Why teams call us

Where off-the-shelf software runs out of road

  • Operations held together by spreadsheets and tab-juggling

    There's a Google Sheet that has to be updated every Monday, a CSV exported from one system and pasted into another, and a person whose job is half copy-paste. That's the work a custom tool replaces.

  • A workflow no SaaS quite fits

    Intake, document handling, scheduling, approvals, billing — your real flow rarely matches the way any product was designed. We build the system around how your team actually works, not the other way around.

  • An internal admin behind the website nobody loves

    Most marketing sites have a back office that the team avoids. We design the internal surface with the same care as the front-of-house — dashboards, queues, audit trails, and access control included.

What we build

Web apps, internal tools, and SaaS platforms

We do the discovery, design, build, and ship work end to end. That can be a single internal tool for one team, a customer-facing portal wired into your existing stack, or a full multi-tenant SaaS foundation. One team accountable for the whole engagement.

Proof

  • 3Specials — founder-built product, end to end

    3Specials is a 3sixs founder-built product covering web, mobile, maps, messaging, redemption, billing, compliance, and analytics. The same team that scopes your engagement built it from zero to production.

Frequently asked

  • What does a custom software engagement usually look like?

    A short discovery and design sprint to pin down the actual workflow, a written scope with a budget range, then a build phase that ships in working increments rather than one big launch. You see real software early and we adjust as we learn.

  • How long does a Dallas custom software project take?

    Discovery and design typically runs in weeks. The build phase depends on integrations, data volume, and whether we're replacing an existing system. We estimate honestly during scoping rather than quoting a generic timeline.

  • How is pricing structured?

    Fixed scope, fixed budget range, written assumptions. After discovery you get a scope document that lists what's in, what's out, and where the cost is most likely to move. No open-ended hourly billing surprises.

  • Who actually writes the code?

    3sixs is founder-led, AI-native, and human-reviewed. The same team you talk to during scoping is the team that designs, builds, and ships. We don't hand delivery to an offshore subcontractor.

  • Are you based in Dallas?

    We're a Fort Worth studio serving DFW, including Dallas. We meet on-site when it helps and remote when it doesn't. Same metro, same time zone, same week.

  • Do you work with our existing systems?

    Yes — most engagements involve integrating with a CRM, an accounting tool, a calendar, an SMS provider, or all of the above. We design around the stack you already pay for rather than asking you to rip it out.

  • What should I ask for on the contact form?

    Tell us the workflow that's costing you time today and what good looks like once it's fixed. Don't worry about specifying the tech stack — we'll figure that out together during discovery.
