Stephen Goldberg, CEO of Harper, has been named a 2025 Most Admired CEO by the Denver Business Journal for his leadership and impact on Denver’s tech community.

A leading U.S. auto parts retailer used Harper’s Early Hints technology to overcome Core Web Vitals failures, achieving faster load speeds, dramatically improved indexation, and an estimated $8.6M annual revenue uplift. With minimal code changes, the proof-of-concept validated that even small performance gains can unlock significant growth opportunities for large-scale e-commerce businesses.

A U.S. mid-market online retailer struggling with Core Web Vitals and mobile performance saw search visibility and engagement plateau despite ongoing optimization efforts. By deploying Harper’s Early Hints technology in a 30-day proof of concept, the retailer achieved faster load times, 72% fewer poor mobile URLs, and an estimated $600K annual revenue uplift with minimal engineering effort.

The Holiday Readiness Playbook is a 6-week tactical guide that helps e-commerce teams optimize systems, streamline user experiences, and accelerate infrastructure ahead of peak Q4 traffic. It provides actionable steps, checklists, and frameworks to boost speed, resilience, and conversions during the year’s most competitive shopping season.

Harper is a scalable, high-performance database for businesses needing system-wide flexibility. Vercel, in contrast, is a low-cost front-end hosting platform for developers focused on web deployment.

When performance and cost matter, Harper’s fused‑stack outperforms Heroku’s multi‑service architecture by orders of magnitude—at a fraction of the price

Page Cache delivers sub-second product pages by accepting your existing SSR or static framework, pre-rendering where it helps, and injecting dynamic attributes (price, availability, promos, personalization) at the last responsible moment—often hitting ~600 ms for 95% of users. Running on Harper’s unified platform, it serves fully formed pages from the edge with minimal code change, simplifying infrastructure while improving SEO, conversions, and global reliability.

Most apps start simple then accrete APIs, auth, caching, and realtime—Harper flips that by making your schema the app: define tables and relationships and you instantly get generated APIs, integrated caching, and pub/sub. This schema-defined approach lets teams prototype in hours and scale without glue code, extending with computed fields and custom APIs as needs grow.

Harper lets teams pre-render pages for global speed while keeping prices, inventory, and promos live by storing fast-changing values as lightweight attributes and injecting them at request time. By unifying database, cache, messaging, and runtime in a distributed platform, it removes ISR/API complexity, avoids full-page revalidation, and delivers static-level performance without rewrites or stack changes.

Early Hints let browsers start fetching critical assets before HTML arrives, shaving precious time off metrics like Largest Contentful Paint — even if Safari hasn’t caught up yet. With support in Chrome, Edge, and Firefox, plus simple fallbacks for others, it’s a low-effort, high-ROI optimization that delivers real-world speed gains today.

Simplify e-commerce development with Harper’s unified architecture. Database, cache, and real-time updates all run in one high-performance system.

In the latest Harper SEO Series session, experts from SearchSide and Akamai explored how implementing Early Hints (HTTP 103) can dramatically speed up website load times and boost SEO performance. The session showcased a live demo where Akamai EdgeWorkers and Harper worked together to cut Largest Contentful Paint from 2.9s to 2.0s — proving that even fractional improvements in speed can lead to meaningful business gains.

When a user taps a link, Harper and Akamai work in tandem to instantly determine the optimal destination and start loading assets—before the page even begins rendering. By combining ultra-fast distributed redirects with Early Hints, this system delivers a seamless, high-performance experience that feels instantaneous to the end user.

This O’Reilly report explores how unified platforms combined with service fabrics transform distributed systems by reducing complexity, latency, and cost while enabling global scalability and resiliency. Through real-world use cases and migration strategies, it demonstrates how organizations can achieve faster performance, stronger reliability, and measurable business value.

Retailers no longer need to choose between site speed and data freshness. Harper’s new pre-rendering pattern injects dynamic attributes like price and availability into a static page shell at request time—delivering lightning-fast load times with real-time accuracy, all without re-platforming.

DEF CON is a vibrant, curiosity-driven hacker conference where Chris Nelson finds a welcoming community eager to share, teach, and explore the boundaries of technology together. From lock-picking to RF hacking with tools like the Flipper Zero, it’s a place to learn by doing—and to discover that hacking is more about understanding than breaking.

GraphQL streamlines API development by letting clients request exactly the data they need from a single endpoint, but its dynamic queries often shatter traditional caching, driving up origin fetches, egress costs, and latency at scale. By progressing from full-response caching to partial field-level caching, then adding event-driven replication and ultimately a decentralized edge data layer—as embodied by platforms like Harper—teams can reclaim performance and budget predictability without sacrificing developer agility.

Drew Chambers joined the EcomOps podcast to share what I’ve learned from years of helping leading brands scale digital commerce—from fast websites to customer-first storytelling—and how Harper is enabling that with breakthrough performance tech. We covered why milliseconds matter, why performance is a growth channel, and how enterprise teams can build infrastructure that scales with their biggest moments.
