The Last Demo

Isobel Wickham was twenty-four years old and had spent the last eighteen months of her life answering phones at a dental clinic, which is why her hands were shaking so badly around the foam case in her lap that Neal, driving, kept glancing over.

"Breathe, Izzy. It's a pitch-off, not a firing squad!"

"It's a pitch-off with forty other teams and actual investors and free tacos, and I'm wearing the blazer I bought for your cousin's wedding!" she shot back. "The one with the missing button!"

"Nobody looks at buttons. They look at the prototype. Which works. Which we tested nine hundred times on the kitchen table while I burned every dinner we attempted."

That was true, at least. The sensor, a little white puck they called Hubby in the workshop as a joke that had somehow stuck, sat in its foam case on Isobel's lap like a sleeping cat. She had co-built the thing with her husband over fourteen months of weeknights, and until three weeks ago exactly nobody outside their apartment knew she had done any of it. Neal had done the boards and the firmware. Isobel had done the power architecture, the enclosure, the entire testing plan, and, as she liked to put it, all of the taste.

"You could still co-present," Neal said for the eleventh time. "We've talked about this. You don't have to fly solo on day one."

"And you'd stand there vibrating with stage fright while I talk? Neal, you fainted at our wedding rehearsal. During the vows. It was thirty seconds of vows."

"I was dehydrated."

"You were wearing a suit in July in Texas, sweetheart, that's a lifestyle choice." She squeezed his knee. "I want this. I want to find out if I'm more than a face at a front desk, and I can't find that out with my husband standing next to me going 'well, actually, the math was mostly me.'"

"The math was not mostly you, the math was entirely me, which is exactly why they need you up there." He grinned. "Go be brilliant. I'll hold the box."

The Ampère Labs accelerator occupied the second floor of a glass building on East 6th, all whiteboards and demo tables and a forest of little brass soldering stations, and the moment they walked in Isobel saw Francis Hobbs across the room and forgot how legs worked. Forty-five years old, silver at the temples, CEO of Ampère Labs, the man whose keynote she'd heckled with a question about battery chemistry at a conference last spring. He had answered it. He had actually answered it, for six whole minutes, and then asked her name.

"He's here," she hissed.

"Who? Oh. Hobbs. Okay, that's either great or terrifying."

"Both. Both, definitely both."

"Which table is yours?"

"C-14. Between a robot litter box and a company that makes fridge cameras, which, Neal, how is that a company?"

"Because investors are weird. Go set up. I'm going to find the coffee and figure out which of these people will talk to me about capacitors."

Setting up took twenty minutes because every passing founder stopped to ask what the white puck did, and Isobel discovered, with genuine shock, that she could explain it. Fast. Clearly. With jokes. A woman from a smart-lock startup actually laughed twice. By the time Neal wandered back with two coffees, Isobel had given the same pitch four times and had a small crowd, which she waved away with an apologetic little bow.

"Who are you and what have you done with my wife?" Neal asked.

"Your wife found out she loves this. That's who." She took the coffee. "Is that decaf? Why would you bring me decaf, I need my heart working."

"It's regular, relax. Katelyn Starr just walked in, by the way. Lead judge. She's the one who coached me through that disaster pitch three years ago, remember?"

"Remember? I held your hand while you drafted the apology email."

"Right. Well. Be nice to her. She remembers failures forever but she also funds people she likes."

The mixer started at six on the main floor, all forty teams plus judges and a handful of investors circulating with little name-tag stickers, and Isobel lasted eleven minutes before Katelyn Starr found her. Thirty-one years old, dark suit, the unhurried walk of a person who had never once needed to jog.

"Isobel Wickham? Wickham and Willoughby, table C-14?" Katelyn read the tag on her own sticker like she was confirming a reservation. "Your submission packet lists power consumption at forty milliwatts idle. That's a rounding error. Where's the catch?"

"The catch is there is no catch, which I know sounds like a catch," Isobel said, and then made herself slow down. "Sorry. Hi. The forty milliwatts is real because we don't do continuous RF wake. The puck listens on a passive infrared channel first, and the radio only spins up when the IR threshold trips. Most products do it backwards."

"Backwards how?"

"They wake the radio to decide if they need to wake the radio. Which is like calling someone to ask if you should call them."

Katelyn's eyebrow went up a quarter inch, which Isobel would later learn was practically a standing ovation. "And the false-trigger rate on the IR channel?"

"Under two percent in our test matrix. Nine hundred trial runs, three different room layouts, two pets, one toddler. The toddler belongs to our downstairs neighbors, and he is a chaos gremlin."

"You did the testing yourself?"

"All of it. Every run, every log." Isobel heard her own voice get steadier as she went. "The firmware is my husband's, the power design and validation are mine. We split it down the middle on purpose."

Katelyn glanced over Isobel's shoulder, clearly looking for the husband who had, at that exact moment, drifted off toward the robot litter box people. "So you're the one who answers the hard questions."

"It would appear so," Isobel said, surprising herself completely, because two minutes ago her hands had been shaking and now she was lecturing a venture partner about duty cycling. "Neal's brilliant, don't get me wrong. But he'll tell you the same thing. I'm the one who says no to bad ideas. He falls in love with ideas. Somebody in a two-person company has to be the immune system."

That got an actual short laugh out of Katelyn Starr. "Immune system. I'm stealing that."

"Steal it, I'll invoice you."

"Tomorrow you present alone, per your submission. Your husband is listed as technical support only. Whose call was that?"

"Mine," Isobel said, and did not mention that it had taken three weeks of negotiation, one crossed-arms standoff, and a solemn promise that she would text him between slides. "It was mine."

"Good. Forty-five seconds into day one, every investor in that room will figure out who the engineer is. Better they figure out it's both of you on your terms." Katelyn stuck out her hand. "Grill you harder in the finals, Ms. Wickham. Bring the toddler data."

"He's twenty-six months old, but yes, I brought the toddler data."

Katelyn moved off toward the fridge camera people, and Isobel stood there with her coffee going lukewarm in her hand, doing a slow turn to find her husband. He was easy to spot. He was the one man in the room gesturing at a litter box with both hands like a man describing a UFO sighting.

"Neal. Neal, come here, I need to tell you something before I lose my nerve."

He jogged over, all elbows. "What? What happened?"

"Katelyn Starr just grilled me for five minutes and I answered everything and she laughed. She laughed at my immune system joke and she's stealing it, and Neal, I didn't freeze. Not once. I sounded like someone who knows what she's doing."

"You are someone who knows what she's doing. Nine hundred test runs, Izzy."

"I know, but knowing it in the kitchen and knowing it in front of Francis Hobbs are different animals." She grabbed both his hands. "Also he's here. Hobbs. He's here, I saw him, and he hasn't seen me yet and I need you to tell me whether that's good or bad because I genuinely cannot tell."

"It's good," Neal said, squeezing her hands. "Iz, hey. Look at me. You asked a man a battery question once and he talked to you for six minutes. That was you being nervous. Tomorrow you get forty-five slides and a working prototype."

"Forty-five seconds per slide, and one of the slides is a picture of the toddler."

"Then we're unstoppable. Now feed me, because the taco line is out the door and I've been talking capacitors to a man who thinks solder wick is a personality trait."

Isobel laughed and let him tow her toward the food, and if her eyes drifted once or twice back across the room to where Francis Hobbs stood laughing with a judge, well. Neal noticed, and pretended he didn't, and ordered three tacos each.

The first-round demo happened the next morning at nine sharp, which Isobel considered a personal insult. Nobody alive should have to explain duty cycling to strangers before ten.

Her table was C-14, wedged between the robot litter box people on her left and the fridge camera people on her right. The litter box team had brought a life-sized plush cat. The fridge camera team had brought a fridge. Isobel had brought a little white puck, a folding table, a laptop, and a spiral notebook she'd decorated with a sticker of a lightning bolt at two in the morning because Neal told her presentation materials should have personality.

"You've got this," Neal murmured, plugging in the demo power strip under the table. "Nine hundred runs."

"Eight hundred and ninety-nine if I trip over this wire and die right now."

"Then I'll finish the presentation. It'll be the saddest pitch in Ampère history. Hobbs will fund us out of pity."

"Go away. Stand over there and be technical support."

He went and stood over there, technically.

The first three judges came through in a row, and Isobel found her rhythm almost by accident. Plug in the puck. Wake it up. Show the idle draw on the meter, forty milliwatts, let the number sit there while the judge's eyebrows did their work. Then the demo motion, the little wave of the hand that tripped the IR channel, the radio spinning up on cue, the app popping the notification. Fourteen months of weeknights compressed into a ninety-second routine, and she'd rehearsed it so many times on the kitchen table that her hands knew it without her.

Which is, of course, exactly when the hands betrayed her.

Judge number four was a woman with a clipboard and a permanent squint, and Isobel was mid-sentence about the passive infrared channel when her elbow caught the laptop cable and knocked the little connector half out of the port. The screen winked. The meter blanked. Somewhere behind her sternum, her heart attempted an escape.

"Oh no, no, no, hang on, one second, sorry, this never happens at home, I promise."

The squint deepened. The clipboard pen went back to work, and Isobel had exactly enough time to think, she's writing "fragile demo" in all caps, before a hand appeared under the table.

It didn't grab anything. It just held out the correct cable, the spare, the one with the reinforced boot that Neal had insisted on packing even though Isobel had said, and she could quote herself, "When am I ever going to need two cables, we're not running a rock concert."

She took it, seated it home, and the screen came back like nothing had happened.

"Sorry about that. Hardware. It keeps you humble." She glanced down, just for a second, into the shadows under the table where her husband was crouched behind the table skirt like the world's most qualified ghost, giving her a thumbs up the size of a dinner roll. "Where was I? Right. The radio never wakes up to ask if it should wake up."

She finished the pitch. The squinting judge even nodded at the end, a small economic nod, and wrote something that hopefully wasn't all caps. Isobel waited until the crowd between tables thickened, then leaned down under the table skirt as if retrieving her notebook.

"I love you," she whispered. "And we're buying a lifetime supply of that cable."

"Calibrated six of them before we left. Told you."

"You didn't tell me, you just did it, which is worse, because now I owe you forever."

"Married you for less. Go press the flesh, presenter."

By late afternoon the bracket board went up, forty teams whittled to sixteen, and Hubby was on it. Isobel found out because the litter box people cheered and pointed at her. By eight the next morning it was sixteen down to eight, and by two in the afternoon the board said FINAL FOUR, and C-14 was third from the top in letters that somebody had clearly gone out of their way to make big.

She stood in front of that board for a full minute, not moving.

"Excuse me, ma'am, you're blocking the bracket."

"I made the final four of a startup pitch-off, I'll block whatever I want."

"Oh, in that case, block away."

She turned. Neal was holding two coffees and grinning like the sun had gotten into him somehow. She grabbed his sleeve.

"Final four, Neal. Out of forty. We're in the final four of a thing, and Francis Hobbs is judging it, and I haven't even tripped on anything today."

"That I know of."

"That anyone knows of. Come here, I want to look at it from farther away, maybe it's a typo."

They did not make it to a better viewing angle for the bracket, because Isobel got about four steps down the hallway before the reality of it caught up with her, and then there was a supply closet door standing right there, propped open because somebody had been moving folding chairs, and Isobel did the sort of thing she would later describe to her sister as "very out of character" and "also completely in character, depends who's asking."

She hauled her husband into the closet by the sleeve and shut the door.

"It's dark in here," Neal observed.

"It's a closet, that's the whole concept. Neal. Final four."

"Final four."

"I presented alone. You sat there being technical support and I did the whole thing alone, and Katelyn Starr wrote down my toddler statistics, and I did not freeze, and I..."

"Isobel."

"What?"

"You were brilliant. You were so brilliant I got bored of watching and started watching the judges instead, and every single one of them leaned forward at the same point. The forty-milliwatt number. They all lean at that number, it's like watching a rowing crew."

"In the dark?"

"Obviously in the dark, I can't see you at all, I'm just talking at your general location."

She found his shirt front by feel and pulled, and that part was on her, one hundred percent, no jury would ever convict. But the
