PIS7 — Precision Intelligence & Smart Tools
PIS7.com is an engineering-grade computational hub built for software architects, quantitative analysts, civil contractors, and technical founders who require fast, transparent, and mathematically verified calculators without spreadsheets or server-side data tracking.
Why We Built PIS7
Most legacy online calculators suffer from three critical flaws: undocumented black-box formulas, bloated server round-trips that capture sensitive user inputs, and US-only unit assumptions. At PIS7 Labs, we engineered a unified multi-silo platform that executes 100% client-side inside your browser across four native locales (English, German, Spanish, and Turkish).
Our Five Core Quantitative Silos
- AI, LLM & Cloud Infrastructure: VRAM sizing for quantized models, prompt-caching API token economics, cloud GPU vs. workstation CapEx break-even, and HNSW vector database memory sizing.
- Tax, Wealth & Corporate Finance: Pass-through corporate vs. sole-proprietor tax modeling, mortgage amortization vs. index compounding, inflation-adjusted FIRE, and SaaS LTV:CAC unit economics.
- Construction, Solar & Civil Engineering: Ready-mix concrete volume with subgrade spillage buffers, 100%-solids epoxy resin coverage, solar PV + LiFePO4 battery autonomy, and thermal BTU/kW HVAC load sizing.
- Client-Side DevOps & Network Tools: Cloud VPC CIDR subnet planners, Brotli/Gzip API egress bandwidth calculators, PostgreSQL tuple/B-Tree RAM estimators, and SRE SLA error-budget analyzers.
- B2B Software & Cloud TCO Comparisons: Transparent cost benchmarks comparing Zapier vs. Make vs. n8n, Stripe vs. Merchant of Record platforms, Vercel vs. Cloudflare Pages, and Auth0 vs. Clerk/Supabase.
