DevTools of the Week

StackGen Turns Cloud Nightmares into Dev Wins
StackGen, founded in 2023 by Sachin Aggarwal and Asif Awan in San Ramon, California, grew from Aggarwal’s cloud security startup Accurics which sold to Tenable.
The company’s Generative Infrastructure platform has shone brightly in its first year, delivering innovative ideas and bold breakthroughs. In 2024, they snagged $12.3M from Thomvest Ventures, WestWave Capital, and others, doubled their crew, and hit Google Cloud Marketplace, winning over heavyweights like the NBA, SAP, Autodesk, and InMobi. InMobi’s CTO Mohit Saxena raved:
“StackGen helps us create consistent and standardized cloud-agnostic IaC with built-in security.”
According to their Stacked Up: IaC Maturity Report, 97% of IaC users face big difficulties, 93% want urgent innovation; StackGen answers by generating secure cloud setups from anywhere, speeding multi-cloud adoption.
This March, their “Cloud to Code” feature launched via a podcast with experts Dharani Vijayakumar and Arunav Sarkar, showing off how it slashes DevOps grunt work. Co-founder Arshad Sayyad also highlighted a new partner program with integrators and cloud providers, set to streamline migrations and modernization next.
Safe to say, StackGen’s killing it, helping enterprises ditch cloud lock-in and move faster, safer. They’ve earned our spotlight this week for turning chaos into clarity—swing by stackgen.com to see why!
