Today, we're proud to announce that we have closed a round of funding, raising $3.7M to expand our product development, sales, and marketing efforts. The round was led by Albert Wenger of Union Square Ventures, who will be joining our board of directors as president, bringing his experience from del.icio.us and founding 5 companies as an entrepreneur. We also welcome Dave McClure of Founders Fund, overseeing the seed-stage investment program. We extend a special thank you to family and friends for their support, and offer Twilio customers an exclusive $20 credit when upgrading or funding their account by New Years Day 2010 with the promo code "funding-yay".
