The challenge

Enterprises run performance management across a mess of spreadsheets, docs, and disconnected HR tools — reviews happen once a year and rarely change anything. Happy5 set out to make goals, work, and performance one continuous, AI-assisted loop.

Selling that to Indonesia's largest banks and telcos meant clearing a bar most startups never reach: enterprise-grade security, reliability at 50,000-employee scale, and a commercial story credible enough to close seven-figure, multi-year contracts.

What I led

  • Architected the flagship Enterprise SaaS platform, securing and retaining major contracts with BCA and Telkomsel — directly serving performance management for 50,000+ employees.
  • Spearheaded end-to-end ISO 27001:2022 certification with a zero-major-finding audit, clearing procurement for banking clients.
  • Migrated infrastructure to Kubernetes, cutting AWS costs ~50% (~$24k/yr) while holding 99.99% uptime.
  • Built and led a 45-person Product & Engineering org, achieving under 10% annual turnover with structured career ladders.
  • Partnered directly with sales on commercial strategy — bridging deep technical architecture with revenue.

The approach

Selling software to a bank is a different discipline from selling to a startup. The whole system has to earn trust before it earns the contract — so we built for the security audit, the procurement review, and the 50,000-employee load from day one, not as an afterthought bolted on before the demo.

That meant treating security and reliability as product features, not chores: ISO 27001 designed into the architecture rather than documented after the fact, infrastructure re-platformed to hold four-nines uptime while cutting cost, and an engineering org built to keep that bar as it scaled past forty people.

Enterprise trust isn't a feature you bolt on. It's how you build from the first commit.

The result

6.5×ARR growth ($200k → $1.3M)
$1.1M5-year enterprise contract
Zeromajor findings, ISO 27001

A profitable, VC-backed B2B SaaS platform trusted by enterprise giants — the kind of rigor Thirteen now brings to studios of every size.
