About

Operators, not consultants

GrowthStack Advisory is a boutique B2B GTM studio founded in 2025 by two operators who built and scaled outbound at Apollo.io, Locus, GoComet, the Landmark Group, and the IKEA Group. We help growth-stage B2B SaaS companies turn pipeline math into pipeline.

What we do

We build outbound SDR engines that generate qualified B2B pipeline in 90 days, and we sit one layer up as fractional GTM leadership when the motion needs to scale. Two services, one philosophy: ship work that compounds, hand over a playbook your team can run after we leave, never bill for activity that doesn't move pipeline.

• B2B lead generation consulting — managed outbound SDR engine, 90-day build, $8k–$25k/month.
• GTM consulting — segmentation, pricing, sales motion, and revenue operations for scale to $10M ARR.

The founders

Shobhit Gupta — Founder & GTM Strategy Lead

Shobhit has spent the last decade building outbound and GTM functions inside companies that scaled fast — Locus (Series C+), GoComet (Series B+), the Landmark Group, and the IKEA Group. He's personally built SDR teams from zero to 23 reps across APAC, EMEA, and North America, generated over $20M in qualified pipeline across logistics-tech, SaaS, and retail-tech, and rebuilt GTM motions for founders moving from founder-led sales to repeatable engine.

He still personally writes the first sequence on every engagement. Connect on LinkedIn →

Ruchi Mittal — Founder & Lead Generation Lead

Ruchi led sales development operations at Apollo.io, where she ran cold email programs against tens of thousands of B2B accounts and helped shape the SDR playbook that Apollo now teaches to its own customer base. She brings deep expertise in cold email deliverability, sequence design, AI-augmented personalization, and the tooling stack that makes modern outbound work at volume without burning domains.

On engagements she owns the engine room — infra, sequences, inbox health, reporting. Connect on LinkedIn →

Track record

• $20M+ qualified pipeline created across B2B SaaS, logistics-tech, and retail-tech.
• Scaled an APAC SDR team from 10 to 23 reps while improving SQLs per rep from 2 to 6/month. Read the playbook.
• Lifted MQL-to-SQL conversion from 10% to 25% for a logistics-tech client. Read the playbook.
• Rebuilt SaaS pricing for a Series B client; average ACV up 38% in 4 months.
• US market entry for an EU SaaS company; first $1M ARR pipeline in 5 months.

How we work

• Flat monthly retainer. Tied to outcomes — pipeline, SQLs, meeting-to-opportunity conversion. Never hourly.
• Small by design. Two operators on every engagement, not a pyramid of juniors learning on your account.
• You own everything. Infra, sequence library, reporting, playbook. When the engagement ends, you keep it and run it.
• Honest no's. If we don't think we can move the needle, we'll tell you in the first call and refer you to someone who can.
