Apps · Operations · Growth

We build the
software, operate
the systems, and
structure the growth
of modern businesses.

We are the mainline between your business and the systems that run it.

Mainline is a national B2B studio for executives who treat software, sales operations, and growth as one system, not three line items. We engage selectively. We ship outcomes, not decks.

What we ship

Four services.
One Mainline.

We are the mainline that wires the whole stack — and threads AI through every surface.

Web, apps, CRM, AI — each priced flat, each shipped fast. Pick one, or take the bundle and watch them compound. Most agencies sell each separately at premium rates. We ship the whole stack at the prices below.

When you take all three

Web + App + CRM =
your business, end to end.

Most agencies sell each piece in isolation. The site doesn't talk to the CRM. The app doesn't share data with the site. Mainline ships the whole stack so the same customer shows up in every surface — and the AI threading through it knows them in all three.

The full loop · prospect → customer → return

  1. 01web

    Prospect lands on your site

    Your Web build is the front door. Iris Lite answers their pricing questions. They submit the contact form.

  2. 02crm

    Inquiry drops into the CRM

    PipelineIQ auto-creates a contact, scores the lead, routes it to the right rep. Iris drafts the first reply in your voice.

  3. 03app

    Customer opens your app

    Once they're on board, your Apps build (PWA or native) is where they live. Push notifications, accounts, payments, support.

  4. 04crm

    App activity flows back to CRM

    Every action in the app — payment, message, support ticket — appears on the Contact's timeline. Iris flags churn risk before they leave.

And the loop continues — repeat customer, referral, expansion

The integration moments

Six places where the stack does work no individual service can do alone.

  • Site form → CRM contact, instantly

    Every inquiry on your Mainline website auto-creates a contact in your PipelineIQ tenant with the right rep as owner. No Zapier, no manual import.

  • Stripe payment → CRM deal-won

    When someone pays in your app or website, the deal flips to 'won' in the CRM, the commission row auto-creates, your reviewer email fires — all without you touching the dashboard.

  • CRM segment → push notification

    Filter your CRM contacts to a segment. Iris drafts the notification copy. Your app fires the push. Customers who haven't opened the app in 30 days get a personalized nudge in your voice.

  • Iris reads your everything

    Iris in the CRM has full context on a contact's web visits, app activity, support history, and deal status — all in one timeline. Reps stop hunting for info, start responding.

  • One AI brain, three surfaces

    Iris Lite on the website (answering prospects). Iris in the CRM (running the pipeline). AI features inside your app (search, chat, generation). Same Mainline knowledge base. One voice.

  • Iris-powered content editor

    After launch, edit website copy, app screens, and CRM templates from one in-browser editor. Vercel auto-deploys. The whole stack updates without touching code.

The full business solution

Web + App + CRM, shipped + integrated,
for less than one big agency's discovery phase.

Take the trio. Site at $799 · App at $1,299 · CRM at $85/seat. Every piece pre-wired to talk to every other piece. Iris threads through all three. Most teams could replace four vendors with this stack and a single point of contact at Mainline.

One brief. One proposal. One lead.

How we work

Operating principles,
not a sales pitch.

01

Outcome over hours.

Our engagements are scoped to outcomes — pipeline routed, app shipped, system operating. We don't bill by the hour; we bill the result.

02

Senior on every engagement.

Every Mainline engagement has a senior operator on it. Junior staff support, but you'll always be talking to someone who's done this 50 times.

03

We hold the keys.

On retainer we get production access. We don't ship recommendations — we ship changes. You get the time back to focus on the work only you can do.

04

Selective by design.

We take twelve clients at a time, no more. If we're not the right fit, we'll tell you on the first call and point you somewhere that is.
