Upstream
32 SaaS layers, rebuilt as the slice you actually use. From $9K, on direct billing.
Replace expensive SaaS layers (Klaviyo, Datadog, Harvey, Salesforce, Workday, etc.) with custom builds on AWS / Anthropic / Stripe direct. Pick a single tool, a category combo, or your industry's typical stack. Wrapper margin reclaimed.
We don’t rebuild Datadog. We rebuild your usage of it — the 15–25% that’s on your renewal invoice but isn’t where the SaaS earns its margin. Per-seat / per-MTU / per-host pricing taxes the whole product even when you use a fifth of it. Our rebuild is calibrated to your actual surface area — mapped in the first 30-min call, before quoting.
- Dashboards your team opens daily
- Alerts that page on-call
- Integrations already wired up (Slack, PagerDuty, GitHub, etc.)
- Reports leadership relies on
- Workflows you’ve customised over the years
- The 2–3 user roles that matter (admin / analyst / viewer)
- Features another niche product does better (we’ll point you at it)
- Edge-case enterprise modules (SIEM, advanced compliance, etc.)
- AppExchange-style ecosystems we can’t replicate
- Years of vendor-built ML / heuristics tuned across millions of clients
- The 30 features your team has never opened (and never will)
- If our audit finds you ARE using the deep end, we’ll tell you straight: the rebuild won’t pay back. Stay on the SaaS.
If you're B2B SaaS, D2C, or a law firm, start here. Each ICP page has a curated combo recommendation calibrated to that industry's typical stack and spend.
