YC: Requests for Startups

Most of those take a lot more time and money than YC usually offers.

There are some opportunities in "New Defense Technology". Something like a low-cost replacement for the Javelin anti-tank missile based on off the shelf phone camera parts ought to be possible. Of course, once that's out there, every insurgent group will have some.

"Explainable AI" is really important.

"Stablecoin finance" is mostly how to make sure the issuers don't steal the collateral. Maybe the people behind the stablecoin have an explosive collar welded around their neck. If the price drops, it detonates. That might work.

"Applying machine learning to robotics" has potential. Get bin-picking nailed and get acquired by Amazon. Many people have failed at this, but it might be possible now.

"Bring manufacturing back to America". Is it possible to build a cell phone in the US?

"Climate tech" - think automating HVAC and insulation selection, installation, and analysis. Installers suck at this. See previous HVAC article on HN. A phone app where you walk around and through the building with an IR camera is one place to start. Map the duct system. Take manometer readings. Crunch. That's do-able on YC-sized money.

The is no practical reason why javelin costs the $$$ it costs post r&d which was completed in the early 1990s. The matrix and most other electronics in it are extremely basic and could be obtained off the shelve already like 20 years ago. The concept is already outdated anyway - just use a cheap drone

Some of zhe reason why a javelin costs what it costs:

- small production runs

- obsolete components

- obsolete production technology

- certification requirements

- continued support and design changes to account for the above

- the mandatory defence surcharge

From top of my head.

More or less all of these yes. I always found it ironic how the new Javelin is believed to be cheaper because the components are less mechanical and easier to source. The continued support especially. Military systems can be designed (and warrantied) to last decades if maintained properly - and that costs the big bucks.

During wartime, it may be better to design for a short lifespan. Build the seeker with ordinary AA batteries welded in instead of thermal batteries with a standby life of decades. If it's intended for Ukraine or Taiwan, skip the part temperature range that would allow the thing to sit in the sun for a year in Iraq. Seal up the unit and stencil it "NO USER SERVICEABLE PARTS INSIDE" and "USE BEFORE 2026-12-31". It will have been fired at the enemy long before then.

Considering that WW2 artillery shells were used all the way into th 70s and 80s, you might rethink that.

Ukraine is out of ammunition NOW. If the war suddenly ends and they have to dispose of warheads that will expire soon, that is a cost that can be paid. But more importantly for them is ammunition now, if that can be achieved by making the build process simple, it should probably be done.
