AI makes it possible to build an MVP in a weekend, but it doesn’t guarantee anyone will buy it. After joining AltaLab, an accelerator founded by an investor with 10+ unicorns in his portfolio, I learned practical frameworks for evaluating startup ideas. Here’s how to assess founder–problem fit, validate demand through customer interviews, and distinguish genuine willingness to pay from polite enthusiasm—before writing a single line of code.

A QA engineer at inDrive shares three levels of AI-assisted QA: investigating bugs in code, prioritizing issues using production data, and shipping fixes through code review. Real cases include 1.86 million misleading server errors and a production fix that reduced duplicate-key errors by 30%. AI speeds up the work, but engineers remain responsible for verifying results.

Security analyst Tushar Karumudi is applying advertising technology data to threat intelligence investigations through paytrace, an open-source project that follows shared advertising identifiers across websites. When a suspicious or anonymous domain reveals little about its operator, connected sites may contain useful ownership clues in current or archived pages. By combining advertising IDs with resources such as the Wayback Machine and OpenCorporates, investigators can develop leads about the people or businesses behind websites. The findings still require verification, but the approach gives analysts another way to investigate suspicious domains.

1Claw founder Kevin Jones explains how HSM-backed vaults, spend limits and revocation keep AI agents from holding the master key to wallets and APIs.

Kevin Jones, Founder and CEO of 1Claw, says an AI agent should get permission to perform a specific action, never the master key to the credentials behind it. 1Claw sits between the agent and the resource, verifying the agent's identity, applying security policies and routing signing requests through a protected mechanism, with HSM-backed vaults, per-agent spending limits and an enclave proxy that screens model traffic for prompt injection. It signs transactions across more than 109 EVM chains as well as Bitcoin, Solana, XRP, Cardano and Tron. It has announced integrations with Bankr, Google Cloud, Circle, Tenderly, Coder and XRPL. The conversation cites CrowdStrike's fastest recorded breakout of 27 seconds and the $1.5 billion Bybit theft as reasons security cannot depend on humans reacting in time. Revocation cuts an agent off from protected credentials, but accountability for what the agent already did stays with the company that deployed it.

A five-person equity research firm with no biologists flew to Anthropic's New York office, ran an unreleased Claude research model against five scorpion neurotoxins, and generated 318,484 designs in 64 hours. Labs tested 211; 17 bound. None bound more than one toxin, and nothing was tested for neutralization. Design took days. Everything after it took two months.
