AI agents you can rely on

Every tool you use was built as an island, so you became the glue between them. You carry a name from Gmail into the CRM, a time from the CRM into Calendly, a note from Calendly into a doc. AI showed up and mostly became an eleventh window to paste into. Sauna is a hybrid of AI and software standing on one shared brain. It holds your context and hands you real software built on top of it. You talk to it like a chatbot and use what it builds like an app: software for the path you repeat, AI for the edge that never repeats. Keep it to yourself, or share the brain with your team. The clearest way to see it is a tool doing what its whole category cannot. An ordinary Calendly shows a stranger your free slots. Your Calendly writes the invite email itself, because it knows how the two of you know each other, and it offers a board member the slot over your gym block, because it knows which of your busy hours bend and for whom. Wordware is the team behind it, 15 people backed by Spark Capital, Felicis, and Y Combinator with a $30M seed, the largest in YC's history. We build from an office in the Presidio, fifty metres from Crissy Field beach, and we work absurdly hard because we can see and feel the outcome every day.

Founder/CEO
Cofounder and CEO at Wordware -- an IDE for Natural Language Programming and Agent Orchestration. Previously I cofounded and exited KRISTALIC, which tried to augment the human memory. Before that, I studied Deep Learning at Cambridge. The most interesting fact about me outside of work is that I travelled to 103 countries and was part of multiple high-altitude mountaineering expeditions and rescue operations in Kyrgyzstan and Nepal. I also do sailing, paragliding, kitesurfing and boxing.

Founder/CTO
Robert Chandler is a founder & CTO at Wordware. He started his career as an early engineer at a self-driving car startup, Five AI, which was acquired by Bosch. Here he lead the Offline Perception team which accelerated the dev-test cycle through automated ground truthing and was awarded 5+ patents in the process. He has been in the AI space for over a decade since studying Information Engineering at the University of Cambridge.
Company Launches
Wordware — Build your AI stack 20x faster
See original launch post

Wordware is an IDE that enables anyone to build complex AI Agents and applications. Domain experts and engineers can now iterate 20x faster with prebuilt tools, API deployment, tracing, and more.

Currently, prompting is mostly done by engineers inside the code base. This is just a coincidence, and it yields poor quality and a long iteration cycle due to communication overhead with domain experts.

Wordware is the go-to tool for these cross-functional teams. Our clients range from AI tinkerers developing their ideas to large companies using Wordware as their whole LLM backend.

It’s a tool (an IDE) that enables you to quickly build custom AI agents for specific use cases, like legal contract generation, marketing content automation, invoice analysis, candidate screening, generating PRDs, and many more. We call applications built on Wordware ‘WordApps’ because you can create them using natural language—in other words, using words (pun intended).

Our core belief is that the domain expert—not the engineer—knows what good LLM output looks like. For example, lawyers building legal SaaS need to be deeply involved in the process, and working directly in the codebase or going back and forth with engineers isn’t the way to go. Most of our clients are cross-functional teams, including less technical members, who need to collaborate with engineers on LLM applications, such as assessing prompt outputs, and care about the speed of iterations.

We are in production with 7 YC Companies and looking to give other early-stage companies with their AI Stack on fire unreasonable amounts of attention. Start for free or book a demo at www.wordware.ai.

I met Robert (my CTO) at the University of Cambridge. We have both worked with LLMs since BERT and created well-performing stacks before AI Ops was a term. We both have exits in the field.
