Constructive

Your digital construction kit for secure, modular Postgres. Build production apps that last.

[Dan Lynch @danlynch]

Code generation isn't the moat. Engineering is.

Last week I sat on a panel at the SVB Experience Center with Sanjeev Dhanda (@GoogleDeepMind) and @abhiaiyer (@mastra) on the move from vibe coding to agentic engineering

We're at capacity for the tonights session! Couldn't be more stoked to chat about building systems that agents and humans can converge on to build trusted code with Sanjeev Dhanda (@GoogleDeepMind) and @abhiaiyer (@mastra)!

Thanks @Kristopherfloyd (Frontier Syndicate) and Joanna Zanghi (@SiliconVlyBank), and Acasia for co-hosting with @constructive_io 🚀

Using @PlanetScale's own benchmark data. Removing the volatile and non-optimized polices, pure RLS vs. no RLS (I'm including original data for comparison)

This is what performance looks like when security is done right.

[Dan Lynch @danlynch]

Interesting take on RLS from @PlanetScale — but the “per-row overhead” they highlight isn’t a limitation of RLS, it’s a consequence of how the policy is written

a thread on their take and benchmark 🧵

[Dan Lynch @danlynch]

This is exactly why, and completely validates everything we do at @constructive_io because RLS is complex and must be managed or you'll make every mistake that @PlanetScale is assuming here. We solve all of these issues, and then some 🚀

happy to share @constructive_io just made the front page of TechDay ⚡️

We open sourced agentic-db
→ Postgres as the memory layer for AI agents
→ no more markdown hacks
→ no more stuffing context into prompts

Agents are probabilistic. Your data shouldn’t be!

[Dan Lynch @danlynch]

AI can write the code. Engineers have to make it secure and correct

Speaking on a panel representing @constructive_io with AI leaders from @GoogleDeepMind (Sanjeev Dhanda), @abhiaiyer (CTO, @mastra) at the SVB Experience Center on moving from vibe coding → agentic engineering ⚡️

Yesterday at the @postgresconf I spoke about secure-by-default, modular Postgres ⚡️

As agents start generating applications, the database becomes the trust layer.

Security can’t be a follow-up step anymore—it has to be the starting point. This is what we’re building at @constructive_io

Hanging at @postgresconf with @Kristopherfloyd 🚀

[Dan Lynch @danlynch]

Had the pleasure of sitting down Greg Kemnitz and Curt Kolovson about the origin of Postgres, two of the original programmers from when it started 40 years ago! What a journey it's been and such a successful project. More importantly, I’m grateful to call them good friends.

Just landed - stoked for @postgresconf 🐘

Give your agent a brain 🧠

[Dan Lynch @danlynch]

We just open-sourced agentic-db — a Postgres knowledge base and personal CRM you can install in one command.

pgpm install agentic-db

Vector search, full-text search, fuzzy matching, spatial queries, and auto-embedding triggers. All inside Postgres.

Hosted @constructive_io Build Night #1 at @AngelList in San Francisco at @founders_cafe

Room full of builders actually shipping. Feels like the days when I first came to SF circa 2010. The energy is real! If you're building something cool, you should come to our next one.

Appreciate @Kristopherfloyd and @irinson for co-hosting this amazing community event!

More to come :)

Build Night #1 at @AngelList’s @founders_cafe

Hosted by @constructive_io @Kristopherfloyd (Frontier Syndicate) and @irinson

Room full of AI + frontier builders actually shipping. 🧵

[Dan Lynch @danlynch]

We're over capacity for @constructive_io's Build Night at @AngelList HQ!!

100+ approved builders working across the agentic stack — agent security, orchestration, infrastructure, trust, voice, fintech agents, and autonomous systems that touch real users and real money.

I tried Modular Postgres (@constructive_io) recently and it changed how I think about database structure

Instead of piling everything into migrations:
→ you define modules
→ set dependencies
→ deploy in order

Wrote a practical intro on what I learned:

[Dan Lynch @danlynch]

I asked @DevinAI — hey, how would you pitch @constructive_io ?

[Dan Lynch @danlynch]

Join us for @constructive_io Build Night at @AngelList HQ & @founders_cafe to talk about the stack after @openclaw

This is the first of a new builders series, get in early!

​There will be lobster rolls. Space is limited 🦞
