Sneos.com | Founder | REMOTE | I help compare outputs from multiple AI chatbots

At https://sneos.com, I've built a platform that allows users to write once and compare outputs from multiple AI models like ChatGPT, Claude, and Gemini side-by-side. This helps users understand the unique strengths and perspectives of different AI systems without the hassle of copying/pasting between services. Current Needs:

Growth Hacker (part-time/contract): Looking for a creative, data-driven growth specialist to help me scale the user base and optimize conversion from free to premium tiers. You should have experience growing B2C SaaS products and be comfortable implementing and analyzing marketing experiments quickly.

iOS/Android Developer (part-time/contract): While not an immediate priority, I'm interested in creating mobile versions of my web app. As the premium user base grows, I'd allocate more resources to mobile development. I'm open to sponsoring an open-source implementation initially, with potential for a more formal arrangement as user numbers increase.

Tech Stack:

Flexible (Objective C, Swift, Java, .NET, etc.)

What I Offer:

Flexible remote work Opportunity to shape a product in the rapidly evolving AI space Competitive compensation aligned with company growth

If you're excited about making AI tools more accessible and effective for everyday users, please reach out with your relevant experience and a brief note on why you're interested in working with Sneos.

Looking for my Shel Kaphan | Dirac | Lead Founding Engineer | 5% equity + £70k base (£100k base after series A) | London, Acton | in-person only

Dirac is building the next Walmart-sized retail company over 10+ years. We sell d2c and are doing £300k-£500k monthly sales (lots of toys and reasonably seasonal). I built most the initial systems which run the company’s backend (purchasing, databases, pipelines etc.) but we will need something (and someone!) better to reach £1bn+ sales over the next four years

We need to go from a bunch of bash scripts coordinated by systemd, adhoc estimators and pipelines to a more coherent machine for demand estimation, matching products, warehousing and purchasing.

You’ll be mostly writing code (django+postgre+a hetzner server) but also helping our two more junior devs.

The vision for the company is twofold: (1) find 1000s of suppliers and wholesalers worldwide and (2) to ingest all their pricing, logistics and then move stock to where prices and demand is highest.

Visa sponsorship possible.

Investors include will thorndike, charlie songhurst, patio11, backedvc and some others!

We’re creating robots that autonomously construct buildings. We design all of our hardware and software in-house in central Amsterdam, starting with autonomous bricklaying robots.
