PostHog
posthog.com ↗Open source product analytics: events, session replay, feature flags, A/B tests and surveys in one platform, with a real free tier.
PostHog is an open source product analytics platform. It covers event analytics, session replay, feature flags, A/B testing, surveys and error tracking in one product, on one data model. You can use their cloud or self host it, and the free tier covers around a million events a month before any payment is required.
The company launched in 2020 through Y Combinator and develops the whole platform in the open; the code is public on GitHub. One snippet feeds every tool, so a funnel, the replay of the sessions inside it and the flag that fixes the problem all live in the same place, joined on the same user.
What earned it a page here is the consolidation. Analytics, replays, flags and experiments usually mean three or four subscriptions, as many SDKs, and identity stitching between them. Replacing that stack with one product removes integration work that nobody bills for but everybody pays. Pricing is usage based, billing limits can be capped from the dashboard, and the free tier is large enough that a small product can run on it for a long time.

A pivot is often just the polite word we use with investors when the first company is dead and we have decided to build another one. And that is fine. Not because failure is noble, but because luck needs exposure: every market you enter, every product you ship and every channel you test is one more surface where something unexpected can land.

GoPerfect is an AI recruiting platform: you describe a role, it searches what it says are 800M+ profiles, scores each candidate from 1 to 5 with written reasons, and sends outreach by email, LinkedIn or SMS. Its plans are quoted on request, require a one-year commitment and are sized for two recruiters or more, so a founder filling one role should compare it with tools that publish their prices.
A self-hosted AI agent is an agent whose runtime you install on hardware you control. In most setups that covers only one of three layers: the runtime is yours, the model is still a cloud API, and the tools reach wherever you point them. Keeping the model local is a separate decision, and it costs memory, roughly 16 GB for the smallest capable models, plus some tool-calling reliability.

A cold email subject is the shortest true description of the one thing you are asking for. Not a hook, not a curiosity gap: a label. Its job is to filter, so the people who open are the people who could plausibly say yes, and everyone else deletes it from the list view without ever costing you anything.
The Tim Ferriss cold email template comes from his 2008 post on emailing busy people, and it is short by design: name something specific the person made, say who you are in one clause, prove you already did the work, ask one question they can answer in two sentences, and give them an easy out. The structure is public. The reason it works is not.
