Adam Doppelt
About Adam Doppelt
Adam Doppelt is a Seattle-based software engineer and serial founder. Crunchbase lists a computer science degree from Brown University (1993 to 1997). He was an early employee at Jobster, and TechCrunch reported that he, Ethan Lowry and Patrick O'Donnell were all ex-Jobster staff when they started Urbanspoon.
Crunchbase counts six companies founded by Doppelt. The ones with public records are Strangeberry (2002 to 2003), Urbanspoon (2006 to 2010), Dwellable (2011 to 2015), Fresh Chalk (2019) and Blueprint AI (December 2022). It also lists Cubeduel, without dates. Urbanspoon, the restaurant recommendation service, was bought by IAC in 2009 according to TechCrunch. Dwellable, a vacation rental startup, was sold to HomeAway in 2015 according to GeekWire.
His current work is split across several companies. Crunchbase gives his primary role as Founder of Fresh Chalk, a service that surfaces home, health and beauty professionals recommended through a personal network. Its bio line names him as Founder of Blueprint AI. In 2025, GeekWire reported that he co-founded Alertmouse, an email alert service for tracking mentions of people and brands, with Rand Fishkin and Nathan Kriege.
Crunchbase shows 9 investments in 9 portfolio companies, with 0 lead investments and 4 exits (none by IPO). He is an individual angel investor, not a fund manager. No fund size or investing entity is public.
The records with dates are limited. CB Insights shows a May 2014 seed round in Smore of $1.7M, which included Greylock Partners, Kima Ventures and Founders' Co-op among other investors. Smore later exited, with CB Insights giving December 2022 as the date. EasyVC cites Crunchbase for an angel round in SparkToro dated June 7, 2018, which it describes as his most recent investment on record. Crunchbase lists VendorHawk, Smore and Shippable as his most notable exits.
Several co-investors in Smore were people he had worked with before, including Urbanspoon co-founders Ethan Lowry and Patrick O'Donnell. Many of his connections run through his founder network.
No public record shows Doppelt making angel investments in AI companies. His public AI activity is as a founder. Blueprint AI, which he started with Nathan Kriege, builds on large language models. Crunchbase describes it as a tool that uses existing systems to automate status reports and release notes. A ZenML case study describes its first product as a report generator that connects to Jira and GitHub and summarizes the activity it finds. Crunchbase lists the company as pre-seed, based in Redmond, Washington.
For founders, the more relevant signal is that he has built and shipped LLM-based software himself. Whether he would back an AI startup as an angel is not stated publicly.
Public sources are thin. EasyVC lists his stages as pre-seed and seed, and describes his focus as computer, internet, search engine and software markets. That is a summary drawn from his Crunchbase record, not a statement from Doppelt himself. He lives in Seattle, and the investments we could confirm are in software and internet companies.
We found no public statement from him about check size, ownership targets or what he looks for in a pitch. EasyVC mentions a $1.3 million figure for SparkToro, but that appears to be the size of the round and not his own check, so it should not be read as his typical investment. If you are considering a pitch, the evidence points to someone with a product and engineering background who has built consumer and software products from scratch.
