I’m building a small web app where users post falsifiable conjectures and others respond with refutations, inspired by Karl Popper’s idea that knowledge grows through bold claims and critical testing.

How it works (MVP): • Users submit a conjecture (e.g. “UBI reduces non-violent crime”). • Each conjecture must include clear falsification criteria — what would prove it wrong. • Others post refutations: counterexamples, critiques, or better hypotheses. • Conjectures can be revised in response to valid criticism. • Future features: prediction markets, citation formats, version histories.

Why I’m experimenting with this: • Most online platforms reward persuasion, not falsifiability. • Forecasting platforms (like Metaculus or Manifold) focus on probabilities, not explanations. • This is meant to support idea evolution, not just outcome prediction.

Early stage: Built with Rails 8 and TailwindCSS. Still private, just validating whether this concept is useful or pointless.

Looking for feedback on: • Would you use something like this? Why or why not? • Is this meaningfully different from a smart blog comment section? • What is the smallest useful version of this? • What would make this fail completely?

If you’re interested in trying it or think it’s a terrible idea, I’d genuinely appreciate your thoughts.

I’m exploring venture capital funds that prioritise sustainability and profitability over continuous fundraising. Specifically, I’m interested in funds that provide an initial round of capital, aiming for the business to achieve profitability—an approach sometimes referred to as "seedstrapping". Ideally, these funds would be open to B2C investments in Europe.

I’ve identified a few such funds:

• OpenSky Ventures: An early-stage VC firm investing in category-disrupting companies, led by experienced entrepreneurs with a track record of successful exits.[0]

• D2 Fund: Focuses on funding capital-efficient B2B software businesses in the UK and Europe, emphasizing efficient entrepreneurship and mission-critical products.[1]

• TinySeed: A remote accelerator designed for early-stage SaaS companies, offering funding and mentorship to help founders grow sustainably without the pressure of traditional VC expectations.[2]

• Indie.vc: Known for its unconventional approach, funding startups with a focus on profitability and sustainability.[3]

For context, Anu Atluru’s essay, “One-Round Wonder”[4], explores the concept of startups achieving success with a single funding round.

Are there other funds or investment models that align with this “seedstrapping” philosophy? Insights or experiences with such funds would be greatly appreciated.
