Code Story: Insights from Startup Tech Leaders - S10 Bonus: Erik Braund, Katmai Tech

Erik Braund was born and raised in Alaska. Growing up, he played competitive hockey and built computers for his Dad's company and eventually others. He grew up with a gameboy, an electric guitar, and a love for Nirvana. He eventually upgraded his setup to a computer - which led him to setup a recording studio. He was internet obsessed from a young age, partially because it was the door to a bigger world outside of Alaska. He played in bands, started a recording studio, which eventually turned into a production company in NYC and LA, delivering AV projects for numerous clients.

Erik was running his production company when COVID hit. Given people weren't doing in person projects, he started consulting and opening up his mind on how to do these types of projects remotely. He started to see a new problem, where video conferencing was not solving high connection, collaborative work.

This is the creation story of Katmai.

Code Story: Insights from Startup Tech Leaders - S10 E30: Ravi Pratap Maddimsetty, Uniqode

Ravi Pratap Maddimsetty lives in Bangalore with his family. Early on, he joined startups where his friends worked, in order to get to know the landscape of how they functioned. He fell in love with the tech, team and early innings of building a business - so much so, that he eventually started his own. He has been an entrepreneur for 15 years - or in the woods, as he says. But outside of tech, he's married with 2 girls. He loves spending time with his family, playing tennis, being outdoors or skiing.

Ten years ago, Ravi was riding the wave of smartphones, tinkering with numerous technological solutions to connect users to their world via their smartphone. After moving through beacons, NFC, GPS and others - they started to think about how they could use the camera, which was on every device, to read QR codes.

This is the creation story of Uniqode.

  • This unlocks the same in aiohttp!

Brian #3: uv 0.6.15 supports pylock.toml

  • Discovered through Brett Cannon
  • So far, these projects support pylock.toml
    • pip
    • pip-audit
    • pdm
    • uv
  • With uv
    • To export a uv.lock to the pylock.toml format,
      • run: uv export -o pylock.toml
    • To generate a pylock.toml file from a set of requirements,
      • run: uv pip compile -o pylock.toml -r requirements.in

Talk Python To Me - #503: The PyArrow Revolution

Pandas is at a the core of virtually all data science done in Python, that is virtually all data science. Since it's beginning, Pandas has been based upon numpy. But changes are afoot to update those internals and you can now optionally use PyArrow. PyArrow comes with a ton of benefits including it's columnar format which makes answering analytical questions faster, support for a range of high performance file formats, inter-machine data streaming, faster file IO and more. Reuven Lerner is here to give us the low-down on the PyArrow revolution.

African Tech Roundup - Innovating Venture Building Support: David Ogundeko on Funema’s Vision for Backing African Ventures

Episode overview: In this conversation, David Ogundeko shares the journey of Funema, an impact-focused alternative investment firm operating for nine years across Nigeria, South Africa, and the US. He discusses his approach to venture building for early-stage founders, why Africa needs a unique investment approach, and how his firm addresses the "chicken and egg" challenge that idea-stage founders face: needing traction to raise funds while needing the right talent to gain that traction. Andile Masuku engages Ogundeko on the evolution of venture building in Africa, from being "mocked" five to six years ago to now becoming an essential element in the ecosystem. Throughout the conversation, Ogundeko makes a compelling case for why Africa's tech ecosystem requires patient capital with 15-25 year horizons rather than traditional 10-year VC fund lifecycles. Key topics: - The evolution of Funema's venture building model over nine years - Why service-based businesses can evolve into stronger tech companies - Misalignment between traditional VC timelines and African market realities - The importance of founder emotional connection to problems they're solving - How AI is democratising education and knowledge across the continent - Funema's ambitious plans to scale venture building across Africa Notable points: 1. Ogundeko developed his venture building thesis after working at Seedstars in 2016, flipping their model to focus on founders with their own ideas 2. Funema has a portfolio of 20+ companies built over nine years of operation The firm prefers working with founders who start with service models to develop deeper market understanding before scaling with technology 3. Traditional 10-year VC timelines are insufficient for African tech development, with Ogundeko advocating for 15-25 year investment horizons 4. Funema is planning to reach 1,000 founders over the next two years and train 100,000 venture builders over five years What makes Funema's approach distinctive is his patience and belief in deep market understanding: "We didn't exactly start out with a very sexy business model. But the learnings that we've been able to get from the market, which we've automated into a platform, is becoming a product that you can call a pure tech business."
