Unglamorous but Lucrative: Procurement Platforms Are Minting Unicorns

01 /The Concept

Every business's purchasing activity falls into two buckets: what goes directly into making the product, and everything else that supports the operation indirectly.

Take a company that assembles computers. The components are "direct" spend – they're baked into the cost of goods. The cardboard boxes, the packing tape, the paper in the invoices, the spare cables in the supply closet – that's all "indirect" spend.

The interesting part: companies obsessively track direct costs because they hit margins immediately. Indirect spend gets handled with much looser discipline – "just order some boxes" or "grab printer paper from the store around the corner"

Add it all up, though, and indirect spending can represent 10–15% of a business's revenue. Yet it typically gets reconciled after the fact in a spreadsheet or by reviewing corporate card statements – not the most rigorous planning or control mechanism.

Response is a platform for managing company indirect spend end-to-end.

The first function is centralizing the purchasing workflow. Companies load supplier catalogs into the platform, and all orders must flow through those catalogs. This enables complete visibility into indirect costs – broken down by category, department, amount, and other dimensions.

Every purchase request can run through a configured approval chain involving managers and finance. But approval chains can become slow, so Response also supports a rules engine: auto-approve purchases that fall within defined parameters – pre-approved product lists, spending caps, or employee category. The platform pulls employee category data automatically from an integrated HR system.

The rules engine itself can be tuned over time using Response's built-in analytics – including spend-by-person breakdowns and automatically updated market price benchmarks for different product categories.

Standard plans start at $599 or $999 per month, depending on headcount, number of locations, and the analytics tier.

The target customer is worth noting. Response isn't going after companies that just need to order office supplies – the ROI case doesn't work for those. Instead, it focuses on three segments where indirect spend is both large and complex: retailers with significant packaging costs, wholesale distributors running through pallets, shelving, and bulky supplies, and logistics companies with specialized handling equipment needs. Office supplies and electronics come along for the ride as secondary categories.

Response went through Y Combinator in 2020 and has now closed its first substantial funding round at $4.2 million.

02 /Why It Matters

At first glance, Response looks deceptively simple. But the startup's actual ambition is to build "the world's first digital procurement manager" – and the indirect spend platform is just the opening move.

A digital procurement manager would find suppliers, negotiate prices, and continuously analyze purchasing costs to optimize over time. The vision: describe what needs to be bought, and the platform handles everything else.

How an AI manager might negotiate with suppliers is an interesting design space. One approach is supplier auctions. That's the angle Crown ([related review](/review/uspej-sdelat-to-chto-i-tak-proizojdjot)) has taken – building an auction platform for procurement. Despite being at a very early stage, Crown raised €2 million in its first round this month.

The broader theme of automating employee-driven purchasing – indirect spend, in essence – is clearly attracting serious attention. Zip ([covered here](/review/rynok-gde-za-2-goda-mozhno-stat-milliardnoj-kompaniej)) is the benchmark: also a YC 2020 company, it hit unicorn status within two years at a $1.2 billion valuation. It has since raised another $190 million at a $2.2 billion valuation.

Response's own journey is also instructive. During the Covid outbreak in 2020–2021, the company supplied masks, gloves, and medical equipment to hospitals, building a first version of the platform to track its own supply chain. In 2022–2023 it expanded into general distribution – food to industrial equipment – and kept developing the platform. Now it has pivoted that supply-side platform into a buy-side procurement tool, embedding it into customers' business processes.

A similar arc played out at Ply ([covered here](/review/otlichnaja-mehanika-dlja-novyh-marketplejsov)), which initially raised $5.7 million for a construction materials procurement platform anchored by a marketplace. The marketplace is still there – but now it triggers when a contractor's inventory system detects that a material is running low.

The common thread: procurement tools can't live at the edge of existing workflows, requiring reminders and behavior change. They need to be embedded inside business processes as a natural next step – so the purchase just happens, and no one has to remember anything.

03 /Opportunities

The overarching direction is clear: building platforms that digitize procurement workflows.

This space may look boring, but it's large and growing. The market was $8.6 billion in 2024 and is projected to reach $19.9 billion by 2033. A solid, fat opportunity that many startups overlook precisely because the subject matter isn't glamorous.

The critical design principle, as noted above: these platforms need to embed into buyers' existing business processes so that using them feels like a natural part of the workflow – not something that was bolted on and requires constant promotion.

This principle applies even to traditional retail inventory purchasing, where automatic real-time price and geography arbitrage is increasingly possible. Several platforms are moving in that direction, as covered in a [recent review](/review/vykin-posrednikov-zarabotaj-sam).

The opportunity space here is genuinely broad. The question is which vertical to dig into – and which specific purchasing workflow, for which type of buyer, you could automate using the same integration-first principle.
