Technical cofounder- So Calif

Love the focus on building, not just coding. Wishing you the best in finding the right co-founder—happy to connect!

We might be an unconventional fit here. I run Unilo Studio, a small product studio. We are not looking for a cofounder seat, but founders in your spot (multiple businesses, strong distribution, product that needs building) sometimes prefer a long term build partner over giving up equity: we design, build, and ship in four weeks on a fixed price, and stay on after launch. Three products we built are live right now, you can find them on our profile. If the cofounder route is the goal, good luck either way. If a build partner sounds interesting, happy to talk.

Hey Brian — not pitching equity-only cofounder, but if you want to move faster on a specific AI/SaaS idea first, I do paid vibe-coding MVP builds (auth + core workflow + AI features in ~7–14 days) and custom LoRA fine-tunes on your docs.

Happy to do a scoped trial project so you can test working rhythm before any longer partnership. DM me with the one-liner + timeline if useful.

One thing worth adding to the location filter: a technical cofounder's working rhythm matters more than their postcode, and you only learn rhythm by working together. A scoped trial project of a couple of weeks beats months of coffees, whoever you find. Biased here because I'm building CoBuildr around exactly that (post the role, trial before commitment, opens early August), but the two-week test is free advice.

Hi Brian, I’m Sabbir, a software engineer and startup founder. Your background in lead generation and customer acquisition is exactly the business-side strength I look for in a cofounder. I can build full-stack SaaS, AI agents, automation workflows, and MVP-to-production systems. I’d like to discuss your first product idea, target customers, validation, and how we could test a trial sprint together.

Hi Brian, if you’re still looking, I’d love to discuss my experience and how interesting this sounds.
Tried to reach you but I couldn’t find a way to contact you.
Hoping to hear from you

Hey Brian, it's Sami, founding engineer experience building AI-powered SaaS products partnering with founders to bring ideas to market. Your post really resonated with me, and I'd love to connect and explore.

Hey Brian, your profile is the exact complement to mine.
I'm Hamza, founder of Zaaric, an AI dev agency where I've shipped production systems for US and EU clients: a HIPAA-compliant healthcare platform, an enterprise e-commerce system processing massive customer bases, and Sehat, an AI health memory platform built on Next.js, Supabase, and OpenAI Agents SDK, and many other production grade software for clients.
What I bring beyond code: I think in products and distribution, not just features. I've done zero-to-one multiple times and I understand why most SaaS products die before they find customers. I have good leadership exposure as well which is validated by international level leadership programs including Qimam Fellowship.
Would love to explore more about your idea, current position and vision about it.
