Legal Documents Solution for Emerging Startup

We basically came to them with nothing but a clear vision for what we wanted our MVP to do, and they’ve over-delivered to give us a full MVP. Even when we’ve ended up adding on some really out-of-scope requirements at the last minute, they’ve still delivered within our original timeframe and budget. This project has a legal focus, so it requires a lot of learning to know what to build, and they’ve gone above and beyond to understand everything.

5.0 Mar 10, 2021

By and large, InApp’s ability to understand and absorb our needs is hugely important. We’re pretty good at specifying those things, but that specification is kind of dry and doesn’t capture the essence of our UX. There’s a qualitative aspect to it that can’t be quantified. If we communicate concerns or priorities, InApp will work with us to make those things happen according to best practices.

ERP for Promotional Product Firm

4.5 Mar 9, 2021

The project managers are very capable. They know the project and our requirements. InApp clearly explains to us what’s possible, what’s tough, and what’s not realistic. We have very good discussions. I’m impressed with how the developers are able to catch all the business needs and understand our business processes.

Development for Contractor Management Software Company

5.0 Aug 12, 2020

They delivered the project that we asked them for exactly to our specifications. We’ve been very satisfied with the quality of the platform and the seamless service that it has allowed us to provide to our customers, so I really think they did an excellent job. Their project management is just as excellent as their development skill. They have consistently gone above and beyond to make sure that they understand all of our requirements and that our teams are on the same page about the overall goals of the project.

Why Trust Clutch

At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.

Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.

Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.

We evaluate service providers using a structured methodology that combines:

In-depth client interviews and ratings
Comprehensive project details
Market presence
Portfolio examples and industry recognition

This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.

Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.

We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.

Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.
