About GuessWorks.

Entrepreneurship is a lot of GuessWork.

But the best entrepreneurs aren’t just the ones with the best guesses, they’re the ones who know how to work through them.

We don’t believe there is a “formula” for successful innovation. It still relies on a lot of individual smarts, and even more so on timing.

But, we do believe that there are skills, approaches, experts and tools, which that can help any founder test their ideas faster; lowering the risk of building the wrong product, or investing too long and too much into a flawed business model.

We help early-stage founders or entrepreneurs apply these skills to their ideas in search of problem market and then product-market fit. We get their ideas to market faster, cheaper and with a higher chance of success.

A little Background on Our Own Founder…

GuessWorks was founded in 2021 by Hattie Willis, a Venture Builder, Startup Coach and Trainer, Speaker and Faciliator.

Hattie first fell into the startup scene while still at university when she was offered an unlimited supply of brownies and free cocktails to join a mobile-gifting platform called GiftCannon. The autonomy and empowerment she was given to try things, fail and learn was infectious, and she has been in love with the power of entrepreneurship ever since.

After GiftCannon, Hattie worked in four more startups, all in different industries, and with different business models, including an entrepreneurship education startup called Founder Centric. Here she learned from a group of incredible and inspiring founders turned trainers, and caught the bug to start practicing and sharing them herself.

Taking this into corporate innovation, Hattie became a Lean Startup Coach, and then Head of Training at Rainmaking, where she designed and delivered innovation programs and workshops with companies including Jaguar Landrover, Lloyds Banking Group, DHL, Airbus and Experian to name a few.

In her spare time, she kept testing ways to take Lean Startup skills into the Social Impact Space, whether working on Impact Accelerator Programs, as a coach, or 1:1 with charities and social enterprises.

Wanting to share these startup skills even further, she also created Rainmaking’s new digital learning business line. Convinced this was the future of entrepreneurship education (luckily still before Covid accelerated the change) Hattie managed to sell and then build the first platform; including designing the curriculum, writing and directing the training videos, and delivering modules too.

Once the product was live and tested across Rainmaking’s Corporate Accelerators globally, another opportunity beckoned: Rainmaking Venture Studio. Here, Hattie was responsible for testing, and pitching new ventures for co-investment with corporate partners She lead venture concepts including a direct-to-consumer luxury play, a Mental Health platform, and Financial Services AI.

But her passion for entrepreneurship education wasn’t done just yet. So she launched GuessWorks to help upskill and inspire fellow founders, while she continues to test new ideas, particularly around the mental health space, and around challenges such as how to help underrepresented founders get equal access to funding and support.

Hattie is also a regular speaker and panellist, including at The Lean Startup Conference, Tech BBQ, Corporate Innovators, and World Creativity Day.
