YC S26 — SaaS Challenger

Kill SAP.
Kill Coupa.
StandBuy.

The AI-native procurement OS for capex-heavy industrials. 83% of procurement bypasses the negotiated catalogue. We close the loop.

60+ field interviews · live deployment Jun 3 · €20M / year actionable savings

"Standalone version — min $600k/year. I can't take Coupa anymore, they're useless. They are not responsive and they are not up-to-date in terms of AI."

The 12-month plan
You renewed Coupa. Drop it at next renewal.

We start as your Coupa front-end via the Compass API. Field intake, agent, catalogue intelligence — all on top of what you already pay for. By month 12, Coupa is plumbing nobody opens. You don't renew. ACV cut by ~50%. The Notion-to-Confluence playbook, for procurement.

Month 0–3 · Coexist
Pilot on top of Coupa
StandBuy connects via Coupa Compass API. 1 region, 1 category, 90-day deploy. Field intake + matcher + buyer dashboard live. No infrastructure rip.
Month 3–9 · Capture
Workflows migrate
3-way matching, supplier portal, contract intelligence, RFQ engine ship inside StandBuy. Coupa becomes plumbing nobody opens.
Month 9–12 · Drop
Don't renew
AP / invoicing flow lands. Full procure-to-pay coverage in StandBuy. At Coupa renewal: don't sign. License budget freed. StandBuy becomes system of record.
No rip-and-replace. No 18-month migration. We sit on top, capture the workflows, then absorb the rest.

How it works
Three steps. Zero SAP consultant.
01
Field worker speaks naturally

On mobile, WhatsApp, or voice: "20m PVC DN100 Friday morning Lyon site." No forms, no desktop, no 15 clicks.

02
AI matches & routes in seconds

Parses spec, quantity, deadline, site, project. Matches negotiated catalogue. If no match — auto-RFQ to 5 qualified suppliers, responses parsed and ranked.

03
Procurement function learns

Every order feeds the intelligence layer. Catalogue self-updates. Buyers see 100% of spend. Negotiation briefs auto-generated. The loop closes.

What we build
Four modules. One OS.
Wedge
Field Intake Agent

Mobile, voice, WhatsApp. AI parses natural language → matches catalogue → 1-click order or auto-RFQ. 15 seconds. SAP takes 15 clicks and a desktop computer.

Wedge
LLM as primitive, not feature

Scanned supplier quotes, parallel RFQs, 3-way invoice matching — only reliable post-2024. Coupa shipped "Coupa AI" as a sidebar chatbot in 2024. We assume LLMs as substrate.

Moat
Distribution + switching cost

Code is no longer a moat — Claude Code clones any feature in a week. The moat is being first to embed in 50 industrial clients. Once their data is in, leaving costs more than staying.

Depth
60+ interviews. Not guesswork.

60+ structured interviews — field operators, procurement officers, strategic buyers — before a line of code. Then we built and deployed the system in production. Claude Code can clone our UI. It can't clone that.

The numbers
The migration window is open.

Open Source
The code is not the moat.
The data is.

Claude Code can clone any feature in a week. Keeping our procurement engine closed protects nothing and slows distribution. So we're open-sourcing it.

Our moat is the data that compounds with every client — supplier benchmarks, pricing intelligence, spend patterns across 50+ industrial operators. That can't be cloned.

GitHub (soon)
Open source
Procurement engine core
Field intake parsing, catalogue matching, auto-RFQ orchestration. Anyone can deploy it. The community builds the connectors.
Paid cloud
Intelligence layer + managed hosting
Cross-client benchmarks, pricing intelligence, supplier risk scores. Gets smarter with every client. This is what you pay for.
