Demo day in 14 days: a day-by-day rehearsal plan

Two weeks before a demo day, the instinct is to run the whole pitch twenty times on the last night. This plan does the opposite: one behaviour a day, in a fixed order, with a checkpoint at the end of the first week and a graduation take at the end of the second. It is the schedule StageMirror’s 14-Day Founder Speaker Intensive is built on, and every day of it works with a phone and a stopwatch.

Why rehearse a pitch over two weeks, one thing a day

A 2013 review of ten learning techniques rated only two “high utility”, and distributed practice was one: as its lead author puts it for teachers, students retain knowledge and skills longer when they spread practice out than when they mass it, even for the same total time. A 2006 meta-analysis of 317 experiments, all on verbal recall, concluded that spreading learning over at least a day beats concentrating it in one session. None of this research is about pitching. It argues for daily sessions over one long night, and no further.

The other half of the design is one behaviour at a time. Ericsson describes deliberate practice as training focused on a particular task, often designed by a teacher or coach, with immediate feedback and repeated attempts. This plan borrows the focus and the repetition; its feedback is a take you watch back the same day, which is slower than immediate.

A large meta-analysis, as corrected in 2018, found deliberate practice explained about 14% of the differences in performance across music, games, sports, education and professions. Whether a room decides to fund you is not something a filler count can see.

Week one also holds the words still. Days 1 to 3 use the same script, so a change in filler rate or pace is your delivery moving rather than new material.

The 14-day pitch rehearsal schedule

Each day adds one behaviour to the ones before it. Count back so Day 14 lands a day or two before the event, leaving time to fix what the graduation take shows.

Baseline first

Day 1 corrects nothing. You record 60 seconds at your normal delivery and write down your filler rate and pace. It is the day that gives Day 7 something to be compared with.

Pace before pauses

Day 2 fixes the script’s word count, so the band of 130–160 words per minute becomes three clock checkpoints: a quarter of the words by 0:15, half by 0:30, three quarters by 0:45 (why the band sits there). It comes early because, as the programme frames it, speed is either something you set or something adrenaline sets for you. Day 3 swaps every filler for a silence longer than 1.5 seconds, aiming for 2 to 3 a minute at the pace you set the day before. How to stop saying “um” has the full method.

Open and close before the middle

Day 4 scripts the opening and the close word for word, the two windows the programme treats as memorable. The first fifteen seconds take one of five hook shapes (question, statistic, bold claim, story or vivid scene), the close is exactly two sentences, and the target in both windows is zero fillers. Day 5 adds one sentence of twelve words or fewer, said three times, to the lens rather than to your own face on the screen.

Body after voice

Day 6 brings the hands to navel height with open palms, the zone the programme calls the TruthPlane, on each return to that sentence, in a full 3-minute dress rehearsal for Day 7. The feet wait until Day 10, when two markers go on the floor at shoulder width and both feet stay inside them for the whole take. Hands and feet are both read by the camera, so they are estimates that depend on framing.

Structure after the checkpoint

Day 8 rebuilds the talk on a spine (the story spine, the Hero’s Journey or Sparkline) written as six sentences. Day 9 moves your pitch at the act breaks. The monotone flag trips when the coefficient of variation of your pitch falls below 0.12, and getting louder does not fix it.

Questions last

Day 11 gives each answer a shape, ADD (Answer, Detail, Describe) or PREP (Point, Reason, Example, Point), with questions drawn cold from shuffled index cards. Day 12 adds hostile questions, two seconds of silence before each answer, and acknowledge, bridge, point. They come last because a question takes the script away, and as the programme puts it, filler “lives in the run-on section of an answer”. Answer, then stop talking covers the technique.

Day 13 trains nothing new: the talk is cut to two minutes and run once in the graduation’s exact shape, no restarts, with all your attention on the single number furthest from its Day 14 band. Day 14 is the graduation take: the two-minute talk to the lens, then two questions drawn blind from five written on folded slips, each answered with a pause, an acknowledgement, a bridge and your point.

The Day 7 checkpoint and the Day 14 graduation take

Day 7 is one unrepeated 3-minute take, scored on 8 items with a pass at 6. Day 14 has 12 items and passes at 10. The bars tighten between them, and Day 14 adds story structure, vocal variety, posture and sway (both camera estimates), and a question handled with a bridge.

A missed bar does not lock you out. Banking the day moves you on whatever the rubric says; the rubric is a separate pass over the same take.

How to rehearse your pitch with a phone and a stopwatch

• Warm-up. Before each take, 2.5 to 5.5 minutes of breathing, voice, articulation or posture work, with a tongue twister on most days, said at more than one speed.
• Set-up. Phone at eye height, about an arm and a half away, head and both hands in frame, light in front of you. Same spot every day.
• Counting. Tally the fillers and count the words. Filler rate is fillers divided by words; pace is words divided by the minutes from your first word to your last, pauses included.
• Pauses. Count the silences as long as a slow “one thousand one, one thousand two”, about two seconds; time it once on the stopwatch so you know it clears 1.5.
• Review. Watch each take three times: sound off for the body, picture covered for the voice, then everything. Tick your own boxes before anyone scores you.
• Milestones. Tick the Day 7 and Day 14 items honestly; eye contact and posture judged by eye are guesses.

The weak point is the counting. It is slow, you are likely to miss the fillers you did not know you had, and from Day 6 every take is aimed at the full 3 minutes. That part is worth handing to something else.

What StageMirror adds, and where it runs

The phone app and the web both run all 14 days: each day’s timed warm-up, the take, the readout, and banking the day with its reflection questions. The phone plays a take back only on the recording screen, straight after you record it; watching a stored take again, and scrubbing to a timestamp, is on the web. On either, a take stops at 3 minutes, and every day’s take is written to fit inside that, answers included.

The readout counts filler rate, pace, pauses longer than 1.5 seconds, and pitch variation with a monotone flag. The camera estimates (eye contact, TruthPlane, posture and gestures) each show how much of the take the camera could read. Each coaching point has to quote at least three words you said, or cite a moment inside the take. Points that cannot are dropped, and you are told how many.

On the web only, for now:

• Three-pass review. Pass 1 starts muted, pass 2 hides the picture, pass 3 is everything, and the AI’s estimate for each pass stays hidden until you finish it.
• Scoring the Day 7 and Day 14 rubrics.
• Tongue-twister accuracy, scored from your audio on days whose warm-up has one.
• The Q&A Gauntlet, which draws the questions for you.

The Intensive is not behind Pro. Free analyzes 5 takes a month, and your first Day 7 and Day 14 takes do not count against that, once each per calendar month (a re-record or a same-month restart pays from the allowance). When the allowance runs out you can still record and bank the day. Free recordings stop playing on the web after 7 days, so watch each take back the day you record it. The Gauntlet draws on the same 3 practice conversations a month as investor roleplay. Pro lifts both caps and keeps every recording playable on the web for its whole retention window. On the web it is $18.99 a month; in the phone app, the app store sets the price and shows it before you buy.

None of it can tell you what a room of investors will think. It counts what you did today, so that tomorrow’s take has one number to aim at.
