Twenty Ideas Reviews & Testimonials

Startups Software Development Review from Justin Collins
Our first engagement with Twenty Ideas was accurately scoped and allocated from day one, and that was impressive. Being on time and budget while exceeding expectations seems impossible for many vendors, but with Twenty Ideas, there were zero issues. They anticipated our needs and presented clear options when necessary.

Mobile App Development Review from Rachel Efron
The most impressive thing was the collaboration we established. I had been creating this app by myself for so long, and all of a sudden, I had a whole team of thought partners. Twenty Ideas really got in there with me, learned what I was trying to make, and collaborated with me on it. It was an extremely rewarding experience, and we're thrilled with the app!
Jana DiSanti's Review Sourced from Google
I started working with Twenty Ideas in a part-time consulting capacity, but I became so taken with the team’s passion, mission, and supportive culture, that I ended up applying for a full-time position. I’ve been with the team for three and a half years now, and it’s given opened doors to expand my skill set; work with smart, kind, and dedicated people, every day; and work with clients who truly care about making a positive impact, to create life-changing solutions together. It’s a great place to work!

Watson Creative Reviews & Testimonials
Janet Sandra's Review Sourced from Google
Over the last three years, I have collaborated on over eleven projects with Watson Creative team. They are a pleasure to deal with and consistently produce outcomes that go above and above! For your upcoming project, I heartily recommend them.
Holt Group Inc.'s Review Sourced from Google
Watson has been a key strategic partner for us on the creative and brand side since the beginning. We've worked with various members across the team and every member of their staff brings excellence and authentic passion to what they do. They have consistently delivered an end product that excites our customers, adding special creative touches along the way so that the results really sing. The way they're able to translate our vision and mission into deliverables across each project has been a weight off our shoulders. Not every creative agency is able to understand the nuances of our industry and we've been so impressed with the time team Watson has taken to really get to know our industry in homebuilding. We've worked with Watson on deliverables such as high level creative direction, but also getting into the nitty gritty of developing content around our warranty program. This was a huge task and they matched us with exactly the right team members to bring it to life who truly cared about getting it right. They're great friends as much as they are our business partners. We highly recommend partnering with Watson Creative.
S Nash's Review Sourced from Google
When we engaged Watson to help us rebrand, we knew it was going to be a challenging process. We had a long-standing reputation as a respected law firm in Portland, but we wanted our brand to reflect our unique culture and the innovative approach we bring to our clients. Watson's team was thorough and thoughtful throughout the entire process, from primary research interviews with our team to the final custom, hand-drawn identity system. The end result was a brand that not only represents who we are as a firm but also sets us apart from our competitors. We continue to receive compliments on our branding years later, and we credit Watson for helping us achieve that success.

5 steps to a blockchain proof of concept (POC) is very nice guide to start blockchain project POC, it gives clear direction about the POC and explains in depth what is required at each step to have successful POC.
