Topsort vs. Zitcha.
Zitcha is built around retail media operations and workflow management. Topsort is the decisioning infrastructure underneath, running auctions, relevance, pacing, optimization and measurement across every commerce surface.
Topsort
The commerce media operating system: real-time auctions, catalog-aware relevance, AI optimization, advertiser self-service, offsite and in-store activation, and closed-loop measurement in one platform.
Zitcha
A retail media operations layer focused on planning, booking, collaboration and reporting workflows between retailers and their brand partners.
Built for different ambitions in commerce media.
Topsort Commerce media infrastructure | Zitcha Retail media workflow and operations | |
|---|---|---|
| Built around | Decisioning and monetization infrastructure | Retail media operations and workflow management |
| Auction and ranking | Native real-time auction with sub-5ms decisioning | Often depends on an underlying ad serving layer |
| AI | Bidding, pacing, relevance, ranking and yield optimized continuously | Workflow automation and planning support |
| Channels | Onsite, offsite and in-store in one decision layer | Campaign planning across channels, execution varies by stack |
| Operating model | One system to run and grow the media business | A collaboration and management layer over existing systems |
| Best fit | Teams who want to own decisioning, data and economics end to end | Teams whose main gap is planning and brand collaboration workflow |

Choose Topsort when
- You want to own the auction, the data and the economics rather than layer over a vendor
- Relevance and yield optimization matter as much as workflow
- You are consolidating decisioning, demand and reporting into one system
- You need one decision layer across onsite, offsite and in-store
Zitcha may fit better when
- Your ad serving is settled and the gap is planning and brand collaboration
- You primarily need booking, approvals and shared reporting with brand partners
- Introducing new decisioning infrastructure is out of scope this year
Common questions.
Does Zitcha run the auction?
Zitcha focuses on operations and workflow, with core ad decisioning typically sitting in an underlying serving platform. Topsort provides that decisioning natively, so auction, relevance and optimization are a single decision.
Does Topsort include planning and collaboration workflows?
Yes. Advertiser self-service, agency workspaces, approvals and reporting are part of the platform, alongside the auction and optimization layer.
Can Topsort work alongside our current operations tooling?
Yes. Topsort is API-first, so it can run underneath existing planning tools during a migration and then consolidate once it is proven on live traffic.
