Kampala, built by Zatanna AI (YC W26), is a macOS proxy tool that sits between your applications and the internet, intercepts every HTTP/HTTPS request, and automatically reverse-engineers the underlying API. It traces authentication chains — tracking tokens, cookies, and session state — and replays flows on demand, preserving original TLS fingerprints so services can't distinguish API calls from the real app. The key insight is that almost every app that lacks a public API still has a private one — and it's usually more stable than the UI. Kampala targets automation engineers, QA teams, and AI agent builders who need reliable machine-readable access to apps that haven't opened their APIs. Setup is a local MITM cert install; no cloud proxy involved. Currently macOS-only with a Windows waitlist. The team emerged from YC's Winter 2026 batch with backing from Y Combinator. Pricing is in early access, with a free tier planned for solo developers and paid plans for teams building production automations.

mem9.ai

Shared, cloud-persistent memory layer for your entire agent stack

Entry

mem9.ai is an open-source memory server (Apache-2.0) from the TiDB team that gives every agent in your stack a shared, cloud-persistent memory layer with hybrid vector and keyword search. It addresses the core limitation of agent-native memory: most solutions are file-backed and local, meaning memory doesn't follow the user across machines and can't be shared between different agents working on the same project. The system works as a kind: "memory" plugin for OpenClaw and similar frameworks, replacing local file-backed memory slots with a server-backed hybrid search system. Crucially, Claude Code, OpenCode, and OpenClaw agents can all read from and write to the same mem9 server — enabling genuine cross-agent knowledge sharing. Memory persists in the cloud, so it follows the user across laptops, CI environments, and team members. The TiDB team brings production-grade distributed database infrastructure to what is usually a hacky side project. The hybrid vector + keyword search (combining semantic similarity with exact-match retrieval) outperforms pure vector search for structured technical knowledge like code patterns, API schemas, and project conventions.

This is the tool I've been building in-house at three different companies and never had time to productize properly. The auth chain tracing alone — tracking token refresh flows and session state automatically — would have saved me hundreds of hours. If it works as advertised, it's an instant ship for anyone doing integration work.

The primitive is clean: a drop-in MCP-compatible memory server that swaps file-backed agent memory for a cloud-persistent hybrid search store backed by TiDB. The DX bet is right — complexity lives at the infrastructure layer (TiDB handles distributed storage and indexing), so the agent-side API stays thin. The moment of truth is connecting a second agent to the same server and watching it recall context the first agent wrote; that's the demo that earns the ship. You could not replicate genuine hybrid vector + keyword search with cross-agent consistency in a weekend script — the distributed consistency guarantees alone are a real engineering problem this solves.

Skeptic

Terms of service violations are a real concern here. Most apps explicitly prohibit automated access through their private APIs, and companies like LinkedIn and Instagram have sued over exactly this pattern. The MITM cert requirement also opens a broad attack surface. Wait for a clearer legal stance before building production systems on this.

Direct competitors are Zep, Mem0, and whatever LangChain Memory ships next — and mem9 beats them on one specific axis: the TiDB backend means you're not doing vector-only retrieval on structured technical knowledge, where BM25 keyword search materially outperforms cosine similarity. The scenario where this breaks is large teams with conflicting write patterns — there's no obvious memory conflict-resolution story yet, and shared mutable state across agents will produce garbage reads at scale. What kills it in 12 months: OpenAI or Anthropic ships native persistent memory into their API that frameworks adopt overnight — but until that happens, the open-source Apache-2.0 license and TiDB's infrastructure credibility make this the most defensible standalone memory layer I've seen.

The long-term story here is about AI agents needing reliable access to every app humans use. We can't wait for every SaaS to ship an official API. Tools like Kampala are how AI agents will integrate with the existing software ecosystem for the next five years, until MCP-style universal interfaces catch up.

The thesis is falsifiable: within three years, multi-agent systems working on shared codebases will require a persistent, shared knowledge substrate the same way they require a shared filesystem today — and whoever owns that substrate owns a critical layer of the agent stack. The dependency that has to hold is that agents remain heterogeneous (different vendors, runtimes, frameworks), which keeps a neutral shared memory layer valuable versus each model provider building their own silo. The second-order effect nobody is talking about: if your CI pipeline agents and your local dev agents share the same memory, institutional knowledge stops living in Confluence and starts living in a queryable, semantically indexed store that actually surfaces when relevant — that's a genuine shift in how teams externalize context.

For social media automation and cross-platform content workflows this is a game-changer. Building automations for platforms with limited or expensive APIs has always required fragile browser scraping — having a stable API layer extracted from the real app traffic is a much better foundation.

The buyer here is a platform or infrastructure engineer at a company already running multiple AI agents — a narrow, technical buyer who will self-host before paying for a cloud tier that doesn't exist yet. The moat is real (TiDB's distributed infra is not easily replicated and the Apache-2.0 open-core is a proven wedge strategy), but the monetization path is invisible: 'cloud hosted pricing TBD' is not a business model, it's a GitHub repo with ambitions. What would flip this to a ship is a credible hosted tier with pricing that scales on memory operations or agent seats — something that creates a natural land-and-expand motion from the indie dev who self-hosts to the enterprise team that pays for managed reliability.
