TikTok's #DIY hashtag has 116B+ views. The r/DIY subreddit is closing in on 20M members. Searches for "DIY near me" are enjoying all-time highs.
Consumers and investors alike are rolling up their sleeves and diving into DIY, with a new focus on digital platforms.
The big picture: Traditionally brick-and-mortar heavy, recent raises and sales data point to DIY's pivot to e-commerce.

Over the last year, digital DIY platforms have raised serious dough: UK startup Lick raised $28M, and France's ManoMano raised a cool $355M.
Stateside, Home Depot's e-commerce sales more than doubled over the last year to reach ~$20B. Competitor Lowe's rose at a similar rate to hit ~$9B. But there is still significant room for growth: These dollar amounts only represent ~14% and ~10% of revenue, respectively.
There is plenty of market white space, as well as valuable lessons from new players that can be applied to the ~$400B US industry.
The digital-only model: Newcomers ManoMano (EU) and Lick (UK) are solely e-commerce players, and both of these (very new) platforms are using models not yet fully leveraged in the US.
The platform grew sales by 100% last year, with 70% growth in unique site visitors to reach 50M per month.
A similar model could be applied to the US market. Founders could also leverage existing brick-and-mortar footprints by partnering with small-scale hardware and DIY stores, which can act as both showrooms and storage warehouses.
Timely delivery of awkwardly large DIY items is one of the ways that ManoMano has outshone other hardware store players. Providing appropriate delivery solutions to new DIY e-comm platforms is an opportunity.

Lick reported a $7M revenue run rate within its first eight months. Founders looking to niche down with luxury D2C options could focus on a variety of DIY markets. Some growing subreddit examples:

You could combine the thrifting and DIY trends to create an online marketplace, like a ThredUp for all things DIY.
Demand for used furniture is also growing. Your platform could have a section for used pieces, with the option to add on the tools, paints, etc. required for refurbishment.
DIY foods: There is an increasing interest in DIY food items like cheese, wine, and beer. Reddit's r/HomeBrewing has over 1M members, and TikTok's #CheeseMaking has 12M+ views.

All-you-need kits for DIY food items are an attractive opportunity, as are subscription services for seasonal options (i.e., a "make your own winter cheese" box).
Some Amazon examples already cashing in, per Jungle Scout:
FIY: The "finish it yourself" (FIY) is DIY with a safety net. This method preserves the consumer satisfaction of doing things, but with limited risk of failure.
FIY also taps into the personalization trend, and can be leveraged in a variety of ways:
