The 2140 Foundation was announced in 2024 (#717235) but 2025 was their first full year in existence. Yesterday, they published their 2025 Annual Report.

If you are like me, you may have forgotten what distinguishes them from the now many other bitcoin developer support foundations out there (spiral, brink, chaincode, localhostresearch, opensats, who am I missing?). This is how they describe themselves in the report:

We've built a European hub in Amsterdam that provides Bitcoin developers with multi-year employment, a physical office for collaboration and mentorship, visa sponsorships for global talent, and the community support necessary to prevent burnout and build sustainable careers.

And this is their tl;dr of what they accomplished this year:

• Secured multi-year funding to operate sustainably;
• Hired four talented developers (Rob, Novo, Sadiq, and Sergi) making meaningful contributions to Bitcoin Core and critical infrastructure;
• Opened our office in the heart of Amsterdam, conveniently accessible by public transportation;
• Received regular in-office visits from people across the Bitcoin ecosystem, both local and international, including Lightning Labs, Blockrise, Brink and many more;
• Successfully sponsored work visas from emerging markets, bringing developers from Nigeria to the Netherlands;
• Hosted our first in-person development week with developers from around the world, and established regular programming (monthly show & tell, BitDevs);
• Developed Silent Payments, Kyoto, and BlockTemplateManager, made technical contributions to various projects including SwiftSync and libbitcoinkernel, and did significant multiprocess work on the new mining interface.

The 2140 Foundation was founded by Josie Baker and Ruben Somsen:

Initial funding came from OKX, Xapo, and OpenSats.

Looks like in 2025 they filled out their team with Novo, Rob, Sadiq, and Sergi and Emily (for whom I couldn't find any socials).

Their major technical projects in 2025 were:

• Silent Payments
• IBD Performance and SwiftSync
• Kyoto BIP-158 client
• contributing to libmultiprocess
• new mining interface for Core (BlockTemplateManager)
• contributions to libbitcoinkernal

You know it's an interesting project when you have to spend 10 minutes reading about each of the things they worked on in order to wrap your head around it. Pretty cool!
