● Built by a coach, for coaches

Win more,
intelligently.

Finding the wins hiding in the numbers.

Swingle Sports Analytics turns match data into starting lineups, coin toss calls, and point-by-point answers, so you spend your timeouts coaching, not guessing.

Z1Why Swingle Sports Analytics

Every point matters. Every rotation matters. Every decision matters.

Our software gives coaches the analytics they need, without burying them in noise. Whether you run a high school program, a club team, or an NCAA roster, Swingle turns raw match data into calls you can make on the bench.

01 / Rotation Indoor

Find the six-rotation order that actually scores the most points, backed by your own match data.

02 / Coin Toss Beach

Know whether to serve or receive before the first whistle, based on your team's real history.

03 / In-Match All products

Read momentum and matchups in real time, fast enough to use during a 30-second timeout.

04 / Post-Match Indoor + Beach

Turn box scores into the story of why you won or lost, and what to fix at the next practice.

● Our mission

A club coach in rural Japan deserves the same analytics as a Division I staff.

You shouldn't need a data department, or a PhD in statistics, to know which rotation gives your team the best chance to win. Elite-level analysis, for every coach, everywhere.

Start in your strongest rotation

GASA tracks point-scoring percentage, sideout percentage, and rotation efficiency across your season, then tells you which of the six rotations to open in and where to stack your subs. No more guessing at the coin toss table.

Make the right call before the first whistle

Winning sometimes starts before the first whistle. Side or Serve weighs the receive-first advantage against current wind conditions to tell you which call, side or serve, actually wins you the set.

Volleyball Point Detective™

Find out which phase is losing you matches

Every rally becomes a fast four-tap sequence: who served, what happened on the serve, did the first attack convert, who won the point. No stat sheets, no film software, no screenshots. Just live taps that build a complete point-by-point record as the match happens.

Most teams know the final score. Few know why. Point Detective splits the match into terminal serving, first ball kill, and transition, then shows you which phase is actually deciding your outcomes, rolled up by set, match, and season, so practice time goes toward the real problem instead of a guess.

Z5Where the thinking happens first

Research first. Product second.

Before an idea becomes a feature, it's a hypothesis tested against real match data, written up in public.

● Coach Swing on Substack

Serve Triangle research, rotation math, coin toss theory, and the occasional argument with conventional coaching wisdom. All of it written up before it ever ships as software.

Brian Swingle

Founder & CEO

Brian founded Swingle Sports Analytics after three decades on the volleyball sideline convinced him that coaches needed software built for coaching decisions, not just stat collection. He's coached state kill leaders, called matches as a PA announcer, and manually tracked rotation data on spreadsheets since 2004, the habit that eventually became GASA. His mission is simple: help coaches win more through intelligent analytics.
