## Question
What already exists on the buy side, the sell side, and in between — and is 'free for buyers, charge suppliers' actually novel?
---
Parent: #1
Buy side. Ariba, Coupa, Jaggaer, Ivalua, GEP SMART, Oracle Procurement Cloud, Workday Strategic Sourcing (ex-Scout RFP), Zip, and public-sector specialists (Bonfire/Euna, OpenGov, Periscope). All do full-cycle RFP issuance -> bid receipt -> scoring/award. Table stakes, not white space.
Sell side. Responsive (ex-RFPIO, $14k/yr), Loopio ($20k/yr+), Qvidian, Proposify, PandaDoc, plus AI-natives Arphie ($2.9M seed, General Catalyst), Rohirrim ($15–20M, Bessemer/IBM Ventures), AutoRFP.ai, Vendorful. Every one of them is drafting-only — none connect into the buyer's evaluation workflow. That gap is real; the 'help me write faster' wedge is crowded.
Who pays, and the resentment — the critical finding. Three distinct sub-models with very different reception:
Ariba-style threshold-triggered network fees (~15.5bp plus tiers): heavily resented, because it is imposed after the fact and the supplier cannot exit if their buyer mandates it. 15+ years of adversarial trade-press coverage. No organized legal action found.
Coupa-style zero supplier fee: explicitly built and marketed as the anti-Ariba, and used as a sales weapon.
ISNetworld/Avetta-style compliance-vault subscription (~$450–900/yr, contractors often paying 2–3 platforms): sustains real businesses for 20+ years, but a 2024 AGC study found 38% of subcontractors cite the fees as an enrollment barrier, and it prices out small and diverse firms. A cottage industry markets against it.
Public-sector software has trended the other way — Euna, OpenGov, and Periscope all advertise free to bid; Euna's supplier Pro tier is $50/yr.
Retail reality. No common rail exists. Walmart: Coupa for NA third-party spend plus a homegrown Bamboo Rose Enterprise Sourcing Platform. Target: Partners Online (40+ apps) with EDI via SPS Commerce. Kroger: Supplier Hub with a Prospect Vendor gate, Oracle-adjacent. Costco: no software-mediated process — buyer relationships only.
Strongest white space. A vendor selling into all four maintains four relationships, four compliance packets, four portals. Nobody offers one profile -> many retail buyers. Secondary: retail-category-specific bid evaluation AI is underserved — Keelvar and Ivalua optimize generically, not for private-label cost structures or category management.
Competitive pattern to respect. Independent AI matching startups are not dying, they are being absorbed: Scoutbee -> Coupa (Oct 2025), TealBook -> Supplier.io (Apr 2026). Incumbents treat matching AI as a bolt-on to defend the platform.
