luxury, electronics, and home goods.

Today he builds the data, AI, and CRM systems that turn a target market into qualified pipeline, and the content that gives that pipeline something worth clicking. He has built products end to end, from pricing and billing to the outbound pipeline that finds the right decision-maker at every account.

FAQ

Everything you need to know before we start working together.

Ask Directly →
What does a GTM engineer actually do?
+
GTM stands for go-to-market: everything that turns a stranger into a customer. A GTM engineer builds the systems your sales and marketing teams run on: where account data comes from, how it gets enriched and researched, how leads are scored and routed, how records sync to your CRM, and how outreach and reporting work. Think of it as software engineering pointed at pipeline instead of product.
Will this replace our SDRs?
+
No. A sales development rep (SDR) finds and qualifies new prospects so your closers have meetings to run. The system takes over the research, list building, and first drafts, so your SDRs spend their time talking with real buyers. Many teams use it to get more from the SDRs they have before hiring the next one.
Do you work in our existing stack?
+
Yes. We work in the tools you already pay for, whatever they are, and only add something new when it clearly earns its place. The process does not depend on any one tool.
Will you send email on our behalf?
+
By default, no. We build the drafting, review, and sending infrastructure, and a person on your team approves what goes out. Sending domains are kept separate from your main domain, suppression lists are honored, and every message stays CAN-SPAM compliant.
How do you keep AI research accurate?
+
Agents have to cite the page where they found each answer, and they are graded against a hand-labeled set of your real accounts before they run on the full list. Anything uncertain goes to a human review step instead of straight into your CRM.
Do you still produce video?
+
Yes, as part of go-to-market. Launch films, ad creative, founder content, and product demos are produced in house, so the creative and the pipeline it runs through are planned together.
How does pricing work?
+
Audits and builds are fixed-scope and fixed-price, whether you start with one piece or the full pipeline. Fractional work and upkeep are monthly retainers. Tools like your data provider and sequencer run on your own accounts, and you pay those vendors directly. After a discovery call, we send a proposal with clear deliverables, a timeline, and a price. No surprises.

✦
GOT IT
Thanks for reaching out. We'll review everything and follow up within 24 hours to schedule a call.
What do you do with our call notes?
+
We usually work from the notes your AI notetaker or dialer already writes, not the raw recordings. The system pulls out the fields your teams care about, like pains, objections, competitors, feature requests, and next steps, and writes them to your CRM. Recording consent stays with your existing process, personal details are redacted before anything syncs, and access follows your CRM permissions.
How do you prove it is working?
+
We baseline your numbers before we build anything, then track the metrics each piece of the system is meant to move: pipeline created, speed to lead, reply and meeting rates, conversion, and cost per qualified account. You get a scoreboard and a regular review, and every change is tested against that baseline, so the numbers decide what we do next.
