Best Investor & LP Databases in 2025

Fundraising in 2025 is about timing more than reach. Dollars are flowing again—concentrated in AI and a few crowded verticals—while many funds still take longer to close. That mismatch creates narrow windows when allocators move and inboxes open. The edge isn’t a bigger list; it’s mandate-timed signals, verified routes to decision-makers, and private-wealth depth that turns research into meetings.

Two facts set the backdrop. First, U.S. startup funding surged 75.6% in H1 2025 to $162.8B, driven by AI, while VC fundraising fell to $26.6B across 238 funds and time-to-close stretched—a classic “exits up, vehicles slow” regime. Second, structural frictions are shifting: from April 1, 2025, companies on Japan’s Prime Market must disclose financials and “timely disclosure” items in English (with a formal grace mechanism for early filers). That permanently lowers information friction for foreign capital and anyone courting it.

There’s also a practical bridge between the private and public sides of your thesis: U.S. equity REITs ended June/July near a ~19–20% median discount to NAV, an example of where listed proxies can carry conviction while private allocations season. Meanwhile, data-center electricity consumption is set to more than double by 2030, with AI as the main driver—so location and grid access now shape where AI-adjacent capital clusters.

Altss is built for exactly this market. It’s an all-in-one investor intelligence layer—OSINT + allocator social listening + entity resolution + deliverability guardrails—so you can spot intent in public signals and reach the right person in the right week.

How to pick a database that actually moves your raise

Mandate intelligence. If a platform can’t show who allocates to what (and when intent changes via events, filings, or people moves), it’s a directory, not a fundraising tool.
Deliverability. Routes must be verified and de-duplicated; otherwise you’re measuring bounces.
Private-wealth depth. Family offices, RIAs, advisor teams, and endowments/foundations need structure and recency, not just labels.
Relationship graph. See who backs whom and where warm paths exist.
Workflow fit. Saved searches, alerts, and notes that match your IC cadence.

Altss was designed around those constraints. We listen for allocator signals across filings, news, conference rosters, and personnel updates, resolve them to clean entities, and route you to the principal—so your message lands when intent is visible.

The platform landscape—by what each one is built to do

• Altss — Action layer for fundraisers. OSINT-verified LP/GP graph across family offices, RIAs, endowments/foundations; allocator social listening (mandates, events, people moves); verified decision-maker routes; relationship paths; saved searches and alerts tied to public signals.
• PitchBook — Context heavyweight. Deals, funds, companies, co-invest histories, and benchmarking—excellent for IC memos and diligence.
• Preqin — Institutional allocator research. Alternatives benchmarks, fundraising, investor and manager views—used when your LP mix is pensions/endowments/sovereigns or consultant-led.
• FINTRX — Private-wealth map. Family offices, RIAs, broker-dealers, advisor teams; strong when your motion runs through advisor networks.
• Dakota Marketplace — Institutional relationships + programming. Useful for distribution teams selling into traditional allocators.
• With Intelligence — Curated signal layer. Analyst/journalist-researched allocator intentions and upcoming mandates—great for context and timing, not a replacement for outreach.
• Dealroom / Crunchbase — Discovery layers. EU-centric predictive discovery (Dealroom Signal) and global investor/company prospecting (Crunchbase); feed your action layer with better names.
• S&P Capital IQ Pro / LSEG Workspace — Capital-markets context. Comps, ownership, transactions; essential for banks/AMs; complement private-wealth and mandate-timed outreach.

In practice, the 2025 stack that wins is Context (one heavyweight) + Signals (curated intelligence) + Conversion (Altss).

Ratings by buyer type (what to use—and why)

Startups (venture & strategic capital)

Run Altss as your action layer from day one. Our allocator social listening surfaces who cares about your theme this week—from family offices and RIAs to corporates building strategic programs—by watching public signals (event agendas, filings, principal moves, portfolio actions) and resolving them to the right decision-maker. You get principal-level routes, warm paths, and saved searches that trigger follow-ups the moment new signals hit, so you’re emailing because something changed, not because your calendar told you to. In a year when U.S. startup funding surged while VC fund closes lagged, timing—not volume—is the edge.

Family businesses (expansion, minority recaps, co-invest)

Make Altss your direct path to owners and CIOs. We map family offices and private-wealth teams inside one entity-resolved graph and listen for mandate language, board/principal changes, and conference footprints. That context lets you approach the right principal with a clear “why now”—for example, a new thematic focus noted in coverage or a partner’s public remark at an industry event—then route to a verified inbox. Family offices remain committed to private markets over long horizons; the difference is reaching them when intent is visible.

Emerging managers (Fund I–III)

Altss compresses the “signal → meeting” loop that gets first closes over the line. You’ll work from an OSINT-verified list of decision-makers, relationship paths to warm intros, and alerts tied to fresh public signals. Keep your IC workstreams, but let Altss drive outreach cadence: short sequences, follow-ups only on new signals, and weekly list refreshes so you never push a cold message. In 2025, startup deal flow rebounded while fundraises stretched out; managers who act when allocators show intent in public book the meetings.

Asset managers (multi-channel distribution)

When mandates tilt to private wealth, Altss is your engine. Use allocator social listening to segment by theme, check size, domicile, and timing; use our entity graph to see who backs whom and where warm paths exist; use deliverability guardrails to land in the principal’s inbox, not a catch-all. If your thesis has listed proxies (e.g., real assets or data-center adjacencies), marry Altss’s mandate signals to public-market entry points to meet allocators with a tradable expression while private diligence seasons.

Investment banks (private placements & strategic raises)

Altss gives banking teams direct family-office/RIA access inside live processes. Identify which principals are active in your theme, how they invest (direct, co-invest, fund), who can introduce you, and the verified route to reach them. Our OSINT core watches for event appearances, new mandate language, and principal moves globally; outreach triggers when those signals fire, which is precisely when private-wealth allocations are most responsive. In a market defined by short liquidity windows and AI-skewed flows, speed to the right principal is the differentiator.

Why Altss is the “all-for-one” solution

OSINT—without the noise. We ingest filings, policy changes, board/principal moves, conference rosters, allocator press, and portfolio actions—then resolve them to LP/GP entities. Signals become alerts, not trivia. Example: Japan’s Prime-Market English-disclosure requirement (effective April 1, 2025) materially reduces friction for foreign teams; we track changes like that and push them into your searches.

Allocator social listening. Most listening tools follow companies. We follow allocators: mandate language surfacing in coverage, strategy notes, principals added to agendas, moves across boards or ICs. Combined with entity resolution, you get a why now and a who exactly—the two ingredients generic databases miss.

Private-wealth depth that works for ICs. Family offices, RIAs, advisor teams, and endowments/foundations sit in one graph—linked to the managers they back. You can map who backs whom, trace warm paths, and prioritize principals who can say “yes.” If you already use a private-wealth mapper for breadth, Altss layers in timing, signals, relationships, and deliverability so lists turn into meetings.

Deliverability that compounds. Decision-maker routing, de-dupe, and bounce controls are first-class citizens. Fewer, better sequences—tied to fresh signals—protect domain health and accelerate meetings.

Stack-friendly. Keep one context heavyweight. Keep one curated signal feed if you want. Altss sits beneath as the action layer: saved searches on your live themes, alerts when signals change, and verified routes to the decision-maker for the next 14 days.

The 14-day “signal → meeting” loop (use this verbatim)

Days 1–2 — Turn on saved searches for live themes (e.g., AI × energy systems, climate infra, health data). Import current lists; resolve duplicates; promote principal-level routes.
Days 3–5 — Annotate each target with a signal reason (event, filing, role move). Draft a 4–5 sentence opener anchored to that reason.
Days 6–7 — Launch two micro-sequences (max 3 touches). Pause any contact that hard-bounces; Altss auto-routes to an alternate if available.
Days 8–14 — Trigger follow-ups only when new public signals hit (mandate language in press, event appearance, board change). Book calls; roll what worked into your IC pack.

Where the macro meets the stack

• Funding up, fundraising slow: H1’25 startups raised $162.8B while VC funds raised $26.6B; exits and later-stage allocations can clear quickly, but new vehicles grind. Tools that surface intent in public (and route to principals) win.
• Policy lowers frictions: Japan’s English-disclosure rule is a permanent reduction in information friction for the Prime Market; your stack should notice and react.
• Public mispricings help private theses: ~19–20% REIT NAV discounts show where listed proxies can carry thesis risk while private diligence completes.
• Power is the AI bottleneck: Data-center electricity demand set to double by 2030; siting and grid access now influence where AI-adjacent investments cluster—and where the right LPs are watching.

Bottom line

2025 rewards precision over volume. The winning stack blends context, signals, and conversion—and gets you on the calendar fast. Altss is the all-for-one layer that makes that loop work across startups, family businesses, emerging managers, asset managers, and banks:

• OSINT + allocator social listening focused on mandates, events, and people moves.
• Entity-resolved LP/GP graph that shows who backs whom and where warm paths exist.
• Deliverability safeguards that route to decision-makers and protect domain health.
• Saved searches and alerts that trigger follow-ups when signals change—not when a reminder fires.

Bring a live theme. We’ll show you the mandates and routes that matter—and help you convert signal → meeting → allocation while the window is open.
