Grow accounts
without growing headcount.
Spar runs the per-client grunt work (audits, test ideas, mockups, code, QA, weekly digests) so your team can carry more retainers without hiring more people.
Start with a pilot on one client store. We work out partner terms on the call.
The math on agency growth is brutal.
Most CRO retainers cap out at three clients per strategist. The wall isn't strategy. It's everything around it.
Every new retainer is a week of audits from scratch.
Heuristic checklists, Loom walkthroughs, copying screenshots into a deck. Your strategists do the same week-one work for the third time this quarter.
Every variant waits on a designer and a dev.
An idea is cheap. A figma mock plus production-safe JS is not. The bottleneck isn't ideas. It's the people who can ship them.
Fridays disappear into status decks.
Weekly status decks for eight+ clients eat the day your strategist should be thinking about the next test rather than formatting last week's chart.
Every retainer in one workspace.
Switch between client stores in one click. Each one keeps its own audits, backlog, live tests, and learnings. Spar drafts a Friday digest for every store automatically.

Mockup of the agency workspace. Numbers and client names are illustrative. The layout and feature set are real.
The per-client costs Spar cuts.
Context switching, onboarding audits, designer and dev hours per test, weekly report decks: the work that forces you to hire as you add clients.
Per-client workspaces
Each store keeps its own audits, backlog, learnings, and integrations. Switching clients is one click, with no context-rebuild.
Audits in minutes
Paste a URL. Spar profiles the storefront, ranks every gap against a rule library tuned to ecommerce, and hands back a prioritized backlog.
Test ideas with mockups and code
Every idea comes with a visual mockup and production-safe JS your team can review, edit, and ship. The designer and dev step doesn't disappear. Spar just does the first 80%.
Shareable client reports
Frozen, share-link snapshots your clients open in a browser. No Spar account needed. Six default sections: intro, executive summary, health score, what changed, key learnings, CRO priorities.
We don't ship an off-the-shelf agency tier.
Spar pricing is per-client store. Most agencies want something different: bulk economics, white-label considerations, who pays, who gets billed when a client churns. So we do that on the call.
Bring your retainer model. We'll work out terms that don't break it.
- How you charge clients today, and how Spar maps onto that model without double-billing them.
- Bulk economics across the number of client stores you actually run, rather than a public rack rate.
- Workspace structure: one agency workspace with client stores inside vs. separate tenants per client.
- What happens to a client store when they churn from your retainer.
- Whether the client sees Spar branding or yours in shared reports.
Spar for other kinds of team
Each one says, plainly, what Spar does for that shape of work and which plan it lands on.
Founders
One store, no growth team, lots of leverage on $500.
In-house ecommerce
Lean DTC team. Spar carries the audit, idea, and mockup load.
Shopify Plus
Procurement-ready, DPA on request, founders in Slack for 90 days.
SaaS teams
Pro for small teams, Enterprise once SSO and a custom credit pool matter.
Run more retainers. Not more hires.
Start with a pilot on one client store. We'll show you the audit Spar produces in minutes, then how the workspace looks once you've got eight of them in there.
