Engagements

From noisy lists to a pipeline that runs itself.

Klarsparrow builds the outbound and intelligence systems that growing maker brands need: clean data, campaigns that actually land, and configurators that capture intent before a buyer ever emails you. Four engagements, defined scope, fixed price.

Inbound: scattered, unverified Outbound: clean signal

Five ways to work together

Each engagement is a fixed-scope build with a defined deliverable. Most clients start with one and layer the next.

These are fixed-price engagements, not hourly billing. Every one carries a defined scope and a defined timeline, agreed before work starts — you know the number up front, and there are no surprise invoices at the end.

Custom CRM Build-out
Built to how your business actually operates — not a template with your logo on it
  • Custom pipeline stages and deal/contact architecture mapped to your real sales process, not a generic template
  • Conditional, multi-step automation — branching logic based on customer behavior, not just "send email when X happens"
  • Role-based dashboards so ops, sales, and fulfillment each see what they need
  • Wired into your existing stack — payment processor, inventory, email — not a walled garden you have to migrate everything into
  • You own the system outright when it's done. No per-seat SaaS fee forever.

Note Prices are starting points. Final scope and figures are confirmed after a short discovery call — no engagement begins until you've seen exactly what's included and what it costs.
Context Comparable scope through a larger team — custom data infrastructure, deliverability systems, e-commerce configurators — typically runs significantly higher, with more overhead and less direct access to the person actually building it.

What this runs on

The platforms and APIs these engagements are built on — hands-on, in production.

Shopify
Built directly on the Admin API, not just theme edits: inventory sync, cost tracking, safe product imports.
Klaviyo
Programmatic campaign builds, segment logic, and multi-list audience management through the API, not the drag-and-drop editor.
Supabase / Postgres
Row-level security, service-role API proxies, schema migrations — backend work built to hold up under real traffic.
Anthropic Claude & Google Gemini
AI-assisted drafting and image-generation pipelines built on the official SDKs with custom prompting, not off-the-shelf plugins.
Fly.io
Containerized deploys and scheduled workers running the automation layer in production.
Custom CRM
A purpose-built outreach system: AI-drafted personalized email, contact and pipeline tracking, and cooldown-aware sending that protects deliverability.
