Overview

GoScale was a cloud infrastructure startup founded in 2011 by Colin Hayhurst and James Cunningham, originally under the name StackBlaze before rebranding prior to its Y Combinator Summer 2012 acceptance. The company built a platform for elastically scaling virtual machines — described officially as "Dynamical Scaling Virtual Machines as a Service" and informally as "Heroku for PHP" — targeting developers who needed automatic, millisecond-speed cloud scaling without the operational overhead of managing infrastructure manually.^[1][2]

GoScale failed because it occupied a product layer that the major cloud platforms were actively absorbing. AWS Auto Scaling, Heroku's expanding language support, and Google App Engine were simultaneously commoditizing the exact capability GoScale was trying to sell, leaving a two-person, effectively unfunded team with no defensible position and no clear path to a seed round.

The company ceased trading in 2014, roughly two years after completing YC, with no acquisition and no public post-mortem.^[3][4] Both founders landed well afterward — Hayhurst became CEO of Mojeek, an independent privacy-focused search engine, while Cunningham joined a series of high-growth UK fintechs before founding a second startup.^[5][6]

Founding Story

Colin Hayhurst came to GoScale with a credible track record. In 2005, his prior startup Century Dynamics — a computational physics software company — was acquired by NASDAQ-listed ANSYS, giving him a successful exit before most founders in the YC S12 cohort had shipped a first product.^[7] That background in technical infrastructure software shaped his instinct for the cloud scaling problem: the pain of managing server capacity manually was real, and the tooling available to most developers in 2011 was still primitive.

James Cunningham joined as CTO and brought a different kind of credential — youth. He would later describe himself as "one of the youngest founders to go through Y Combinator" in the Summer 2012 batch.^[8] The combination of a serial entrepreneur with an exit and a technically precocious CTO was a classic YC founding profile.

The company was incorporated in 2011 under the name StackBlaze before rebranding to GoScale.^[9] No public record explains what prompted the name change or whether it reflected a product pivot. The Mojeek blog later confirmed the evolution, referring to the company as "Y Combinator summer 2012 company StackBlaze/GoScale" in a 2020 post.^[10]

The founders' pre-YC hustle is best illustrated by a side project they built for their own application: iPG, an interactive simulator that let founders practice answering Y Combinator interview questions in the style of Paul Graham. The tool was covered by TechCrunch on April 27, 2012, just weeks before the S12 batch began.^[11] The iPG simulator described GoScale's product as "cloud computing that scales in milliseconds" — a phrase that captures both the genuine technical ambition and the marketing challenge the company would never fully resolve.^[12]

The team operated with a geographic split: London-based by origin, with a Sunnyvale presence during the YC program itself.^[13] This UK-founder-goes-to-YC pattern was common in the cohort, but it likely complicated post-Demo Day network building in the Bay Area investor community — a disadvantage that would matter when the team needed to raise a seed round.
