Successful investors find gaps in the marketplace and direct funds into startups and technologies resolving those gaps. For Kyra Doolan, managing director at Houston-based Texas HALO Fund, femtech represents a huge opportunity for innovation.

"A lot of the issues that face women, are things that are not talked about," she says on this week's episode of the Houston Innovators Podcast, referencing things like miscarriage, injury during childbirth, etc. "For a lot time, women just sat back if they had these issues, and they kept it to themselves, so those problems weren't being addressed."

While Texas HALO Fund has invested in femtech since its first fund in 2012, Doolan shares on the show how she personally saw an investment opportunity with kegg, a fertility tracking device. Doolan says she and other women aren't taught how to manage their own fertility journey, but it doesn't have to be that way.

"I was at a stage in my life where my eyes were open to the gaps that are out there and the conversations that weren't being had," she says. "In looking into Kegg, it showed me what the market was and how many gapes there were in the market just around fertility."

Texas HALO Fund has a few femtech companies in its portfolio now, and the most recent addition is Houston-based Work & Mother, a company that builds out fully-equipped nursing accommodations in office buildings.

Despite it's growing femtech portfolio, the fund is industry agnostic, though, Doolan says, about a third of the companies Texas HALO Fund invests in reside in the health tech space. What makes HALO different is its focus on early-stage startups.

"We like to get in early," Doolan says. "We're, what you would historically consider 'pre-VC,' but now that's getting a little bit blurred. ... We're some of the earlier capital that's invested, and we continue to make investment as the companies continue to subsequent rounds."

Doolan shares more on her passion for femtech, as well as her advice for founders looking for funding and potential female investors looking to get into investing on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.
