Most B2B software feature requests end up in the same place: a backlog that quietly grows until everyone involved has moved on to other jobs. Vendo, part of Y Combinator's Summer 2026 batch, thinks it has found a shortcut around that stalemate. Just let the customer build it themselves.
The company's open-source tool dropped on GitHub in the summer of 2026 with a straightforward pitch. Install it in your product, and your users can describe what they need in plain English. Vendo generates the interface, wires it to your existing API, and runs the whole thing in a locked-down sandbox so nobody accidentally breaks production. No developer time required, at least in theory.
It's the kind of idea that sounds either brilliant or reckless depending on who's been burned by custom integrations before. Vendo is betting the former. The tool has attracted a modest following on GitHub and a handful of early supporters, though the company hasn't disclosed how many customers are actually running it in live environments or what kind of revenue it's generating.
Founder Yousef Helal, a Berkeley EECS grad who also holds an MS from Stanford and later worked on FPGA infrastructure at Apple, makes the case that most customization requests aren't actually that complex. A sales team wants a dashboard that pulls data in a specific way. Operations needs an automation that fires on a schedule. Engineering wants an internal tool to talk to Slack or Salesforce without waiting for the product team to prioritize it.
"A chatbot talks about your product; an embedded agent operates it," the company wrote on its site, drawing a line between conversational interfaces and something more functional. Vendo positions itself closer to the latter, though the boundaries get blurry when you're generating code on the fly based on natural language prompts.
The technical execution leans heavily on sandboxing. Everything runs in QuickJS, a lightweight JavaScript engine with no direct access to the DOM or network calls. The host product's permissions, approval workflows, and audit logs all stay intact. Vendo extracts API endpoints from OpenAPI specs or Next.js server actions, then orchestrates them through a proxy that the vendor controls. If a user tries to build something that touches sensitive data or triggers a billing action, the vendor decides whether it needs a human to sign off first.
That control layer matters more than it might seem. B2B software vendors have spent years hardening their permission systems, and the last thing they want is a third-party tool poking holes in that architecture. Vendo's claim is that your source code never gets touched, which should appeal to security teams even if it raises questions about how seamless the integration really is in practice.
The company supports a long list of external integrations, from the usual suspects like Gmail and Stripe to more niche tools. It also exposes the same capabilities to external assistants through the Model Context Protocol, so someone using Claude or ChatGPT could theoretically orchestrate actions inside a SaaS product without switching contexts. Whether that feels like a feature or a risk probably depends on how much you trust LLMs with your workflows.
Vendo isn't alone in this space. Rough and CustomAdapt are both chasing similar ideas, offering agent-driven feature builders for B2B platforms. Prismatic, an embedded iPaaS, launched an AI copilot for workflow building in March 2026. Jotform rolled out an AI app builder around the same time. And Emergent, a consumer-focused platform, pulled in $23 million from Lightspeed in September 2025, according to TechCrunch. The broader category of generative app tools is crowded enough that differentiation starts to hinge on execution details that only become clear after you've deployed the thing for a few months.
Pricing follows a usage model: you pay for compute time, sandbox execution, storage, and automations. Annual plans start at $490 for the Pro tier and climb to $4,990 for Teams. Customers can bring their own API keys and infrastructure to shave costs down, though that adds complexity on the vendor side. The company notes that a SOC 2 Type II audit is underway, which suggests it's serious about enterprise sales even if it hasn't named any reference customers yet.
The tool launched on Product Hunt in mid-August and landed in fourth place that day. It drew a respectable number of followers on the platform, though those early metrics don't always translate into sustained traction. Open source can be a double-edged sword in SaaS—you get visibility and community contributions, but monetization becomes trickier when anyone can self-host.
Vendo's core insight is that most feature requests aren't really feature requests. They're workflow problems dressed up as product gaps. If the customer has the tools to solve it themselves without waiting for a sprint planning meeting, maybe the backlog stops being a bottleneck. Whether that vision scales beyond early adopters will depend on how many product teams are willing to hand over that much creative control to their users, and how many users actually want to write English prompts instead of filing tickets and moving on.
For now, the company remains small—two people as of late summer, backed by Y Combinator partner Ankit Gupta and Founders, Inc. The code is live, the integrations are expanding, and the bet is on the table. The question is whether the SaaS industry is ready to let customers stop asking for features and start building them instead.
