Built Things
Systems, software, and document-filing services designed for operational correctness and risk reduction.
This page documents systems and services built and operated by Sandeep Arneja. Across all of them, the common thread is the same: translating rules and requirements into repeatable, low-error operational processes.

Prior Founder & Exit Experience
Before operating LLC Publishers, I co-founded and scaled multiple software companies in the advertising and marketing technology space, each focused on building reliable systems that operated under real-world constraints.

Co-founder & CTO — Acquired by Integrate
ListenLoop was a B2B account-based marketing advertising platform. As co-founder and CTO, I led technology and product from early MVP through product-market fit and acquisition. This included building and scaling the core platform, managing production systems, working directly with customers, and leading the engineering team.

Cross-Cutting Operating Principles
Across all of these systems, the operating principles are consistent:
- Process correctness over speed
- Automation backed by verification
- Clear boundaries between execution and advice
- Documentation and auditability
- Risk reduction through systems design
These principles matter most in environments where mistakes are costly, requirements are explicit, and reliability is more important than novelty.
What This Page Is Not
- This page does not provide legal, tax, or accounting advice
- It does not describe consulting engagements or clients
- It is not a claim of exclusivity or full-time focus
- It documents systems built and operated, not opinions or recommendations
Each of these systems reflects the same approach: understand the rules, design the process, and execute with precision.
