The operating system for general contractors

Run your whole shop from one place.

Leads, appointments, the sales pipeline, and post-meeting follow-ups, all connected, so nothing slips through the cracks between the tools you've been duct-taping together.

The everyday chaos

Your business runs on six tools that don't talk to each other.

A lead comes in by text. The appointment lives in someone's head. The follow-up is a sticky note on a truck dashboard. By the time anyone checks the spreadsheet, the deal's gone cold, and you never even knew it was slipping.

Leads slip through the cracks

A missed text or a buried email, and a $90k job quietly disappears.

Follow-ups get forgotten

No system says "call this person back today." So nobody does.

The office is always guessing

What happened at the meeting? Did it sell? Nobody back at the shop knows.

One place to run the business

Everything from first lead to closed job.

No more stitching tools together. Kombinator follows the way contractors actually work.

Capture & manage leads

Every lead in one place. No one falls through.

The moment a lead comes in, it's captured, with the contact, the project, the source, and who owns it. Search anyone in seconds. See exactly where each one stands.

  • One searchable list of every contact, lead to client
  • Duplicate detection so the same lead isn't worked twice
  • Clear ownership, so everyone knows whose lead it is
Run the sales pipeline

See every deal's stage at a glance.

Drag a deal from one stage to the next as it moves. Know what needs attention today, what's gone quiet, and what's about to close, without asking a single person.

  • A visual board for leads, appointments, and sales
  • Stale deals surface before they go cold
  • Move a deal forward in one drag
Book & track appointments

Scheduling that syncs where your team already works.

Book an in-home from the contact, assign the right salesperson, and it lands on their Google Calendar automatically. Everyone sees the week at a glance, color-coded by who's running it.

  • Two-way Google Calendar sync
  • A team calendar, color-coded by salesperson
  • No more double-booked site visits
Post-meeting summaries

The office knows what happened, without chasing anyone.

Right after a meeting, the salesperson taps through a quick summary on their phone: how it went, the next step, when to follow up. The office sees it instantly. Nothing gets lost on the drive home.

  • 60-second mobile summary, built for the field
  • Auto-sets the next follow-up so it never drops
  • The whole team stays in sync, office to field
Works with what you already use

Fits your business. Doesn't fight it.

Kombinator connects to the tools your team already lives in, starting with Google Calendar, so appointments show up exactly where everyone already looks. More integrations are on the way.
