For CRO & growth agencies

One strategist. Eight client stores.
Friday recaps that write themselves.

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.

Friday is a deck-building day, not a strategy day.

Weekly status decks for eight+ clients eat the day your strategist should be thinking about the next test, not formatting last week's chart.

Multi-client command center

What Spar did this week

  • 12auditsacross 6 client storefronts
  • 47test ideas draftedwith mockups + JS
  • 9tests shippedQA'd before publish
  • 8Friday digestsone per retainer

Mockup of the agency workspace. Numbers and client names are illustrative. The layout and feature set are real.

Every capability earns its keep against one cost.

For each thing Spar does, here's the per-client cost it pulls toward zero. That's the unlock for headcount-light agency growth.

Per-client workspaces

Each store keeps its own audits, backlog, learnings, and integrations. Switching clients is one click, not one context-rebuild.

Pulls toward zero:Context-switching cost

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.

Pulls toward zero:Week-one onboarding cost

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%.

Pulls toward zero:Designer + dev cost per test

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.

Pulls toward zero:Weekly recap deck cost
Pricing, the honest version

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.

You get the founders, not a SDR. Bring your retainer model. We'll work out terms that don't break it.

30 minutes. Real terms.
What we'll cover
  • 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, not 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.

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.
