Things built by Chris Seline

Here are a few of the things I have built over the years.

Darkblock - a decentralized encryption protocol that enables creators to monetize all types of content using NFTS. I authored the protocol, then as CEO raised $1.85m with my co-founders.

GRX - A data fusion product that pulled from closed and open data sources to create an investigative tool that leveraged graph analysis, geospatial analytics, and search. Built at PlanetRisk where I managed the engineering team on this product. GRX was then sold to Everbridge, and I took over as product owner and ran the entire team, then we sold it again to our main client.

Personifind - A social media influencer search engine that indexed over 400 million social media profiles, and analyzed 10's of billions of social connections, to create a way to search for influencers on any topic. I was loan developer. Leveraged NLP, graph analysis, and all sorts of custom algorithms. Built on Elastic.

Twicsy - a Twitter picture search engine that indexed over 10 billion Twitter pictures and had over 400 million visits. It also had a footprint in Google of over 2 billion pages, driving 9 million unique visitors per month at its peach. I built and ran Twicsy entirely solo. I took it from idea to launch in 8 days. I launched it by sending on email to Techcrunch, and they wrote about it twice in the few days after launch.

And referenced in dozens of books.

Someone even wrote a song that talked about Twicsy but I can't find it anymore.

Dumbfind - a general web search engine that used a topical PageRank algorithm to enable vertical search engines to be created at query time. Because I like competing with Google for some strange reason. I built the beta for Dumbfind entirely solo and ran it out of my house with 30 home-built servers crawling the web through 7 DSL lines. The initial index was 400 million pages, which was a lot back in 2004. I was known as the dumbfounder, and that moniker has stuck to this day.

Not much to be found on Dumbfind anymore, here is one article still accessible:

Searchles - Social search engine built on Dumbfind technology. Connect to friends and search the content they are saving. Think del.icio.us but with search and graph analysis. Seemed like a good idea at the time. There were a few articles written about it on Techcrunch:

2wrongs.com - Before Google was a household name, but after Silicon Valley knew it was going to be a beast, I created 2wrongs.com. It was a search engine that crawled the web for user bookmarks (people used to post these online!) and constructed a high quality search index. My co-founder and I raised $2.6m in VC. Google was a bit more successful. I built most of the foundational tech, then the engineering side as CTO.
