B2B lead generation and GTM services, built in this order

The short answer

GrowthStack Advisory is a two-person B2B go-to-market consultancy that builds outbound and sales development engines for growth-stage technology companies, then hands them over. Engagements follow one commercial structure: a $750 GTM Diagnostic delivered in 5 to 7 business days, then a monthly retainer starting at $2,000, with an optional performance component on enterprise motions. The work covers ICP and segmentation, messaging and sales playbooks, email, LinkedIn and calling sequences, sending infrastructure and deliverability, CRM workflows, SDR coaching, and pipeline reporting. A recommended 90 day engagement is one full attribution cycle, and it ends with the playbooks, dashboards and workflows owned by your team rather than the supplier. Shobhit Gupta and Ruchi Mittal both ran the revenue engine at Locus, one leading global sales development and the other running inside sales. Named client work includes Easyship, ConvertCart, WorkStore and NuVista AI, an AWS Advanced Consulting Partner in Atlanta.

Where pipeline usually breaks

In most engagements the problem is one of these three, and they are worth checking in this order.

01

Targeting the right set of accounts

You know your market. The question is which accounts inside it close fastest.

Two founders who have run a sales organisation together

They overlapped for about two and a half years building the revenue engine at Locus, one leading global sales development, the other running inside sales. The people who scope the work are the people who do it. More on how GrowthStack started.

GTM and qualification

Ten years building and running SDR and GTM functions rather than advising on them from outside. He led global sales development at Locus and GoComet, and built the GTM function from scratch at Landmark Group's Logistiq division. He owns targeting, positioning and the qualification standard.

B2B lead generation and GTM consulting FAQs

What does GrowthStack Advisory do? +

We are a boutique B2B GTM and lead generation studio. We build lead generation engines, ICP and messaging frameworks, multi-channel outbound sequences, SDR playbooks and coaching, AI toolstack setups, and GTM reporting for growth-stage startups and sales teams.

Who is GrowthStack Advisory for? +

Growth-stage B2B startups and sales teams that need qualified pipeline. Usually founders running founder-led sales, revenue leaders, heads of sales, and SDR or RevOps leaders whose outbound execution, messaging, qualification or reporting is inconsistent.

Do you only advise, or do you execute? +

We execute. Engagements include writing messaging, reviewing sequences, defining qualification criteria, coaching reps, setting up reporting and changing campaigns based on real pipeline data. The objective is to hand over frameworks, workflows and playbooks the team runs internally.

What does AI-led, human-driven mean in practice? +

AI does account research, personalisation, prioritisation, lead scoring, workflow automation and campaign analysis. Human judgement stays on positioning, qualification, conversations and decisions.

How is this different from hiring an SDR agency? +

Most agencies run activity: they send volume and report meetings booked. We build the system underneath, covering targeting, messaging, qualification, infrastructure and reporting, so results can be traced to a cause and your team can eventually run it without us. The full comparison is in SDR agency vs GTM consultant vs in-house.

What is the minimum commitment? +

Most engagements run in ninety day cycles, enough time to build the foundation and see a full attribution cycle. Shorter diagnostic engagements are available for teams that want a system audit first.

Who this is for, and who it is not

Who this is for

Who this is not for

  • Teams wanting a guaranteed meeting count. That is a real offer elsewhere. It is not this one.
  • Teams wanting outbound run permanently. Engagements end with a handover. If the goal is to outsource the function for good, an agency fits better.

What the $750 GTM diagnostic actually reviews

Most engagements start here. Delivered in 5 to 7 business days. The full scope is on the sales pipeline audit page.

What gets reviewed

What you leave with

  • A written 30, 60 and 90 day plan, prioritised, so you know what to fix first and what can wait.
  • A clear read on whether the problem is targeting, messaging, infrastructure or qualification. These need different fixes and are routinely confused for each other.
  • The fee credited toward setup if you move into a 90 day engagement within 14 days.
See what each engagement includes →

How engagements are structured, and what they cost

Most engagements follow the same shape: setup and implementation, plus a monthly retainer, plus an optional performance component. Which one fits depends on how much is already working.

$750 one-time

GTM Diagnostic

For when you are not yet sure what is broken, or want a second opinion on a motion you already run before committing budget to changing it. Delivered in 5 to 7 business days.

From $2,000 / month

GTM Growth Sprint

For when you have a product and a sales motion, one or two ICPs, and need a structured outbound engine built or repaired around them.

From $3,500 / month

GTM Scale Partner

For when you are running several markets, ICPs or channels, or you have SDRs who need enabling and a sales leader who needs a sparring partner.

Custom

Enterprise and performance

For when deal sizes are large, the motion is enterprise, and you want GrowthStack carrying real ownership of pipeline rather than advising on it.

What moves the number

  • Markets and ICPs. One geography and one ICP, versus multiple markets, segments and personas.
  • Channels. An email-only motion, versus a coordinated email, LinkedIn and calling motion.
  • Infrastructure complexity. Domains, mailboxes, deliverability, data enrichment, CRM, reporting and integrations required.
  • Level of execution. Advisory and playbooks, versus GrowthStack actively supporting prospecting, qualification, pipeline generation, SDR management and team coaching.

What you are committing to

  • A 90 day initial commitment is recommended, after which the engagement moves to a monthly model with 30 days’ written notice.
  • Third-party software, data, domains and email infrastructure are paid by you and stay yours, so the engine does not leave when the engagement does.
  • GrowthStack does not guarantee a fixed number of meetings, opportunities or revenue.
  • The $750 diagnostic fee is credited toward setup if you move into a 90 day engagement within 14 days.
