Scaling Your Tech Stack

The tools that got you to Series A may not get you to Series C. Scaleups face unique challenges: rapidly growing teams, increasingly complex processes, and the need for enterprise-grade reliability.

The Scaleup Stack Challenge

At the scaleup stage, you need tools that:

  • Handle 10-100x data volume without performance issues
  • Support team structures with proper permissions and workflows
  • Integrate deeply with your other systems
  • Provide enterprise security and compliance features
  • Offer dedicated support and SLAs

When to Upgrade

Signs you have outgrown your startup tools:

  • Performance degradation as data grows
  • Missing features your team needs daily
  • Integration limitations blocking automation
  • Compliance requirements you cannot meet
  • Support response times impacting operations

Building for Scale

The best scaleup stacks share common traits:

  • CRM Foundation: Salesforce or HubSpot as the system of record
  • Data Infrastructure: Segment or similar CDP for unified data
  • Specialized Tools: Best-of-breed for critical functions
  • Integration Layer: APIs and automation connecting everything
