Mainline Studio · A software studio

Software, plainly built.

We build apps for small service businesses. Some we own — like Lineup, our booking app for barbers. Some we build for our clients. Bootstrapped, founder-owned, no VC, no enterprise.

01 — What we build

Apps we own. Built one trade at a time.

We ship purpose-built SaaS for small service businesses — one trade at a time. Each app is sovereign: its own product decisions, its own pricing, its own roadmap. The agency builds the apps and lets them breathe.

Barber · Live In market

Lineup

A booking app for independent barbers. Public booking page per barber, client list, SMS confirmations, no-show tracking. Free tier, Shop $7.99/mo, Studio $14.99/mo.

Pallet

Inventory and dispatch for small logistics operations. Research phase. Sequence after Pitcrew ships and proves the multi-product thesis.

02 — Services

We also build for shops in niches we've shipped apps in.

Custom websites, ongoing retainers, and bespoke software for shop owners who need more than our products can give. Fixed-price, public on the site. No sales process, no proposals that take three weeks. Currently open to barbershop clients in Chicago; expanding as we ship more apps.

03 — How we work

No sales team. No proposals. No surprises.

01 — Public pricing

Every price, on the site.

If a buyer has to ask "how much," we failed — or the offer isn't ready to sell yet. Our prices are on the site. Tiers, retainers, one-time builds — all of it.

02 — Founders only

Tyler + Eric, start to finish.

We don't have a sales team. No SDRs. No account managers. You talk to one of us on the discovery call, you work with one of us on delivery, and you text one of us when something breaks.

03 — Fixed scope

We quote, you approve, we ship.

We give a fixed price and a fixed scope, in writing, after a 15-minute call. You say yes or no. If you say yes, you know exactly what you're getting and when you're getting it.

04 — Who we aren't

Some things we refuse.

05 — Next

Book a call or don't.

Fifteen minutes. We listen, you talk. If we're a fit, we quote verbally and follow up in writing with a price and a scope. If we're not, we'll tell you who might be.
