Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.

Consumer Lab does this testing. It's great, you just have to pay for a membership.

I started a company to grow unlimited eggs from stem cells, based on the work from my recent PhD. This will solve nearly all female infertility and help prevent genetic disease. https://ovelle.bio

Best of luck. I've known so many people in my circle deal with infertility and miscarriages. Hope you succeed.

"Google maps but for old maps": https://pastmaps.com This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS . It gets ~80K MAUs and just slowly and consistently is growing o…

Hey, cool to see!

I'm running a similar but smaller project (5k MAU), my oldest map is central London in 1561

https://onamap.me/maps/London1561/

I got into it because I was interested in the technical challenge of registering GPS to maps which are very warped compared to reality, like very old maps or illustrated tourist maps.

My home page is here for more: https://onamap.me/

I also came across this similar project a while ago:

Good luck continuing to build out the project!

I'm working on Listening Facts[0], a music habits visualization tool based on your top tracks. Inspired by Receiptify and every day nutrition facts labels[1]. It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integratio…

I'm still using last.fm and this is great! Thank you for this.

I'm working on a partition-oriented declarative data build system. The inspiration comes from working with systems like Airflow and AWS step functions, where data orchestration is described explicitly, and the dependency relationships between input and produced data partitions is complex. Put simply, writing orchestration code for this case sucks - the goal of the project is to enable whole data platforms to be made…

Wow, neat idea!

Is this going to be proprietary or OSS?

In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible.

Our first dinner was with 13 friends and has since grown into a group of just about 1,000 members. Last year we generated around $140k for local restaurants on off nights (dinners are on Tues and Wed when business is slow).

Now we are working on evolving into more of a lifestyle brand for people who love food. I'm currently working on our clothing line and new site, which we quietly launched a few days ago (there's still a few odds and ends to finish): https://www.deadchefssociety.com. Would love any feedback!

I'm working on a product to break down information siloes for private market investors. A lot of data for private equity, private credit, and venture capital firms lives in memos, deal books, conversation notes, emails, and chats. In some cases, attempts to organize that data in a more structured format (e.g. using the CRM) has resulted in data not getting recorded because of the friction of managing those types of systems.

So basically, I'm building a system where users can query all of that unstructured data and add more with a little less friction.
