Key Features

Derrick App offers 28+ modular data enrichment workflows that you activate according to your needs:

• LinkedIn Profile Scraper: complete enrichment of LinkedIn profiles with emails, phones, and company information

Unlike Seamless.AI which imposes a proprietary platform, Derrick App integrates directly into your existing spreadsheets via a Google Workspace add-on.

Transparent Pricing

Plan	Credits/month	Price	Best For

Common Seamless.AI Limitations

Before choosing your alternative, understand why many teams seek to replace Seamless.AI:

1. Opaque Credit System

Users report unpredictable credit consumption, with actual costs far exceeding initial projections. One contact can consume 1 or multiple credits depending on data found.

2. Non-Transparent Pricing

The Basic price ($147/month) only appears in the interface after registration. Pro and Enterprise plans require sales contact, making comparison difficult.

3. Variable Data Quality

Email bounce rate reported between 15-30% according to users, with phone numbers “hit or miss”. The announced 1.3 billion profiles database is more marketing than usable reality.

4. Rigid Annual Contracts

Paid plans generally impose 12-month commitment, with early cancellation penalties.

5. Criticized Customer Support

TrustRadius and Reddit report frustrations regarding support responsiveness and billing issue resolution.

6. Limited Features

Seamless.AI focuses on prospecting, lacking modern features like:

• Advanced AI for scoring and qualification
• Background enrichment
• Sophisticated automated workflows
• Predictive analytics

Recommended alternative: Derrick App solves these problems with unlimited rollover credits, transparent pricing from $9, background processing, and 28+ flexible workflows.

---

Start by testing for free: all mentioned tools offer free trials or freemium plans. Derrick App offers 200 renewable free monthly credits, perfect for evaluating the solution on your real use cases before any commitment.
