What if GPS could track indoors, underground, and outdoors? and what if it worked without needing any external hardware, like satellites or beacons? and what if it was unjammable, on-device, and offline-capable? that's what we're building at Juxta — now backed by @ycombinator

@JulianAndreone Mogging

Legend & me.

@Whatdidyousay82 @JulianAndreone @DropSiteNews @lily_efranks @PabloReports @prem_thakker @MattLaslo hope you enjoyed your DEI mvp 👍

@byjohnf @JulianAndreone @DropSiteNews @lily_efranks @PabloReports @prem_thakker @MattLaslo More grammar errors in a tweet, than Ravens Super Bowls or Lamar playoff wins.

It’s our @DropSiteNews intern Lily Franks’ last week on Capitol Hill. Everybody please go follow her @lily_efranks, where she’ll be reporting from Ohio on local races and community issues. Shoutout to @PabloReports, @prem_thakker, and @MattLaslo for being amazing.

@Whatdidyousay82 @JulianAndreone @DropSiteNews @lily_efranks @PabloReports @prem_thakker @MattLaslo more typos in this tweet than bills superbowls

@JulianAndreone @DropSiteNews @lily_efranks @PabloReports @prem_thakker @MattLaslo Haha, you probably thought that was a cleaver comeback. Go back to your nazi clown show that funded by foreign money.

@JulianAndreone Goated

You have HOW many followers?

steve kerr is the nba equivalent of john harbaugh. carried by great players, game's passed him by, terrible lineup choices, and is so passive after every major loss

@amm_chino @JulianAndreone You must live in a very interesting part of California

@byjohnf @JulianAndreone I’ve seen Mahan ads 3:1 over Steyer on local TV. And for him to be losing this bad adds to his soulless vibe.

Matt Mahan is polling at 3%, but because the donor class and Big Tech are supporting him corporate media is platforming him over Democratic candidates polling far ahead. Notice how the establishment shoves these candidates down your throat.

@MaxXWilliamson @saranormous Thanks for thinking of us! We don’t do drones as much, mostly work on tracking assets/equipment/personnel/etc just using IMU

@saranormous @byjohnf maybe?

who do I know that is working on indoor drones, gps denied

most obvious lamar food poisoning game ever

super bowl has never been more guaranteed

@JulianAndreone @TomerAzarly Nobody on the clippers is taking a charge like goat luka. Big difference.

@TomerAzarly He does this like every game and never gets fined but if a Clipper says a single curse word they’re suspended 600 games

Did Luka Doncic just signal what I think he signaled with his hands? 😬

@JulianAndreone @JoeyB Best tweet of yours

The only way out is to demand a trade to the Indianapolis Colts, @JoeyB.

Tyler Loop is a first ballot HOF Raven.

@CookedByLJ8 when you'd see this or the harbaugh face on the sideline you knew we're done

how watching the rest of the game feels after they cut to the sideline camera of lamar slamming his helmet

@Celesteamadon 🐐

Known is finally live on the App Store. San Francisco feels a little different this morning. For the past few months, we’ve been building a new kind of dating platform for the post-swipe era.  Known is intentional, designed to get people on real dates. Love is coming.

YC founders notice who asks early and who doesn’t. John (@byjohnf) of Juxta didn’t fully believe investors really talked to each other. Then fundraising started. Once a few checks came in, the strongest investors reached out fast and pulled meetings forward. That wasn’t random. The most proactive investors were also the highest-rated ones. Foresight is part of the job.

Indoors is the real world, and GPS barely works there. Most of the world’s movement doesn’t happen in open skies. It happens indoors, underground, and inside dense cities. GPS struggles there because the signal hitting Earth is tiny and candle-flame weak, so it can’t penetrate walls or rubble. John Ferrara (@byjohnf) of Juxta wants to democratize location in those spaces, so tracking and forecasting works where it actually matters.

90% of human movement is invisible to GPS. That’s not a fun fact. It’s a trillion-dollar blind spot. Juxta is a no-hardware GPS alternative that works indoors, underground, in warehouses, and in war zones. While most founders chase ARR, others chase impossible problems. YC S25 solo founder, John Ferrara (@byjohnf) chose the second path, building a GPS alternative for places GPS can’t reach. In this episode, we break down: • why GPS is basically a candle flame • real traction in logistics + defense • raising $5M at a $40M cap in ~48 hours • what YC is really like as a deep-tech solo founder 🎥 Watch the full episode here: youtu.be/QBFO_J4a59U

Today we're launching Meteor v2. Our new agent ranks #1 on webvoyager (96.5%) beating openai, gemini. We can now run for 10x longer than before allowing us to complete more complex tasks. Go to browse.dev to download!
