The investor behind a startup tells you a lot about the company — its stage, growth expectations, sector focus, and how much runway it has to spend. This hub brings together Growth List’s complete investor intelligence collection, organized around two practical uses: finding companies to target by who backed them, and understanding the investor landscape that shapes startup buying behavior.

Target by Investor or Accelerator
VC portfolio companies and accelerator alumni are among the highest-quality prospect pools available. They’ve been vetted by professional investors, have validated business models, and — critically — have capital to spend. Filtering your outreach by investor or accelerator is one of the most efficient ways to reach companies that match a specific profile: stage, sector, growth trajectory, and buying readiness.
1,076+ Andreessen Horowitz Portfolio Companies 2026
A complete database of a16z portfolio companies — one of the most valuable prospect lists in B2B sales. Andreessen Horowitz backs companies across AI, FinTech, crypto, healthcare, and enterprise software, typically at Series A and beyond. Their portfolio companies are well-funded, fast-growing, and led by founders with high expectations for the tools and services they buy. Includes company details, funding stage, sector, and contact intelligence for outreach.
Why this matters for sales: a16z portfolio companies tend to be in aggressive growth mode — hiring fast, building infrastructure, and evaluating vendors at scale. A single VC relationship gives you a coherent list of companies with shared characteristics, making personalization far easier than cold prospecting from scratch.
5,000+ YC Startups: Y Combinator Companies 2026
Y Combinator is the world’s most prolific startup accelerator — its alumni network includes Airbnb, Stripe, Dropbox, and thousands of earlier-stage companies actively building and spending. This database covers 5,000+ YC-backed companies across every batch and sector, with funding details, company stage, and contact data. YC companies are disproportionately B2B software focused, making them high-intent targets for tools, agencies, and services selling into the startup ecosystem.
Why this matters for sales: YC-backed founders are predisposed to buy from other startups and tech-forward vendors. They move fast, make decisions quickly, and have strong networks — a good experience often leads to referrals within the YC community.
Key difference between these two:
| a16z Portfolio | YC Startups | |
|---|---|---|
| Backer type | Venture capital firm | Accelerator program |
| Typical stage | Series A–D | Pre-seed through Series B |
| Database size | 1,076+ | 5,000+ |
| Sector focus | AI, FinTech, crypto, enterprise | Broad, skews B2B SaaS |
| Best for | Targeting later-stage, well-funded companies | Broader early-stage outreach |
Understand the Investor Landscape
Knowing which VCs are active, what sectors they back, and how their portfolio companies behave helps sales teams identify patterns — and time outreach more precisely. A company that just closed a round from a top-tier VC is in a fundamentally different position than one that raised 18 months ago.
The 500 Most Active Tech Investors in the US
A comprehensive reference list of the 500 most active US tech VC investors, with investment counts and exit data. Useful for understanding the depth of the venture landscape beyond the household names — many of the most active investors operate quietly, backing companies that don’t make TechCrunch but are growing fast and buying aggressively. Covers firms across all stages from pre-seed through late-stage growth.
Top 25 AI VC Investors

988 Crypto & Blockchain Investors
A comprehensive list of 988 venture capital firms and investors active in crypto, blockchain, and Web3. While crypto funding cycles have been volatile, the sector remains active — and crypto-backed startups have distinct characteristics that make them interesting outreach targets: high technical sophistication, founder-led purchasing, and significant capital deployed from recent raises.
Sequoia Portfolio Companies
Sequoia Capital is one of the most storied names in venture — its portfolio spans Apple, Google, and thousands of current-generation startups across enterprise software, AI, and consumer tech. This guide covers Sequoia’s active portfolio, investment focus, and what it means to target a Sequoia-backed company, which typically signals strong product-market fit, high growth expectations, and serious capital backing.
Why Investor-Backed Companies Are the Best Sales Targets
Not all startups are equal as sales prospects. Investor-backed companies — particularly those that have recently raised — have a specific profile that makes them consistently higher-converting targets than general startup outreach:
They have budget. A startup that just closed a funding round has capital allocated and a mandate to deploy it. Unlike bootstrapped companies where every spend is scrutinized, funded startups are expected to invest in the tools and services that help them scale.
They have urgency. Investor expectations create timelines. A Series A company is expected to hit specific milestones within 18-24 months. That urgency translates directly into faster vendor decisions and less friction in the sales process.
They’ve been validated. Professional investors do significant due diligence before writing a check. A company backed by a16z, Sequoia, or YC has been vetted in ways that most prospects haven’t — you’re reaching companies with real products, real customers, and real growth trajectories.
The 0-90 day window is critical. The period immediately after a funding announcement is consistently the highest-response window for cold outreach. Budgets are being allocated, teams are being built, and new vendors are being evaluated. Our guide on selling to funded startups covers exactly how to time and frame outreach in this window.

FAQs
What is the best way to find companies backed by a specific VC?
Growth List maintains portfolio databases for major investors including Andreessen Horowitz and Y Combinator, with verified contact data and funding details for each portfolio company. For broader VC portfolio research, Crunchbase and PitchBook maintain comprehensive investor-to-portfolio mappings, though without the verified contact data needed for direct outreach. Our funded startup database lets you filter by funding stage and sector regardless of specific investor.
Why target startups by their investor rather than by industry or location?
Investor filtering is one of the most powerful ways to create a coherent, personalized prospect list. Companies backed by the same VC share characteristics — typical stage, growth expectations, sector focus, and often a similar buyer profile. This makes investor-filtered outreach easier to personalize at scale than broad industry or geographic lists. It also signals buying intent: a company that just raised from a top-tier VC is almost certainly in active vendor evaluation mode.
What’s the difference between a VC portfolio and an accelerator batch?
A VC portfolio consists of companies a firm has invested in directly, typically at Series A and beyond, with significant capital and board involvement. An accelerator batch (like Y Combinator) involves smaller initial investments across a cohort of early-stage companies, with the primary value being the program, network, and demo day exposure. For sales targeting, VC portfolio companies tend to be later-stage with more budget; accelerator alumni skew earlier-stage but are often more accessible and faster-moving. Both are high-quality prospect pools for different reasons — see our a16z portfolio and YC startups guides for the specifics.
How do I know when a startup has recently raised funding?
Growth List’s funded startup database is updated weekly with new funding announcements, making it the fastest way to identify companies in the 0-90 day post-funding window. TechCrunch, Crunchbase, and Axios Pro Rata also track funding rounds as they’re announced. Our guide on sales trigger events covers how to monitor funding announcements and build outreach sequences around them.
Which investors back the most startups in AI right now?
The most active AI investors currently include Andreessen Horowitz (dedicated AI fund), Sequoia, Khosla Ventures, General Catalyst, and Coatue at the growth stage, with seed-focused firms like Pioneer Fund and Conviction active at earlier stages. Our AI VC guide covers the top 25 active AI investors in detail. For the companies they’ve backed, our AI startups database provides verified contact data and funding details.
