MarkeStac

MarkeStac is a CRM consulting and marketing automation agency based in India with 7+ years in the business. The company has delivered over 350 projects and employs 30+ certified experts. They position themselves as implementers of HubSpot, Salesforce, and Active Campaign systems—not just tool deployments but what they call "revenue operating systems" designed around how a business actually runs. The team holds certifications as a HubSpot Platinum Partner, Salesforce Certified Partner, and Active Campaign Certified Partner.

Services and capabilities

MarkeStac's core offering spans four areas: CRM implementation, migration, optimization, and plan upgrades. Within CRM Launch, they define revenue goals, map core processes, design system structure, recommend automation, and guide team adoption. For clients moving systems (CRM Migration), they assess what transfers, clean and validate data, redesign broken processes, and plan risk-free cutover with realigned automations. CRM Optimization audits the full ecosystem, establishes a single source of truth, clarifies customer journeys, and aligns teams and workflows. Plan Upgrades identify limitations in current tiers, unlock revenue-critical features, expand automation and reporting, and enable scaling without disruption.

They also offer end-to-end automation across marketing, sales, customer support, and business operations. Marketing Automation covers automated lead capture and scoring, email and WhatsApp drip campaigns, personalized customer journeys, and campaign performance tracking. Sales Automation includes automated follow-ups and reminders, deal and pipeline tracking, sales performance dashboards, task and activity automation, and AI-driven deal insights. Customer Support Automation deploys auto ticket creation and routing, chatbots for instant responses, SLA tracking and escalation rules, automated follow-ups, and self-service knowledge bases. Business Operations Automation handles automated approvals and notifications, task workflows triggered by actions, real-time dashboards and reporting, error reduction, and standardized SOP implementation.

Data management is a distinct service line: deduplication, cleansing, reconciliation, importing, standardizing, bulk updating, and aggregation for comprehensive insights. They also offer white-label CRM services with dedicated resource provisioning and provide custom HubSpot development. Digital marketing services round out the portfolio.

Notable work

MarkeStac publishes detailed case studies with measurable outcomes. Xsellerate, a B2B revenue consulting firm in Dublin, had a functional but broken HubSpot setup with inconsistent deal stages, slow lead response, and unreliable reporting. MarkeStac reduced their speed-to-lead from 60 minutes to under 5 minutes through CRM optimization and workflow automation.

For IMAST, an India-based SaaS and loyalty platform, MarkeStac built a full HubSpot revenue operating system from scratch, migrating data and deploying end-to-end pipeline automation. Results: portal usage score of 71, sales activity up 84%, marketing up 10% within months of launch.

Dr. Kelly's Surgical Unit, a seven-location veterinary chain in the US, was unknowingly sending emails from a blacklisted IP and landing in spam. MarkeStac migrated them to a dedicated IP, executed a warm-up sequence, rebuilt the contact database, and deployed location-specific automation across all clinics, resulting in consistent inbox delivery and fully automated patient communication.

The Bosco, a New York experiential technology company, was paying for Salesforce with poor adoption and messy data. MarkeStac migrated 50,000+ records to HubSpot, built workflows, pipelines, and sequences, connected four key integrations, and created custom reporting. Within 4 weeks: marketing up 39%, sales activity up 5%.

Billetto, an event management platform in Denmark, consolidated 15+ disconnected tools into HubSpot Enterprise, integrated 15 platforms, and engineered end-to-end sales and marketing automation. Result: saved €78,000–€102,000 annually and achieved predictable revenue forecasting.
