# VentureDex Turns Startup Discovery Into an Evidence File > Explore VentureDex for curated startup profiles, product evidence, funding sources, investor context, launch videos, and original startup research. - Published: 2026-06-16 - Updated: 2026-09-14 - Author: Gene Dai - Canonical: [https://digidai.github.io/2026/06/16/venturedex-startup-discovery-evidence-file/](https://digidai.github.io/2026/06/16/venturedex-startup-discovery-evidence-file/) - Topics: Startups, Venture Capital, Product Research, Market Research --- VentureDex's September 8, 2026 research snapshot records 304 startup profiles and 1,000 linked research sources. Open the [directory](https://venturedex.co/directory) and those records become a practical starting point: companies organized by product, funding stage, and region, with a route from each profile to the material behind it. [VentureDex](https://venturedex.co/) is a curated startup discovery and research publication. It brings company profiles, funding news, investor pages, product launches, topic maps, and editorial research into one place. Founders can explore a market; investors can build an initial research list; product teams can find companies working on a specific problem. Open a company profile and you can read what the product does, who it is for, and which sources support the description. That first file helps you decide whether to spend more time on the company. The [Startup Evidence Index](https://venturedex.co/research) makes the publication's scope visible: | Published inventory | September 8, 2026 snapshot | | --------------------------- | -------------------------: | | Startup profiles | 304 | | Linked research sources | 1,000 | | Distinct source domains | 444 | | Product-evidence statements | 803 | | Investor records | 254 | These figures describe VentureDex's own published inventory, not the entire startup market. Its approach is selective: build a useful, inspectable record for the companies it covers. ## Start with the company you want to find A founder researching a new product category does not necessarily need the newest company on the homepage. They may need an infrastructure startup at a particular stage, or a product serving a market outside the United States. Those are different searches. The [VentureDex directory](https://venturedex.co/directory) supports filters for product type, funding stage, and region, together with sorting controls. Each company card provides a short product description and basic company context. You can narrow the list before opening individual records. You can search without knowing a company name. Begin with a product question: which startups are working on inference infrastructure, developer workflows, payment operations, or energy systems? Use the filters to reduce the list, then read the descriptions for the task each company handles. A narrow first pass is easier to use. An engineering team looking for help with deployment review can set aside products focused on code generation, even if both appear under developer tools. A founder studying payments can distinguish an orchestration product from a company selling banking infrastructure. The short description helps make those early cuts; the profile supplies the detail. You can also browse without a fixed shortlist. VentureDex covers software, AI infrastructure, financial technology, healthcare, climate products, and physical systems. A product manager studying software may find an operating model worth examining in electricity or logistics, outside their usual reading list. The [About page](https://venturedex.co/about) identifies founders, investors, operators, and builders as its audience. The shared need is straightforward: understand what a company offers and why it might deserve more attention. VentureDex gives each reader several ways into the same research. For an initial visit, choose one category and open three profiles. Compare the intended customer and the work each product performs. A small set is enough to see whether your original question needs to become more specific. Keep the result in your own research note: the company, the task it handles, a VentureDex profile link, and one reason to follow up. A company can belong in that note because it fits your problem, or because it helps explain a market. This gives the browsing session an output you can return to, without needing to turn every discovery into a purchasing decision. ## Inside a VentureDex company profile Each company page keeps the product description close to its supporting material and editorial assessment. You can read the summary first, then follow the parts that matter to your research. Consider the [VentureDex profile of empirik](https://venturedex.co/startups/empirik). It describes a product for examining infrastructure dependencies before a change reaches production. The page connects that description to [empirik's own product material](https://empirik.ai/), identifies the intended users, and records the date the research was checked. The product capability remains a company claim unless independently tested. The profile also raises a concrete question: how useful is the dependency model if it falls behind the systems it describes? That question gives a reader something to investigate when they continue to the source material. It is more actionable than a generic claim that a startup is promising. The [Wafer profile](https://venturedex.co/startups/wafer) follows a different product problem. VentureDex describes inference optimization across models, serving engines, kernels, and hardware. Readers can compare [Wafer's product description](https://www.wafer.ai/) with [Wing Venture Capital's investment rationale](https://www.wing.vc/content/investing-in-wafer); both are interested-party sources, so neither is treated as an independent performance benchmark. The market discussion asks whether a separate optimization business can keep an advantage as infrastructure providers add similar capabilities. The [Light profile](https://venturedex.co/startups/light) shows the same research format outside conventional software tooling. It explains a service for businesses offering branded electricity plans and points readers to [Light's own product site](https://www.poweredbylight.com/). The editorial discussion points to the operational work behind enrollment, billing, and electricity supply; it does not independently validate regulatory coverage or service performance. Across these examples, VentureDex gives readers a consistent way to examine very different companies. The funding source, product material, and open questions remain available beside the summary. A reusable reading note can be short: | Question | What to take from the VentureDex profile | | ------------------------- | ---------------------------------------------------------------------------------- | | Who uses this? | The stated customer and the job the product handles | | What can I inspect? | Product pages, documentation, demonstrations, or repositories linked in the record | | Why follow this company? | The editorial explanation of its product or market bet | | What needs another check? | The stated risk, missing evidence, or unresolved product question | | When was this reviewed? | The research-review date, kept separate from the funding date | This is a suggested way to use the publication, not a claim that VentureDex provides private diligence or hands-on testing of every product. Its [editorial policy](https://venturedex.co/editorial-policy) describes a public-source approach. VentureDex and this site share the same author, so this walkthrough is a first-party disclosure, not an independent review. A linked company or investor statement remains an interested-party statement; the source trail lets you inspect it. ## Browse a market, then compare a workflow Collections and topics answer different browsing needs. [VentureDex Collections](https://venturedex.co/collections) groups companies under recognizable themes, including AI agents, developer tools, fintech, open source, climate, and physical AI. It is a convenient entry point when you know the area but have not yet decided what to compare. [Topic maps](https://venturedex.co/topics) add research context. They connect relevant profiles with funding information and related weekly coverage. Their organizing questions are closer to the work a product does: agentic software, engineering infrastructure, legal workflows, financial operations, or healthcare. The distinction matters when a category contains products that are not substitutes. Two companies may both sell to developers while addressing different stages of engineering work. Reading them side by side is still useful, but only after identifying what each one actually handles. The [developer tools topic](https://venturedex.co/topics/developer-tools-startups) supplies a comparison table with product descriptions, latest recorded funding, location, and source-review dates. Its coverage section explains the scope of the list. The full set of profiles and links to relevant weekly research sit on the same page. Read the product column before the funding column. It tells you whether the company belongs in the comparison at all. Location and recorded financing add context; the review date tells you when the public material was examined. A recent review is not a record of a customer deployment or hands-on product test. For example, start with the engineering task you want to understand. If the problem is checking a proposed change, keep products aimed at running or reviewing that change. If the problem is production performance, move toward observability or infrastructure tooling. Then open the corresponding profiles and inspect their source trails. This method works for market research as well as product evaluation. A founder can compare how companies describe their customer, which integrations appear in their documentation, and where their public descriptions become vague. The result should be a more precise research question, not an assumed ranking. For a recurring research meeting, bookmark the topic and save the profiles you discussed in your own notes. On the next visit, compare the current source material with the question you recorded. The topic page keeps the surrounding companies and editorial coverage within reach. ## Follow funding back to the company Funding announcements can be useful prompts for research. Their value improves when the company and product context stay close to the number. The [VentureDex funding news page](https://venturedex.co/news) links recorded rounds to company profiles and attributed sources. It gives readers a way to notice financing activity and move directly into the corresponding research. A reader interested in a round can check the recorded stage and date, then follow the funding source. That sequence is worth preserving. A round date describes a financing event. A profile-review date describes research work. Neither establishes how well a product performs today. Use the funding page to ask where you want to spend your attention. A newly recorded round might justify reopening a company you have already studied, or exploring a product category you have missed. The company profile can then help you decide which question to follow. [Investor pages](https://venturedex.co/investors) provide another route through the publication. They connect an investor to companies and financing activity tracked by VentureDex. If a firm's name appears in a profile, you can use that connection to explore other covered companies. Follow a company to its investor context and look at the products in the linked records. You may find a neighboring market or a company you would not have searched for directly. Tracked portfolio counts cover VentureDex's inventory, not a firm's complete investment history. They help you navigate covered companies; they should not be used to estimate a firm's market share or investment performance. For a recurring market review, keep a short list of profiles and note what made each one relevant. When you return through the funding or investor pages, you have a reason to open the record and a question to check against the new material. ## Watch the product, then read the research Some product ideas are easier to understand through a demonstration. [VentureDex Launches](https://venturedex.co/launches) collects product launch videos and walkthroughs on individual pages, with the original video and post. The channel includes search and category controls. It gives readers a more visual route into product discovery alongside the written company directory. A demonstration can answer a simple question that a company description leaves open: what does the user actually do? Look for the input, the action on screen, and the result. Those details can help you decide whether to investigate the product further. Launch coverage has a different scope from researched company profiles. A video entry does not by itself establish a funding event, customer adoption, or an endorsement. Treat it as a product signal and use the linked material to continue the investigation. For a more edited view, [VentureDex Weekly](https://venturedex.co/weekly) groups selected companies around a shared product development. Each issue connects its argument to company records and sources, giving readers a reason to consider those companies together. The September 7, 2026 issue, [Products Are Taking Control of the Next Step](https://venturedex.co/weekly/13), examines six companies through the actions their products take. Rather than covering one software category, the issue moves across administrative work, infrastructure, energy, and physical products. Its common question concerns what happens after a system produces information. Readers can compare where each product takes action and what remains subject to review. The issue supplies the editorial connection; the linked profiles provide more detail. VentureDex also publishes focused research briefs. Its September 8 comparison, [Coding-agent verification: runtime, replay, and measurement](https://venturedex.co/research/coding-agent-verification-stack), examines three different kinds of evidence around software changes. It distinguishes a runnable environment, a frontend replay, and an engineering metric, then proposes questions for evaluating them. The brief turns existing profiles into a specific comparison. Readers can inspect the argument, open its source ledger, or take its evaluation questions into their own research. The page labels the work as editorial analysis rather than a product benchmark. ## Take the source trail into your own tools VentureDex supports readers who work outside the browser as well. Its [AI access guide](https://venturedex.co/llms.txt) points to a compact startup index, individual company resources, and a recent-changes feed. The guide explains how to find a company and retrieve its JSON or Markdown representation while keeping the canonical profile link and source references. That is helpful for a research workflow in which a person or assistant collects several records before comparing them. The smaller resources let the workflow retrieve a specific company instead of loading the whole publication. The source mappings help distinguish a product statement from the editorial assessment around it. The [structured research index](https://venturedex.co/ai-index.json) and [full text corpus](https://venturedex.co/llms-full.txt) are also available for work that needs broader context. They provide alternative ways to inspect VentureDex's material; they do not turn public research into independently verified company data. A sensible research note keeps the company name, canonical profile URL, review date, and supporting source beside any extracted claim. If an assistant summarizes several profiles, ask it to retain those references and identify missing information. That makes the summary easier to check later. The same discipline helps human readers. Copying a product description without its source or date makes it harder to know what needs updating. Preserving those details lets another reader retrace the research instead of accepting the summary on trust. The [research index](https://venturedex.co/research) states that access for search, retrieval, and citation does not grant an open-data license or permission for model training. Check that boundary before reusing the material beyond a research and citation workflow. These resources make VentureDex usable in more than one reading environment. You can browse visually, read the publication in a feed reader, or retrieve a company record for a source-linked note. ## Choose where to begin The best starting page depends on what brought you to VentureDex. | Your task | Start here | Useful next step | | ------------------------------------ | ------------------------------------------------ | ------------------------------------------------------ | | Find startups in a product category | [Directory](https://venturedex.co/directory) | Filter the list and open a few relevant profiles | | Understand how a market is organized | [Topics](https://venturedex.co/topics) | Compare use cases and follow the linked research | | Browse a broader area | [Collections](https://venturedex.co/collections) | Explore company cards within an editorial theme | | Follow financing activity | [Funding news](https://venturedex.co/news) | Read the company record and original funding source | | Explore investor connections | [Investors](https://venturedex.co/investors) | Inspect activity within VentureDex's covered companies | | See a product in use | [Launches](https://venturedex.co/launches) | Watch the demonstration and open the original post | | Read an edited selection | [Weekly research](https://venturedex.co/weekly) | Follow the issue's argument into individual profiles | A product team preparing for a vendor conversation can arrive with a narrower question after reading a profile and its sources. A founder exploring the same page might instead save it for a market review. The research supports both uses without requiring a buying decision. You do not need to review the entire directory to get value from it. Pick one question, read a few profiles, and record what still needs checking. If the question changes, use a topic page or investor link to explore the next set of companies. To keep following the publication, [subscribe to VentureDex](https://venturedex.co/subscribe). The subscription page offers choices for company additions and weekly research. The [VentureDex RSS feed](https://venturedex.co/feed.xml) provides another way to follow the work in a feed reader. Start with the [directory](https://venturedex.co/directory), open a company you have not studied, and follow one source link. That is enough to turn a new name into the beginning of a research file. --- _Published June 16, 2026.
