Bitesize | Technical cofounder | San Francisco | Remote

We are looking for a technical cofounder who is extremely passionate about messaging and enabling companies to have personal relationships with customers at scale.

We are a small scrappy early stage startup with live paying customers and passion for helping companies succeed and treat their customers with the most personalized experience.

The product we are working on right now:

Zero second response: With the rise of instacart and amazon, people are becoming more impatient and expect things to happen right away. Nothing can be further from that than a company demo sign up form. The norm is to get "We'll get back to you in 24 hours!" when in reality people are ready to buy when they are filling out the lead form. Bitesize's zero second response enables customers to get a personalized text message from the company right away and start talking to a sales rep. We think customers shouldn't wait 1 day or even for 4 hours, they should hear back right away!

Text Drip Campaign: Most people are familiar with scheduled email drip campaigns... it sends emails that are scheduled to go out in the next 30 days for example. But email inboxes are becoming overwhelming, it's hard to grab someone's attention or be personal. Well, how about a text message drip campaign? We allow companies to trigger a text message drip campaign based on their website, Salesforce, Hubspot, or other triggers. Then the companies can send personalized text messages that actually sound like someone is personally texting you and respond.

Why aren't these products available in the market already? It's two things - we have an extremely unique point of view when it comes to texting. We believe every text message should sound like it came from a friend or a neighbor. We don't like marketing texts. Two, we have a secret weapon when it comes to navigating tricky TCPA regulations, so we can help protect our customers.

Are you ready for a ride of your lifetime? You would be a great fit if:

You are great at working independently and get hands dirty writing code You work on a quick sprint basis and narrow down features to take no more than 2 weeks You have great verbal and written communication skills, with experience putting tech specs together and like to define the features before jumping on it You have experience managing scaled platforms (with 1,000+ concurrent users) You take great responsibility for code on production server and make sure testing environment is highly similar to produciton environment You take great effort to try to see it from the customer's perspective and build product form the customer's perspective.
