Cyncz is one of 70 companies chosen by VentureBeat to launch at the DEMO Fall 2010 event taking place this week in Silicon Valley. After our selection, the companies pay a fee to present. Our coverage of them remains objective.

As a symptom of our increasingly connected lives, we’re building up contact data and address books that are spread across various services (email, social media) and devices. Trying to manage multiple sources of contact data manually is a lesson in frustration. That’s something the Germantown, Maryland-based Cyncz is aiming to fix with the contacts synchronization platform it’s unveiling today at the DEMO conference taking place in Silicon Valley.

Cyncz offers a subscription-based service that allows users to synchronize their contact data from multiple services and devices and eliminate duplicate entries for the same person. The platform supports contact data from email (Outlook, Gmail, and s on), mobile devices (iPhone, Android, BlackBerry, Windows Mobile), customer relationship management (CRM) tools like Salesforce, and social networks (Facebook, LinkedIn, and more).

Offering contact synchronization isn’t anything new, but Cyncz’s focus on cleaning up contact data certainly is. The company says it uses patent-pending data-deduplication algorithms to make sense of messy address books.

Using the service is simple: Users subscribe to Cyncz via its website, set up individual plug-ins for every service they want to pull contact data from, and then their combined contact data is automatically de-duplicated. Once the contacts are clean, they’re pushed back to the user’s address books. Users can also choose what contact data goes where — so your Facebook friends can remain separate from your work colleagues. The company says that any synchronization can be rolled back, so users don’t need to worry about losing their contact data if something goes wrong.

Cyncz counts services like Google Sync, Apple’s MobileMe, and Comcast’s Plaxo as competitors. But while those services focus on contact synchronization, Cyncz has the added ability of helping users make sense of their increasingly crushing amount of contact data.

The company was founded in 2009. Its two founders, Jaya Pandey and Neeraj Jaiman, are its only full-time employees. Additional engineering work came from a team of four contract workers in India. Thus far, it has raised $75,000 in a seed funding round from friends and family, and another $75,000 from the State of Maryland’s Technology Development Corporation.
