Best Deal Flow Tools for Solo GPs
Direct answer
VC Deal Flow Signal, Crunchbase Pro, Folk / Attio, PitchBook compared for startup deal sourcing: signal type, lead time, coverage, and pricing. Use this side-by-side to pick the tool that matches your investment stage and sector.
Solo GPs run on tight budgets and tighter time. The right deal-flow stack maximises signal per dollar without locking the fund into multi-thousand-dollar annual contracts. The optimal 2026 stack combines a leading-signal layer, a funding-database layer, and a lightweight pipeline tracker, all with monthly billing and free tiers wherever possible.

Not investment advice. Engineering signals are one sourcing input among many, verify independently.
VC Deal Flow Signal, leading-signal layer
The free weekly Signal Report (5 startups every Monday) is enough to keep a solo GP looking at high-quality technical opportunities. The Dashboard at EUR 49/month adds 350+ ranked startups, sector and stage filters, and historical lead-time audit. Engineering acceleration is causally upstream of fundraise announcements, for a solo GP whose edge depends on getting in before the round is competitive, this is the highest-value monthly subscription.
Crunchbase free + Pro, funding-data layer
Crunchbase free is sufficient for verifying funding history, founder backgrounds, and past investors on companies you discover via signals. Crunchbase Pro at $49/month adds advanced search, alerts, and unlimited profile views, useful once your sourcing volume crosses 10+ companies per week. Skip PitchBook and CB Insights at the solo-GP scale; the price-to-utility ratio is wrong.
Relationship layer, lightweight options
Affinity is enterprise-priced and overkill for a solo GP. Notion, Airtable, or even a structured Google Sheet with a calendar reminder column works fine for under-50 active relationships. Once you cross 100+ active relationships, consider Folk ($25/month) or Attio (free tier with paid upgrades), both are mid-priced relationship CRMs that approximate Affinity at solo-GP scale.
Network amplifiers
AngelList free tier for syndicate participation, Twitter/X for inbound founder discovery (run a list of operators in your sectors), and a Telegram channel or Slack workspace for peer co-investors. None of these cost money; the cost is consistent attention. Most solo GPs underestimate how much weekly Twitter/X discipline matters.

Verdict
The optimal solo-GP stack in 2026 is VC Deal Flow Signal Dashboard (EUR 49/mo) + Crunchbase free or Pro + a lightweight CRM (Folk, Attio, or a structured spreadsheet). Total cost: EUR 49 to ~$80/month depending on volume. Skip enterprise tools, the marginal value does not justify the cost at solo-GP scale.

Frequently Asked Questions
What is the cheapest deal flow stack for a solo GP?▾
VC Deal Flow Signal weekly free tier + Crunchbase free + a structured spreadsheet. Total cost: $0/month. Sufficient for sourcing 5+ technical startups per week. Upgrade to the EUR 49/mo Dashboard once you want sector and stage filters.
Should a solo GP buy PitchBook?▾
No. PitchBook is built for institutional research teams. The same budget covers ~170 months of VC Deal Flow Signal Dashboard. Solo GPs source signal-first, not research-first, the database tier is overkill.
Is Affinity worth it for a solo GP?▾
Generally no. Affinity is enterprise per-seat pricing built for multi-partner firms. At solo-GP scale, Folk ($25/mo), Attio (free tier), or a structured Notion / Airtable setup covers the same workflow.
