Part 2: Product Tech Stack – Building for Scale and Agility
As product complexity grows, so does the risk of slowing down. For growth-stage companies, the challenge isn’t just building software, it’s building infrastructure that keeps pace with the business.
At Fulcrum, we help our portfolio companies evolve from scrappy MVPs to enterprise-grade platforms. The right product stack won’t just support your roadmap: it will shape what’s possible.
Core Infrastructure: Build on a Strong Foundation
For most teams, AWS is the starting point—offering flexible compute, storage, and scaling. Others opt for Azure or Heroku to accelerate early deployment.
Databases like Postgres, MongoDB, and Redis power high-volume applications, while Kubernetes and AWS Fargate give teams control over containerized workloads and microservices.
Takeaway: Choose infrastructure that can evolve with your architecture. Avoid early ceilings that lead to expensive rewrites.
Front-End & Back-End: Ship Faster, Smarter
Modern product teams favor speed and flexibility. We see stacks anchored in React, Vue, and Angular on the front-end, paired with Python, Node, Ruby on Rails, or Elixir on the back.
Github, Shortcut, and LaunchDarkly help streamline dev cycles, automate deployment, and mitigate risk.
Takeaway: Invest in frameworks your team can move fast in—and scale with confidence.
Product Ops: Aligning Teams Around Outcomes
Roadmap alignment is critical at scale. Tools like Productboard, Jira, and Linear keep engineering, design, and GTM teams synced.
Figma drives collaboration from wireframe to prototype. Tools like Tableau, Heap, and Hex surface product usage trends that sharpen prioritization.
Takeaway: Visibility fuels velocity. The right ops stack makes product feedback actionable across the org.
The AI Layer: A New Kind of Velocity
AI is changing the way product teams operate. It’s not just automating tasks—it’s accelerating creativity, iteration, and decision-making.
- ChatGPT and Claude are helping teams generate documentation, write code snippets, and brainstorm feature ideas.
- Tools like Cursor and Toolflow are augmenting code review and backlog grooming.
- LaunchDarkly + Intercom are powering adaptive feature rollouts based on real-time user input.
- Softr is the easiest way to turn your data into modern business apps — no coding or design skills required.
Takeaway: AI-native workflows are becoming a competitive edge. Teams that embrace them now will out-iterate the rest.
What Resilience Looks Like in a Product Stack
A resilient product stack is:
- Cloud-native – Scales with demand
- Modular – Easy to adapt or extend
- Cross-functional – Supports transparency across teams
- Secure & Compliant – Especially in regulated markets
- AI-Enhanced – Leverages automation where it can accelerate outcomes
Looking Ahead
As companies scale, product velocity becomes a strategic asset. At Fulcrum, we work with founders and engineering leaders to design stacks that don’t just support growth; they unlock it.
