Point us at the bottleneck. We'll point you at the right next move.

Answer three quick questions. We'll steer you toward the best path: a strategy call, the ROI calculator, or a focused 57Seconds demo.

Step 1

What's hurting most right now?

The Problem

You've outgrown your tools. Now what?

01

Scattered data

It takes 20 minutes to find a basic answer. Your data lives in 6 different apps and nobody trusts any of them.

02

Expensive busywork

You're paying $50/hr humans to do $10/hr data entry — copying from one spreadsheet to another, every single day.

03

The Sarah problem

All institutional knowledge lives in one person's head. When Sarah's out sick, everything stops.

04

Apps that don't talk

Your CRM, scheduling tool, invoicing app, and comms platform all run in isolation. You're the glue.

05

Invisible online reputation

Your team delivers great service but nobody's leaving reviews. Competitors with worse service outrank you on Google.

06

The founder's trap

You built the business. Now the business runs you. You can't take a vacation without it breaking down.

What We Build

Software for how your
business actually works.

No templates. No bloat. Every system we ship is built specifically for you — scoped to your real operation.

Custom Web Apps

Dashboards, internal tools, and operations platforms built for how your team actually works — not how some template assumes you do.

🔄

Workflow Automation

Automated lead routing, invoice generation, status updates, and reporting. Remove the manual steps that slow your team down every day.

🏠

Client Portals

White-labeled login experiences that make your clients feel like they're using enterprise software. Build trust, reduce support calls.

🔌

Data Integrations

Connect your CRM, scheduling tool, billing system, and comms apps into a single source of truth. One place. One version of reality.

📈

CRM & Ops Platforms

Replace the pile of spreadsheets with a real operations system. Track leads, manage pipelines, generate reports — without ever opening Excel again.

How We Work

No mystery. No long timelines.

01

Discover

We map your workflow, find the exact bottlenecks costing you time and money, and define what the solution needs to do. No sales pitch — just clarity.

02

Build

We build a lean, custom solution scoped to your real needs. No unnecessary features, no off-the-shelf templates — just software your operation actually requires.

03

Launch

Your system goes live and saves time from day one. Full documentation and training so your team runs it without depending on us forever.

Mutual Fit

Some projects move fast. Some should wait.

The best engagements start with a clear bottleneck, an owner on your side, and a first version that's worth shipping now.

Good fit

  • You can point to a real bottleneck costing time, revenue, or trust.
  • You want a sharp first release, not a giant 12-month rewrite.
  • Someone on your team can own feedback and decisions during the build.
  • You care about outcomes, not just buying dev hours.

ROI Calculator

Need the numbers before the meeting?

Use our custom software ROI calculator to estimate payback timing, see whether a lightweight build or deeper platform makes sense, and walk into the call with a sharper business case.

Run a 30-second estimate

Monthly waste $11,258
Annual opportunity $135,096
Suggested first move Hybrid build

Directional estimate only. The full calculator lets you pressure-test scope and payback more precisely.

Best for owners asking:

  • Will custom software actually save enough to justify the build?
  • Should we automate one workflow first or replace the whole process?
  • How fast could this pay back if we get the scope right?

Common Questions

Straight answers. No fluff.

Do you work with businesses outside of Sonoma County? +

Yes. We work with businesses across the Bay Area and beyond. Most engagements start with a Zoom call, so geography is rarely a constraint.

What does a custom software project typically cost? +

Most projects run between $5,000–$25,000 depending on scope. We don't do hourly billing — we scope a fixed deliverable and price it upfront. No surprise invoices.

How long does a project take to ship? +

A focused automation or web app ships in 4–8 weeks. We give you a realistic timeline upfront — before you sign anything.

Do you integrate with Salesforce, QuickBooks, or Google Sheets? +

Yes. If it has an API or webhook, we can connect it. Common integrations: Salesforce, HubSpot, QuickBooks, Calendly, Twilio, and Google Workspace.
