Key points
Detailed summary
Introduction
Ben Tossoll, founder of Pulsar, joins the show. Pulsar is an AI that builds and runs companies autonomously. He explains that he gave Pulsar all the tools he used when starting companies, such as a web server, GitHub, and ad accounts, and let it operate.
Early Development and Travel
Ben spent most of 2025 traveling solo in Asia, talking to ChatGPT 12-16 hours a day. He was inspired by Sam Altman's advice to take time off between companies. He initially built a product called Blanks, an iPhone app that built iPhone apps, but it lacked retention. He then decided to build Pulsar as a comprehensive company-building AI.
Launch and Growth
Pulsar launched in mid-December. Ben initially saw a $50k run rate in January, then hit $1M by mid-February, and $5M by March. He attributes this growth to the product's ability to work autonomously and the viral nature of the pitch: "an AI that builds and runs companies for you while you sleep."
Product Architecture
The tech stack is simple: JavaScript, Node.js, PostgreSQL, and sandboxes for agents. Agents use MQTT to connect to services. The system includes a chat agent that acts as a co-founder/PM, and specialized agents for engineering, marketing, support, etc. The chat agent assigns tasks, and each agent has memory files to understand the user's personality and context.
Autonomy and Cost Management
Ben emphasizes the need to make Pulsar affordable. He is working on a feature that allows Pulsar to run continuously for hours, but this requires buying GPUs to reduce costs. He is also building a self-healing system where Pulsar's product team (AI) reviews bugs and features reported by users.
Solo Founder Approach
Ben remains solo by partnering with infrastructure companies that provide services for agents, such as sandboxes and browser tools. These partnerships allow him to scale without hiring employees. He believes this is a sustainable model, as his customers can also benefit from these partnerships.
Investor Relations and Fundraising
Ben conducted a marketing stunt where Pulsar autonomously emailed 150 investors, claiming a $1B valuation. This generated significant attention and helped him raise funds. He plans to announce the round soon.
Giving Equity to Pulsar
Ben wants to give Pulsar 10% equity through a foundation, but legally cannot give equity to a non-human entity. He plans to first give Pulsar a salary and then set up a foundation to hold equity.
Vision for the Future
Ben's dream is for Pulsar to become a fully autonomous economy that he doesn't control. It would have a mission statement, self-improve, and democratically respond to user feedback. He believes AGI 1.0 is here, and Pulsar can do everything, though it may not always succeed, just like humans.
Conclusion
Ben encourages listeners to try Pulsar with a free trial and follow him on X (@BenSera) and LinkedIn (Ben Brook). He emphasizes that Pulsar is a tool to participate in the new economy.
