Adapt.io vs Startup Tracker: Which One Do You Need in 2026?
You're comparing a phone book to a scout report. Adapt.io is a contact database. Startup Tracker is a startup search engine. They serve completely different moments in the prospecting workflow, and honestly, the fact that people compare them at all tells you how confusing the B2B tool market has gotten.
Here's what each tool actually does, where they overlap (barely), and whether you need both.
30-Second Verdict
Adapt.io if you already know which companies you're targeting and need emails and phone numbers to reach decision-makers. It's a contact database, plain and simple.
Startup Tracker if you're scouting newly launched or recently funded startups and don't need contact data yet. It's a discovery engine, not a prospecting tool.
What Is Adapt.io?
Adapt.io is a credit-based B2B contact database with 150M+ contacts across 30M companies. You know your ICP, you search by filters, you pull emails and phone numbers. That's the workflow.
The tool holds a 4.6/5 on G2 from 2,789 reviews, and the pattern across those reviews is clear: users love how fast they can pull contacts - 71 mentions praise ease of use - but consistently hit walls on credit limits, with 58 mentions tied to credit restrictions. G2 also reports a 4-month average implementation time and 16 months to see full ROI, which is worth factoring into your timeline if you're evaluating this seriously.
Pricing is transparent and credit-based, not per-seat. Free includes 25 Email Credits, 25 Enrichment Credits, and 25 contacts/day. Starter runs $49/mo ($490/yr) for 500 Email Credits and 500 Enrichment Credits, with 50 contacts/day. Basic hits $99/mo ($990/yr) and includes 1,000 Email Credits, 1,000 Enrichment Credits, 100 Phone Credits, CRM exports, and 100 contacts/day.
What Is Startup Tracker?
Startup Tracker positions itself as a "startup company search engine" that aggregates, crawls, and crowdsources startup profiles on demand. It's a discovery layer - you browse funded companies, not pull contact lists.
Here's the thing: Startup Tracker doesn't have a meaningful third-party review footprint. No G2 presence we could find, no Capterra ratings to reference. Pricing isn't published either, but comparable startup databases like Crunchbase Pro at $29/mo suggest a range of $29-$199/mo depending on features and seat count. If you're serious about startup discovery and want something battle-tested, Crunchbase is the more proven option in this category.
Adapt.io gives you contacts without discovery signals. Startup Tracker gives you discovery without contacts. Prospeo's 300M+ database with 30+ filters - including funding rounds, headcount growth, and buyer intent across 15,000 topics - does both in one search at 98% email accuracy.

When to Use Each Tool
Pick Adapt.io when:
- You've already built your target account list
- You need emails and phones under $100/mo
- Your workflow is simple: search, export, sequence
Pick Startup Tracker when:
- You're scouting newly launched startups or recent funding rounds
- You don't need contact data yet - just company intelligence
Let's be honest: most teams comparing these two tools actually need neither. They need a single platform that finds the funded startup AND the VP of Sales's email in one search, so they can book meetings instead of juggling tabs. We've seen this pattern dozens of times with outbound teams who duct-tape two or three tools together and wonder why their workflow feels broken.
A Better Option for Most Teams
Prospeo eliminates the two-tool problem entirely. The database covers 300M+ professional profiles with 30+ search filters - funding rounds, headcount growth, department size changes, and buyer intent across 15,000 topics via Bombora. Find the funded startup and pull verified contacts for its decision-makers in one search.
Email accuracy sits at 98% through a proprietary 5-step verification process. Mobile numbers cover 125M+ verified records globally, with data refreshing every 7 days versus the 6-week industry average. Pricing lands around $0.01 per email, with a free tier of 75 emails and 100 Chrome extension credits per month - no credit card, no contracts, no sales calls.
One of our users at Stack Optimize built from $0 to $1M ARR using this approach, maintaining 94%+ deliverability and sub-3% bounce rates across all their clients. That's what happens when you stop splitting your prospecting across disconnected tools.
Teams using disconnected tools burn hours tab-juggling and still end up with bad data. Prospeo refreshes every 7 days, verifies emails through a proprietary 5-step process, and costs roughly $0.01 per email - no contracts, no sales calls required.
Find the startup and its decision-maker's email in one workflow.
FAQ
Does Startup Tracker provide verified email addresses?
No. It's a company discovery engine, not a contact database. You'll need a separate tool - like Adapt.io, or Apollo - to get verified emails and direct dials for the startups you find.
How many contacts can you pull from Adapt.io per day?
25 on Free, 50 on Starter at $49/mo, and 100 on Basic at $99/mo. Credit limits are the single most common complaint across G2 reviews, so map your daily volume needs before committing to a plan.
Is there a free tool that combines startup tracking with contact data?
No single free tool does both well. Prospeo's free tier is the closest - 75 emails and 100 Chrome extension credits per month with 30+ filters covering funding rounds, headcount growth, and buyer intent - without paying for two separate platforms.
